In the following description similar characters This bracket is secured to the legs of the stand 5 of reference indicate like parts in the several figby means of rivets 3| passing transversely through ures of the drawings. the flange 28 of the bracket and the adjacent In its general organization this multiple tool or parts of the legs 2i and 23, as best shown in Figs. apparatus comprises a stationary stand, means 1, 4 and 6. The upper surface of the table or for clamping a wire, rod or the like and holding anvil 30 has its

opposite ends

32, 33 arranged horthe same in place while forming a screw thread izontally in line, and intermediate of these horizontal surfaces this table or anvil is provided with a recess or notch 34 which is of V-shaped form and has its sides preferably arranged at right angles to one another, as shown in Fig. 2. A bending jaw 35 having a right angle V-shaped face 35 for cooperation with the'notch 34 is arranged above the anvil 30 so that upon placing a sheet metal strip, similar to the strip 31 in Fig. 9, upon the table 34 and forcing the jaw 35 downwardly against this strip, the latter-will be bent so that two

parts

35, 39 will be arranged at right angles to each other, as shown by full lines in Fig. 10.

It will be noted that the anvil or table 35 pro,- jects outwardly from the frame, as shown'in Figs. 1 and 4, and the bending jaw 35 projects outwardly from the lever 44 and frame and over the anvil, as shown in Figs. .1 and 4, and is also comparatively narrow and short from its V- shaped underside or face and its upper side, as shown in Figs. 1, 2 and 4. By thus projecting the anvil and bending jaw from the frame and making the latter thin or narrow horizontallyv and short vertically it is possible to produce relatively short bends in wire and strips of metal and thus render the bending part of this apparatus particularly well suited for use by boys in making parts for small models while engaged in manual training. For example, as shown by dotted lines in Fig. 2, the end 39! of a metal strip has been bent so as to form a square loop which completely surrounds the bending jaw 35 without interfering with the operation of making the three bends in the strip necessary to form this loop.

For the purpose of enabling thishandle and the bending jaw 35 to be also utilized for bending wire rods into angular form the underside of the jaw 35 is provided with a transverse notch 45 which is adapted to receive the upper side of a wire rod which is to be bent. Upon placing a straight wire rod, such as that shown at 4| in Fig. 7, upon the

horizontal surfaces

32, 33 of the anvil 3D and moving the jaw 35 downwardly with the notch 40 thereof in engagement with the upper side of the wire rod, the latter will be bent between the cooperating V-

shaped surfaces

35 and 34 of the bending jaw and anvil into the angular form shown in Fig. 8, in which the two

parts

42, 43 of this rod are arranged at right angles to each other.

This bending jaw is arranged on one part of a rocking lever 44 which is arranged between the upper parts of the legs of the stand and is pivotally mounted thereon so as to turn in a vertical plane by means of a pivot bolt 45 passing through this rock lever and the adjacent parts of the stand legs 2t, 23 as shown in Figs. 4 and 5.

A rocking motion is imparted to this lever by means of an eccentric or cam 45 which is arranged between the upper ends of the stand legs and engages one of its flat sides with the inner I side of the leg 2| while its .periphery engages with opposite sides 41 of a notch 43 formed in the upper part of the rocking lever. This eccentric or cam is rotated by means of a hand lever 49 which is arranged between the eccentric or cam 45 and the opposite upper part 25 of the other stand leg, and this cam or eccentric and the hand lever 45 are pivotally mounted on the stand by means of a pin 50 passing through the cam, hand lever and the upper parts of the stand legs, as best shown in Figs. 4 and 5.

Connection between the cam and the hand lever 49 may be effected in various ways, for example by means of a pin passing transversely through the same.

