HEAD-REST FOR CAR-SEATS.

SPECIFICATION forming part of Letters Patent No. 365,248, dated June 21, 1887.

Application filed February 3, 1887. Serial No. 5226, 102.

To all whom it may concern.-

Be it known that I, H. XVALTER FAOKRELL, a citizen of the United States, residing at Belleville, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Head-Rests for Car- Seats; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the-art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention is designed to provide a rest for the head on the seats in railway-cars, which when in use affords a comfortable support for the head, and when not in use may be readily removed or put out of sight, thus restoring the seat to its ordinary condition, and which is always at hand ready for use.

In the accompanying drawings, Figure 1, Sheet 1, is a side elevation of a car-seat, from the back of which my improved rest is shown to project. Fig. 2 is an elevation of the interior of the back of the car-scat, indicating the arrangement of the head-rests therein and the construction and relation of the mechanism for operating the same. Fig. 3, Sheet 2, is an enlarged view of one of the rests and its actuating mechanism. Fig. 4 is a sectional view of a portion of the frame, grooved rack, 850., of the rest taken through 00, Fig. 3, and a top View of a portion of the spring-actuated cogwheel. Fig. 5 is a section taken through 1, Fig. 3. Fig. 6 is an elevation of the interior of the spring-actuated cog-wheel and a section of the supporting-bracket. Fig. 7 is a view of ajournal plate of the cog-wheel. Fig. Sis a perspective View of a shaft, to which one end of the spiral spring arranged in the chambered cog-wheel is secured and upon which said wheel turns; and Fig. 9 is a similar view of a finger-plate secured to the top of the headrcst. On Sheet 3, Fig. 10, is a view, similar to Fig. 3, illustrating a construction in which the ratchets and cogs are dispensed with.

In the above-described views, A indicates the outside frame portion of the back of the carseat, and B and O the intersecting interior (No model.)

braces of the same, respectively. In each of the four divisions of the interior of the back a head-rest and the mechanism for actuating the same are arranged substantially as indicated in Fig. 2, two of said rests being arranged so as to project from one edge of the back and the remaining two from the opposite edge thereof.

The head-rest, illustrated more in detail in Figs. 3 and 4, consists of a frame of suitable shape, having the grooved side strips, (1, and the erosspieces d (1 across which is tightly stretched a cloth covering, 0-, or other material of suitable strength and finish, the said eov ering extending preferably out to the edges of the frame-pieces, or over the same if desirable, in order to hide that portion of the rest, as shown in Fig. 4. lVithin the grooved side strips of the frame are secured grooved racks consisting of the toothed portions f, between which is formed a groove, j", which is preferably undereut, as indicated in Fig. 4, the extremities of the teeth in the rack. portions f being flush with or countersunk below the outside of the sideframe strips (1.

Fastencd to the frame portions A and G, as indicated on the left in Fig. 2 and in Fig. 3, or extending continuously through the cross piece a, as shown on the right in Fig. 2, are ways h, which lie in the groovef, as in Fig. 4, and act as guides to direct and control the movement of the sliding head-rest, said ways or strips conforming in cross-section to the groovef',to prevent any looseness or rattling of the parts.

The head-rest may either be thrown up antomatically from the seat by suitable mechanism, one form of which is illustrated in the drawings, and depressed or returned into the seat by hand, or the mechanism shown in said drawings may be reversed, so as to return the rest into the seat automatically, while the same is lifted from its receptacle by hand by means of a suitable finger-piece, 1, indicated by dotted lines on Fig. 3, and shown in perspective in Fig. 9, detached from the rest.

YVhen constructed as shown, the rest-lifting mechanism consists of a cog-wheel, j, the teeth of which mesh with the rack on the sliding rest, and provided with aehamber, j, within which is arranged a spiral spring, j one end. of which is fastened to the chambered wheel, as at j Fig. 5, the other end ofsaid spring be ing secured to the stationary shaft in, as at 70, Fig.5. A plate, j", closes up the open side of the chambered wheel and through said plate, and the opposite side of the wheel the shaft 70 projects into the depending hangers Z Z of the bracket L, one of said hangers, as Z, being removably secured to the top of the bracket to permit the removal and insertion of the chambered whee1,as will be understood by referencc to Fig. 5. One end of theshaft 7c is squared to fit in a square opening in one of the hangers, so as to hold said shaft stationary while the chambered wheel is turning to wind up the spring around the shaft.

Du ring the downward movement of the headrest the chambered wheel is caused to turn in the direction indicated by the arrow in Fig. 6, thereby winding up the spring; and when the rest reaches its lowest position and is enlirely within the seat, as indicated in Fig. 3,

. a spring-actuated plunger,m,working through a perforation, h, in the way h, engages an opening, in the grooved racks, as shown in Figs. 1 and 4., and holds the head-rest down within the seat.

Upon the withdrawal of the plunger from the openingf the power of the coiled springs throws the rest upward from the seat, as shown in Figs. 1 and 2, the extent of the projection of the rest being limited by the stop-piece d, which strikes the under side of the frame portion A of the seat. Any other form of stop which will answer the purpose may be used in lieu of the cross-piece d.

For operating the spring-actuated plunger so as to withdraw the same from holding-engagement with the rack, a lever, n, pivoted at n to an arm, of, is used, one end of said lever being pivotally attached to the plunger and the opposite end to a finger-piece, of, projecting out through the side of the seat, as in Fig. 3, at which point is arranged a recessed plate, a, which presents a finished appearance and provides a receptacle for the button a when depressed.

Instead of providing the stop d to limit the upward movement of the rest, a series of openings similar to f 2 may be formed in the grooved rack or in the frame of the rest, with which the plunger engages automatically and the rest permitted to project upward as far as may be desired.

While the mechanism illustrated in the figures of the drawings for communicating the lifting-power of the spring to the rest and for winding the spring is advantageous, on account of its strength and positive action, I may dispense with the teeth on both the rack or grooved plate and the chambered wheel and use instead a strap, 0, fastened at one end to the outside of the said wheel in the groove and wound therearound, the other end of said strap being carried down and fastened to a from the spirit of my invention.

cross-strip, 0, extending across the grooved plate outside of the ways 72, as dotted on Fig. 3 and as indicated in Fig. 10.

Around the opening in the top of the frame A, through which the restproj ects, is arranged a plate, 19, as indicated in Fig. 3, and through the top of said frame a bolt, q, passes, which secures the brackets Z in their proper position. These features, as well as other details of construction, may be varied without departing If desirable, the head-rest may be cushioned to render the support more comfortable, as will be understood.

Having thus described my invention, what I claim as new, is-
