COMPRESSIBLE GAGE.

SPECIFICATION forming part of Letters Patent No. 295,927, dated April 1, 1884.

Application filed August 7, 1883. (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. LIEB, of the city, county, and State of New York, have invented, made, and applied to use an Improved Oompressible-Gage to be Used in Connection with Paper-Cutting Machines; and I do hereby declare the following to be a full, clear, and correct description of my invention,

' reference being had to the accompanying drawings, making part of this specification, i and to the letters of reference marked thereon,

in which- Figure 1 is a front view of my compressible gage. Fig 2 is a top view of the same. Fig.

3 is a View of one of the sections composing the gage. Fig. lis a'front view of gage when I in improvements, as more fully hereinafter set forth, in the construction of a compressible gage for use in paper-cutting machines.

To enable those skilled in the arts to make and use my invention, I will describe its construction and operation.

Ashows a series of links of equal length and width, of which the gage is composed. These links A are milled or turned down at one end, as at a, to form shoulders orears to receive the unmilled or unturned-down ends of the adjacent link. The ends of the links are also rounded, as at b, so that the links A, when united, shall be free to move readily, and thus admit of the compression of the gage. The links A are secured together by placing them in the inclined position shown, the ends of one link beingreceived and resting within the recessed portion of the adjacent link, and then passing through openings in the links the journals B, which form, as it were, pivots upon which the links A are free to move.

Over these journals B are passed the helical springs 0, one end of each spring being connected to and having a bearing upon one of the links, and its opposite end being connected to or having a bearing upon the adjacent link.

Over the central j ournal, B, may be placed a rubber cushion, D, sufficiently large in circumference to allow it to project above the helical springs 0.

Such being the construction, the operation may be thus described. As stated, the gage is intended to be employed in connection with a paper-cutting machine, where it is desired to trim labels or strips of paper or other material so narrow that the ordinary back gage of the machine E, owing to the presence of the clamp ll of the machine, can not be advanced sufficiently to form a back support for the labels or strips of paper to be trimmed or cut. The gage is placed upon the table G of the machine, directly beneath the clamp F, and the links A have a bearing against the face of the gage E of the machine, as their rear ends rest against the same, and

their front ends form a bearing for the labels or paper to be trimmed or out. As the clamp F is depressed it bears upon the upper side of the gage, compressing the same, and the links A are brought from their inclined position into the position shown in Fig. 4c of the draw-v ings. As the clamp F descends, it first comes into contact with the-rubber cushion D, so that as it continues its downward movement the gage will be compressed without disturbing its position, and when the clamp F has been brought to its full extent the gage has been compressed without changing its position or disturbing the paper, which is now held firmly upon the table G, and the knife H of the ma chine may now be brought down upon the paper and cut or separate the same to the eX- tent that it is allowed to project beyond the gage. As the links are compressed, the helical springs O are expanded, and after the cut paper has been removed and the knife H and clamp F have a return or upward movement imparted to them, the construction of these 7 springs 0 causes the links Ato return to their normal position. It will also be seen that the clamp F first impinges upon the rubber cushion D, placed above the links A, so that the compression of the gage can be efiected without a disturbance of its position, which isan important feature.

It will be readily seen that the gage can be lengthened by adding one or more links, which can be easily done when required.

Having now set forth my invention, IclaiIn 3. The combination of a series of inclined as newlinks, A;-' journals B, helical springs O, and

1. A compressible gage formed by conibinthe rubber cushion D, constructed and opering a single series of links, which are united ating substantially as and for the purposes 15 5 at their ends, and form an unbroken surface specified.

against which the paper or other material to be out can be placed, as set forth. CHARLES A. LIEB.

2. The links A, united at their ends'by the rods B, in combination with the springs C In presence of IO around such rods, and bearing on the links, as WILLIAM V. H. HICKS,

set forth. A. SIDNEY DOANE.
