GA'GE FOR BOOK-MAKERS TABLE-SHEARS.
sPEcmicA rroiv forming part of Letters Patent No. 265,036, dated September 26, 1882.
Application filed May 15, 1882. (No model.) I
Makers Table-Shears, of which the following is a'specification.
My invention relates to improvements in gages for book-makers table-shears, &c.
The object of my invention is to provide a gage which may be readily adjusted to and secured at any. desired point, the gage always moving parallel with the cutter. I attain this object by the mechanism shown in the accompanying drawings, in which- Figure l is a plan view of a table-shears towhich my improved gage is applied. Fig. 2 is an enlarged sectional view of the gage, and Fig. 3 an end view of the same.
Similar letters refer to similar parts throughout the several views.
In the said drawings, A A represent the main frame of the shears, B the cutter or knife, and T the table, all arranged in the ordinary manner. 0 is myimproved gage, which is provided with the head D at each end, which slides on theways a a on the main frame A A. Each of the headsD is provided with a recess, 0, in which runs a pinion, 10, secured on the end of a shaft, S, which runs in bearings 12 b on the heads D. The pinionspp in the heads D D mesh with racks r a", secured on the ways a a on the main frame A A, the teeth in one of which are coincident with those in the other.
The operation is very simple. To adjust the gage to any desired distance from the cutter or knife it is only necessary to push the gage out to the required point. The pinionspp, being secured rigidly to each end of theshaft S and meshing with the coincident racks r 1", keep the gage at all times parallel with the knife. To secure the gage at any point the hand-screw E is turned up against the hearing I), clamping the bearing firmly between the end of the pinion p and thesaid hand-screw E, and holding the shaft from turning and keeping the gage held securely at the desired point.
It will be seen that this gage is very simple and can be readily adjusted to and secured at any point, the gage always moving parallel to the knife B.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
1. An adjustable gage, 0, having shaft S, with pinionsy) p secured thereto and meshing with racks r r, in combination with hand-screw E on said shaft S, which screws against a bearin g, b, for the purpose of holding the gage, substantially as described and shown.
2. The adjustable. gage (J, having heads D D, provided withithe recesses c c and bearings 11 b, in combination with a shaft, S, pinionsp p, racks a" a", and hand-screw E, substantially as shown and described.
In testimony whereof I affix my sign ature in .presence of two witnesses.
