Description

UNITED STATES PATENT OinICE.l
DAVID S. SHEARER, OF WAUPUN, WISCONSIN.
IMPROVEMENT IN MORTlSlNG-MACHNES.
Specification forming part of Letters Patent No. 107,413, dated September 13, 1870.
To all whom it may concern:
Be it known that I, DAVID S. SHEARER, of Waupun, in the county of Dodge and State of Wisconsin, have invented a new and use ful Improvement in Devices for Cutting Lock- Bolt and other Mortises, of which the following is'a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification, and in which- Figure 1 represents a side elevation of a hand mortising machine or device, constructed in accordance with my improvement; and Fig. 2 a section of the same, taken as indicated by the line w :c in Fig. l, showing the machine as adjusted to its work.
Similar letters of reference indicate corresponding parts.
My invention consists in a hand machine or device mainly designed to be used for cutting the mortises in the frame-work or division-pieces of bureaus and other articles, the same comprising a revolving cutter carried by a swinging yoke, which is adjustable along a slide-bar carried by a clamp that serves to hold the machine to its place. By this machine mortises for lock-bolts may be cut with the greatest ease, r'apidity, and exactness.
Referring to the accompanying drawing, A represents what may be termed the upper, and B the lower, piece of a clamp for holding the machine to the division-piece or wood in which it is required to cut the mortise.
To secure a steady hold and prevent the machine from turning when at work, said clamp is provided with two or more clamping-screws, C C, arranged to pass through the lower piece B at a suitable distance apart.
D is a yoke for carrying, in a transverse relation to it, the cutter-shaft F, on which is secured the cutter Gr, that is revolved by a crank or handle, H, made fast to said shaft.
This cutter G is formed of a series of segmental cutters, sharpened not only at their advance ends or noses a, but'also formed with beveling sides or cutting-edges b of graduallyincreasing depth from the noses of the cutters.
Such style of cutter I find Well adapted to perform the work designed for it, but a different construction of revolving cutter may be substituted.
The yoke D is hung upon a slide-bar, I, which is free to turn in bearings cc, arranged to project from the top piece A of the clamp.
J is a set-screw for holding the yoke i'n place on the slide-'bar after the cutter has been adjusted to cut the required mortise. On slackening said set-screw the yoke may be adjusted along the slide-bar I to gage the cutter to its work.
The cutter-shaft F has a screw at its one end to keep it from working endwise to prevent displacement of the cutter after it has been set to cut the mortise. The slide-har I is also restrained from working endwise.
After the machine has been securely clamped What is here claimed, and desired to be se-l cured by Letters Patent, is-
The combination of the swinging yoke D and revolving cutter G with the clamp A B and hinge-bar I, substantially as speciied.
DAVID S. SHEARER.
