ARM-REST.

Specification of Letters Patent.

Patented Oct. 13, 1908.

Application filed September 25, 1906. Serial N 0. 836,105.

and State of Pennsylvania, have invented certain new and useful Improvements in Arm-Rests, of which the following is a specification.

This invention concerns arm-rests for seating and particularly for such seating as is commonly employed in railway cars. ()11 ac count of the conditions under which these cars are operated, it has been considered highly desirable to make the parts thereof 'and of the seats used therein entirely of iireproof material The object of my invention is to providea fireproof armrest for such seats which is simple and strong in construction and attractive in appearance and which can be manufactured at small cost.

In order to secure the desirable feature of incombustibility, the arm-rest may be made wholly of metal, but as th e hand and arm of an occupant of the seat are rested upon the upper surface of the arm-rest and might be come chilled thereby if it were of metal, I make the up er portion of the arm-rest of some materia which, while being incombustible, is non-metallic. For this purpose, fiber or paper may be employed, but I prefer to use wood, this being impregnated with a lireproofing compound to make it incombnstible.

I have illustrated an embodiment of my invention in the accompanying drawings, in which 4 Figure 1 is an elevation of the arm-rest, Fig. 2 is a section thereof on line 2*2 of Fig. 1, and Fig. 3 is a view similar to Fig. 2 illustrating a modification. I

Referring to these drawings, the arm-rest is shown as consisting of two parts, an upper and a lower one, the former being made of a non-metallic, incombustible material and the latter of metal. The lower part 1 is made of sheet-metal which when out to the proper dimensions is pressed into form to provide a closed bottom ortion 2 and an integral upwardly-exten ing flange 3 about the edges thereof. The distance between 0 .posite sides of the flange 3 is greatest at t 10 top thereof so as to form a shoulder 4 and below this another shoulder 5 is formed, thus ,providing a tongue 6 at the bottom of the part. The upper part 7 is preferably of wood and is impregnated with a iireprooiing compound; it is of comparatively small thickness so that the iircprooiing will be effectual. The upper surface of the part 7 is given the curvature desired for the upper surface of the completed arm-rest and its edges are rounded oil. At its lower edges the material is cut 1 away to provide a downwardly-extending tongue 8.

The two parts for the armrest, thus constructed, are assembled as shown in the drawing. The tongue 8 on the bottom of the part 7 is forced into the part 1 between the sides of the flange 3 until its lower edge rests upon the shoulder 4 and the upper edge of the llangc engages the shoulder at the upper end of the tongue 8. The clamping action of the metal will be sullicicnt to ho d the two parts together in this relation but, if desired,.additiomll securing means may be provided. Such an arm-rest is usually .emf plo ved with a metallic seat-end consisting 0- two sheet-metal plates pressed to the desired form and secured together with open space between them. These plates are shown at J and H). The arm-rest is mounted thereon by forcing the tongue/6 down into the open upper end of the. seat-end between the plates 9 and 10 a distance limited by the length of the tongue when the shoulder 5 will engage the upper edges of plates 9 and 10 and prevent further movement. The width of tongue (5 may be such relatively to the distance between plates .l and 10 that the armrest will be held 'lirmly in.position on the seat-end without the cmplovment of additional securing means, but such means may be provided if desired.

In Fig. 3, .I have illustrated a slight modification of the arm-rest shown in Figs. 1 and 2, in which the part 7 of the arm-rest made of V fireproofed wood is covered with a fabric 11. Any suitable fabric may be employed, such as canvas or plush impregnated with a fireroofing compound to make it incombustiiile. This covering is secured at its edges to the part 7, as b small tacks or cement.

Having now escribed in Y invention, what I claim as new therein and esire to secure by Letters Patent is as follows An arm-rest comprising an upper part formed of non-metallic material and a lower part made of metal, said upper part having. a

" tongue on the bottom thereof entering within the lower part, and the side walls. of said WHY "Jil (k. MENU shoulders, and. mean' for sccuixw wsi'
