PEDAL FOR vELooiPEDEshf SPECIFICATION forming part of Letters Patent N o. 700,492, dated. May 20, 1902.

Application filed July 17, 1900.

T0 alwlwm, t may concern:

Be it known that I, EDWARD WiLLIAM II EN- STOCK, medical student, a subject of the Queen of Great Britain, residing at Drayton Villa, Lumley Road, Liverpool Road, Chester, in the county of Chester, England, have invented cert-ain new and useful Improvements in Pedals for Velocipedes, of which the following'is a specification.

This invention relates to velocipede-pedals capable of being foldedn p against or toward the pedal-crank when not required for use.

According to this invention that part. of the pedal on which the vfoot bears may be of the usual or anyv suitable construction and mounted with ball-bearings in the usual or any other suitable manner on-the pedal ,shaft or spindle, the inner end of which latter is a hingedor hinge-jointed to the outer end of 2O the pedal-crank, as hereinafter described, and capable of folding inward toward vthe crank, While the outward movement isA preventedbeyond a certain'point, as hereinafter described, a special locking device being provided to lock and irmly'lsecure the pedalshaft rigidly in position for useffi. e., at right angles to the crankthissame locking device also serving tohold the pedal in the folded position. v n

In the accompanying drawings, Figure 1 shows a crank and a pedal-shafthinged thereto according to the present invention, the pedal being arranged at right angles tothe crank in position for use'. Fig. 2 shows the pedal-shaft turned upon its hinges toward the crank. Fig. 3 shows the pedal folded up on its hinge and laid close against the crankthat is to say, in-position to which the same can be moved when o'ut of use. Figs. l to 7, inclusive, show a slightly-modified construction, in which Fig. 4 is a rear view, Fig. 5 a front view, Fig. 6 a side view, of the crank of the hinged pedal supposed' to be in position for use; and `Fig.- 7 is a similar view to Fig. 6, showing the position when the pedal is out of-use. p l

In carrying out the present invention the inner end of the pedal-shaft C may either be screwed into or otherwise secured to a boss or enlargement D or may be integral with said enlargement or boss D on its inner end,

this latter being hinged at E to the crank A serian. 23.924. no man.) v

latter. D outermost from the hinge-joint E is formed snugly and exactly in alongitudinal. slot or f1 recess A2, hereinafter referred to, and the second slot adapted to'rec'eive the same' and lof` cated in the onter'end A ofthe c'rankA at f an angle to the iirst slot II, liereinafterde-V scribed, when the pedalifs in its normal low;-

ered position, as in vFigQLand to'thereby limit the outward swing ofthe pedal-shaft C and at the same time assist in holding the. i

In this snug Fa slot G is provided inl a lineparallelwith the longitudina-l axisofthe hinge-pin'E, and

same rigidly in position for'use.

a corresponding or other suitable slot H is actly register and coin'cidetwhen the pedal is in position for use at right angles to the crank,

as shown in Figs. 1 and 6, respectively,where upon the locking device or bar I, hinged` at J, is inserted in Ythe said two slots G H, i i n Which slotsit exactly ts, and thereby retains' the pedal-shaft firmly and rigidly in position, thislocking-bar IA being hinged in the slotfH in the crank extremity A' and provided with a screw-threaded projection I on its freeend, on which a nut IX is screwed to lock and hold said bar I in the said tWo slots GH when the latter coincide. It is evident that the lock# ing device or bar I may bexed in position in any other suitable manner. f

When Ithe pedal is folded in the position shown in Fig. 3, it is locked and held in this position by replacing the bar I in the slot H, which thereby engages with the innermost extremity of the boss or-enlargement D--in i other Words, the end of the snugF.

The bar I shouldbe madefofthe'exact size and shape of the slots H G, so thatwvhen the pedal is in the position yshown inrFigs. l and 6 the end of the crankis practically solid and the weakening eect caused by the hinged pedal reduced to a minimum.

provided in the outer end A' oflthe "crank i A, these'slots G and H being adapted to ex- In Figs. 4 to 7 only a slight modification is shown-that is to say, the configuration, shape, or design of the adjacent portions of the crank and pedal-shaft is different from the other figures-the mechanical construcf tion, however, being the same asin the latter "and the details being somewhat clearer.

The essential feature of the present invenlion consists, therefore, in the special construction and fitting together of the pedalspindle end and the bifurcated crank end and the cross-cut formed bythe slot Gin the pedalspindle and the transverse slot H in the bifui-cated crank and the locking-bar I, adapted to fit accurately7 in said slots G H when in alineinent, and thus form a practically solid crank end.

Having thus described my invention, what I claim as new, and desire to secure ,by Letters Patent, is-

1. The combination, with a crank and a pedal-shaft pivoted to the outer end of the same, said crank having a longitudinal slot in its outer end and a second longitudinal slot at an angle to the first and in tie plane ofinovement of the pedal-shaft, of a snug projecting from said pedal-shaft and entering the said second slot, a slot in said snug registering with tho First-named slot ofthe crank when the shaft is in lowered position, a locking-bar pivoted at one end to one side of the crank and adapted to swing in the iirst slot across the second, a screw-threaded projection on the opposite end of the locking-bar,and means for connecting said projection with the crank, substantially as set forth.

2. The combination, with a crank and a pedal-shaft pivoted to the outer end of the same, said crank having a longitudinal slot in its outer end and a second longitudinal slot at an angle to t'he rst-and in the plane of movement of the pedal-shaft, of a snug projecting from said pedal-shaft and entering said second slot, a slot in said snug registering with the first-named slot of the crank when the shaft is in lowered position, a locking-bar pivoted at one end to one side of the crank and adapted to swing in the first slot across the second, a screw-threaded projection on the opposite end of the locking-bar and projecting beyond the side of the crank, and a lockingnnt on said projection, sub stantially as set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.
