Application iiled February 10, 1902. Serial No. 93,432. (Nomdel.)

To cir/ZZ whom it may concern:

Be it known thatI, JOSEPH AUGUSTE DE- OUIR, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have made certain new and useful Improvements in Bicycle-Pedals, of w, ich the following is a specification.

T le object oi` my invention is to produce a bicycle-pedal having maximum lightness,

strength, durability, and c heapness.

`the frame proper of tubular guards,which are adapted to retain their `place upon the toothed portions of the frame bymeans of their own elasticity, butwhich maybe readf ily removed as occasion requires.

rIhe details of construction,arrangement,`

and operation are as hereinafter described, reference being had to accompanying drawings, in Which i i Figure 1 is a face view of my improved pedalapplied to the spindle of a bicyclecrank.` Fig. 2 isa transverse section on the line 22 of Figpl.` Fig. Sis a perspective viewof one of the foot frame-sections or footholds. Fig. -t is a perspective View of one of "same being represented in the flat. a detail section illustrating the anti'frictione bearing ot' one of the hubs with the spindle.

the hubs to which the frame-sections or footholds are attached; one of the framesections Or footholds, the Fig. 6 is The pedal-fraine is made up of three metal Sections or subsidiary frames A, the same being riveted together, as shown. Each of these framesections A has primarily the form represented in Fig. -that is to say, each is a quadrilateral, it being an oblong rectangle,

and is formed by cutting it ont of sheet metal by means of dies. It may, however, be formed iu any other manner. The side bars l are Fig. 5 is a face view of' at right angles to the side bars l, and in practice they constitute the side guards for the pedal, which serve to retain the foot oi." the rider in place as to lateral movement. The entire body ofthe 'end bars 2 is practically turned at right angles to the side bars l to adapt them for insertion in slots 3, formed in the angles of the triangular hubs 4, as shown in Fig. 2. In brief. the end bars2 are twisted so that their middle portions lie practically at a right angle to the side bars l. 'lhe side bars 2 of the toothed frames A are cutout or curved on the outer side at the middle Ot' their length, as shown in Fig. 5, and such curved or cut-out portion fits in the slots 3 of Vthe hubs 4, so that the frame-sections are thus held more Iirmlyin place than would be practical if the outer edges lOi" the said bars were straight. The toothed edges of the frame-sections A are bent Outward, the angie-being formed a little below the teeth, as shown at 6, Figs. 2 and 3, so that when the bars l of adjacent frames are riveted together they lie in contact, while their toothed edges 6 diverge at an obtuse angle, as required to produce a rin foothold. When the three frame-sections are applied to the triangular hubs 4, as shown, and riveted together, they constitute a triangular frame, whichis held immovable with` relation to the hubs, and therefore revolves with the latterupon the spindle 7 of the bicycle-crank. Each of the two hllbs 4 has an `antifrictionfbearing, as shown in Fig. The frame-sectionsA are providedwith two holes in each of the side bars l and a hole at each angle, as shown in Figs. 2, 3, and 5, for receiving the rivets by which the sections are secured rigidly together. It will be seen that this frame has maxim um lightness,strength,and rigidityand "in ay be produced at very small cost.

I provide for the several toothed or`ser rated footholds 6 an. elastic guard 8, which is adapted to retain its place by its own elasticity, but may be readily detached when required. Each guard 8 is formed of asection of rubber tubing of due thickness, the same being slotted lengthwise, so that it can be opened and clamped ou the serrated portion of foot-rest bar, and When in due position, as shown in Fig. l, it retains its place byits own elasticity, which causes it to clamp the in# IOO . or slots and three quadrilateral frame-sec' `reluded portions 6 with considerable firmness.

- `l. The improved triangular pedal-frame comprising two hubs and three quadrilateral sections formed of'th in plate metal, the plane of the end bars of said sections being at a right angle to that of the lside bars and engaged with the hubs, and. the side bars being secured together atwise and their edges forming footholds, as shown and described.

2'. .The improved triangular pedal-frame, formed of hubs provided With peripheral slits tions formed of sheet-steel, the end bars of the same being turned ata right angle to the side bars and inserted in the slots ofthe hubs, and the side bars being riveted together, sub-- stantially as shown and described.

3. vThe improved bicycle-pedal frame, comprising triangular hubs having radial slits at their angles and three frame-sections formed of sheet-steel, the end bars of the same being curved or cut out ony the outer side, at the middle of their length, and bent at a right dle oftheir length, at a right angle to the side bars, and their outer edges inserted in lthe slits of the hubs, the said side bars lying in contact and being serrated and bent o utward at their edges to form footholds, substantially as shown and described.

5. The combination, with a pedal-frame, having daring toothed edges constituting footholds, of a guard consisting of an elastic tube slitted lengthwise whereby the tube is adapted to be clamped on such toothed portions, amd to clamp the same by its own elasticity and thus retain its position in use, substantially as shown and described.
