Toal l ibhdzi t ntwywncervt. I v v Be it known that I, JAMEs SHERIDAN, aciti zen of the United States, and a resident of Lawrence, county of. Essex', and State of Massachusetts, have invented certain new and useful Improvements in Combination Chai-rs, of which the following is a specification.

I This invention relates particularly to an improvement upon a construction described and claimed in a patent granted to myself and J. WV. McNalty August 27, 1895, No. 545,417. This chair was found to be defective in sev: eral. particulars, which defects it is the object of this invention to correct. In thep'atent the means for holding the chair in the high position was inconvenient to operate and insecure. l have substituted for such means an automatic means for holding the chair in thenhigh position, togetherwitha convenient and simple means for releasingsuch holding means, so that the chair may be. readily lowered. The looking or adjusting lever of the patent, which was used to hold the chair at difierent inclinations, was also found impracticable, and I have therefore discarded this lever and substituted a means which is considerablysiinpler. Theindependentfoot-rest of the patent was found objectionable when the device was used as a swing-chair, and I have improved the present device by hinging the foot-rest to the chair-seat. I

For a more complete disclosure of my 19",

vice reference is made to the accompanying drawings, in which- Figure 1 is an elevation showing the lefthand side of the chair; Fig. 2 is a plan view of the bottom side of the seat. Fig. 3 is an portion detached. Fig. 4 isa cross-section j eeoft ie idasupp rts '6 e i 'ds; Fig-15showsaplan-wew of. an

" I may be provided with casters, as show-n1} ,Si'de 'The base 1 is supported 011' legs 2,;which' bars'or standards 3 3 extend vertically from the base to any desiredflheight, The chair portion consists of the usual ,seatA, arrnso, back 6, and ronndsjfi; Parallel rods 8 8 extend from theseat to the arm on each side of the chair. Each of the standards 3 disgprovided near its upper end with bolts 9, having heads 10, each bolt being held in position on said standards by a collar 11-, which bears against a shoulder on the bolt, and nut 12, which is screwed thereon, engaging opposite sides of the standards. The diameter of the bolts is such as to permit them to fit andslide nicely between the rods 8 8. The space between the head 10 and collar 11 is made about equal to the diameter of the rods 8. The sides of the seat halveplates 12 and 13 secured there to, the plate 12 having a notchl lcut'tlierein and the plate 13 havingalike notch 15 (shown;

in dotted lines in .Fig. 1) "directlyopposite thereto. :Catches 16, havingbeveled ends, as

shown, are arranged iii said. standards 3a short distance below the bolts 9, said. catches being pressed out of their sockets by-springs.

17 and their ends projecting beyond the'inner sides .of the standards a suflicieutdistanoe to engage the notches 1t 15 automatically when thechair is drawn up-to the high position. When the chairis thus drawn up, the

upper edge of the plates. will strike the-bow 3 eled portion of the spring-catches, forcingthe same back into their sockets, and when X the catches come opposite the notches they will spring out and hold the chair in the high position, as will be obvious. To force these catches back to permit the chair to be lowered, I provide the following mechanism; Levers 20 arepivoted at 21 on the underside of the seatrof the'chair, each of said levers being provided near one endwitha projection 22, which is adapted to enter the notches in the plates: Each of the links 23 is pivoted at one end to-the opposite-end of said levers 2d and at the other end to a springpressed bolt 24 by means of a pin 25'. Said bolt 2e passes through a; bracket 26 and base, spring 27 hereo which antsh weenseid bracket. an

the ends ofsaid. links and draws the pin 2ft inwardly, thus drawing the projections 22inwardly. By drawing the pin 24 outwardly the projections will be forced into the notches; and if the chair is in its high posi tion they will engage the ends -of the springcatches', forcing them back into their sockets, softhat the chair may be readily and easily lowered. By providing thenotches in plates 12 and 13, into which the spring-catches must project in order to hold the chair in an elecatches is made positive.

'pintle 29.

