My present invention is concerned with gymnastic exercising machines, andhas among its objects to provide a simple and rugged apparatus,

which serves efiectively to exercise those muscles comprises a chassis or frame, which in a preferred a,

commonly used in operating a rowing machine.

An object of the invention is to provide a machine of the above type, which aifords all of the advantages of a rowing machine, and other advantages as well, but with considerable economy of floor space.

Another object is to provide a device of the above type, by which the rhythmic movements of the feet, hands, and body of the user are effectedwithout resort to transmission mechanism of the type that might become jammed or that might require lubrication service.

Another object is to provide a compact machine of the above type, smooth and silent in operation, the resistance of which may be readily adjusted a through a wide range.

' Another object is' to provide a machine of the above type by. which the user during normal operation thereof alternates from a crouched sitting position in which the trunk and arms are stretched forwardly, and the legs bent upwardly, to a substantially upright position with the arms bent inwardly towards the body.

. In apracticalembodiment of the invention a supporting frame has movably mounted thereon a seat, a handle bar and a reciprocating pedal. The three movable elements are interrelated by linkage in protected position within the frame, and are so disposed that an impulse applied by the user on any one of said movable members will cause the three members to move in a predetermined cycle relative to each other. The structure also includes adjustable resistance means preferably in the form of a hydraulic dash-pot connected to the linkage and thereby controlling the'resistancev to movement of each of the three movable elements of the machine referred to.

Referring now to the drawings, the machine embodiment includes a pair of similar parallel side frame plates l0, made of thin sheet metal, and rigidly secured together in spaced-relationship by any suitable means as for instance, cross pins Ifla fastened to said plates by machine screws 10 10b. These frame plates II) are supported at their ends respectively on legs ll, preferably, stamped from sheet metal, and provided with horizontal comparatively large feet It, having upturned edges l3 to prevent injury to the floor or rug on which the machine stands. These legs II are provided at their upper ends with extensions, shown in the form of plates I4, welded or otherwise secured to said legs, and spaced inwardly irom the side plates ill. sides of these extension plates I4 by any suitable means, such as bolts l5, and forming part of the frame structure is a pair of spaced bearing plates i8 in which are journalled the pivot pins of the various levers of the linkage mechanism, as will be more fully set forth hereinafter. These bearing-plates 18 are cross braced, by any suitable means as for instance the bolts is passing through spacer sleeves 20.

The side plates iii are shown fastened to the so bearing plates I8 and the extension plates H by machine screws 2| passing through metal bars 22 on the outer sides of said plates i0 and may. be reenforced and braced by a series of metal bars I'I, welded or otherwise secured to the inner faces thereof. The upper edges or otherwise exposed raw edges of the frame plates l0 and the ends (lag bars I1 are preferably embraced bychannels The machine includesa'seat- 24, preferably of 0 metal, which may be more or less similar to the conventional bicycle or motor cycle seat. This seat 2k is provided at its bottom with a pair of spaced fins 25, to which is pivotally connected the upper end of a lever bar 26, the lower end 5 of which is pivotally connected to the bearing plates l8 by means of a pivot pin 21 journalled in said plates. This seat supporting lever bar 26 is shown of composite construction, and comprises a pair of similarthin metal plates, rigidly held in parallel relationship at its pivot ends. The machine is also provided with a pedal 28 shown in the form of a cross piece, which is preferably covered with resilient material such as rubber, and which is long enough to permit both Secured to the inner 20* feet of the user to conveniently rest thereon at the same time. This pedal 26 is centrally connected to one end-of a rod 29, the other end of which is releasably connected by a bolt- 29a to the outerend of a lever arm 36, the inner end of which is pivoted at 3| to the bearing plate l6. B; adjusting the angular position of the rod 29 with respect to the arm 36, the desired adjustment in accordance with the leg length of the user may be made.

The lever arm 36 is shown of built-up construction similar to that of the seat supporting bar 26, and its angular movement about its pivot point 3| is transmitted to said bar 26 through the medium of a link 32. This link 32 is shown with its ends straddling the'bar 26 and arm 36 to which it is pivotally connected at 33 and 34 respectively. p

The apparatus is also provided with a handle bar 36 which may be similar to that of the ordinary bicycle or motor cycle, and which is centrally clamped in a collar 31 at the upper end of a rod 36, the lower endof which is releasably connected to the outer end of a supporting bar. '39 by suitable fastening means such as the bolts 46. The collar 31 has the usualclamping screws 4|, so that by adjusting the angular position of the rod 36 with respect to the handle supporting bar 39, and of the handle bar 36 with respect to said rod 36, the desired adjustments in accordance with the arm length of the user may be made.

The handle supporting bar 39 is shown of builtup construction, similar to that of the seat supporting bar 26, and has its lower end preferably straddling the bar 26 and pivotally connected to said bar 26 by means of a pivot pin 42, shown encircled by a spacer sleeve 43 between the side pieces of said bar 26.

In order to efiect the angular movement of the handle supporting bar 39 about the pivot pin 42, in coordination with the pedal arm 36 and the seat supporting bar 26, the lower end of said bar 39 is pivotally connected to the upper end of a lever arm 46 by a pivot pin 41 spaced from the pivot pin 42, the lower end of this arm 46 being pivotally supported on the bearing plates l6 by the pivot pin 46. This lever arm 46 is shown of built-up construction, with its upper end straddled by the lower end of the bar 39. Spacer sleeves 56 and are shown disposed between the side pieces of the lever arm and around the pivot pins 41 and 46 respectively. Suitable spacing blocks 52 are preferably interposed between the outer sides of the lever arm 46 and the bearing plates l6, to hold the linkage of the machine centrally between the frame plates l6.

