GUSTAVE KINDERMANS, OF VILVORDE, BELGIUM.
BICYCLE-CHAIN-ADJUSTING MEANS.
To all whom it may concern:
Be it known that I, GUsTAvn KINDERMANS, a subject of the Belgian King, and residing at Vilvorde, Belgium, have invented new and useful Improvements in Bicycle-Chain- Adjusting Means; and I do hereby declare the following to be a full, clear, and exact description of the same.
My present invention relates to means for adjusting the chains and mounting the driving Wheels of bicycles and the like, characterized by the fact that on the usual flat pieces to which the tubes of the rear forks of the frame are attached, are adjustably arranged blocks provided with open vertical slots to receiye the ends of the driving wheelaxle and having on op osite sides longitudinal screw-threaded roc s, one of which extends freely into the tube of the lower fork and may be secured by means of a screw-nut while the other is gulded in a slotted lug of the said flat piece and secured by two screwnuts, a screw-bolt extending through the upper part of the adjustable block and a longitudinal slot in the flat piece, for the purpose of securing the adjustable block at three different points and thus preventing it from moving accidentally on the said flat piece.
The invention will be readily understood from the following description taken in connection with the accompanying drawings, in which:
Figure 1 is a side elevation showing the outer side of the fiat piece connecting the tubes of the frame and the chain adjusting means mounted on said flat piece. Fig. 2 shows the inner side elevation of same. Fig. 3 shows the fiat iece with the adjusting means removed. ig. 1 shows the adjusting means removed from the flat piece, and Fig. 5 is the outer side elevation of the flat piece and the adjusting means, showing a modification.
Specification of Letters I'atent.
Application filed March 25, 1910.
Patented Nov. 1, 1910.
Serial No. 551,561.
the sliding-block and the longitudinal slot of the fiat piece 1 serving to secure the block on the latter.
The sliding block 3 is made integral with screw-threaded rods 5, 5 extending from opposite sides, and one of which extends into the lower horizontal tube and may be seecured by a screw-nut 6, while the other is guided 1n an open vertical slot 7 provided in a dependin lug 2 of the flat piece 1 and may be secured by means of two screw- nuts 6, 6. After loosening the inner screw-nuts 6 6 and screw-bolts 9, the tension of the chain may be easily adjusted by turning the outer nut 6, bearing against the outer side of the piece 1 and causing the block 3 to slide longitudinally on sand piece 1. The tension of the chain being ad usted, the in- Her screw- nuts 6, 6 are tightened against the lug 2 and the horizontal frame-tube respectively and the screw-bolt 9 is also tightened 1n the block 3. In this way, the latter will be secured at three different points so that it cannot be accidentally moved when the wheelaxle is removed from or mounted into the slot 4 of the block 3.
In the modification shown in Fi 5, the rear threaded rod 5 is guided and held be tween two horizontal jaws 7, 7 of the lug 2, and the sliding block 3 has a single upper part 3 (not orked) sliding on the inner s1de of the piece 1. In this modification, the block 3 may be removed laterally from the piece 1, whereas in the construction shown in Figs. 1, 2, 3 and 1, the block 3 must be removed downwardly.
It will be seen that in the present arrangement the slide block 3 and therefore the driving wheel-axle may be adjusted forwardly and rearwardly owing to the screwthreaded rods 5, 5 and nuts 6, 6, 6' mounted on the same, while in the old arrangements the wheel-axle can only be adjusted rearwardly. On the other hand after tightening the screw- nuts 6, 6 and the bolt 9 of my arrangement, the wheel axle cannot be moved rearwardly as in the old constructions wherein a single nut, say the outer nut 6, is provided for holding the adjustable part in place.
Havin fully described my invention, what I claim and desire to secure by Letters Patent is 1. In a bicycle-chain adjusting device, the combination with the rear forks, a fiat piece connecting said forks, and a horizontal slot in said fiat piece, of a slotted sliding-block, a screw-bolt extending through the upper part of said block and through the horizontal slot of the flat piece, a screw-threaded rod made integral with said block and eX- tending freely into the lower horizontal fork, a screw-nut on said rod between the fork and the sliding-block for securing the rod in place, a second screw-threaded rod made integral with the block and extending from the opposite side thereof, means for guiding said second rod in the fiat piece, and means for securing it in adjusted positions, substantially as set forth.
2. In a bicycle-chain adjusting device, the combination with the rear forks, a flat piece connecting said forks, and a horizontal slot in said flat piece, of a slotted sliding-block, a screw-bolt extending through the upper part of said block and through the horizontal slot of the flat piece, a screw-threaded rod made integral with said block and extending freely into the lower horizontal fork, a screw-nut on said rod between the fork and the sliding-block for securing the rod in place, a second screw-threaded rod made integral with the block and extending from the opposite side thereof, a depending H GUSTAVE KINDERMANSQ Vitnesses CHARLES HOOVER, GREGORY PHELAN.
