My invention relates to the class of devices employed for moving articles from one point to another, and more especially fordelivering articles to mechanisms for performing operations upon them, and an object of my veyer that shall be simple in construction and particularly efficient in its mode of operation. Y

One form of 4device embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- Figure 1 is a View in longitudinal section 'through one end of my improved conveyer mechanism showing its relationship with respect to a machine of which it forms a part, and which is to perform operations upon arplane of section being denoted by the dotted line 1-1 of Figure 2,

Figure 2 is aview `in cross section on a plane denoted by the dotted line 2-2 of Figure 1 with the central portion of the mechanism broken out.

My improved conveyer comprises a frame that may be constructed in any suitable manner to support the operative parts of the mechanism, as herein shown this frame comprising side bars 5 extending lengthwise on opposite sides of the frame near the bottom, said bars comprising the main parts ofthe frame and being supported in any suitable manner, as by legs, not shown. Thereside bars, as herein shown, are of angle iron, and uprights 6 aremsecured to and project upwardly therefromV at opposite ends of the frame, and crossbars 7 are supported upon and secured to said uprights at each yend of the machine, as particularly shown inv Figure 2 of the drawings A table 8 composed of sheet metal yis secured to the cross bars 7 and projects along the entire upper part vofthe frame and also extends the full width of the frame, this table having flanges 9 that serve as supports for theconveyer chain and to be hereinafter* described. A back piece 10, preferably of wood, is secured to the back side of the frame and extends for substantially its ticles delivered to it by said conveyer, theV full length and also for substantially its entire height, this back piece being secured in anysuitable manner, as by bolts.

- At each end of the side bars 5 bearings are l formed for supportingshaftsll, the shaft at mvention, amongothers,` is to provide a conone end of the frame only being shown. Sprocket'wheels A12 are secured to each of the shafts 11 at opposite sides of the frame and conveyer chains 13 are mounted upon eachV pair of sprocket wheels, said chains extending the whole length of the frame These conveyer chains are of special construction and comprise blocks 14V located between and connected by links 15, each of said blocks having lugs 16 that are received within conveyer bars 17 at each end of said bars. These bars are formed of channel iron and the blocks 14 ,are spaced sufficiently to separatefthe bars a suitable distance apart torreceive handles 18 between them, said handles being pushed along the upper surface of the table 8 by the movement of said bars caused by the operation of the chain 13. Posts 19 are secured to bolts projecting from the uprights 6 on each side of the frame and at each end thereof, and a retainer supporting rod 20 is secured to said posts at the front end ofthe conveyer.

Retainers 2l are secured to the rod 20, these being of any suitable number and projecting downwardly from the rod` and each having a retaining finger' 22 extending towardthe delivery end of the machine, as shown in Figure 1, andV preferably curved downwardly at the end to follow the curved path of the handles or other articles 18 around the sprocket wheels 12. |These lingers serve to retain said handles on other articles from out-ward displacement from between the bars 17 and a guide bar V23 is adjustably supported above vthe table 8 extending lengthwise thereof to form a path for travel of thearticles or han- .dles 18 along said table. As shown herein this guide bar is Vsecured to the lower. end of a guide bar support 24 adjustably attached to i the supporting rod 20,'as` shown in Figure 2 of the drawings. vThis adjustable mounting of the guide bar permits the width of the path for the articles 18 to be varied to accommodate articles of different length, the opposite side of said path being formed by a flange 25 on the upper edge of a cover plate 26 having the chain 13 inclosed herein at the upper edge of the machine. Means are provided for removing the articles or handles from the conveyer, and when thus removed they may be delivered, as contemplated by the machine illustrated and described herein, to a machine for performing` certain operations upon said articles or handles, as for aiiixing screw eyes thereto, the frame 27 of such a machine being partially shown in Figure 1 of the drawings herein. This removing device or ejector comprises an ejector actuating wheel 28 secured to the shaft 11 and having peripheral notches Q9 to receive an ejector roller 30 mounted on a stud projectingl from the side of an ejector rocker arm 31 'adjustably supported by an ejector shaft 32 suitably mounted for rocking movement in the side parts of the conveyer frame, there being preferably one of said rocker arms at each side of the machine, as shown in Figure 2 of the drawings, but a single actuating wheel in contact with one of said arms only, which arm is the ejector actuating arm.

An ejector plate 33 is secured to the ends of said rocker arms and projects across the conveyer at the end of the table 8. An ejector actuating spring 3ft is secured at one end to the actuating arm and at its opposite end to the frame of the machine and is employed to impart actuating movement to said arm and to the ejector to roel; said arm and ejector in one direction, in which movement the roller 30 enters one of the notches 29 in the wheel 28, a reverse movement being given to said arm and ejector by the projections between said notches on said wheel.

The ejector plate is shown in its ejecting position in Figure 1 of the drawings, from which it will be seen that the handles or articles 18 are moved outward from between the bars when they arrive opposite to said ejector, at which time one of the notches is positioned opposite the roller in the step-by-step movement of the conveyer chain.

As a means for imparting step-by-step movement to the conveyer a ratchet wheel 35 is secured to the shaft 11 and is engaged by a pawl 36 pivotally mounted on a conveyer actuating arm 37 pivotally supported on the shaft 11 and spring pressed into engagement with the teeth of the ratchet wheel, as shown by dotted lines in Figure 1.

A conveyer actuating rod 38 is pivotally attached to the actuating arm 87 at that end opposite the pawl 36, this rod comprises two sections adj ustably connected as by means of interengaging screw threads, a spring 30 attached at one end to the arm and at the other end to the frame 27 imparting idle movement to the arm 37 and pressing a roller 40 into contact with a conveyor' actuating cam i1 secured to a conveyer actuating shaft -l2 rotatably mounted in the frame 27 and operated by mechanism supported in said frame, all of the parts just above described being` shown in Figure 1 of the drawings only. The section of the rod 38 connected with the shaft i2 is forked to straddle a block of angular construction rotatably mounted on said shaft, as shown in dotted lines in Figure 1 of the drawings.

ln accordance with the provisions of the patentv statutes l have described the principles of operation of my invention, together with the device which now consider to represent the best embodiment thereof; but l. desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out.