The link connection between the pivot pin 42 and the pivot pin 46 is similar to that of a toggle joint, and effects angular movement of the handle supporting bar 39 about the pivot pin 42 in coordination with the movement of the seat supporting bar 26 about the pivot pin 21. These bars 26 and 39 will be limited from moving beyond the extreme position shown in dot and dash lines in Fig. 3 by the abutting of the spacer sleeve 56 against a bumper stop 49, preferably made of resilient material such as rubber, and secured between the opposite opposed side plates of the bar 26 by any suitable means, as for instance pin 49a. These side plates of the bar 26 are preferably cut away at 496 so that the sleeve 56 will come into interengagement with the stop 49 without striking a metallic part of said bar. In this stop engagingposition of the sleeve 56 the 66. The other will be substantially pivot pin 41 will be slightly to the right of the line joining the two pivot pins 42 and 46.

In order to prevent tilting of the seat 24 as it swings into the position shown in dot and dash lines in Fig. i, the seat fins 25 are pivotally connebted by pivot pin .53 to one end of a link 54, shown of built up construction, the other end of which is pivotally connected to the lower end of the handle supporting bar 39 by a pivot pin 55. This link 54 is shown straddled at its upper end by the fins 25, and straddling at its lower end the tion linkage, which serves to assure substantially a translational movement of the seat 24 parallel to itself.

In order to resist the relative displacement of the various moving parts of themachine, there is provided a hydraulic dash pot 56, which may be of any well known construction such as that of the Houdaille" shock absorber. In a specific form shown this dash pot includes the usual fluidcylinder 51 connected to the bearing plates l6 by suitable fastening means such as the bolts 56, and an operating shaft 59 extending from said cylinder and fixed to the one end of a crank arm end of the crank arm 66 is pivotally connected at 6| to one end of a link 62, the other end of which is pivotally connected to the intermediate portion of the arm 46 by a pivot pin 63 shown passing through a spacer sleeve 64 intervening between the opposed side pieces of said arm. I

Threaded centrally through the shaft 59 is the usual valve spindle 66, which extends through one of the frame plates l0, and which has connected to its outer end a suitable turning handle 61. The amount of resistance imparted by the dash pot mechanism 56 machine is regulated, by turning this spindle 66, which in turn controls the opening or closing of a. Valve port (not'shown) in the interior of the dash pot cylinder 51.

In operation of the machine it may be briefly feet on the pedal 28, 36 as shown in Fig. and 39 will extend horizontal, the seat and grasps the handle bar 1. At this stage the bars 26 substantially 45 with the 2.4 and the handle bar 36 at the same level, and the pedal 26 will be close to the underside of said bar 39 so that the user will be crouched substantially in rowing posture with the trunk and arms outstretched forwardly and the legs bent upwardly as shown in Fig. 1. In this extreme position of the operating members of the machine the link 32 will be in dead center position with respect to the pedal arm 36 (that is, the three points 3|, 33, and 34 will bein alignment) so that the transmission linkage will be self limited against movement beyond this extreme position.

The user then pushes on the pedal 28 and pulls backward on the handle bar 36. This causes the arm 36, with its attached pedal 28, to swing in counterclockwise direction about the pivot pin 3|, from a substantially vertical position to a substantially horizontal position shown in dot anddash lines in Fig. 3.

The depressing movement of the pedal 26 causes the counterclockwise rotation of the seat supporting bar 26 about the pivot pin 21 through the link 32, until the seat 24 reaches the position shown in dot and dash lines. At the same time the toggle joint connection between the pivot pins 42 and 46 causes the handle supportto the link work of the of the arm 46 about the pivot pin 48 is resisted by the hydraulic dash pot device 58, this resistance by virtue of their interconnection being im posed upon the other moving parts of the machine.

When the moving parts of the machine reach the substantially vertical dotted position shown in Fig. 3, the user will be in the upright posture shown in Fig. 2 with the legs downwardly outstretched and the arms bent inwardly. To return to the position shown in Fig. 1 the user merely relaxes on the seat 24, and releases or reduces the foot pressure on the pedal 28. The weight of the user on the seat 24 causes the seat supporting bar 26 to rotate in a clockwise direction about the pivot pin 21 into the original position shown in Figs. 1 and 3, and causes the concurrent upward swinging movement of the pedal 28, and the forward swinging of the handle supporting bar 39 away'from the seat supporting bar 26,

all of these movements being resisted by the hydraulic dash pot device 56. During this return movement the user enjoys a comparatively long period of relaxation since no affirmative effort is applied By the use of this machine, various leg, arm, back and stomach muscles are exercised by vigorous stretching and bending with alternations of afiirmative physical efiorts and relaxation .with all the benefit of a rowing machine, and further benefit similar to those derived from bending down exercises.

If the userwants to adjust the extent of physical effort necessary to operate the machine, all that is necessary is to turn the controlhandle 61 of the hydraulic dash pot device 55 to impose the desired resistance.

The machine is seen to be perfectly safe with its link work guarded between the frame plates where it cannot come into, injurious contact with the user.

' Although the mechanism is comparatively light it is yet strong and rigidenough effectively to withstand vigorously applied exercising strain. The machine is small and compact. It requires no lubrication. It is neatand attractive in appearanoe.

The use of an adjustable hydraulic dash pot device 56 rather than of a spring for imposing resistance upon the machine, results in compactness and low cost, greater ease and noiseless and smooth operation without the clatter or squeak of a spring.

Although the members of the link work have which is not only strong and rigid, but also light and inexpensive, it must be understood that as far as of the invention and is well suited certain aspects of the invention are concerned, said members may be respectively made of one piece, and may be'stamped in the form of channels.