A plate 28 is secured to the under side of the seat and has its front end bent around a An arm 30 is pivoted on said pintle and carries at its opposite end a foot-rest 31. This pintle 29 also carries a ratchetwheel 32. A pawl or sliding catch 83 is arranged to slide on the under side of said plate 28 and to engage said ratchet-wheel 32. Said pawl is held-in place by and slides on a pin 34, which passes through the angular projection of the pawl. The opposite end of pin 3% from the pawl isflfixed in the angular proje'ction 36 on plate 28, and a spring 3'1". on pin 34 between projections 35 and 36 forces the pawl into engagement with the ratchet. The arm 31 is provided with a notch 38,'in which the ratchet-wheel is held, said wheel engaging the edge 39 of notch 38, so that said ratchet and bracketmust move together. To chan go the adjustment of the foot-rest, it is simply necessary to (1: 1w back the pawl 33 from the ratchet and move the foot-rest to the desired position, after which the pawl, being released,

. will hold the foot-rest in the new position.

- which the bolt 40 passes.

The standard 3' is provided with a bolt 40, which is arranged to engage the apertures 41 in the side plate 13. Plates 4) and 43am secured to the sides of standard 3, through The plate 42 is provided with an aperture into which the small end portion of the bolt 40 fits. The plate 43 has an oval or oblong aperture through which the oval or correspondingly-shaped central portion 40 of the bolt is adapted to pass. A spring 44 is interposed between plate 42 and the enlarged portion 40 of the bolt. When the bolt is pressed inwardly, so as to engage the apertures 41 of the side plate, the bolt may be turned so that the enlarged oval portion 40 thereof is in the vertical position shown. in Fig. 4. in this position one end of the oval portion bears against the inner side of plate 43. When the bolt is turned so that the oval portion thereof is horizontal, as shown in the detached view of the bolt in Fig. 4, the oval portion may pass through plate 43 and will be held in its withdrawn position by the spring 44. \Vhen the bolt is withdrawn, the chair may be used as a swing, and by pressing the bolt inwardly, so thatit may engage the apertures 41, the chair may be held at the several inclinations corresponding thereto, as will be obvious.

Sliding bolts 45 and 46 are secured to the under side of the seat at opposite corners and near the front and rear thereof, respectively, so that they will project beyond the side of the seat and engage the sides of tie-standards, thus preventing the chair from swinging too far.

Acircular portion 47 is cut out in the seat, which on being removed will adapt the chair for use as a walking chair, as in the former patent, and said circular portion is alsoprovided with the drop-lid is, which will permit the use of the same as a commode-ornurserychair. 'In connection with this latter use I provide an insertible-support 49 for achamber vessel. This support is provided with notched ends 50, which are adapted to engage the standard when itis placed in between the same. The flanges 51 on the edges of the sup port serve to keep the vessel in place.

A tray 52 is hinged on pin 53 so as to swing vertically and is held in place by sliding bolt 54.

' From the above description it will be seen that a chair made in accordance with my invention may be readily changed from a low to nhigh chair, and vice versa, without loosening or tightening any nuts and that I have provided a simple means' for changing the chair to a swing-chair or holding the earnest different inclinations. By providing an adjustable foot-rest which is secured directly to the seat the chair is considerablyimproved over the construction of the patent above referred to, as .in whatever position the chair v is placed the foot-rest will be in 3. corresponding position.

Having described my invention, what I claim as new, and desire to secure by Letters Patent of the United States is as follows:

1. A combination-chair, consisting of a base,standards carried thereby, an adjustable seat arranged to slide vertically between said standards, notches at each side of said seat/10o spring-catches carried by said standards which are arranged to project inwardly and engage said notches and hold said seat in an elevated position, levers pivoted to the under side of said seat, projections carried by said levers which are adapted and arranged to enter said notches and engage said catches, and connections between said levers whereby said levers may be moved simultaneously, substantially as described.

2. A'combination-chair having a base portion, standards carried thereby, an adjustable seat arranged to slide vertically betweensaid standards, spring-catches arranged in said standards, said catches'projecting from the inner sides thereof and being adapted and arranged to automatically engage the seat when it is raised and to hold it in its raised position, levers pivoted to the bottom of said seat, a link pivoted to the rear end of each lever, a pivoted connection between the opposite ends of said links, means for moving said pivotal connection, PIOJGCUOUS carried by said levers which upon movement of said pivoted connection will engage said catches and press them into said standards out of engage'ment of said seat, substantially as described.
