METAL-BENDING DEVICE.
Specification of Letters Patent.
Application filed December 20, 1910. Serial No. 598,303.
To all whom it may concern:
Be it known that I, ROBERT FISHER, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Metal-Bending Devices, of which the following is a specification.
This invention relates to metal bending devices of the sort particularly well adapted for bending or shaping rods or strips.
One of the objects of the invent-ion is to provide a device of the sort referred to which is particularly compact in structure and powerful and eflicient in action.
Another object is to provide such a device with an adjustable horn or anvil, adapting the machine for use in connection with different thicknesses of material.
Other objects and aims of the invention, more or less broad than those stated above, will be in part obvious and in part specifically referred to in the course of the following description.
The invent-ion consists of the elements, combinations, arrangements of parts, and applications of principles, all as will be hereinafter fully set forth; and the scope of protection contemplated will be indicated in the appended claims.
In the accompanying drawings, which are to be taken as a part of this specification, and in which I have shown merely preferred forms of embodiment of the invention: Figure 1 is a top plan view of a machine including the invention; Fig. 2 is an elevation of the subject-matter of Fig. 1; Fig. 3is a section on the line 3-3 of Fig. 1, looking in the direction of the arrows; Fig. 4 is a view, partly in section and partly in plan, of a modified form of the device shown in Fig. 1, and indicating by dotted lines the hook forming operation of the machine. Fig. 5 is a view of a modified form of device; Fig. 6 is a View at right angles to Fig. 5; Fig. 7 is a view similar to Fig. 4, but including a modified form of bending member; Fig. 8 is a view similar to Fig. 7, but with the operating parts in another position; and Fig. 9 is an end view of the modilied form of bending member.
Referring to the numerals on the drawings, and particularly to Figs. 1 to 4 inclusive, 1 indicates the base of my machine, from which rises an integral standard 2, having two plane surfaces 4 and 5 substantially at right angles to each other. The standard 2 is provided with apertures 6 extending therethrough and through the base, and a plate 7 is held rigidly upon the top of the standard as by means of bolts 8 extending through the plate and aperture 6. Opposite the face 5 of standard 2 rlses another integral standard 9, which with its appurtenant members, constitutes the horn of the machine. A movable bending member, indicated at 10, has right angled plane surfaces 11 and 12, and a handle 13, and is pivoted as by means of trunnions 14 integral with the bending member on either side of its bending surfaces 11 and 12, in the base 1 and plate 7 The relation of the movable member 10 to the standard 2 is shown in Fig. 4, the apex of the angle between surfaces 11 and 12 being in the line of surface 5 of the standard, and the bearings of member 10 being at either side of the effective width of standard 9. Preferably the face 12 of the movable bending member is provided with an antifrict-ion roller 30, which turns within a cavity 31 in said face upon a pin 32, extending through the end walls of the cavity. The purpose of this anti-friction element is to make the bending operation smooth and free from slipping and consequent shock and strain. Standard 9 is substantially rectangular in cross-section, having two oppositefaces parallel to face 5 of standard 2, and is pierced by a horizontal slot 16, through which passes a bolt 17, by means of which slotted spacing blocks 18 and a horn proper 19 may be held rigidly Patented J ly 23, 1912.
secured to the standard 9, the bolt passing-- through the slots of the spacing blocks, and being threaded into the horn. The relative arrangement of parts is preferably as shown in Figs. 1 and 4, so that the distance between surface 5 of standard 2 and the adjacent face of standard 9 is equal to the distance between the horn and the surface 12 of the movable bending member when the latter is in the position of Figs. 1 and 4. The spacing blocks 18 comprise right angled strips of different thicknesses, covering adjacent faces of standard 9 and overlying each other as shown, with the apexes of their angles in a line toward the pivot-a1 center of the movable member 10. Some of the spacing blocks, indicated at 20, may be fitted to cover the other adjacent faces of standard 9. Horn 19 is preferably shaped as shown,
so that a strip may be bent at an acute angle if desired.
It will be evident that in adapting the machine for use upon difiierent thicknesses of material it is necessary only to arrange the spacing blocks 18 and 20 accordingly. The blocks being of different thicknesses, and. the blocks determining the distance between horn 19 and surface 5 of standard 2 and the pivotal center of member 10, it is evident that upon removing one or more of the blocks 18 and adjusting the horn upon the blocks beneath it or upon standard 9, the distance between the horn and the surface 5 and the pivotal center of the member 10 will be increased, but equally. As the blocks are taken from between standard 9 and the horn they may be inserted between the bolt head and the other side of the standard, as indicated at 20. Thus the bolt will not project at any time beyond the face of the horn. The making of the blocks of different thicknesses is important, because by combining them in an obvious manner I am able to make the proper adjustments for bending many varying thicknesses of metal.
The use of the device as thus far described will be clear. The device being adjusted for the thickness of metal to be operated on, member 10 is brought to a position at right angles to that shown in Figs. 1 and 4t, that is, with the surface 12 in alinement with surface 5, and the rod or strip to be bent inserted between the standard 2 and horn l9 and opposed to member 10. Movement of the latter toward the rod or strip will bend the same to the extent of the movement of member 10. If it be desired to continue the bend thus made into a hook, the rod or strip may be placed as shown in Fig. l, resting against the face at of standard 2, and with its bent part resting upon the face 11 of member 10. Movement of member 10 as indicated in dotted lines in Fig. 4 will result in the formation of a hook. In order to provide for thus forming hooks with different degrees of curvature I may provide upon the face 4 of standard 2 a block 2d, secured as shown. Obviously by employing blocks of different thicknesses, the distance between the effective face of standard 2 and the pivotal center of member 10 may be varied, to the attainment of the object referred to.
In Figs. 5 and 6, I have shown a slightly modified form of device. Here the movable member 10 is pivoted to the base at one side of the horn (Fig. 6), instead of having bearings at opposite sides of the horn, and has a bending jaw 25 cooperating with the horn. The horn in this case is supported upon a member 26 integral with the base, and adjusted so that it may be at different distances from the fired jaw 27, also integral with the base, and from the pivotal center of member 10, by arranging the interposed spacing blocks, as in the case of the machine already described.
In using the device, the rod or strip is inserted between the horn and jaw 27, and opposed to the pivoted jaw the latter being of course first moved to the position where its bearing face 28 is in line with the face of jaw 27. Movement of jaw 25 Will bend the metal as already explained.
As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying d =awings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which. as a matter of language, might be said. to fall therebetween.
