To all whom t may concern:

Be it known that I, ELMER E. SANBORN, a citizen of the United States, and a resident of Lynn, in the county of Essex and State of Massachusetts, have invented an Improvement in Binding-Nicking Machines, of which the following description, in connection with the accompanying drawing, is a specification, like reference characters on the drawing representing' like parts.

rlhis invention relates to a machine for cutting or nicking a strip of binding material, such as the ordinary metallic binding employed in binding the edges of shoe pat tei-ns and similar articles, so that the binding may readily be bent and fitted around a corner.

lt is the object of the invention also to cut or nick the binding while it is being applied to the edge of the article to be bound, and to place the out or nick at exactly the right point, so that when the binding is bent around the corner it will fit and conform eX- actly to the edge of the article to be bound.

The machine of this invention is designed primarily for use in the work of binding shoe patterns with a narrow strip of brass, but it is obvious that it may be used in any other connection where work of generally similar character is to be performed.

The nature of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

The drawings represent the preferred embodiment of the invention in a machine for cutting or nicking the bindings of shoe patterns.

In the drawings, Figure l is a side elevation of the machine. Fig. 2 is a top plan view. Fig. 3 is a front end elevation partly in cross-section. Fig. 4t is a view of one corner of an article, such as a shoe pattern, showing the binding in position after cutting or nicking and before bending around the corner. Fig. 5 is a view similar to F ig. a showing the binding bent around the corner. Fig. 6 is a detail view in side elevation, partially in cross section, to show the position of the cutting and gaging elements. Fig. 7 is a detail in side elevation to show the position of the guide nger.

rlhe machine is shown as comprising a heavy and powerful frame or standard presenting a somewhat elongated base and correspondingly elongated overhanging arm,

with the cutters mounted at the end of the base and overhanging arm, thus permitting the work being bound to swing in between the base and overhanging arm.

The machine may be operated in any suitable manner by hand or foot or by power, but is herein illustrated as designed to be operated by power. It is controlled by a clutch mechanism providing a single operation of the machine after the clutch is released, but by holding the clutch operating mechanism out of operation and continuing the application of the power the machine will run continuously, making one cut at each revolution.

The heavy frame or standard'of the machine is indicated at A. This standard is hollow and comprises the lower forwardly projecting elongated base portion A2, with the corresponding overhanging arm A3. These parts are made heavy of cast-iron and the frame or standard may be bolted in place to a table or other support by means of the lugs provided at A4.

The main driving shaft B passes transversely through the frame A, and carries at one side thereof a loose pulley B2 driven from any suitable source of power. A rotary clutch member B3 is mounted on the shaft B, and when moved toward the pulley ,B2 serves to lock the pulley to the shaft, and

when moved away from the pulley allows it to run free on the shaft. The spring B4, the strength of which is controlled by the adjustable nut B5, serves to move the clutch member B2 toward the pulley. A second shaft C is mounted in the frame A back of and parallel with the shaft B, and carries at one end a clutch arm C2. The shaft C is normally turned to cause the clutch arm C2 to engage the clutch member B3 by means of a rearwardly projecting arm C3, connected at its ends to the machine frame by a spring G4. AThe shaft C is moved to raise the clutch arm C2 by means of a rod C5 depending from the arm C3 and operated in any suitable manner, as by means of a foot lever.

The clutch member B3 has a cam groove BG therein, and the end of the clutch arm C2 is cam shaped to cooperate with said groove, the construction being such that when the clutch arm C2 rests upon the clutch member B3 under the iniiuence of the spring C4 the end of the arm C2 will drop into the cam groove BG at the proper period of rotation of the shaft B, and shift the clutch member ilo binding.

B3 on the shaft away from the pulley, thus stopping the machine. The cam groove is so arranged that the machine is stopped after one complete revolution.

In order to prevent the parts being carried out of position by their momentum a suitable brake mechanism is provided, herein shown as a friction band D, pivoted at D2, and having its ends adjustably and yieldingly connected at D2. A friction wheel is carried on the shaft B between the members of the friction band D. There being nothing novel in this brake mechanism it need not be further illustrated or described.

The cutting or nicking operation in both edges of the binding is performed simultaneously, and for this purpose two cutting mechanisms are necessary. In the construction illustrated each cutting instrumentality i comprises a fixed cutter and a movable coperating cutter. The two fixed members are herein shown as united in a single cutter block, while the movable cutters are shown as pivotally mounted one above and one below the cutter block to cooperate therewith.

The upper surface A5 of the forwardly projecting base A2 of the machine frame is provided with a bed-plate E, upon which the work being bound is adapted to be supported and turned. This bed-plate E is apertured or open at its central portion E2, and is provided on its upper surface with a recess E2, adapted to receive the bound edge of the article so that the article may lie fiat upon the bed-plate. The cutter block F is secured by means of screws F2 to a projection E* from the bed-plate, and is arranged to present its cutting face over the aperture E2 near the center of the bed-plate.

