BELT-CUTTER AND SQUARE..

SPECIFICATION forming part of Letters Patent No. 777,038, dated; December 6, 1904.

Application filed March 28, 1904.

To all whom it may concern.-

Be it known that l', FRANK M. LINDEEMAN, a citizen ot' the United States, residing at Chicago, in the county ot' Cook and State oit Illinois, have invented certain new and use't'ul lmprovements in Belt-Cutters and Squares; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

My invention is an improved belt-cutter and square adapted for use in cutting the ends of power-belts either at right angles or on a bevel prior to joining the ends together by any of the common forms of belt-fastening devices; and my invention consists in the construction and combination otl devices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of my improved belt-eutter and square. Fig. 2 is a detail sectional view of the same, taken on the plane indicated by the line a a oi' Fig. 1. Fig. 3 is a similar view taken on the plane indicated by the line of Fig. 1. Fig. 11 is a sectional view oi a moditied form ot' my invention.

ln the embodiment ot' my invention l. provide a square 1 of suitable size and comprising the transverse7 arm 2 and the longitudinal arm 3, so termed because of their disposition with relation to a belt to be cut. The longitudinal arm 3 has a depending flange A at its outer side to bear against one ot' the longitudinal edges ot' a belt, so that the arm 2 is disposed across the same at right angles thereto. A clamp 5 is provided to secure the square on a belt. Said clamp may be either of the form here shown or of any other suitable form. As here shown, it comprises a U-shaped yoke 6, the arms of which are adapted to bear on the upper side of the arm 2 and the under side of the belt, respectively, a clam pingscrew 7 in a threaded opening in the upper arm of the yoke, and a shoe 7/, swiveled to the point of the screw. This shoe engages a guideway 8 on the upper end ol2 the arm 3, where it meets the arm 2. The guideway and shoe enable the clamp to be adjusted as may be required and to be attached to the square and detached therefrom at will. The arm 2 Serial No. 200.485. (No model.)

is preferably provided with a measuring scale 9.

At the outer edge oi the arm 2 is a cutter guide and gage 10. The arm 2 and cutter guide and gage are respectively provided with hinge members 11 12, and a pintle-rod 13 is placed in alined openings in said members, and thereby the guide and gage is hinged to the transverse arm of the square. Said pintlc-rod is detachable to permit ol the detachment oi' the guide and gage and has a head 'let at one end and a thumb-nut at the opposite end, as shown. The guide and gage is longer than the transverse arm ot' the square, and its ends project beyond the ends thereof, as shown. The guide and gage is provided with a longitudinal guide-slot 15, in which the blade ot' a cutter or knife 16 may be placed and through which it maybe drawn to cut oli the end oi" a belt.

On the transverse arm of the square shown a stop-arm 17, which serves when the guide and gage is turned and held pressed against it to hold said guide and gage in such position as to dispose the cutter or knit'e at right angles to the face oli the square, and hence cause the cutter or kniiie when operated manually to cut oli'A the end oi a belt at a right angle. To enable the guide and gage to be held at Ian angle of forty-[ive degrees from the square and cause the end oi the belt to b e cut on a miter, as required when certain 'Forms oi belt-fasteners are to be used, l provide the square and gage on its outer side with a `footflange 18, disposed at an angle ot' forty-[ive degrees with reference thereto. This .footiiange is adapted to bear on the upper side oi. the belt when the same is to be cut, as shown in dotted lines in Fig. Q.

The cutter or knife has a handle 19, by which it may be grasped and operated, and its blade, which operates in the slot 15 oi the guide and gage, has its point reversely curved and beveled, as shown. rlhe blade oi the cutter has a slot E21 for the insertion oi a suitable gage-key 22 to bear on the upper straight edges oit the guide and gage and retain the blade in the required position when in use.

rlrhe transverse arm o'l the square is pro vided with a series of marking-points E20,

lOO

which project from its under side and are appropriately spaced apart, in practice one-half an inch apart and the point nearest the flange 4 at a distance of one-half an inch therefrom. These points when the square is clamped on a belt to be cut enter the belt and mark the places where the fasteners are to be inserted.

In Fig. 4 of the drawings I show a modified form of my invention, in which the cutterguide 23 is rigidly Connected to the square and the guide-slot therein is at right angles to the faces of the square. This form of the invention is adapted for use in cutting the ends of belts which do not require their cut ends to be beveled.

' From the foregoing description.y taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A device for use in cutting the ends of power-belts and comprising a square having a guide element secured on one side and projecting beyond one edge thereof, and parallel with said edge to correspondingly direct the blade of a cutter.

2. A device for use in cutting the ends of power-belts and comprising a square having a guide element secured on one side and projecting beyond one edgethereof and parallel with said edge, said guide element being connected tothe square for lateral angular movement with reference to that surface thereof which bears against the work.

3. A device for use in cutting the ends of power-belts and comprising a square having a guide element secured on one side and projecting beyond one edge thereof and parallel with said edge, said guide element being connected to the square for lateral angular movement with reference to that surface thereof which bears against the work, means to position saidguide element at right angles to said surface, and a foot iange projecting from said angularly-movable guide element to bear on the surface of the work and position the guide element at an oblique angle with reference to the work, substantially as described.

4. A device for use in cutting the ends of power-belts and comprising a square having a guide element secured on one side and projecting beyond one edge thereof and parallel with said edge, in combination with a cutter guided by said guide element, and a gage device carried by said cutter and coacting with said guide element, substantially as described.

5. A device for use in cutting the ends of power-belts and comprising a square having means to engage one edge of a belt, a guide element to direct a cutter across the belt, a guideway, a shoe movable therein, and a clamp to secure the square on the belt and connected to said movable shoe, substantially as described.

6. A device for use in cutting the ends of power-belts and comprising a square having a guide element to direct a cutter across a belt, a guideway, a shoe movable in the guideway, a clamp-yoke having one arm above and one arm below the square, and a screw in the upper clamp-yoke arm and swiveled to the shoe, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

FRANK M. LINDERMAN.
