SAMUEL H. LAW, OF BROOKLYN, NEW YORK, ASSIGNOR OF ONE-HALF TO HENRY PENNIE, OF SAME PLACE.

PEDAL ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 562,546, dated June 23, 1896.

Application filed January 18, 1896. Serial No. 576,051. (No model.)

To 6022 whom it may concern.-

Be it known that I, SAMUEL H. LAW, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful. Improvements in Pedal Attachments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in bicycle-pedal attachments, and has for its object to prevent the foot from slipping forward upon the pedal and to hold it in proper position thereon, so that the power exerted may be utilized to the greatest advantage.

In the accompanying drawings, Figure 1 represents in perspective a rat-trap pedal provided with my attachment. Fig. 2 represents in full lines a sectional view of the same in its relation to the foot of the rider and in dotted lines shows its normal position. Fig. 3 represents a sectional view of a rubber-tread pedal provided with my attachment; and Fig. 4 represents a top plan view, the position of the rubber being indicated in dotted lines.

Similar letters of reference indicate similar parts throughout the several views.

Referring to Figs. 1 and 2 of the drawings, A indicates a bicycle-pedal of the familiar rattrap pattern, having the customary cross-bars l) b. To one of these cross-bars I secure the attachment constituting the subject-matter of this invention, consisting of stout wire, bent in the general form of ayoke,havin g arms 0 and cross-piece d and so formed as to have a number of spring turns a, these elements constituting the generic or characteristic features of the improvement, and being likewise present in the construction shown in Figs. 3 and 4:.

To connect the attachment to the pedal, I may bend the free ends beyond the springs a, so as to form eyes e,through which. pass screw-bolts f, extending through holes bored in the crossbar b, and provided beyond said cross-bar with washer plate 9 and nuts h; or, preferably, I may screw-thread the ends of the wire themselves and secure them to the pedal,

lines in Fig. 2,

by means of like nuts Z, as indicated in Figs. 3

and 4, which show such threaded ends extending through the rubber m, immediately above the bearing-pin upon which the rubber is mounted.

If desired, I may provide the cross-piece cl with a freely-revoluble sleeve d, having a number of pointed stud projections, as shown suiiicient to hold the shoe against undue side movement, but which at once become disengaged from the heel should the rider fall from the machine.

In its normal position the pedal hangs from the axle in the manner indicated in dotted so that when the rider has mounted the machine his foot can at once bring the pedal to the proper position, (shown in full lines in that figure,) thereby bringing the ball of the foot directly above the central part of the pedal, and so that the heel of the shoe is brought into contact with the rear portion of the attachment. The attachment therefore constitutes what may properly be termed a gage for the foot, automatically determining its position on the pedal, giving it a long bearing and utilizing the pressure of the heel.

Prominent among the advantages of the construction, in addition to its durability, lightness, and ease of manufacture, are that it is impossible for the foot of the rider to be caught and held should an accident throwhim from the machine; that the pedal is always in position to be properly found by the foot and correctly adjusted thereto; and that the spiral springs a yield to the pressure of the foot, thereby permitting it to rest firmly upon the pedal when power is being exerted, and yet giving to the rider, during the rise of the pedal, an easy spring-bearing thereon.

It will be apparent that the attachment can be attached to either cross-bar b or b, or to either rubber m or m, as occasion may require, the change being readily eifected. Should the machine be temporarily used by a rider to whose shoe the attachment is not adapted, the pedal may be simply turned end for end and thus used by him without the nec'essity of removing the attachment for that purpose.

Having thus described my invention, what I claim is 1. A bicycle-pedal having attached thereto a foot-gage, consisting of Wire bent to form a yoke adapted to engage with the heel of the riders shoe, and twisted near its ends to form. spiral springs, said springs extending transverse to the arms of the yoke and provided with means for attachment to the pedal; substantially as described.

2. A bicycle-pedal having attached thereto a foot-gage, consisting of Wire bent to form a yoke adapted to engage with the riders shoe, and twisted near its ends to form spiral springs, said springs extending transverse to SAMUEL H. LAW. \Vitnesses:

JOHN SMITH, H. S. DUNN.
