ED STA S PATENT LESLIE H. SIMPSONv OF SPRINGFIELD, ILLINOIS.
rests usable in connection with automobiles or the like to support the arm of the occupant in comfortable position and adapted to permit of adjustment to suit various conditions.
The purposes of the invention are; to provide a main or supporting structure of convenient form and attractive appearance adapted to be attached to the frame work of the vehicle body or adapted to be suspended on the edge of the door of the vehicle body in convenient position for use; to provide simple and effective means for vertical adjustment of a vertically movable standard carrying the arm-supporting table; to provide means for adjusting and holding the table at various inclinations relative to the standard and to provide other novel features of constrnction as will hereinafter appear.
The invention is illustrated in the annexed drawing to which reference is hereby made.
Figure 1 is a front elevation and Fig. 2 is an end elevation of an armrest embodying my invention. Fig. 3 is a top plan of the armrest; Fig. 1 is an enlarged horizontal section on the line -l-'l. of Fig. 2; Fig. 5 is an enlarged transverse section taken on the line of Fig. 1 and Fig. 6 is a reduced front elevation of the same arm support shown in Fig. 1 and showing in dotted lines one inclined position of the table. The

parts in all the views. The casing is preferably a tubular metal casting having ears 8 to receive screws 9 for connecting the easing with the vehicle body, or for connecting it with the metal hook 10: also having lugs 12 adapted to support a latch 18 as shown.
The standard 11 is adapted to slide in the casing 7 and has a series of notches 15. The
latch 13 oscillates on a pivot 16 extending through the lugs 12 and has an inwardly extended finger 17 which engages in the notches 15 of the standard 14. A spring 18 fixed on the casing acts on the latch 13 to normally keep the finger 17 in engagement Upon pushing in- Specification of Letters Patent. Patented Feb. 21, 19229 1921. Serial No. 474,450.
wardly the lower member of the latch 13,
the finger 17 will be withdrawn to permit free ad ustment of the standard. The upper terminal of the standard 14 is halved as shown in Fig. 2, to form a hinged member 19.
At'the upper end of the standard 14 is a yoke 20 connected with the standard. A bracket 21 is hinged on a rod 22 which extends through the bracket and the yoke and has a member 23 which engages on top of the yoke 20 to limit downward turning of the bracket. A hinged member 24 is integral with the bracket 21 and co-acts with the member 19 of the standard 14. A bolt 25 extends through the members 19 and 24 and is provided with a' wing nut 27. A fiber washer 26 between the members 19 and 24 prevents slipping of the parts.
If it be desired to incline the table relatively to the standard as shown. in Fig. 6, the thumb. nut 27 will be loosened and the table will be. tilted until the table 28 and the yoke 20 occupy the inclined positions shown by dotted lines 28' and 20 and when the table is properly adjusted, the nut will be tightened to keep the parts in their adjusted positions.
In order that the arm rest may be attached to the frame structure of the vehicle or to the door of the vehicle; the book 10 is detachably connected with the casing 7. If the armrest is to be directly attached to the frame structure. the hook 10 will be detached from the casing 7 by removing the screws 9 and ordinary wood screws inserted through the same holes in the ears 8 will be used to connect the casing with the frame structure.
IVhen the armrest is in place, either on the frame structure of the vehicle, or on the vehicle door, the table 28 may be turned upwardly on its hinge 22 to an approximately vertical position 28' indicated by dotted lines in Fig. 2, and when the table is in its raised position as described, it will be out of the way and will not discommode occupants of the vehicle.
In use; the latch 13 will be operated by hand to disengage it from the notches of the standard and permit the standard to be moved upwardly or downwardly to the desired position, whereupon the latch being released, the table will be supported in the desired position.
I have shown and described screws engaging the ears 8 to detachably connect the casing with the vehicle, I have also shown and described a hook 10 adapted to engage the same ears for the same purpose; Itherefore do. not restrict my claims to precise means for attaching the casing to the vehicle.
Having fully described my invention What I claim as new and desire to secure by Letters Patent is:
1. An armrest for vehicles, comprising a tubular casing having laterally extended ears, a longitudinal slot and outwardly-extended lugs adjacent to the respective sides of the slot; a notched standard slidable vin the casing; a latch pivoted on the lugs of the casing and adapted to engage in the notches of the standard; a spring acting to keep the latch engaged in the notches of the standard; a yoke at the upper end of and pro-' jected outwardly and laterally beyond the standard and having a fiat top; a bracket supported on the yoke and having a downwardly-extended member adapted to engage on the top of the yoke to limit downward rotation of the bracket; a table fixed on the bracket; horizontal hinges connecting the bracket with the yoke and admitting of raising the table to an approximately vertical position; a horizontal swivel at right-v angles to the axis of the hinges and admitting of inclining the table transversely relatively to the axis of the casing; and attaching-means co-acting with the ears of the casing to detachably connect the casing with the vehicle.
2. An armrest for vehicles, comprising a casing having lateral ears; a table supported on the casing and movable vertically and inclinable forwardly and laterally relatively to the axis of the casing; and attaching means co-acting with the ears of the casing to detachably connect the casing with the vehicle.
