HARVEY "WEBB PEACE, O33 TGEONTO, ONTARIO, CANADA, ASSIGNOR OF ONE-HALF TO JOHN "WALKER GIBSON, (3F TORONTO, CANADA.

PEDAL.

Application filed. Gctoher 4, 19:20. Serial No. 414,698.

To all whom it may concern:

Be it known that I, HARVEY WEBB Pnnon. a subject of the King of Great Britain, and resident of the city of Toronto county of York, Province of Ontario. in the Dominion of Canada, have invented certain new and useful Improvements in Pedals, as described in the follou-"ing specification and illustrated in the accompanying drawings. that form part of the same.

The principal objects of this invention are. to reduce the cost of production by minimizing the labour of construction, and to produce a pedal of extremely fine appearance and which will very strong and durable.

The principal feature of the invention consists in the novel construction of the pedal frame in a unitary moulded structure and in the novel formation of the longitudinal side members of said frame whereby the pedal rubbers are supported and secured.

In the drawings, Figure 1 is a perspective view of my improved pedal showing one of the rubbers partly broken away.

Figure 2 is a plan view of the pedal in part horizontal mid section.

Figure 3 is a cross sectional view of the pedal.

In the manufacture of bicycle pedals it has been the practice to construct the pedal barrel, end. members and outer frame in separate parts which are fastened togetherin various difierent ways. Such method of construction involves a great number of opera tions in making the various parts and in assembling and the pedal when completed. is comparatively fragile and the parts become loose in a very short time. It is the purpose of this invention to eliminate the costly form of construction and material and to form the entire pedal frame of one piece, cast in aluminum alloy.

The structure comprises the barrel 1 which is cast with a longitudinal central opening 2 formed at each end with the cupped portions 3 into which the ball shells 4. are pressed.

The end plates 5 are cast integral with the cupped portions 3 and horizontal webs 6 reinforce the end plates, extending out from the barrel portion and uniting with the longitudinal side bars 7. The side bars are preferably connected with the barrel portion midway of their length by the webs 8.

The side bars are preferably formed substantially T shape in cross section, the head 9 of the T being arranged at right angles to the

webs

6 and 8. The inward side of one or both of the projecting flanges of the head of the side bars is preferably under cut to form an inwardly extending angular flange 10 for the purpose of gripping and holding the rubber. In the drawing, Figure 3, only the one flange is thus formed on each bar as the forward pushing pressure of the foot only acts against one of the rubbers to dislodge it. The rubbers 11 are of any desirable pattern moulded in a rectangular cross sectional form having a longitudinal hole corresponding in cross section with the shape of the side bars 7 and on the inward sides the rubbers are split longitudinally from end to end, the edges of the split portion meeting or abutting the horizontal webs where said webs pass through. The rubbers may be very easily sprung into place. They will securely grip the side bars without the necessity of any other form of fastening but it will be understood that bolts, screws or any other form of fastening means may be utilized if desired.

The outer end of the main pedal frame is preferably formed with a projecting flange 12 surrounding the cupped recess and a cap 13 also formed of cast aluminum is formed with a corresponding internal recess to fit the flange 12 which cap is secured in position by the screws '14- which enter the suitably threaded holes in the end plates.

The pedal spindle is of the usual form and it will be readily understood that a pedal structure such as described may be die cast in a very accurate form and will require no machining or even polishing. The ball shells can be pressed into the moulded seats and it will be merely necessary to tap the holes for the screws 14. If desired the 6X- posed surfaces of the metal may be burnished in order to brighten their surfaces.

The pedal rubbers are placed in position by simply spreading the split side open and forcing it over the longitudinal side bars and when in position they will grip the side bars securely. The saving of labour and expensive materials by the adoption of this form of pedal will be readily apparent.

What I claim as my invention is 1. A bicycle pedal, comprising. a unitary casting of aluminum formed with a central barrel portion to receive the spindle and havhaving laterally extending radial Webs and end plates east integral therewith, said Webs being slotted from end to end, and rubbers slotted longitudinally and adapted to be inserted into the slots in said Webs and to overlap and interlock with said Webs.