The cutting block F presents a V-shaped notch at its upper and lower surface, the front edges of the notch in each instance being cutting edges, and the angle of the notch being the angle of the nick to be cut in the The cutter block on its front face is also grooved transversely between its notched cutting edges, as indicated at F2, to receive and position the folded edge of the binding. The upper and lower cutters are both preferably constructed, mounted and operated in the same manner, so that but one need be described,

The projecting base A2 and overlianging arm A2 are each provided at their forward ends with bracket plates AG and A7, re-

spectively, bolted thereto by means of the bolts AS, and the cutters are mounted respectively in these bracket plates. The bracket plate in each instance is provided with forwardly projecting bearings A2. A shaft or pin G is mounted at one end in the bearing A9 and at its opposite end in a thimble G2, and carries between the end of the thimble G2 and a shoulder G3 a rotatable sleeve Gt. The thimble G2 is screwthreaded into the bearing A2 and the end of the shaft is provided with locking nuts G5.

A cutter head H is mounted upon and made fast-to an eccentric portion of the sleeve G2 by means of the set-screw H2.

The cutting or nicking blade H, shown as of general segmental shape, fits over the eccentric portion of the sleeve G* against the cutter head H, and is locked in place by the nut H3 screw-threaded to the eccentric portion of the sleeve G2. A set-screw H4, provided with a locking nut H5, passes through a projection of the cutter head and bears against the cutting or nicking blade H2. Each cutter head H has a pivotal connection HT with the arms of a U-shaped link K, eX- tending through the base and overhanging arm. This link K near its middle portion is pivotally connected at K2 with a bellcrank lever K3, fulcrumed at KL in the frame, and pivotally connected at K5 with an eccentric strap K, operated by an eccen-.

tric KT on the main shaft B.

The cutting edge of the cutting or nicking blades HG is V-shaped to correspond exactly with the V-shaped notches in the cutter block F, so that in coperation therewith a V-shaped nick will be cut from the opposite edges of the binding. The periphery of these blades HG is also formed on an arc having its center at the axis of the pivotal movement of the blades. Hence the blades may be sharpened at any time by simply grinding the cutting face back, maintaining the radial angle.

Tt will be seen that by the construction already described an accurate means of adjusting the movable or pivoted cutting or nicking blades HG vertically, laterally and rotarily or longitudinally is provided, so that the cutting edge may be brought at all times into eXact coperation with the notch in the cutter block. The vertical adjustment is secured by means of the eccentric portion of the sleeve Gt, for upon loosening the screw H2 the relative position of the cutter head and the eccentric may be changed, thus raising and lowering the cutting blade. The lateral adjustment is secured by means of the thimble G2, and' the rotary or longitudinal adjustment is secured by means of the set-screw H2.

The guiding finger M is pivotally mounted on the lower sleeve G4 with its guiding point projecting in front of the middle of the cutter block F and in such position that when the edge of the article to be bound abuts against the guiding point the binding will be placed in the proper position for cutting or nicking. This guiding finger is normally thrown out of the way of the nicking instrumentalities by means of a spring M2, connected therewith and at its other end to a hook N3 projecting from the bed-plate, and it is thrown up into position when it is desired to position the article by means of a handle Mt.

1n Figs. A and 5 is represented the corner of an article, such as a shoe pattern P, to be bound. The binding shown in cross section at Fig. 7 is composed of a flat strip of metal l, bent into general Ll-shape. This binding is pressed in any suitable manner on to the edge of the article l), so as to be firmly secured thereto. `When a corner is arrived at the binding is left projecting straight and then by means of this machine the nicks P3 are cut. at the corner. rlhe projecting portion of the binding is then turned about the corner on to the edge and pressed into position, as shown in Fig. 5.

The operation or" the machine will be apparent from the foregoing description. After the pivoted or movable cutters have been adjusted so as to coperate properly with the cutting edges of the cutter' block the machine is ready for operation. rlhe article to be bound being in the stage illustrated in Fig. lbut without the notches P, is placed upon the bed-plate E with the binding resting in the groove E, and with its rear or curved edge resting against the groove F3 in the cutter block, as shown in Fig. T. The operator then seizes the handle M* and throws the guiding finger M up against the binding, pressing it against the cutter block F, and moves the article P along until its edge 1)* comes against the guiding linger M. The article is then in proper position for cutting. rlhe handle llll is then released, and the rod C5 depressed, as by the foot of the operator. The depression of' the rod C5 raises the clutch arm C2, and clutch member B3 under the influence of the spring B* at once locks thepulley B2 to the shaft B. rllie machine is set in operation and through the intermediate mechanism fully described the pivoted or movable cutting' or nicking blades HG are swung down simultaneously so that their cutting edges catch under the edges of the binding, press the edges of the binding up against the cutter'block F, and pass through the binding simultaneously forming Athe nicks P3 in opposite edges of the binding. Meanwhile the clutch arm C2, unless it has been held elevated by continued depression of the rod C5, falls back on the clutch member BfI under the influence of the spring Ct, drops into the cam groove BG and upon the completion of one rotation of the shatt B moves outwardly the clutch member B3, unclutching the pulley B2, and the machine comes to rest.
