UNITED STATES I PATEN Critics.
GERARD BANCKER AND ANDREV CAMPBELL, OF NEV YORK, N. Y.
IMPROVEMENT IN MECHANISM FOR TRANSMITTING ROTARY MOTION.
Specication forming part of Letters Patent No. 2l ,93st, dated November' 2, 1858.
To a/ZZ whom, it may concern,.-
Be it known that we, GERARD BANOKER and ANDREW OAMPBELL,of the city, county, and State of New York, have invented certain new and useful Improvements in Mechanism for Obtaining Rotatory Motion from a Rectilinear Motion; and we do hereby declare the following' to be a full description of the same.
The nature of our invention consists in attaching to the frame of a crank-shaft an extension-rod having' on its lower end a friction-roller, over which and another roller secured on the crank-shaft is arranged an endless belt or band. This is operated bymeans of a sliding clamping-block on the extensionrod, in combination ywith a double-acting clamping-lever the fulcrum of which is secured in the sides ot' the clamping-block, so that as the outer end of the clamping-lever is operated by' a pistonrod or other rectilinear motion the clamping-edges of the clamping-lever alternately impinge one side of the belt against the clamping-block, which, sliding up or down, as the case may be, on the extension-rod, causes the belt to rotate, and thus by clamping alternately the opposite sides of the belt at each half-stroke of the piston-rod keep up a continuous motion in the crank-shaft.
To describe our invention more particularlywe will refer to the accompanying drawings, forming a part of this specification, the same letters of reference, wherever they occur, referring to like parts.
Figure lis a side view of the apparatus as applied to the crankshaft. Fig. 2 is an edge view of the apparatus and belt. Fig. 3 is a plan view of the apparatus and belt through the line a; Fig. 2.
Letter A is a crank-shaft arranged in any suitable frame B for propelling purposes. Attached to the frame is a rod C of any required length, and having at its lower end a friction-roller D, over which `and a second roller or pulley E on the crankshaft is an endless band F for transmitting rotary inotion to the crank. To do thisa sliding clamping-block G is adjusted on the rod C, so as to allow it to slide up and down Von the rod between the sides of the endless band and the friction-rollers at the end of the rod and on the crank-shaft. Attached to this clampingblock, and at right angles to it, is secured by a center pin H a clamping-lever 1,.the sides of which are joined together by braces j and 7i', so as to inclose or embrace the opposite sides of the endless band, but leaving space enough between them and the sides of the clamping-block for the free passage of the alternate sides of the band when not clamped by the action of thepiston-rod L on the outer end My of the clamping-lever.` It will be observed that the bracej is not on a line with the edge of the brace 7c, and both are above the axis or fulcrum of the lever. The object of this arrangement is to cause the braces to impinge the band against the sides of the clamping-block at each alternate stroke of the piston instantly on the reversal of its motion.
The operation of the apparatus is that when the piston-rod attached to the outer end of the clamping-lever is moved downward in the direction of Ithe arrow, Fig. 9, it causes the brace 7e' to clamp one side ot' the band against the clamping-block and releases the opposite side of the band from the clamping-brace j, and as the clamping-block is then permitted to slide on the rod C, the whole is carried forward to the end of the stroke of the piston to revolve the crank-shaft. Immediately the stroke of the piston is reversed the end M of the clamping-lever is forced upward, so as to cause the clamping-bracej to impinge the band against the clampingblock, and at the same time releasing the band from Ithe clamping-brace 7c, so as to allow the return-stroke of the piston to be made, and thus continue the revolution of the crank-shaft and keeping up a continuous rotatory motion therein.
Letter l? is a ily-wheel att-ached to the crank-shaft. This fly-wheel is not material for various purposes to which the apparatus may be applied; but where much leverage is exerted by the crank of the crank-shaft for propelling purposes it is deemed best to use the iiy-wheel as securing a more steady niotion.
Having now described our invention and operated in the manneiand for the purposes its operation, we will proceed to set forth heieinbefore set forth. What- We desire to secure by Letters Patent of the United States. GERARD BANCKER.
That We claim is- A. CAMPBELL. The use of jshe combination of: I@he siiding- 'Witnessesz damping-bleek G and extension-rod C with PETER R. ROACH,
the double-acting clamping-lever, made and CHARLES L. BARRITT.
