JOHN E. STRIETELMEIER, OF CINCINNATI, OHIO, ASSIGNOR TO THE IDEAL WHEEL COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO.

SPRING-WHEEL.

Application filed November 3. 1913.

To all whom it may concern:

Be it known that I, J 011x E. SrnIE'rEL- MEIER, a citizen of the Unitedstates, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Spring-VVhe'els, of which the following is a specification.

This invention deals with a resilient wheel and it is exemplified in several of its embodiments by drawings in which Figures 1, 2, 3, 1 and 5, show a sectional. side elevation, a

radial section, and perspectives of a spoke element, a hub-wedge-block, and a hub-boltcover, respectively, all of one embodiment in which sockets are swaged in the felly-band and the clamping member is devoid of sideflanges. Figs. 6 and 7 are circumferential and transverse sections of a modification having similar characteristics. Figs. 8, 8 and 9 show a fiangeless clamping member and a socket-block secured to a rim element. Figs. 10, 11, 12 and 13 show a rim element recessed to receive a socket-block and illustrates the details of this construction which proposes the use of a clamping member having flanged sides. Figs. 14:, 15, 16 and 17 are views of a similar construction using flanged clampingmembers, but another type of socket block. Figs. 18 and 19 are a side elevation, )artly in section, and a radial sec tion, respectively, of a portion of the wheel, on a larger scale.

The spokes of the wheel emerge from the hub in loop-like form, and each loop-like spoke consists of two flat-metal spoke- elements 3, 3, which are curved as shown to augment their normal resiliency and which both converge toward the rim and are both sesured thereto by a single fastening arrangement which in its relation to the spoke-elements is more especially the subject of this application. The construction at the hub need not here be elaboratedas it is described and claimed in my copending application, No. 720,521, filed Sept. 1.6, 1912.

-This invention proposes a rim construction providing an equispaced series of sockets of either the open-side type 11 or the closedside type 11*, and which are adapted snugly to receive the flanged ends or feet'12 of the spoke elements, all in coacting relation with a clamping member, and a draw-up leverage device for adjustably forcing the clamp- Specification of Letters Patent.

-clamp said spring-feet by pressure in the same.

The inner ring or felly-band of the rim may be an annular U-shaped channel piece 10 in which the sockets 11, are indented at regular intervals in a radial direction, in this instance preserving the side-walls substantially in parallelism, but having the end walls 1 inclined at an angle to a radius to converge somewhat toward the bottom 2, so as to permit the spoke elements to-enter the sockets at an angle to the radius. This bottom 2 extends in a circumferential or tangential direction, and as shown by Figs. 1,2, 6 and 7. the bottom 2 of the socket indented in the felly-band 10 receives support from the felly proper (7) whereby it is braced against movement under the strains of the flexible spokes. This socket support may assume various forms. Thus, as indicated by Figs. 1 and 2, a filler-block 1 of wood or metal may intervene between the bottom 2 of the socket and the adjacent face of the felly proper, or, as shown by Figs. 6 and 7, a counterpart pocket 9 may be formed in the felly-proper 7 and its bottom 5 may be in flatwise contact with the bottom 2 of the spokesocket so as to support the same. These pockets 9 may be formed at the inner periph eral face of the folly proper and this inner face or portion may extend in the form of a circumferential rib 6 of greater or lesser size or proportions, as indicated by Fig. 6. These pockets 9 may be very advantageously also utilized to contain the squared enlarged head of a bolt, as shown by Fig. 6, or these pocket-s may be given the form of conical apertures 9 shown by Fig. 1 and adapted to receive the conically upset ends of the bolts.

The spoke receiving sockets may also be provided by separate blocks secured to the inner periphery of the rim. The socketblock may be simple U-shaped form as indicated by 15 in Fig. 16 having open sides and end walls 17 providing converging inner spring-supporting faces 18 and mounted directly upon the rim-member and positioned as by pins 19. Or the socket-block may be of the straddle or saddle type shown by Fig. 13 or Fig. 10. In the case of the saddlesocket-block 20, the inner felly band 10 may be of wood suitably mortised at intervals to receive the saddle block and bring the side flanges Qlthereof in flush relation with the 7 Preferably the end walls 2% and 26 of these blocks will provide inclined inner faces as before described. 7

' While the clamping member proposed by this invention may take various more or less modified forms, it in all instances is constructed and arranged'to exercise true clamping functions. That is to say, this clamping member is positively and forcibly driven in a radial or spring-gripping direction by means of an appropriate cooperat ing element, so as variably to increase the pressure on the spring-ends to create sufficient friction to prevent relativemovement between the parts. In the forms shown by Figs. 10, 11, 12, 1d, 15 and 16, the clamping member is U-shaped and has side flanges that close the open-sides of the sockets with which they interfit, whereas in the other illustrated forms, it has the more elementary form of a simple bar.

Thus, as shown in Figs. 1, 2,, 6, 7, 8 and 9 the clamping bar 13 is a member having a central axial perforation 27 adapted to receive the shank of the bolt for the drawup nut and having its ends 28 inclined in parallelism with the end walls of the socket. Preferably when seated in its normal clamping relation, it snugly fits between the side walls of the socket, and its ends fall somewhat short of the end walls of the socket so as to leave room for the clamped intervening spoke elements.

The clampingemember 13" shown in Figs. 12 and 17 is for use with the sockets having the open sides and it provides side flanges llwhich normally close thoseopen sides. Its inclined clamping ends 29 and 30 respectively cooperate with the inclined endwalls 18 and 26 of the respective socketblocks,'in the same relation as described in the above-paragraph. It is to be noted that the side flanges 1 1- of this invention in all forms of. the clamping member fall short of any edge-abutment with any part of the rim, so that such member will have a mounting permitting of radially outward adjustment or movement thereby enabling itto exercise clamping functions on the spring elements, as distinguished from an inert clip or clevis having but a single posi tion and having its flanges in end-edge abutment with the felly or other part in such a way as to preclude a radially outward movement. Thus, the edge 31 of the flange 14in Fig. 10 is spaced somewhat away from the adjacent shoulder 32 on the socket block 20 when'the parts are normally assembled so as to enable a clamping movement to take place. So also, the edge 33 of the clamping member in Figs. 14: and 15-is normally interspaced from the adjacent portion 34: of the felly. This is of great importance, as otherwise the part 13' could not be brought into real clamping relations with the springs and the construcion' would be ineffective frictionally to hold and bind the springs against relative movement.

The springs elements 3 enter the sockets aforesaid andextend along and in fiat-wise contact with the inclined face of the end walls thereof, and then they follow a bend at an obtuse angle and extend half-way across the bottoms of the sockets in the form of end flanges or feet 12. As shown by Figs. 8, 10, 14: and 18, the extreme endedges are in edge-to-edge contact so as mutually to lock one another from twisting or like displacement movements.

To enable a leverage action to be exerted so as to force the clamping members against the springs, bolts 35 or 36 extend radially from a head-mounting on a rim element and pass through an aperturein the bottem of the socket, through the matching half- H apertures or recesses 3r in the ed es 01 the spring feet, and then they project through apertures 27 in the clamping member. Nuts 38 screw-threaded to the projecting portions of the bolts enable pressures to be forcibly applied in a radially-outward direction to cause said clamping members to be adjustably urged into positive clamping relation with the springs 3. It may be noted that bolts 35 hold the socket blocks place at the same time.