On that end of the apparatus opposite to that on which the bending anvil 39 and bending jaw 35 are located, the apparatus is provided with means for cutting and perforating strips of sheet metal and the like. These last-mentioned means include an L-shaped bracket having an upright plate 52 secured to the outer side of the stand leg 2 I. by means of rivets 53 and a horizontal plate 54 extending from the upper end of the vertical plate 52 over the undersides 55, 55 of recesses 51, 55 formed in the upper parts of the vertical faces of the stand legs, and thereby serve as a table for supporting sheet metal strips or the like which are to be perforated. This table is provided with a die opening 59 which is adapted to receive a vertically movable punch or tool 55 for producing perforations 5| in the strips of metal, shown in Figs. 9 and 10, by placing these strips or similar articles on the die table 5.4 and forcing the punch or tool 55 downwardly against this strip of metal and into the die opening 59. The material removed from the strip of metal at this time passes downwardly into the space between the legs of the stand and then escapes downwardly therefrom, where it can be disposed of in any suitable manner.

This punch or perforating tool 60 is mounted on the underside of a rocking arm-'62 on the adjacent part of the rock lever 44 opposite to the bending jaw 35, as best shown in Fig. 4, so that upon oscillating the hand lever 49 and the cam 45 a rocking motion will be imparted to the punch in unison with the bending jaw 35 which are mounted on opposite sides of the rock lever 44.

For convenience in spacing the holes in a strip of metal which is to be perforated uniform distances apart, the die table- 54 is provided on one side of the punch opening 53 with a gage opening 53 which is spaced from the punch opening 59 a distance equal to that which is desirable to space apart the openings in the strip of metal.

In using this punching device for producing a row of perforations which are spaced equal distances apart, the hole is first punched in the strip by means of the punch 50 and die opening 59 and then this strip is advanced so that the opening just formed therein is in line with the gage opening 53, after which a pin is inserted through this first opening of the strip and the gage opening 63, and thereby hold the strip in the properly spaced position for forming'the next opening in the strip. This gaging operation is repeated for each additional opening of the row which is to be formed in the strip and thereby enables successive openings to be properly spaced and permits of producing an accurate product in which the strip forms a part.

For the purpose of permitting the strip of metal to be gaged laterally so that the perforations which are formed therein are arranged at the desired distance from one of the longitudinal edges of the strip, a gage may be employed similar -6 to that which is shown in Figs. 1, 2, 3 and 5, which preferably consists of a horizontal longitudinally slidable plate 54 which is provided with a longitudinal slot 55 receiving the pivot bolt 45 and adapted to be clamped between the nut 55 of this bolt and the outer side of the stand leg 2|, and provided at one end with a gage lug 51 extending across the gap formed by the notch 51, and also provided with a finger piece 53 for shifting this gage plate.

By adjusting the plate 54 so that its gage lug 41 is in the desired position lengthwise of the gap 51 it is then possible to place the strip to be perforated against this gage while producing perforations therein and insure locating these perforations at the proper distance from the longitudinal edges thereof.

For the purpose of cutting wires by means of this tool the arm 62 of the rock lever 54 is provided with an opening 69 which is adapted to cooperate with an opening III in the stand leg 2|, so that these parts form the blades of a shearing device whereby wire may be cut by first passimg the latter through the openings 59 and 10 while they are in line with each other, and then rocking the lever 44 relative to the stand. It is also possible to cut strips of metal or the like into various lengths by inserting the same in radial cutting slots II and 12 formed respectively on the blade arm 52 of the rock lever 44 and the adjacent part of the stand leg 2|, while these cutting slots are in line with each other, and then rocking the lever 44 so that these parts slide by one another in the manner of a pair of shears, thereby severing the respective strip.

In order to thus permit of utilizing only the leg 2| of the stand as a part of the shearing or cuttirm mechanism to the exclusion of the other leg 23 of the stand, the upper part of the leg 23 is cut back, as shown by dotted lines 13 in Fig. 4, so that the same does not interfere with the operation of cutting either a wire or a strip of metal as above described.

