UNITED STATES PATENT OFFICE.
IVILLIAM BRAIDIVOOD, OF MOUNT VERNON, NElV YORK.
INDEX-CUTTER.
SPECIFICATION forming part of Letters Patent No. 453,103, dated May 26, 1891..
Application filed August 28, 1890. Serial No. 363,247. (No model.)
To all whom it may concern.-
lBe it known that I, WILLIAM BRAIDW'OOD, a citizen of the United States, residing at Mount Vernon, in the county of Westchester and State of New York, have invented new and useful Improvements in Index-Cutters, of which the following is a specification.
This invention relates to improvements in the index-cutter patented in United States Letters Patent No. 417,536, granted to me December 17, 1889, and by means of these improvements the operation of the device is made easier and smoother, as set forth in the following specification and claims and illustrated in the annexed drawings, in which Figure 1 is a front elevation of an indexcutter containing my invention. Fig. 2 is a section along 00 cc, Fig. 1.
In the drawings the letter A indicates a frame or support. The shafts B B are connected by bevel-gears O with shaft D, rotated by the hand-wheel E, and said shafts B carry arms or cams F, on which rests a table G for supporting the book or pamphlet to be operated on. The actuations of the cams I raise or lower the table G, which is guided by the arms I. The detent M,'engaging the toothed wheel L, locks the table at the proper height. These parts need not be described in detail, since they correspond to like parts shown in said Patent No. 417,536 as does also the carriage N, traveling along ways 0 and having a feed-rack P engaged by a gear-wheel Q 011 shaft R. ards U, rising from carriage N, have a bar or rest I), to which the clam pin g-bar is jointed at V, and said clamping-bar can be locked by the catch X, pressed by spring Y and having a handle Z, and a spring a tends to release the bar IV. The detent-rack e of the carriage N is engaged by the pawl g, actuated at suitable intervals by the rod 75 and tappet l on the main driving-shaft m. The cutter o o is arranged to shear off strips of paper from the various leaves.
In place of a weight for rotating the shaft R to feed the carriage N, as in said Patent No. 417,536, the shaft in this case is provided with a friction disk or plate T, pressing against a corresponding friction-piece T on the counter-shaft S. The counter-shaft S has a pulley R, rotated by belt S, communicat- The stand ing with the shaft or. When the carriage N is locked by the pawl g, the shaft S rotates without moving the shaft R or carriage N. Vhen the pawl g is in its releasing position, the friction between the platesT T communicafes rotation from shaft S to shaft B, so as to rotate said shaft R and feed the carriage.
The use of a weight to feed the carriage, as shown in said Patent No. 417,506, I have found to be somewhat inconvenient, since the weight feeds the carriage with such a sudden jerk that there is liability of a re bound of the carriage, whereby the accuracy of the work is interfered with. The employment of the friction-feed T T, shown herein) avoids such jerks and rebounds, so that the device operates smooth and easy.
I find that it is of advantage to place between the metallic friction-surfaces aleatherwasher; but any suitable material may be used for the friction-surfaces.
hat I claim as new, and desire to secure by Letters Patent, is
1. In an indeX-cutter, the combination, with a table, a detent-rack for the table, a pawl for the rack, a main driving-shaft, and means for operating the pawl from the driving-shaft, of a counter-shaft rotated by the main driving-shaft, an independent shaft engaging the table to feed the same, and friction devices for connecting the adjacent ends of the coun ter-shaft and the shaft which engages the table, substantially as.described.
2. In an index-cutter, the combination, with a table and a detent-raek for said table, of a pawl for said rack, a cam or actuator for said pawl, a feed-rack for the table, a gear-wheel for said feed-rack, a shaftfor said gear-wheel, a driving'shaft for the gear-wheel shaft, and friction plates T T, mounted, respectively, in the driving-shaft and gear-wheel shaft, said friction-plates having their adjacent faces pressed together, so as to seou re frictional engagement between said .plates, substantially
