UNTED STATES PATENT OFFCE
PETER A LA FRANCE AND J D DNSMORE OF ELMRA NEW YORK
MPROVED HEADREST FOR RALWAYCARS
Specification forming part of Letters Patent No 57 dated September 11 1866
To all whom it may concern:
Be it known that we PETER A LA FRANCE and JOSEPH D DNSMORE of Elmira in the county of Chemung and State of New York have invented a new and useful mprovement in Portable HeadRests for RailwayCars and we do hereby declare that the following is a full clear and exact description of the construction and operation of the same reference being had to the annexed drawings making part of this specification in which
Figure 1 is a perspective view Fig 2 is a vertical transverse section showing the mode of attaching the parts and Fig 3 is a detached view of the button by which the parts are united
The same letters are used in referring to identical parts
A and A' are angular pieces the upper part of A' forming an obtuse and the same part of A forming an acute angle with the stem The upper face of the piece A has flanges turned up on the edges which are made convergent to receive the upper part of the piece A' the sides of which are sloped to the angle of the flanges of the piece A The two pieces are thus joined adjustably forming jaws which may be adapted to the backs of carseats of various thickness The two pieces are each formed with slots cut from their upper ends back toward the stems n these slots are inserted the shank of the stud B which by its stress retains the pieces in their relative positions as will be more fully explained The lower head of the stud B is rounded so as not to injure the backs of the carseats The upper head of the same is elongated as shown in Fig 3
C is a semicircular headrest which is adjustably attached to the jaws by the stud B the head of which is inserted through longitudinal slots C' and C" in the headrest n the middle of the rest C a slot of the same width as C" is cut perpendicularly thereto to the center of the rest The edges of this slot as also of the head of the button should be beveled so that when the pieces A and A' are united and the stud B inserted into the slots in the pieces A and A' and also in the headrest C when the latter is turned the head rising upon these inclinations the parts shall befirmly united This union is made still more perfect by the strain of the seat upon the jaws A and A' which being forced apart below draw more firmly on the stud The headrest maybe thus disposed immediately behind the head of the passenger or may be supported at either end so as to enable the passenger to vary the position of his head an desired
D is a cushion with which the headrest is lined This cushion may be sewed on by passing the thread through the perforations D' in the plate C
E is a pad attached by elastic straps E' which pass through eyes in the ends of the rest and are buttoned to the buttons F This serves when desired for an elastic rest for the head The tension of the straps must be such that the head shall not force the pad E back against the rest C
The straps E' are made ordinarily of any suitable nonelastic material united with a short elastic piece adjoining the pad sufficient to give the requisite elasticity to the strap
The rest may be attached to the arm of the carseat and the straps E' attached so that the pad E shall hang below the arm to receive the head of the passenger This mode of application will be found especially desirable on cars where the arms are high enough to permit its application when the passenger has an entire seat that he may lie upon longitudinally
nstead of the separate jaws A A' made and united as described the jaws may be made in a single piece having the same form as the jaws A A' when united n this case the portions of the jaw clasping the front and back of the back of the seat should be made elastic so as to compress by their tension and retain afirm hold upon the back of the seat and so as to be adaptable to seats of different thickness For this purpose the jaws should be made of steel or other elastic material
What we claim as our invention and seek to secure by Letters Patent is
1 A portable headrest constructed with adjustable jaws A A' supporting a curved headrest C said parts being respectively constructed and combined for use substantially as set forth
2 The semicircular headrest C when constructed with slots for receiving a stud B by
which it is adj astably attached to the jaws A the top face to which the headrest is attached A' substantially as set forth
3 The pad E suspended upon elastic straps E' when used in combination with a headrest substantially in the manner and for the parpose set forth
4 A portable headrest for attachment to the backs or arms of the seats of railwaycars when so constructed that the jaws by which it is so attached shall form the front piece an obtuse and the hind one an acute angle with
substantially as set forth
n testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses
