Application tiledduly 9, 1890, Serial No.358,157. (No model.) i

Be it known that we, WILLIAM HIBBERT and ALFRED MANUEL, citizens ot the United States, residing at \Vilmington,in the county of New Castle and State ot Delaware, have invented a new and useful Bicycle, ot' which the following is a-speciication.

This invention relates to velocipedes, and more particularly to that class known as 1o rear-d riving Safety bicycles, and the object thereof is to eitect improvements in the construction and relative arrangement of 'the several component parts of a rnachinelot` this character, all as hereinafter more fully exi 5 plained, and as illustrated in the drmvings, in

which- Figure 1 is a general side elevation of our bicycle complete with saddle. Fig. 2 is a centrallongitudinal section of the head and front 2o fork. Fig. 3 is a transverse section through the front pair of rods of said fork. Fig. 4 is an enlarged detail of t-he connection between the lower ends of said rods and the front aXle. Fig. 5 is a side elevation of the frame with the spring-connection in section. Figs. 6 and are transverse sectionsvof the front and rear members of the frame, respectively. Fig. S is a plan of the rear frame member with the rear bearing in section. Fig. 9 is atransverse section through the propelling-shaft hanger, driving-sprocket,and cranks. Fig. v10 is a perspective detailof one of the cranks. Fig. 11 is a plan of one of the treadles. Fig. 12 is a side elevation,and Fig. 13 a centralvertical section, of the seat-supporting tube.

In the said drawings is shown our improved bicycle supported upon wheels 1V.

m and M are the front and rear members ofthe frame, respectively, connected by the 4o spring-connection C.

F is the front fork depending from the head Il, which latter carries the brake B, and R is the rea-r brace-fork connecting the rear bearings with the upper end of lthe seat-tube T,

carrying J[he saddle S. The Whole is propelled by the shaft and sprocket driven by cranks, constituting the propelling devices P. These several parts will now be explained in detail.

lVheels of any ordinary or preferred construction may be used so long as they are rof the machine; but on the hub 1 of the rear wheel are formed lugs 2, adapted to engage. notches 3 in the hub of a small sprocket- -wheel 4, traveling inside the rear fork and over this sprocket-Wheel travels a chain o, by which the machine is driven in a manner common in bicycles of this character. The 6o hub of the front wheel 6 turns upon an axle 10, whose ends pass through plates 11 at each side of the wheel and are held therein by wedge-shaped pins 12; or, if preferred, the shaft 10 may be fast in the front wheel 6 and 65 may turn in the plates 11 without departing from the spirit of my invention. Ball or cone bearings may be provided,also, without effecting material alterations in this device.

Pivoted at 13 in the front and rear ends of 7o each plate 11 are rods 14, formingan important part of the front fork F. Theserods extend upwardly and have heads 15 at their upper ends, which slide freely up and down Within sockets 1G, having reduced lower ends 75 17, whereby the heads 15 cannot slip therefrom. The upper ends of the sockets are closed and provided with reduced screwthreaded extensions 18, which pass through threaded holes in the ends of cross-bars 19, 8o and said bars are secured at their centers to the front and rear ends of a curved arm 20.

Between the heads 15 ot the rods 14 and the closed upper ends of the sockets 16 coiled expansive springs 2l areinte1posed,\vl1ereby 85 the front wheel 6 is cushioned against jars, as in passing over stones or through gulleys on the road.

The curved arm 2O has an integral upward extension 22 rising from its center, which eX- 9o tension passes through the front end of. the frame nicniberm, and to the upper side of said member is secured the lower end of a sleeve 23 by countersunk screws 24, as shown in Fig. 2. The extensions 22 may have a 95 shoulder 25, if desired, and this shoulder and thelower face of the member 'm may be grooved for the reception of balls, thereby forming a balled head. Said sleeve 23 may be also braced by a diagonal brace 26 between the roo member m and the sleeve, connected at its ends by screws or otherwise; butthis brace is not essential. On the extension 22 is aco-llar 27, having a lower end, which lits loosely over the upper end of the sleeve 23, and above said collar is a ring 28, secured to the extension by a set-screw 29, whereby the collar is held against the upper end of the sleeve, but. may be adjusted closer to take up wear between the parts. Above the ring 2S the extension is jointed on a' transverse pin 3G, for a purpose to appear hereinafter. These dcvices constitute the head H of our improved bicycle. The upper end of the extension 22 is t-hreaded, as shown, and screwed onto this threaded end is a block 30, having a hole therethrough for the handle-bar 31 and a setscrew 32 for holding said bar in place.

33 is the brake-lever, pivoted between its ends, as at 34, to the upper side of the handlebar and provided at its outer end with the turned-up lever-handle 35, whereby the rider mayoperate the brake from the top'of the handle-bar instead of from the bottom or rear side, as heretofore.

The brake B of this machine com prises the brake-shoe 40 at the front end of the brakearm 41, which is pivoted between its ends on a bifurcated lug 42 at the front end of the curved arm 20. The rear end of this brakearm is bifurcated, and pivoted thereto is a rod 43,having a threaded upper end 44. Another rod 43 is pivoted to theinner end of the brake-lever 33, and is also screw-threaded, as at 44. A turn-buckle 45 connects the two threaded inner ends of these rods, and when this buckle is turned the brake-shoe will be adjusted with respect to the front wheel, as will be understood. Said shoe is held normally off the wheel by contract-ile sprin g 4G between the inner end of the brake-arm 4l and the curved arm 20.