For the purpose of enabling the position of a wire rod or strip of metal which is to be cut, bent or perforated to be properly positioned relatively lengthwise to the cutting bending and perforating mechanism, gage means are provided which in their preferred construction include an upright gage arm 14 which is adapted to extend across the path of the wire rod or strip of metal which is to be operated upon, and also capable of being adjusted transversely relative to the stand to suit the length of wire or strip which is required.

For this purpose the gage arm 14 is arranged at one end of an adjusting rod I5 which extends transversely through corresponding openings formed in the lower parts of the stand legs 2|, 23. By sliding the gage rod 15 lengthwise through the stand legs the gage arm 14 may be shifted lengthwise toward and from the wire and strip cutting, bending and perforating mechanism to suit the length of the articles which is required, and by turning the gage rod I5 in the stand legs the gage arm 14 may be brought into line with either the cutting openings 59 and 10 for severing wire or rods, or into line with the cutting slots H and 12 for severing strips of metal or in line with the bending mechanism or in line with the perforating mechanism at the desired place.

After adjustment of the gage arm 14 in the manner described the same is positively held in the required position by clamping means which, as shown in Figs. 1, 3, 4 and 6 preferably consist of a bolt having its inner part arranged in the space between the lower parts of the stand legs and provided with an eye 16 which receives the gage rod 15 while its shank 11 extends laterally beyond the adjacent vertical edges of the stand legs, and a clamping screw nut 18 arranged on the thread of the bolt shank 11 and bears against the outer side of the vertical plate 52 of the punching bracket.

Upon loosening the nut 18 the grip of the eye It on the gage rod 15 is'released, thereby permitting the latter to be shifted lengthwise and also rotated for bringing the gage arm 14 into the desired position with reference to the wire and strip cutting bending or perforating mechanism, and upon tightening this nut the eye of the bolt will be drawn against the gage rod 15, thereby clamping the same in position on the stand so that the gage arm 14 will be retained in whatever position it has been adjusted.

For the purpose of enabling wires or rods similar to those shown in Figs. 7 and 8 to be provided at their ends with external screw threads 19 means are provided on this apparatus for gripping such wires and holding the same in place while a die is engaged either by hand or otherwise with the end of the wire thus held for cutting a screw thread thereon.

In the preferred construction some of the members of the means for gaging the length of the wire or strip which is to be cut, and also members of the punching mechanism are utilized as means for holding the wires or rods while they are being provided with external screw threads. This is preferably accomplished by providing the outer edge of the vertical plate 52 of the punching bracket and the corresponding edges of the stand legs 2! and 23 with V-shaped notches 80, 8|, as shown in Figs. 1, 4 and 6, which notches together form a V-shaped seat for engagement with the inner side of a wire or rod while the outer side thereof is engaged by the adjacent inner part of the clamping nuts 18 and thereby securely grip a rod or wire and hold. the same reliably in place while a screw threading die is being rotated in engagement with an end of the wire for producing a screw thread thereon.

For convenience in locating the gage arm 14 with reference to the cutting mechanism, the gage rod 15 is provided with a measuring scale of graduations. such as those indicated at 82, which latter may be associated with the adjacent part or surface of the stand in order to conveniently predetermine the location of the gage arm 14 before beginning the operation of cutting the bars or strips of metal into the required lengths.

This eye-bolt and its nut therefore serve as part of the means whereby the longitudinal gage for the wire and metal strip are held in place and also as part of the means for holding a wire or rod on the stand while threads are being cut thereon.

As 'a whole this multiple tool apparatus is comparatively simple in construction, considering the various functions which the same is capable of performing, the same is compact in its organization and it is also strong and durable and not liable to get out of order even though the same is subjected to heavy work.

Moreover the several parts of the same are all of simple construction and capable of being made mainly of sheet metal stock, thereby enabling this apparatus to be constructed at comparatively low cost so that the same is Well-suited for use in manual training of boys who follow mechanical pursuits.
