' EXTENSION I-TANDLE FOR CONTROL LEVERS.

Application filed Apri124, 1926. Serial No. 104,417.

This invention relates to extension handles for control levers and more particularly to an extension handle for the emergency brake invention is to provide a device of this character, particularly adapted for those vehicles of the coach type having a folding seat which necessitates arrangement of the emergency brake handle at a position in advance of the usual position and accordingly at a point where it is substantially inaccessible in order that the shiftable seat of such VG". hicles may be placed in its folded position to enable the passage of occupants of the vehicle. It will be obvious that a handle of this character must be capable of being p0"? sitioned so that it will not interfere with the folding of the seat and a further object of the invention is the provision of a handle so constructed.

These and other objects I attain by the construction shown in the accompanying drawing, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a side elevation partially in section of an extension handle constructed in accordance with my invention showing the same applied to a lever;

Figure 2 is a rear'elevation thereof; 7

Fig. 3 is a section on the line 33 of Figure 1;

Figure 4 is a section on the line H of Figure 1;

Figure 5 is a section on the line 55 of Figure 1.

Referring now more particularly to the drawings, the numeral 10 generally indicates a pivoted brake lever having associated therewith a latch 11 coacting with the seg ment 12 to maintain the brake lever in ad justed positions. These latches are provided with links 13 which, in the usual construction of the lever, are connected with a latch lever (not shown) which is, in turn, pivot- ,flange 23 of a channelmember 2 1.

ally connected, as at 14:, to a flattened por-. tion 15 provided upon the upper end of the lever.

In accordance with my invention, I provide a lever consisting of a pair of arms 16 adapted to flatly engage opposite sides of the flattened portion 11 of the lever l'O and combining at their outer ends to .produce a solid handle portion 17, the terminal of which is downturned, as indicated at 18, and provides the actual hand grip. The arms 16.

are provided with pairs of aligned openings 19 spaced longitudinally of the arms, one

of the pairs being employed for. the reception of a pivot bolt connecting the arms of the lever 10 at 14. In a secondse lected pair of openings 19 a second bolt 20 is directed adapted to pivota-lly receive the eye 21 at the upper end of an extension 22 of one Intermediate the ends, the flanges of this channel member are provided with aligned openings for the passage of a pin 25 adapted to be received in anotch 26 formed in the convex face of a bowed spring 27, the end portions 28 of which oppose the bightof the channel member and retained there against the pull rod 13' of the latch 11. This spring prevents rattling of the pull rod as'well as serving to maintain the pull'rod in proper position.

The-enlarged upper end 29 of the pull rod, as the handle 18 is elevated, will come into engagement with the upper'ends of the flanges of the channel 24 and thereafter will move with the flanges with the result that the latch 11 is elevated and the lever 10 freed for movement. This may be caused through the handle 18. It will be obvious that the handle 18, since it extends considerably rearwardly of the lever 10 will be much more readily accessible to the operator of the vehicle thanthis lever and accordingly will permit the emergency brake lever to be applied with much less exertion and loss of time. It will also be obvious that because of the sliding connection provided between the pull rod 13 and the handle 18, this handle may be foldeddo-wnwardly so that the arms 16 willlie substantially parallel to the lever 10. In order to permit a maximum movement of this other handle, the handle is slightly offset, as indicated at 30, to permit it to pass to that side of the leverlO next adjacent the driver of the vehicle. When in this folded position,'the

extension handle will in no way interfere with folding of the movable seats of coach type vehicles.

It will be noted that by the use of a plurality of pairs of openings 19, the lever may be readily adapted for use in combination with the emergency brake levers of different makes or types of vehicles.

Since the construction hereinbefore set forth is capable of a certain range of change and modification without materially departing from the spirit of the invention, I do not limit myself to such specific structure except as hereinafter claimed.

I claim:

1. In combination with a lever, a latch associated with the lever for retaining the lever in adjusted positions and a pull rod for said latch, a handle pivoted to the lever and extending outwardly at substantially right angles thereto, the outer end of the handle providing a hand grip, ,a member pivoted to the handle and slid'ably embracing said pull rod, the upper end of the pull rod having astop engaging with said member when the handle is elevated to a predetermined degree.

2. In combination with a lever, a latch associated with the lever for retaining the lever in adjusted positions and a pull rod for said latch, a handle pivoted to the lever and extending outwardly at substantially right angles thereto, the outer end of the handle providing a hand grip, a member pivoted to the handle and slidably embracing'saidpull rod, the upper end of the pull rod having a stop engaging with said member when the handle is elevated to a predetermined degree, said member having in its low erend a channel receiving the pull rod and a spring carried by the member and abutting the pull rod to maintain the same in engagement with the inner wall of the bight of the channel.

3. In combination with a lever, a latch associated with the lever for retaining the lever in adjusted positions and a pull rod for said latch, a handle pivoted to the lever and extending outwardly at substantially right angles thereto, the outer end of the handle providing a hand grip, a member pivotedto the handle and slidably embracing said pull rod, the upper end of the pull rod having a stop engaging with said member when the handle is elevated to a predetermined degree, said handle being transversely offset to thereby permit the hand grip to move past the lever so that said handle may approximately parallel the lever.
