PEDAL ATTACHMENT FOR eac er.

Specification of Letters Patent.

ST. PAUL, MINNESOTA.

ACCELEBATING-LEVERS.

Application filed May 22, 1916. Serial No. 99,043.

To (1Z5 whom it may concern:

Be it known that I, LnsLIE S. HACKNEY, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State ot' Minnesota, have invented new and useful Improvements in Pedal Attachments for Accelerating-Levers, of which the following is a specification.

My invention relates to improvements in pedal attachments for accelerating levers.

In automobiles andelsewhere, foot levers are usually provided to control the operation of motive-power. In using these levers, the driver places the sole of his shoe against a lever and. in operating said lever, tiltably supports his foot at the heel upon the foot board. This practice has two disadvantages, both of which impair uniformity of control. First, in attempting to hold his foot in the unnatural position described. the driver is fatigued and frequently inefficiently operates the pedal, especially when the vibration of the car is great, and secondly, owing to the frictional contact of the drivers shoe with the foot lever, difficulty is experienced in at tempting to uniformly actuate the lever.

The object of my present invention is to obviate these disadvantages and, generally, to provide a simple attachment for the ordinary accelerator levers having a support upon which a drivers foot may freely rest in a natural position and also to provide foot-operated means adapted to cooperate with a pedal, whereby tilting movements of the foot efiiciently and uniformly actuate said lever. 1

Other novel features of construction and combinations of parts will be more fully hereinafter described and pointed out in my claims.

In the drawings, Figure 1 is a perspective view of my improved device, showing the foot board of an automobile upon which said device is mounted andalso illustrating an ordinary accelerator lever which is operated by said device; Fig. 2 is a longitudinal central sectional view of my attachment; Fig. 3 is a sectional view taken on the line 33 of Fig. 2.

Referring to the drawings, 1 have used the reference letter A to indicate the pedal and ll the standard upon which said pedal is mounted. Said pedal A comprises a spoolshapcd toot rest 9 consisting of a hollow cylindrical body 10 having ends 11 enlarged to form annular keepers 12, and an exten- -turned upward at their ends.

19 have ahned perforations 20 therein. and

sion 13 widened at its end to form a solecontact 14:.

The standard B includes a flange 15 Patented J! an. 30, 19917.

adapted to be secured by screws 16 or the 5-.

like upon the foot board 17 and a post 18 rising from said flange 15 and supplied with a pair of oppositelv extending arms 19 These arms are inserted in an opening 21 at the bottom of the foot rest, which is formed by cutting away a portion of the cylindrical body 10. A pintle 22, axially secured in the ends 11 of the foot'rest 9, passes through the perforations 20 in the arms 19 and pivotally secures the pedal A upon the standard B. The upturned portions of the arms 19 fit snugly within the ends 11 of the foot rest and prevent sidewise movement of the pedal A, while the opening 21 in the body 10 permits a substantial tilting movement of said pedal without interference with the standard B.

Beneath the sole-piece 14 of the pedal A are two pendant cars 23 in which a roller 24 is revolubly mounted by means of a pintle 25 assing through said roller and ears. My attachment is so positioned upon the foot board 17 that the roller 2% rests upon the accelerator lever 26, as shown in Fig. 1. I employ a pad 27 of rubber, or other suitable frictional material, upon the sole-contact 14 of the foot lever. My attachment is easily applied to an automobile by simply securing the flange 15 upon the foot board thereof.

In use, the driver places his foot upon the foot rest 9, as illustrated in dotted lines in Fig. 2. the shank of his shoe resting upon the cylindrical body 10, between thev keepers 12 at the ends thereof. It will be readily seen that in such position the foot is freely and naturally supported. he sole of the drivers shoe extends over the sole-piece ll, which may be depressed by lilting the foot. In depressing the pedal, tlni roller fZ-l bears upon the lever 96 and. owing, to its rolling contact with said lever. causes the same to move uniformly with respect to the movement of the pedal. The usual resilient devices (not shown) which raise the lever 26, necessarily elevate the lever A when pressure is removed therefrom.

This device is particularly advantageous in that it lessens the strain upon the driver of an automobile and, owing to the evenness of control, promotes comfort in travel and avoids unnecessary wear andtear upon the machine.

Having described my invention, what I claim as new and-desire to protect by Let ters Patent, is:

1. In a device of the class described, the combination with a foot lever, of a pedal comprising a cylindrical foot rest having keepers at its ends and designed to receive the shank of a shoe and an oscillatory sole piece integral With said foot rest, a standard upon vhich said foot rest is axially pivoted and a roller mounted beneath said sole-piece adapted to rest freely in contact with said foot lever.

2. In a device of the class: described, the coml'iination with a foot lever. of a standard, a pedal comprising a foot rest designed to receive the shank of a shoe, and an oscillatory sole-piece integral with said foot rest, a pivot securing said foot rest upon said standard, said foot rest being designed so that the pressure thereon is transmitted radially to the pivot in said standard and a roller beneath the sole piece arranged to rest freely in contact with the lever and transmit motion from said pedal to said lever.

3. In a device of the class described, the combination with a foot lever, of a standard, a pedal comprising a hollow cylindrical foot rest having a portion of its annular wall cut away to receive the end of said standard, a pivot passing through said standard and axially arranged within said foot rest, and a sole-piece integral with said foot rest adapted to co-act with said foot lever.

4. In a device of the class described, the combination with a foot lever, of a standard having laterally extended arms turned upward at their ends, a pedal comprising a hollow cylindrical body having ends enlarged to form keepers at the extremities thereof, said body being .cut away to receive the arms, the upturned ends thereof fitting snugly within said ends of said body, a pivot mounted in said ends and passing through said arms, said pivot being axially arranged with respect to the cylindrical body, a solepiece integral with the body and a roller on said sole-piece arranged in rolling contact with said foot lever.

Whereof, Ihave hereunto subscribed my name to this specification.

LESLIE S. HACKNEY.
