CLUTCH-OPERATING nnvrcn.

Application filed April 15, 192 Serial No. 154,057.

ence to a hand actuated extension lever which has operating connection with a clutch pedal and which is located in close proximity to the drivers seat for more convenient manipulation. I i

My principal aim is to provide a comparatively simple and inexpensive arrangement of parts which are associated in a manner to make for convenient operation, and which are constructed to permit themato be mounted upon the machine without requiring alterations of the existing stock parts. 1

The details, as well as their novelorganization will be quite plain from the following descri tion and drawings. t

Int e drawings Figure 1 is a side view of the complete device or attachment, showlng the method in which it is placed in position, and how it cooperates with the clutch pedal.

Fig. 2 is an enlarged section taken approximately upon the plane of the line 22 of Fig. 1, looking downwardly.

Figs. 3, 4 and 5 are perspective views of the details as they appear when separated.

Fig. 6 is a detail sectional view showing the pin and slot connections between the lifting link and clutch pedal clamp.

In the drawings, the reference character 1 designates the ordinary clutch pedal while the reference character 2 designates the operating rod which is connected therewith.

One of the main features of the improved attachment is the elongated lever 3 which has an upturned extremity 4 providing an operating handle which is located within con venient reach of the drivers seat. This leve is pivotally mounted between its center and the forward end on a supporting bracket 5. This bracket, as better shown in Fig. 5, comprises a vertical upright 6 having an outwardly offset extremity 7 with which the lever is pivotally connected, as shown. This bracket also includes a horizontal extension 8 which is fastened to the frame of the machine in any appropriate manner.

The forward end of the operating lever is pivotally connected to the upper end of a. lifting link 9. This link is better shown in Fig. 4, and comprises a section 10 withwhich the lever is pivotally connected, an outwardly offset intermediate portion 11, and a depending extremity 12 having an elongated slot 13. The slotted end 12 is connected with the clamp let through the medium of the pin 15, (see Fig. 6 pp The purpose of thispin and slot connection will be hereinafter described.

, This clamp is made up of a pair ofmetal straps 16 which are fastened together, and

which have a fork atthe rear end, the arm 17 of this fork (see Fig. 2),straddlingthe lower end of the link, beingconnected tliereto by the aforesaid pin 15. From Fig.1,it will be noted that the forward end of the clamp terminates in a pair of outwardly converging portions which are formed to provide clamping jaws 18 which surround and i are fastened to the shank of the pedal 1.

Thisclamp forms what functions as a rocker arm for the clutch pedal, the rocking motion being provided by the vertical movement of the lifting link 9. This vertical movement is of course provided by way of operation of the lever 3.

A suitable retaining device is provided for the lever, this being shown better in Fig. 3. It comprises a standard 19 fastened to the frame of the machine at an inclined angle as shown. 011 the inner side, is a metal retainer 20, which has its opposite ends 21 and 22 bent outwardly to provide upper and lower keeper seats for the handle forming end of the lever.

The disengaged position of the clutch is shown by the full lines and the engaged po sition is shown by the dotted lines. Obviously then, when it is desired to hold theclutch pedal in the disengaged position, the handle portion of the lever 3 is hooked under the keeper 22 in the manner shown in Figure 1. By disengaging the handle from the keeper it is obvious that the usual spring return (not shown) of the clutch mechanism will serve to move the clutch pedal from the disengaged position in full lines to the engaged position shown in dotted lines. The aforesaidpin and slot connection between the rocker arm 14 and the link 9 permits the necessary freedomof movement between the auxiliary operating device and the clutch pedal. In other words the presence of this pin and slot connection prevents interference of the back and forth movement of theclutch with the operating device. 1 1

Attention is invited to the fact that the hand grip 4 on the operating lever 3 is located at a point and at an elevation to permit it to be conveniently grasped by theoperator while Walking along behind the machine. It

will therefore be seen that thelever may be operated either while occupying the seat,

or by walking along on'the ground by the side:

ventionhas been shown and described, it is to be understood that minor changes coming within the field of invention claimed maybe resorted to if desired.

Having thus described my invention, whatv I claim as new is 1. In a structure of the class described, a rocker arm provided with clamps for connection to a clutch operating member, an upwardly extending lifting link disposed at substantial right angles to said arm and having pin and slot connection with said arm, an operating lever pivotally connected with said link, and a supporting and pivotal mounting bracket for said lever.

2. In a structure of the class described, a

rocker arm provided with clamps for connection to a clutch operating member, an upwardly extending lifting link disposed at substantial right angles to said arm and having pin and slot connection with said arm, an operating lever pivotally connected with said link, 7 a supporting and pivotal mounting bracket for said lever, together with a retainingdevice comprising a standard provided on one side with a part formed at its opposite ends to provide upper and lower keeper seats for an end portion of said lever.

3. In a structure of the class described, a machine attachment comprising a rocker arm having outwardly diverging clamps at its forward end adapted for connection with .the clutch operating pedal, a right angularly disposed. link, said link having pin and slot connection with an adjacent end of said arm, a supporting bracket embodying an upright having an offset portion, and an attaching part at its lower end, a horizontaloperating lever pivotally connected to the offset end of said upright and to the upper end of said link, said lever terminating in an. upturned end portion forming a handle, and a retaining device for said handleembodying a standard provided on one side with upper and lower keeper seats for selective reception of the handle portion of the lever.

In testimony whereof I aflix my signature.
