CONTROLLING MECHANISM FOR MOTOR-VEHICLES.

Specification of Letters Patent.

Patented July 17, 1906.

Application filed July 20, 1905. Serial No. 270,461.

To all whom it may con cern:

Be it known that I, CHARLES O. SNYDER, a citizen of the United States, residing at the city of New York, in the borough of Manployed in practice is to have a plurality of pedals connected, respectively, to the brake mechanism, to the low and to the high speed clutches, so that the motive ower of the vehicle is entirely controllable by the feet of the operator, leaving his hands free for steering. Additional means for setting the brake, such as a hand-lever, is, however, generally provided, because in an emergency the brake should be operated in the most direct and positive way and with a high leverag and power.

With the above arrangement a difficulty sometimes arises in practice on account of the tendency of the chauffeur when confused or hurried to forget to release the holding pawl of one of the pedals when another is depressed, so that it may happen that the brake and one of the clutches is in o eration at the same time, or both of the c utches, which would be likely to damage the mechanism.

It is the purpose .of my invention to devise a structure by which the holding-p awl of any depressed pedal is released when any other pedal of the controlling series is depressed.

A further object of my invention is to provide ahand-brake which will serve to release all of the pedals whenever it is applied.

A further object of my invention is to devise a construction which is simple and easy to construct, eflicient in operation, and havin a minimum number of arts.

, INith these and other 0 jects in view my invention consists in the construction, combination, location, and arrangement of parts,

all as will be more fully hereinafter set forth, as shown in the accompanying drawings, and finally particularly pointed out in the appended claims.

Figure 1 is a perspective view showing a series of foot-pedals having a construction embodying the principles of my invention and also showing diagrammatically the various devices which they respectively operate. Fig. 2 is a detail side elevation of one of the pedals, showing it in its normal and in its depressed position.

Referring now to the drawings, and to the views and reference-signs appearing thereon, wherein the same signs designate like parts wherever they occur, 1, 1 and 1 denote pedal arms or levers journaled to a fixed portion of the frame at 2, 2 and 2 and having heads or pads 3, 3 and 3 thereon. I prefer to construct each of the pedals in substantially the same way, and I have shown a con venient form of construction for this purpose which is particularly illustrated in Fig. 2. In this figure the head 3 is pivoted to the arm 1 at 4.- and has attached thereto a de ending link 5, which is connected to a paw 6, pivoted at 7 on the arm 1. 8 denotes a stationary fixture upon the frame of the machine, which has an upper surface concentric with the pivot 2 and an end wall or shoulder behind which the pawl 6 is ada ted to dro when the pedal 3 has been fully de resse By this means the pedal is locked an held in its depressed position until it is released by the action of the operator, who moves his foot to turn the head 3 and raise the pawl 6, after which any suitable spring (not shown) becomes efiective to return the pedal to its normal position. Such normal position is illustrated by the dotted lines in Fig. 2, the full lines illustrating the depressed position thereof. The mechanism thus far described is of the ordinary and well-known construction and forms no part of my present invention.

Journaled within any stationary art of the frame and preferabl within the tures 8 I have arranged a roc shaft 9, which extends across the entire series of pedals and has cam- arms 10, 10, and 10 secured thereto. These cam-arms are adapted to lie in the ath of a toe or projection 6 upon each of t e pawls 6. While I have arranged the cam 10 to act directly upon the pawls in this way, it is obvious that any intermediate connection may be made in lieu thereof and still fall within the principles and scope of my invention.

1 1, 11 and 11 indicate pins upon each of the pedal-arms1,"1 and 1 which are'disposed beneath the cam- arms 10, and 10 so as to contact therewith, and these cams are formed with inclined surfaces upon their lower sides to cooperate with the pins and be raised thereby when any pedal is depressed.

A convenient form of cam, which I have adopted in practice, is illustrated in Fig. 2, and comprises an initial lower surface 12, an incline 13, and a second reverse incline 14, culminating in a flat portion 15. 16 shows a projection on the upper surface of each camarm, which is adapted to lie directly beneath the toe 6 of each pawl 6 when the pedal carrying that pawl has been depressed,

For the purpose of rendering my invention more easily understood I have made a diagrammatic showing of the high and low speed clutches and the brake mechanism of an automobile, of which (referring to Fig. 1) A denotes the high or first speed clutch, and B the second or low speed clutch, while C indicates the usual brake mechanism, which may include reversing means for the vehicle as well. It is to be distinctly understood that these parts, as shown in Fig. 1 of the drawings, are of purely diagrammatic representation, their construction and disposition in an actual machine being varied to satisfy the conditions and taste of any particular designer. It is merely essential for the purpose of my invention that some sort of connection be provided between such devices and the operating levers or pedals. Also in diagram matic representation is the hand-brake lever D, which is connected to the brake C through any sort of slotted link connection 17. Attached at some point on the hand-brake mechanism D, I arrange a link 19, having a slotted end engaginga pin 20 upon an arm 21, extending from the rock-shaft 9. The arm 21 may, if desired, be integral with the cam-arm 10 18, 18, and 18 indicate links which are respectively connected to the arms 1, 1, and 1 and extend in any suitable or desired manner to the clutches B A and the brake C, or other mechanism, if necessary.

The operation of my device will be understood from the preceding description. Any pedal having been depressed is locked in such relation by its pawl 6?. When now another pedal-as, for example, the pedal 3 is depressed, the pin 11 slides along the lower surface of the cam-arm 10 and coming in contact with the inclined surface 13 raises the cam-arm and with it turns the rock-shaft 9. This is effective to rock all of the other camarms 10 and 10, and should any pedal of the series happen to be already de ressed the projection 16 will contact with t e toe b of such pedal and lift it out of engagement with Y its fixture 8, whereupon the pedal will be returned to normal position by its usual spring. (Not shown.) It is apparent that whatever pedal is depressed all of the rest will be returned by the action of the rock shaft 9. In any case the pin 11 of the pedal which is being operated finally drops behind the incline 14 onto the flat surface 15 of the corresponding cam, whereupon its pawl 6 is not further disturbed and is effectiveto hold that pedal depressed. When the foot-pedal 3 is depressed, the brake is operated through the connection 18 and the hand-lever D remains idle by virtue of the slotted link connection 17. When the hand-lever D is op erated, the link 19 is thrust forward and engaging the pin 20 rocks all of the cam-arms upward, releasing all of the foot-pedals. The slotted link connection 19 permits the normal operation of the pedals, however, when it is desired not to manipulate the handle D.
