EWALD F. PAWSAT AND HERMANN PAWSAT, OF SHEBOYGAN, WISCONSIN.

GRIPPER ATTACHMENT FOR PEDALS.

Specification of Letters Patent.

Patented May 24, 1910.

Application filed January 17, 1910. Serial No. 538,413.

To all 'whom it may concern:

Be it known that we, EWALD F. PAwsA'r and HERMANN PAwsA'r, citizens of the United States, and residents of Sheboygan, in the countyof Sheboygan and State of lVisconsin, have invented certain new and useful Improvements in Gripper Attachments for Pedals; and we do hereby declare that the following is a full, clear, and exact description thereof.

The object of our invention is to provide a simple and effective gripping-plate attachment for bicycle pedals, the invention consisting in certain peculiarities of construction and combination of parts as fully set forth hereinafter with reference to the accompanying drawings and subsequently claimed.

In the drawings Figure l represents a side elevation of a pedal provided with a gripping-plate embodying the features of our invention, parts of the same being broken away and in section to better illustrate its details of construction; Fig` 2, a transverse sectional view of the same as indicated by line 2 2 of Fig. l, and Fig. 3, an inverted plan view of the same.

Referring by characters to the drawings, l indicates a pedal pin upon which is loosely mounted the sleeve portion 2 of the pedal. The sleeve is provided with laterally eX- tending arms 3 for the support of a stirrupstrap 4, the same being of the rat-trap type and provided with upper and lower toothed edges cut away in scroll formation for the purpose of ornamentation and reduction in weight. This pedal is of standard type and forms no part of our invention, which invention primarily consists in providing means for attaching a corrugated gripping-plate to said pedal, the gripping-plate being adjusted over the toothed edges of the stirrupstrap with its corrugated surface exposed for the purpose of being engaged by the feet of the operator whereby liability of slipping is eliminated. The corrugated gripping surfacc is preferably composed of some pliable material suoli as rubber or analogous material reinforced by a metallic backing-plate.

Referring to the three iigures of the drawings, 5 indicates a flat metallic backing-plate, which plate bridges the space intermediate of the edges of the stirrup-strap l with its lower face arranged to rest upon the toothed edge of the same. The width of the tread portion of the backing-plate is the same as the width between the opposite edges of the stirrup-strap, the said tread portion being terminated with an abrupt right angle flange 6.l which flange is bent downwardly and overlaps the outer opposite faces of the stirrup-strap. Ears 7 extend downwardly from the central portion of the flanges7 the ears being formed with elongated slots 8, which slots are arranged to coincide with apertures 9 forming part of the scroll design of the stirrup-strap. The ears 7 with their elongated slots, together with the apertures 9 in the scroll design of the stirrup-strap thus form a convenient and simple means whereby the gripping-plate may be securely and quicklyT attached to a pedal of standard design. A single bolt 10 is utilized for securing these parts together, which bolt is provided with an intermediate offset portion 11 whereby said bolt when adjusted to position is cleared from the sleeve portion 2 of the pedal. The offset portion ll is parallel to the head and shank portion of the bolt, being connected thereto by oblique bolt sections l2 as best shown in F 2. Owing to the fact that the sections l2 are disposed obliquely with relation to the remainder of the bolt the same may readily be inserted through the respective elongated slots of the ears 7 and apertures 9 of the stirrup -strap, the peculiar formation rendering it possible to pass said bolts through these various slots and apertures and over the sleeve 2.

One end of the bolt 10 is threaded for the reception of a nut 13 and after insertion of the bolt in its position thereon said nut is run upon the screw threaded end to securely bind the parts together.

By referring to Fig. 2 of the drawing it will be seen that when the bolt and various parts are assembled the oset portion 11 of said bolt passes between the grippingplate and the sleeve 2 and thus renders the device sightly as well as to insure the bolt being retained in position even though the clamping nut should become detached. This is due to the fact that when the user exerts pressure vupon the gripping-plate, the latter is sufficiently resilient to permit a slight sag, whereby the offset portion 1l of the bolt 1s gripped between said gripping-plate and sleeve.

A sheet 14, preferably of corrugated rubber, is secured to the tread portion of the backing-strip 5 by means of rivets l5, the

more, in practice it has been found that by grooving or Hanging the backing-strip the number of operations for completing the device is increased, thus proportionately ink creasing the cost in manufacture and at the Ysaine time these grooves or flanges tend to crystallize the metal and thereby weaken the strength of the same to the detriment of its Wearing qualities. By simply utilizing a fiat, unbroken surface for the tread portion of the backing-strip in connection With a single longitudinal bend at its edges as shown, the above objectionable features of construction have thus been eliminated.

vWe claim:

1. In a bicycle pedal having a scroll stirrup-strap; the combination of a gripping attachment comprising' a continuous backing-plate having an unbroken flat tread portion, right angle flanged portions extending from the backing-plate and adapted to overlap the stirrup-strap, slotted ears extending from the flanges, the slots being arranged to coincide With apertures of the `scrolled stirrup-strap, and a securing bolt for the gripping attachment, the securing bolt being arranged to pass through the slotted apertures of the ears and scroll apertures of the stirrup-strap aforesaid.

2. In a bicycle pedal having a scroll stirrup-strap; the combination of a gripping attachment comprising a continuous backing-plate having an unbroken tread portion, right angle flanges extending from the backing-plate adapted to overlap the stirrupstrap, slotted ears extending from the flanges and means for securing the slotted ears to said stirrup-strap.

8. In a bicycle pedal having'aV scroll stirrup-strap;Y the combination of a gripping attachment comprising a backing-plate having apertured flanged extensions adapted to engage the stirrup-strap, a corrugated sheet secured to the backing-plate and a securing bolt for the backing-plate, the securing bolt being provided With an intermediate oset portion.

4. In a bicycle pedal having a central sleeve and apertured stirrup-strap; a gripping attachment for the pedal comprising a backing-strip having apertured flanges adapted to straddle the stirrup-strap, a corrugated sheet secured to the backing-plate and a securing bolt for the gripping attachment arranged to pass through the flanged apertures and stirrup apertures, the bolt being provided With an intermediate oset portion disposed to one side of the pedal sleeve, the oset portion being connected by oblique sections to the head and shank portions of said bolt.

In testimony that We claim the foregoing We have hereunto set our hands at Sheboygan in the county of Sheboygan andState of Visconsin in the presence of tvvo Witnesses.
