CAR-SEAT.

SPECIFICATION forming part of Letters Patent No. 443,311, dated December 23,1890. Application iiled March 7, 1890. Serial No. 343,042. (No model.)

To @ZZ whom it may concern.-

Be it known that I, WELCOME B. BEAL, of Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Car-Seats, of which the following is a specification.

This invention has for its object to improve the construction of the fixed end pieces or frames of railway-car seats and ot the arms or brackets which are attached to the reversible backs of suoli seats andare pivoted to the said end frames.

In car-seats now in general use the arms or brackets attached to the back are comparatively narrow and lare pivoted to the end frames at points considerably below the upper edges or arm-rests formed on said end frames, so that when the back is being reversed the arms or brackets move across the edges of the arm-rests in a manner not unlikev the action of a moving shear-blade co-operating with a fixed shear-blade. It often happens, therefore, that iin gers of passengers are caught between the fixed end frames and the arms on the back and are seriously injured thereby. Moreover, the present construction is such that the clothing of passengers is often caught and torn.

My invention obviates the objections above referred to; and it consists in the improved construction which I will now proceed to describe and claim.

In the accompanying drawings, forming a part of this specification, Figure l represents a perspective view of a car-seat embodying my invention. Fig. 2 represents a transverse section of the same, looking toward one of the ends. Fig. 3 represents a section on the line 3 3, Fig. 2.

The same letters of reference indicate the same parts in all of the figures.

In carrying out my invention I construct the fixed end frames d a of a canseat in the form of comparatively thin plates presenting circular or-approximately circular edges at all parts excepting their lower portions, on which are formed the arms d ,which connect the said end pieces with the supporting. portions c2.

b b represent the arms, which are attached to the back c. These arms I connect to the end frames by pivots d d, which are located substantially equidistant from the upper and sideedges of said frames. I make the arms or brackets Z9 b of sufficient width to extend to the upper and forward edges of the seatframes from the pivots d d, the upper edges of vsaid arms being practically flush with the corresponding portions of the end frames a a, as shown in Figs. l and 2, said arms being extended outwardly in all directions from said pivots, so that when the back c is being reversed there can be no shearing movement of either edge of the arm across the corresponding edge of the corresponding end frame. The adjoining sides of the end frames and arms are provided with circular grooves e, which are concentric with the pivots d. Said grooves contain a series of spherical anti-friction rollers or balls f, which are in contact with both the end frames d and the arms l) and constitute ball-bearings, whereby the arms are enabled to be easily turned to reverse the seat-back, said ball-bearings preventing the arms from bearing directly on the end frames, so that the arms can be swung upon their pivots with the minimum of resistance caused by friction.

The armsb are provided with stops g, which are adapted to bear against portions of the end frames and support the arms and the seat-back in either of the positions to which the back may be turned, each arm having two stops, one of which bears against one edge of the corresponding end frame when the back is in one position, while the other bears against the opposite edge when the back is reversed.

It will be seen that the form of the arms b and of the end frames is such that there is no possibility of either edge of an arm b moving across the corresponding edge of t-he main frame a in such manner as to make -injury to the lingers of passengers possible. Hence there is no possibility of the hands or lingers of passengers being caught between the edges of the end frames and the edges of the arms.

The end frames support the seat-back by contact of their marginal portions with the stops gg on the arms. Hence the usual hooked lugs projecting inwardly from the end frames as a means for supporting the seat-back arms are not required. The said hooked lugs are, as is well. known, a source of annoyance, be-

IOS

eanse they frequentl)Y eateh and tear the clothing et passengers. This objection is entirely obviated by my improvements.

The end trames and arms maybe llat in eross-seetio1i,or they mayv be eoneavo-eonvex or of any other desired form.

I claiml. In a railway-ear seat, the Combination of the rigid end frames at the ends of the seat and the wide back-supporting,l arms pivoted to the end frames at points about equally distant from the top and side edges of the latter7 said arms being widened or extended latererally from said pivots, so that their upper edges will be substantially flush with the upper edgesof the end frames in either position of the back, as set forth.

2. In a railway-ear seat, the combination ot' the end frames or plates and the wide bael supporting arms pivoted to the end frames at points about equally distant lfrom the upper and side edges of the latter and extended from the connecting-pivots, so that their upper edges and ferwardends are substantially llush, respeeth'ely, with the upper and forward edges of the end frames, as set forth.

il. ln a railway-ear seat, the combination of the end frames or plates7 the wide back-supporting,r arms pivoted to the end trames at points about equallly7 distant from the upper and side edges of the latter, said arms beingr extended in all directions from the supporting-pivots, as described, and anti-friction balls or rollers interposed between said end frames and arms, said rollers being,r arranged eoneentrieally with the pivots that connect the said frames and arnls, as set forth. l

ln testimony whereof I have signed my naine to this specification, in the presence ot' tu'o subscribingY witnesses, this 98th day of lfebruary7 A. l). lStN'l.
