VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 430,019, dated June 10, 1890.

Application filed March 18, 1890. Serial No. 344,409. (No model.) Patented in England November 1'7, 1888, No. 16,736, and in Germany January 25,1889,No.48,990.

To all whom it may concern:

Be it known that 1, WILLIAM HILLMAN, a subject of the Queen of Great Britain, residing at Coventry, in the county of Warwick,

England, have invented certain new and useful Improvements in Velocipedes, (for which I have obtained patents in England, dated November 17, 1888, No. 16,736, and Germany, dated January 25, 1889, No. 4 8,990,) and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in I 5 the construction of that class of Safety-bicycle frame which is known as the diamondshaped frame and it consists in building up such frames of trough-shaped or crescentsection steel, such as that used for the fellies of wheels.

My invention is illustrated in the accompanying drawings, in which Figure 1 represents a Safety bicycle with parts thereof constructed according to my invention showing a side view of the complete machine, except that the saddle is not shown. Fig. 2 is a sectional plan thereof drawn on the line 1 1 of Fig. 1, but omitting the brake and spokes and rims of the wheels.

0 Fig. 3 is a vertical section of front part of diamond-shapedframe. Fig. 4 is an elevation, as seen when looking forward, of the front part of the frame detached from the back part and from the-mudguard. Fig. 5 is a plan drawn on the line 2 2 of Fig. 3. Fig. 6 is a plan drawn on the line 3 3 of Fig.3, and Fig. 7 is a section on the line 4 4. of Fig. 5. Fig. 8 is a vertical section of the back part or forks of the diamond-shaped frame. Fig.

0 9 is a plan of the upper barsthereof, and Fig. 10 is a sectional plan of Fig. 8, drawn on the line 5 5. Figs. 3 to 10 are drawn to double the scale of Figs. 1 and 2.

I In all the figures like parts are indicated by similar letters of reference.

A is the front or steering'wheel. Bis the rear or drivingwheel. Ois the crank-axle. C are the cranks. C is the crank-chain wheel.

0 are the pedals. D is the driving-axle. D is the chain-wheel thereon. E is the steeringhead. E is the front fork. F is the brake and brake-levers. G are the steering-handles. H is the diamond-shaped frame, and I is the seatpillar.

' The diamond-shaped portion of the frame H is formed of four lengths or bars 71. h h 71 of trough-shaped or felly steel, on each side arranged with the hollows thereof inward or toward each other and nearly meeting at the forward end or neck h, to which they are connected by means of arms 7L stamped or forged in one piece with the neck and fitting within the grooves of the bars h 71 to which they are brazed. The bars h 7L2 are fixed together in pairs by means of distance-pieces h, fitting within the hollows'thereof and brazed thereto, by which means rigidity and strength of frame are secured. The bars h are connected together at the upper angle of the frame and to the bars h by means of the forging or stampingh having arms h fitting the hollows of the respective pairs of bars h h and brazed thereto. A cross-bar or mudguard h, made of larger section metal than that used for the bars h h 71. hicounects the top and bottom angles of the diamond-shaped frame by means of the forgings or stampings 71. h h in the following manner:

The forging 0r stamping 77. is fitted around and brazed to the cross-bar or mud-guard 72, The forging or stamping it has arms h, fitting and brazed within the hollows of the bars 71 and it is formed with arms 77, fitting around and brazed to the cross-bar or mudguard h", and the forging or stamping h is formed with an arm 71 fitting within and brazed to the cross-bar or mud-guard h, and with arms 71 fitting within and brazed to the hollows of the bars h The forging or stamping h is also formed with a bearing h", to carry the pin or axis of the lug or arm 72, of the crank-shaft'bearing, and with aperforated lug h, through which the chain-tension-regulating screw or bolt 71. passes.

The bars h h on each side of the frame are connected at the rear end by means of a forging or stamping it, having arms or projections h fitting within and brazed to the hollows of the bars h h Thus the bars h 7&3 of the diamoud-shaped frame form a pair of forks, which are connected together on each side by means of the forgings or stampings it, which are also formed with bearings 72? to carry the axle of the driving-wheel B.

The upper end of the cross-bar or mudguard 71, is extended beyond the diamondshaped frame and is forged into the form of a tube kg", and it has brazed thereto at its upper end a collar 79*, formed with lugs 7L which are held together by a screw-bolt, so as to be capable of receiving and adjustably holding the seat-pillar I within the tube N24. The upper end of the mud-guard or crossbar may, however, be otherwise formed or fitted to receive a seat or saddle.

Instead of using trough-shaped or felly steel in the construct-ion of the cross-bar or mud-guard 7r" a tube 1) or other section may be employed.

The baclnrard continuation j of the mud guard is attached to the mud-guard 7L" and to the frame ll by a bolt j, fixed to such backward continuation and passing through a hole in the mud-guard or cross-bar 7L and stamping or forging 7L7 and secured thereto by nutj Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. In the manufacture of the diamondshaped frame of Safety bicycles, the combination of pairs of rods or bars h h 7L2 h of trough-shaped or felly steel, stampings or forgings to connect them together at the angles, distance-pieces h, and cross-bar or mudguard 71 connected to the top and bottom forgings or stampings, substantially as herein shown and described.

2. In Safety bicycles, the combination of a diamond-shaped frame of trough-shaped metal with an upward extension of the crossbar or mud-guard 7L", forged into tubular shape and fitted to receive the pillar or support for the saddle or seat, substantially as herein shown and described.
