C L'ARK M. LA NGLEY, O F LVVELL, MASSACHUSETTS team Patent No. l68,212, dated August 27, 1867.
IMPROVEMENT N THE MODE OF DRIVING PRINTING-PRESSES.
TO ALL WHM IT MAY CONCER:
Be it known vthat I,- CLARK M. LANGLEY, of Lowell, in the county of Middlesex1 and State of Massa'chu# setts, have invented anew and useful improvement in the Mode of Driving PrintingyEresses and I do hereby declare that `the following is a full and exact description thereof', reference being had to the accompanying drawing, making 'a part of this specification.
The drawing marked C H S is a perspective view of the mechanism herein described.
My improvement in driving printing-presses relates chiefly to the mode of changing the velocity of the press in order to adapt it for producingl the finest kinds of work, or: coarse and ordinary styles; -and-a'lso to change the velocity while any particular job is in'progresswithout stopping the press; alsoby this use of a driving power of variable 'velocity the speed of the press is regulated in accordance with the condition of' the f01m','the consistence of the ink, changes of temperature, andthe hydrometric condition of the paper. This is eected by the use of double conical drums, or pulleys, and attached mechanism, as s hown in the drawing.
The ceiling or top of a vroom is represented at Z, and depending from it are the hangers V V', which snpf port the conical drum H T, and-the hangers J K, whichhold the shipping mechanism. Upon the .opposite side,
at any convenient distance, is the conical drum C D, turning in the bearings A A-,'and driven by a belt from,
the prime moverLapplied to the pulley F. The large end C is opposite to the small end H of the first-named drum, and the small end D is opposite to the. large end T, thel respective shafts of the two drums being parallel lwith-each other. The printing-press is driven by the` belt Y, passing around the tight pulley X, which is of' the same size as the large end l` of the conical drum; this belt Y is slipped upon the loose pulley W when the press is to be stopped. The belt G leads from the drum D to the drum H T, and drives the lat-ter; The drum C D turns at a uniform rate, and the velocity of the belt Yidepends upon the position of the belt VGr upon the two 'cone drums, the speed being 'great-est when the belt G-runs from the large end C to thesmall end H, and least when it runs from D to T. The position ofthe belt upon the drums is governed at willby the attendant by pulling the cord L (which hangs down over the press) to the right or left. The cord passes'over the pnlleys M `M/ and is fastened to `the shipper-bar O P, which is parallel with the drulnfv Upon it are two guide pins E, nearly in contact with the edges of-the' belt G. This shipper-bar slides in suitable guides, and is retained in any required position bythe spring R B, one end of the spring being made fast, and thc free end bearing'upon the shipper-bar.
What I claim, and desire to secure by Letters Patent,.i s-
The spring B, which retains the shipper-barand driving-belt in any required position,.in combination' with the cord L, the shipper-bar O Pfand thevdouble cones, substantially as herein described.v
