SAMUEL P. GLUNT, OF UNIQN CITY, INDIANA.

SLATE-CUTTER.

SPECIFICATION forming part of Letters Patent No. 552,364, dated December 31, 1895.

Application filed, May 15, 1895. $6113.]. NO- 549,43 '7. (N0 model.)

To all whom it may concern.-

Be it known that I, SAMUEL P. GLUNT, of Union City, in the county of Randolph and State of Indiana, have invented a new and Improved Slate-Cutter, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved slate-cutter which is simple and durable in construction and designed for the use of slaters, to enable the latter to properly, conveniently and quickly trim the slate as required, and to provide the same with nail-holes previous to placing the slate on the roof.

The invention consists principally of a knife adapted to swing, and formed with two parallel cutting-edges separated by a longitudinal groove.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the improvement. Fig. 2 is a transverse section of the same on the line 2 2 of Fig. 3. Fig. 3 is a longitudinal sectional side elevation of the improvement. Fig. 4 is a sectional side elevation of a modified form of connection between the knife and operating-lever, and Fig. 5 is a plan view of the same.

The improved slate-cutter consists of a frame A provided with two longitudinally-extending bars A and A held a suitable distance apart, and formed at their ends with .legs A and A, preferably made in the shape of points, so as to conveniently attach the frame to a board, block or like device by driving the points into the wood. The two longitudinal bars A and A support a transversely-extending pivot 13, on which is pivoted the cutter 0, formed with two cuttingedges 0 parallel to one another and separated by a V-shaped groove, as is plainly illustrated in Fig. 2. The rear end of the cutter 0 carries a pivot D passing through an elongated slot E in a lever E fulcrumed at D on the bars A and A and adapted to impart a swinging motion to the latter. The lever E is formed at its outer end with a handle E adapted to be taken hold of by the operator to impart a swinging motion to the said cutter, to cause the cutter O to cut the slate placed on the bars A and A in front of the cutter, as indicated in Fig. 1.

On the handled end E of the lever E is arranged a pin F, operating over an aperture A in the leg A to enable the operator to punch holes into the slate by placing the latter over the aperture A and then bringing the lever E down, so as to force the pin or punch F through the slate. The connection between the lever E and cutter C may be made in various forms-for instance, as shown in Figs. 4 and 5, in which the pivoted cutter O is provided on its pivot end with gear-teeth C in mesh with corresponding teeth E secured on the forward end of the lever E Now when the latter is moved upward, a like upward swinging motion is given to the cutter C and when the lever is brought down the cutter O swings downward to trim the slate, as previously mentioned.

It will be seen that this device is very simple and durable in construction, and by the use of the double cutting-edges of the cutter the cut particles of slate give away readily, so that a straight edge may be cut on each part of the slate.

The cutter O is preferably made in two parts, as indicated in the drawings, to admit of the parts being turned on the pivot, to allow them to be easily sharpened whenever necessary.

In order to limit the downward-swinging motion of the lever E when punching holes in the slate by the pin or punch F, I provide a stop G, connecting the two bars A and A with each other, the said stop being engaged by a recess E formed in the lever, as is plainly shown in Fig. 3. The slot E permits the lever and knife to be turned from a straight line in raising the lever-handle during the cutting and punching operation.

Having thus described my invention, I claim as new and desire to secure by Letters Patent In a slate cutter, the combination with a framecomposed of two bars having parallel portions spaced apart and having their extreniities bcnt downwardly and formed with points, of a knife pivoted between the bars and having its cutting edge capable of moving past the same, and a lever fulcrumed between the bars and pivotally connected to the knife, the lever having at the end opposite the knife a downwardly projecting pin or punch, substantially as described.
