VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 425,017, dated April 8, 1890.

Application filed December 3, 1889.

To aZZ whom it may concern:

Be it known that we, LOUIS BARROW an CHARLES HENRY GUEST, subjects of the Queen of Great Britain, residing at Birmingham, in the county of Varwick, England, have invented a new and useful Improvement in Velocipedes, (for which we have obtained a patent in Great Britain, No. 11,421, bearing date July 16, 1885),) of which the following is a specification.

Our invention relates to improvements in the frames of those velocipedes having two wheels, one in front of the other, the front one being operated to steer and the rear one to drive the machine, (commonly known as ,rear-driving Safety bicycles;) and it consists in forming that part of the frame carry-- ing the driving-wheel, pedal crank-axle, and seat for the rider of iron or steel bars of a crescent or other suitable section, and in bolting or riveting the several parts together.

The objects of our improvements are, first, to provide a frame which can-be constructed without skilled labor 5 secondly, to provide a strong and rigid frame out of bar iron or steel or itsequivalent, and, thirdly, to reduce the cost of manufacture. We attain these ends in the manner illustrated in the accompanying drawings, in which- Figure 1, Sheet No. l, is a view in side elevation of a rear-driving Safety bicycle, the frame of which is constructed according to our invention. Fig. 2, Sheet No. 2, is a view in sectional elevation, on an enlarged scale, of our improved frame. Fig. 3, Sheet No. 3, is a view in sectional plan, on an enlarged scale, on line 00 00, Fig. 2, Sheet No. 2; and Fig. 4, Sheet No. 3, is a view in front elevation, on an enlarged scale, of the frame.

Throughout the several views similar parts are marked with like letters of reference.

The frame carrying the driving wheel, pedal crank-axle, and seat for the rider consists of thirteen members, formed of lengths of bar iron or steel of a crescent or other suitable section, numbered in the drawings 1 to 13, inclusive, of a center spindle 14, forming part of the steering joint or head, a socket 15 for the seat-pillar, and a cross-bar 16, carrying the bearings for the pedal crank-axle.

Serial No. 332,477. (No model.) Patented in England July 16,1889, No.11,421.

These form the essential parts of our improved frame. The part of the frame carrying the steering-wheel presents no novel features and may be of the well-known type.

The several parts of the frame are arranged and connected together in the following manner: The cross-bar 16 is preferably formed of increased diameter at or about the center of its length to receive a swinging bracket 17, carrying the bearings 18 for the pedal crankaxle. Onto the reduced ends of the cross-bar are placed the ends of nine of the members of the frameone on each side thereof, and preferably in the following order: members 1 and 2 forming the horizontal fork carrying the driving-wheel, 3 and 4 running vertically to support the seat-pillar socket 15, 5 and 6 running to the top of the center spindle 14,

7 and 8 running to the bottom of the center spindle 14, and member 9 running to the axle of the driving-wheel, forming an additional prong or stay on the opposite side of the horizontal fork to that on which the chain-gearing is placed. In order to splay out the additional prong or stay 9, a washer 19 is placed 7 5 on the cross-bar between it and the other members. The ends of these members are then locked firmly onto the cross-bar by means of nuts threaded on its ends. The free ends of the members 7 and S are fixed to the lower end of the center spindle 14 by a transverse bolt and nut 20. The free ends of the members 5 and 6 are fixed to the top of the center spindle 14, together with two

other members

10 and 11, by a transverse bolt and nut 21. The free ends of the

members

10 and 11 and 3 and 4 are fixed to the socket 15, together with the ends of two other members 12 and 13, by a transverse bolt and nut 22. The free ends of the members 12 13 are adapted, with those of the members 1, 2, and

9, to receive the axle 23 of the driving-wheel and be locked thereto by the nuts on the ends thereof. Instead of the bolts and nuts 20, 21, and 22, rivets maybe used, if desired. 5 The members 3 and 4, 5 and 6, 7 and 8, and

12 and 13 converge at their points of connection to the center spindle 14 and seat-pillar 15, respectively, and they are widest apart at their points of connectionwith the crossbar 10o 16 and axle 23 of the drivingwlieel, respectively. The members 12 and 0 also converge slightly at their points of connection to the cross-bar 16; but the members and 12 run parallel to one another as close together as possible. The center spindle 11 and the socket are provided with suitable lugs, as illustrated, adapted to project between the respective members fixed thereto to stilfen the frame.

It will be seen that as all the members of the frame are bolted or riveted together and not brazed the members 5 and 6 are necessary to the stability thereof, and act as stays to the respective parts of the frame, and also that the member 9 acts as a truss to the fork 1 2, and so stiffens it against the pull of the driving-chain.

To prepare the ends of the several members to be bolted up or riveted to the respective parts hereinbefore set forth, they are stamped or pressed out flat, and a hole of the required size is punched or drilled therein.

The mud-guard 21 presents no novel features, and may be fixed to the

members

1 and 12 and 13, as illustrated, or in any other convenient and suitable manner.

The mechanism we prefer to use to adjust the driving-chain consists of a tension-rod 2G, screwed or otherwise fixed to thelower lug on the center spindle 14-, and adapted to pass through an eye orarm on the swinging bracket 18, carrying the bearings for the pedal crankaxle, and be capable of rocking the swinging bracket on the crossbar-16 by means of suitable nuts threaded on the end thereof. The swinging bracket is locked to the cross-bar 1.0 after adjustment by the set-screw 25. This device forms no part of our invention, as any other equivalent or suitable mechanism may be used. These other parts of the machine to which no specific reference has been made and which are not illustrated in the drawin present no novel features, and may be of the usual type and construction.

\Ve wish it to be understood that we do not limit ourselves to the use of bar iron or steel of a crescent section for the members of our improved frame,as bars of any other section, or even tubes of a flattened section, may be used; and also that we do not limit ourselves to the precise shape or the exact details of locipcde, of the fork l 2, for carrying the driv" ing-wheel, and the additional prong or stay 9, adapted to truss the said fork, as set forth.

2. In the frame of a velocipede, the combination, with the members 1 2 4 7 8 1O 11 12 13, the center spindle 14, the seat-pillar socket 15, and the cross-bar 16, bolted or riveted together by transverse bolts 0r rivets, of the members 5 and 6, acting as braces to the said frame and preventingmovement at the joints, as set forth.

3. In a frame for a velocipede, the combination of the fork 1 2, with additional prong or stay 9, and the fork 12 13, carrying the driving-wheel, the vertical members 3 4, the members 7 S, the members 10 11, the center spindle 11-, the seat-pillar socket 15, the crossbar 16, and the diagonal brace 5 6, all combined, arranged, and operating as and forthe purpose set forth.

In witness whereof we have hereunto signed our names in the presence of two subscribing witnesses.

LOUIS BARROXV. CHARLES HENRY GUEST.
