WITNEssEs g/Lwx /d 55M' gf-/L/ ALEXANDER P. MORROW, OF ELMIRA, NEW YORK.
BACK-PEDALING COASTER-BRAKE.
To all whom it 'may concern:
Be it known that I, ALEXANDER P. MOR- Row, a citizen of th'e 'United States, and resident of Elmira, in the :County of Chemung and State of New York, have invented certain new and useful Improvements in Back- Pedaling Coastenrakes, of which the following is a specification.
This invention relates to back pedaling coaster brakes, and consists in the apparatus hereinafter described and claimed.
In the drawings Figure 1 is a vertical section through a rear hub of a bicycle embodying this invention; Fig. 2 is an elevation of a hub containing the same inven-v tion, parts being removed to show the interior construction, and parts being shown in section; Fig. 3 is an elevation of a detail hereinafter described; Fig. 4 is a cross section on the line 4 4 of Fig. 3; Fig. 5 is an end view of clutch elements employed in the device; Fig. 6 is a vertical section on the line 6 6 of Fig. 5; Fig. 7 is a cross section on the line 7 7 of Fig. 6; Fig. 8 is an end elevation; Fig. 9 is a sideelevation of the end for expanding the brake blocks; Fig. 10 is an elevation of the sprocket Whee, its sleeve and screw: and Figs. 11 and 12 are, respectively, a side elevation and an end elevation of one of the brake blocks.
A hub 1 of usual form is employed in this device, which is provided with cups 2 and 3 for its ball bearings. At one end of the hub vis the 4s rocket Wheel 4 suitably fastened upon a s eeve 5 that extends within the hub, and has upon it the screw threads 6. This sleeve and the sprocket wheel may' be called the driver. The outside of the sleeve constitutes a cone corresponding with the ball bearing cup 3. The said sleeve has also an I internal cup 7 for a ball bearing, the cone 8 of which is carried by the axle 9.
A driving clutch and a brake are provided, which are actuated by a device controll'ed by the backward or forward rotation of the sprocket wheel 4 and the sleeve 5. Upon the threads 6 of said sleeve runs a nut or block 10, having upon it two wedges 11 and 11, as shown most clearly in Figs. 8 and 9. The nut is adapted to move in guide-ways parallel to the axle in a brake sleeve. In the form shown, ,the nut has splines or feathers 12 u on it, having the faces 13 parallel to eac other and to the axis of the nut. The brake carrier 14 has' a clutch member 15 at one end that is adapted for ySpc-:cifcaton of Letters Patent.

engagement with a similar clutch member 16 upon the hub. These two clutch members, as shown in Fig. 2, may be toothed in order to engage each other positively. The brake carrier 14 carries also a ring 17 inside and concentric with the clutch member 15, which is pressed forward from the carrier 14 by means-of a series of springs 18 set in sockets in the ring, and ressing with their free ends against the en( of the brake carrier. The action of these springs forces the ring 17 against an abutment 19 adjacent to the clutch member 16, so as to tend to disengage the two clutch members 15 and 16. ln the present form of the device, the abutment 19 is made as a part of a ring carrying the clutch member 16, which is rigidly fastened into the interior of the hub 1.
On the other end of the brake carrier 14 is another clutch member 20 that is adapted to engage a clutch member 21 on a stationary member or block 22 that may be fastened upon the axle 9, and which is held stationary by a brake arm 23, which is fastened t0 the frame -of the bicycle in any suitable way. The block 22 in the present case forms the cone of the ball bearing, of which the cup 2 is an element.
The brake carrier 14 has a peripheral groove in which lie the brake members 24, which may carry shoes 25, if desired, as in the form shown. The brake members 24 are semicircular, as shown in Figs; 1 1 and 12, and at their contiguous edges have beveled portions 26 for coperation with the wedges 11 on the nut 10. The splines 12 on the nut 10 run in slots 27 in the brake carrier 14, so that said wedges can move only axially. The backs of the wedges are-adapted to abut against a face 29 on the brake carrier 14, when the nut is moved in one direction, and the angular faces of the wedges strike on the beveled faces 26 of the brake members and separate said brake members to press them against the interior` of the hub, when the nut is moved in the other direction. A Wire spring 30 passes around the two brake members, preferably in a groove 1n them, and kee sthe said brake members in position on the rake carrier, and at the same time tends to contract them when the wedges 11 are out of action.
The interior of the sleeve 5 may run 011 a portion of the axle, such for instance as the enlargement 31 thereof.
In order to tend to disengage the members 20 and 21 of the brake clutch, one of said members, such as the block 22, carries the ring 32 that is held in place by the nut 33 having a portion overlapping a portion of said ring 32, and springs 34 interposed between the ring 32 and the block 22 tend to press the ring away from the block and t force the brake carrier 14 so far away from the block 22 that the clutch members 2O and 21 are separated. The member 21 ofthe brake clutch and the member 16 of the driving clutch are at such a distance apart that the brake carrier 14, when held by the rings 17 and 32, is in an intermediate position with both clutches disengaged, and, of course, for this purpose the brake carrier 14 must have a length lessl than the distance between the A clutch members 21 and 16.
The operation of the device is as follows: Assuming that as usual the sprocket wheel 4 is on the right hand side of the bicycle, upon forward driving the sleeve 5 will be turned and its screw threads will shift the nut 10 toward the right in Fig. 1 so that the nut, or, as in the present case, the rear ends 28 of the wedges 11 will force the brake carrier 14 toward the right, compressing the springs 18 under the ring 17, and causing engagement between the clutch member 15 on the brake carrier and the clutch member 16 on the hub. When this engagement occurs and the forward pedaling is continued, the driver mechanism is-rigidly locked to the hub, so `that the hub may be driven thereby. If now the pedals are held stationary, the sprocket wheel 4 and sleeve 5 become stationary also, While the hub 1 continues its rotation. rI he pressure of the springs 18 through the ring 17 agamst its abutment 19, together with the momentary tendency of the brake carrier 14 to move with the hub,'separate the clutch members 15 and 16, but the clutch members 20 and 21 are not thus engaged. Remembering that in this position the brakes and brake shoes are not in contact with the hub, it will be seen that the hub can revolve freely, while the pedals and the parts above mentloned remain stationary and the wheel free, or, in other words, the bicycle may coast; but if the rider back pedals, the motion of the sprocket wheel 4 and of the sleeve 5 is contrary to that occurring when forward drivlng occurs, and the nut 10 is shifted toward the left in Figs. 1 and 2, forcing the ring 32 ahead, of it, and compressing the springs 34 until engagement occurs between the clutch members 20 and 21, whereupon, because the clutch member 21 is always stationary, the brake carrier 14 becomes stationary, and on further back pedaling the nut 10 is carried farther toward the left, thereby causing forcible separation of the brake members 24' through the action of the wedges 11, until a suflclent braking pressure occurs against the hub. On stoppmg the backward pressure,
` and assembling.
esamiA or upon resuming forward pedaling, the ring 32 forces the brake carrier 14 away from the t will be noted that this device is particularly adapted for easy repair, dismounting The brake carrier 14 is itself a block carrying the driving and brakingclutches, and the brake shoes and the actuating nut 10 with its wedges are also carried in and by said brake carrier. The
are all carried by the axle 9, so that these parts may be inserted into the hub, after the brake carrier and its connected parts have been inserted into the hub.l These two insertions occur from the left hand end in Fig. 1. Thereupon the driving mechanism, including the threaded sleeve 5,- is inserted from the other end of the hub and the cone 8 is screwed upon the axle 9, thus assembling all the parts.