The frame of this machine comprises a front member m and a rear member M, pivoted. together, as at 50, the front member being of the cross-section shown in Fig. 6, and

the rear as in Fig. 7, although considerable departure may be made from this exact construction, ifv desired. The front lnember is connected to and supported by the front fork in a manner just described, and the rear member is supported by the rear wheel, as hereinafter set forth. These two members are joined by the spring-connection C, which comprises the following parts: 51 is a rod pivoted at its lower endto a lug on the rear member M and reduced and threaded at its upper end, as at 52. 53 is a tube pivoted at its upper end to a lug on the front member m and having the upper portion of its body reduced on its interior, as shown at 54. The rod passes into the lower end of the tube, with its shoulder standing just inside the same, and a spring 55 is wound around said rod between its shoulder and the shoulder within the tube, rubber washers 56 being interposed between the ends of the spring and the metal faces, against which they strike to prevent noise. Above said tube-shoulder a nut 57 is placed on the threaded portion of the rod, and another spring 5S surrounds the upper end of the rod between this nut and the closed upper end of the tube, rubber washers 5b' being used, as above. The upper side of the tube is left open above its center, whereby-a wrench maybe inserted to turn the nut 57. The larger spring 55 holds the'two members of the frame normally apart, although allowing a certain motion between them, as when the machine is passing -over rough roads; but the smaller sp1-in g is brought more or less into use by turning the n ut 57, according as the rider is heavy or light or as the machine is to be used over very roughorverysmoothroadsorpavements. The spring-connection C therefore allows the machine to be adjusted as to its springing motion by the rider after it has been turned out from the manufactory. In some cases-as for racing, for instance-it may be desirable that the frame should have no spring whatever, and to allow of this we providea nut 59 on the body of the rod 51, which,rwhen screwed up against thelower end of the tube 53, prevents any motion whatever of either spring, and therefore causes the two frame members to be connected rigidly, as will be clearly understood. The rear end of the frame member M is bifurcated,as seen in Fig. S, and the rear ends of its bifurcated arms 60 carry split boxes ('51, whose members are connected by screws 69, which boxes are adapt-ed to receive splitbearings 62, held therein by screws 63. (See Fig. 5.) Through said bearings passes a shaft 64, to which the hub of the rear wheel is connected, and' ball or cone bearings may be provided within the bear-V ings without departing from the spirit of our invention. At each end of the shaft 64 it is reduced and threaded, as seen at 65, and over this reduced end is passed, first, a washertiG, then a cup-shaped rubber washer or sandband 67, and then a nut- 68, which latter is of IIO such length that it will project beyond the end of the shaft, as shown. Into this projecting end is screwed a plug 68', whereby all dust is prevented from entering the bearing,

' and the sand-band further serves to prevent its admission, as well as to avoid rattling between the parts. Vhen thesplit boxes G1 are tightened by the screws 69, the split bearings 62 are reduced in sizein amanner which will be obvious.

The propelling mechanism P comprises a shaft 70, journaled in a hanger 7l, secured to the under side of the frame member M by f be tightened the pedal-pin '7S will be prevented from slipping outwardly within said slot in case the nut which holds said pin in place should becomeloose. Each pedal consists of a crossshaped casting 79, bored centrally to pass over the pin 7S, and corrugated or square rubbers mounted on pins at eachend of the frame, as usual in bicycles.

The seat-tube T comprises a tube having a iiange S0 at its lower end, through which pass screws or bolts 8l, taking into holes 82 in the rear frame member M, and within this tube. is a rod '63, having depressions Si. A collar S5 surrounds this rod and is adjusted thereon by a set-screw S6, whose point takes into said depressions and whose body extends through a slot S7 in the side of the tube, and a coiled spring SS is inserted within the tube between the upper faces of the frame M and the lower face of said collar. By this spring the rod 823 is pressed normally upward until the set-screw 86 strikes the upper end of said slot. By adjusting the collar on the rod the sustaining force of the spring can be varied according to the weight of the rider and the amount of resilience he desires the seatv shall have. To the upper end of the rod S3 the seat or saddle Sis attached, as will be clearly understood.

The rear brace-fork R consists of apair of rods connected at their front ends to eyes 90 near the upper end of the tube T and at their rear ends to similar eyes 90 in the boXes til at the rear ends of the frame member M. A rod 91 also connects the tube T with the upper end of the-head H, preferably the block 30, holding the handle-bar, whereby when the spring-connection C gives and the frame yields the handle-bar will be maintained at the same relative position from the seat and the opera-tion of steering will not be interrupted. The dust-guard 92 passes over the rear wheel and at its front end has a bracket 93, connected to a similar bracket 94 on the tube T by a screw, and the rear end of this dust-guard is supported by rods 95, rising from the boxes 61 in the usual manner.

96 are foot-rests adjust-ably mounted on the rearmost of the rods 14 by set-screws 97.

From the above description of the several parts of this improved bicycle it is thought the construction thereof will be manifest.

The adjustments of parts to Atake up for wear are effected by the screws and other devices above illustrated and described and need not be rementioned here, as any skilled mechanic or user of machines of this character will be able to make such adjustments without further explanation.
