MlTER-BOX.

PECIPI'LATION forming part of Letters Patent No. 374,868, dated December 13, 1887.

Application filed July 6, 1887. Serial No. 243,5l3. (N0 model.)

T0 at whom it may concern:

Beit known that I, EDWARD L. GAYLORI), a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Miter-Boxes; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain novel and useful improvements in miter-boxes, and has for its object to provide an exceedingly simple and durable device whereby moldings and the like may be sawed for the purpose of making a miter-joint; and with these ends in view my invention consists in certain details of construction and combination of elements, as will be hereinafter fully set forth, and then specifically designated by the claims.

In order that those skilled in the art to which my invention appertains may more fully understand the same, I will proceed to describe its construction and operation, referring by letter to the accompanying drawings, forming a part of this specification, in which Figure 1 is a perspective of my improvement; Fig. 2, aplan View of the same; Fig. 3, a section taken at the line a: a: of Fig. 2; Fig. 4, a detail longitudinal section taken through the clamp guide-box, and Fig. 5 a perspective of a planer adapted to operate in connection with my improvement.

Similar letters denote like parts in all the figures.

My improved miter-box is preferably made in two sections, A B, the former adapted to be secured to any suitable bed or table, 0, and the latter adapted to slide on bearings or tracks D, projecting upward from the former. Both sections are provided with wings E, which meet at an angle of forty-five degrees. ,The section A has a slot, F, extending longitudinally and through the section B, and within-said slot extends a clamping-bolt, G, the head of which has a bearing against the section B, while the lower extremity of said bolt runs through a lock-nut, H, adapted to slide on suitable bearings, 1, depending from the bottom of the section A.

From the foregoing description it will be readily understood that the sections A B are stationary and movable, respectively, and that the latter may bereadily moved upon its bear ings and secured in any desired position by means of the clamp-bolt G, the object of which will be presently explained. To the stationary section A are bolted or rigidly secured boxes J, which are open in the direction of their length, as seen at K, and within said boxes are clamp-carriers L, arranged to slide freely therein. The inner extremity of each clampcarrier is headed, as seen at M, for the purpose of retaining said carriers within the boxes J, and an ordinary friction-spring, N, is placed between each carrier and one of the walls of the boxes, in order that the carriers may remain at any point within the boxes to which they are adjusted and not drop by gravity.

Extending through the outer extremities of the carriers L are threaded clamping-rods 0, provided with any suitable crank-handles, P. On the inner ends of these rods are secured buttons Q, made of rubber or other suitable material which will not indent the moldings. To the inner end of the movable section B is secured the molding-support R in such manner that the upper edge thereof is about on a level with the apices of the angles made by the meeting of the wings E.

The operation of my improvement is as follows: The bolt G is loosened and the'section B moved backward to permit of the insertion of the molding between the two sections. The molding is placed upon the supportR, and the clamping-rods O are operated to throw the buttons Q firmly against the molding, the carriers L having been previously adjusted so that the buttons will impinge against the molding at the top and bottom, or at any other desired part thereof, and the movable section having been seen red in its adj ustment, so that the operation of the clamping-rods will bind the molding firmly between said sections. An ordinary handsaw is now placed flat against the wings E and operated to out the molding, said wings acting as guides for the saw. After one side of the joint has been cut from the molding the saw is placed flat against the opposite wings and operated in the manner before described to cut the other side of thejoint. The wings act as guides for the saw, and I have shown and described two pairs of these wings; but although a broad bearing is thereby afforded for the saw a single pair of these wings will answer for this purpose, it being necessary only to steady the saw and prevent any cross cutting.

The wings may be faced with glass, porcelain, steel, or any other material hard enough to prevent accidental cutting therein by the saw-teeth.

From the foregoing it will be obvious that my improvement is asort of clamp for holding moldings, one or both sections of said clamp being provided with guide-wings for the sawblade. The movable section is advantageous in manipulating moldings of various sizes and styles.

If desired, a guide, S, may be secured to the stationary section, and any suitable planingtool, T, placed on said guide and operated to plane the sawed edges of thejoint; but I will not in this application describe or lay claim to such planer, it being my object to merely illustrate the application of said planer to my present improvement.

What I claim is- 1. A miter-box formed of two sections, one adapted to slide horizontally upon the other, one or both sections having a saw-guide comprising oppositely-inclined and upwardly-extending wings, in combination with a set-nut for securing said sections in adjusted relative position, substantially as set forth.

2. In a miter-box, the combination, with a stationary section, a movable section adapted to slide thereon, and a set-nut for securing said sections, both sections provided with angularly-arranged wings, of'clamping-screws carried by the movable section and having a vertical adjustment, whereby said screws are adapted for securing different widthsof molding, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
