COMBINED BENBING IvlirCHNE AND V Application led January 17, i922.

T o all whom t may concern.'

Be it known that I, CLARnNon S. GORDON, a citizen or" the United States, and resident ol Los Angeles, in the county of Los Angeles 5 and State ot' California, have invented new .and useful Improvements in CombinedBending Machines and Vises, of which the following is a speciiication.

This invention relates to bending machines, and more particularly to a form of bending machine and vise combined, wherein strips or pieces of metal of different sizes and shapes may be tightly held and bent to a required angle in a simple operation and 16 in an effective manner.

The primary object of my invention is to provide a bending machine of simple design and with a minimum number Vot parts, so held together that they may be 20 readily assembled and disassembled and arranged' to be supported on a worlr bench or table, as in the case of ordinary bench vises.

An object of my invention is to provide in a machine of the character mentioned, a

base adapted to be stationarily supported on a bench or table, and a. plurality of 'relatively adjustable forming blocks mounted on said base and provided with jaws for gripping strips or pieces of metal, and adapted I0 for clamping the strips or pieces of metal rigidly in position, one of said forming blocks being pivotally held Von said base and adapted to be swung thereon for bend'- ing the metal against the jaw of the other forming block. n

Another object is to provide in combination with a stationary base having a slidably adjustable forming block mounted thereon, another forming block pivotally and slidably mounted on said base, so that the jaws thereof may be disposed at any desiredangle with respect to the jaw of said other forming block, for the purpose of holding strips or piecesY of metal at any desired angle on the base, and capable of use as a vise when the movable forming Vblock is stationary held.

Still another object is to provide a stationary base having a screw operated forming block slidably held thereon, and a swivel forming block pivotally held thereon, and including relatively stationary and movable jaws forming a vise for gripping the strips or pieces of metal in a bending operation, or for the purposes of an ordinary vise.

Serial No. 529,979.

@ther minor and detailed objects of invention will appear as the description progresses. Referring now to the annexed drawings, in which l'liave shown a preferred embodinient of my invention, subject to modification within the scope of the appended claims:

Fig.` l0 is a perspective view of the swivel tor-ming block.

Fig. l1 is a perspective View of the vise body; and FiglQ is a fragmentary section oiE the base on line l2-l2 of Fig. 1.

A5 shown in the drawings, B represents base which has a horizontal web l, one portion ofwhich is rectangular, as at Z), and the remaining portion semi-circular, as at 7). The portion o has a semi-circular rib 2 extending above the surface of the web l, and the upper edge of said rib is adapted to be machined smooth for purposes hereinafter described.

The rectangular portion b of the base has a plurality of bores 3, 3, etc., formed therein and adapted t0 receive bolts 4, 4, for the purpose of holding the base stationarily on a table. or bench T. In the approximate center of the base B, l provide a boss 5 which is concentric with therib 2er the portion and is bored at 6 to receive a stud 7,

either integral with or iiXed to a corresponding boss 8 in the vise frame V, which is supported on the upper surface of the base B and is adapted to swing about the axis of the stud and over the upper smooth surface. et the rib 2. V

The stud 7 may have a. reduced threaded portion 9 on the lower en d thereof, so that a nut 10 may be threaded thereon below the boss 5 of the base, for holding the vise frame in position on the base. The vise V has an integral jaw J on'the inner end thereof and extending transversely across the vise, so that when the vise is positioned as shown in 1, the inner surface 10 of the jaw J will be disposed transversely ot the base B, The jaw J oli' the vise is preferably in two portions, one of which is higher than the other, and the inner corner 11 of the higher portion of said jaw is alined with the axis of the swivel stud 7 of the vise.

The vise V has an extension 12 of rectangular cross section which isdisposed at right angles to the body of the vise and is recessed to receive a bar H which constitutes a handle whereby the vise may be swung on its aXis Lover the rib 2 of the vise, and said vise also has an arcuate web 13 which connects the extension 12 and the vise body, and has its outer edge formed substantially flush with the outer edge of the rib 2 of the base and adapted to be moved over said rib, as shown in Figs. 1 and 2.

The extension 13 is provided with a hole 14 and the base B is provided with a pair or more of holes 14 with which the hole 14 of extension 13 is adapted to register, when the vise is positioned as shown in Fig. 1, or when extended to an acute angle relative to the base. The vise may thereafter be stationarily held on the base by inserting a bolt pin through the hole 14 and one of the holes 14 when the vise is to be used for ordinary purposes of such devices.

The vise body is provided with a longitudinal extension 15 of rectangular form and the upper portion thereof has guides 16, 16 formed thereon with a guideway 17 therebetween, which is adapted to receive ali-orming block F of slightly narrower width than the extension 15 of the vise. Said forming block has a jaw J termed on the inner end thereof and corresponding to the jaw J of the vise bodv.v The inner ysurface 18 of said jaw being parallel at all times with the sur- Vlace 10 of the yjaw J, so that the strip or piece of metal, as at W, may be held transversely in the vise betweenthe jaws J and J and clamped thereon by meanshereinafter described.'

The jaw J is braced against the base 19 of the forming block F by means of a rib 20 and a pair of spaced lugs 21, 21 are integrally formed ontbe block F andnear the forward end thereof, and depend down? wardly through a central opening 22 in the vise trame V.

The lu s 21, 21, are bored at 22 to receive a screw which has a reduced portion 23 j ournaled in a hole 24 in the outer end 25 of the vise `iframe, and is additionally j ournaled in a bearing 26 beneath the jaw J or" said vise. Said screw has an extension 27 extending rearwardly over and substantially beyond the rib 2 ot base B, and the rear end of said extension has a handle It pivotally held thereon and capable of extension to right angles with respect to the screw, so as to effect the turning of the screw in its bearings.

A nut N is threaded onto the screw S between the lugs 21, V21 of the block F and has a central portion 28, which extends upwardly into a recess inthe base 19 of said block and lateral extensions 29, 29 with diametrically alined surfaces 30, 30 thereon adapted to slidably engage guideways 31, 31, formed on the lower side of the vise frame V, as shown in Fig. 4.

Thus, it will be apparent that the turning of the screw S by means of the handle It will effect the corresponding movement of the nut N longitudinally of the vise trame, and

the nut N being held between the lugs 21, j

21, of the forming block F will correspondingly slide said block longitudinally on the vise frame V, so as to regulate the space between the jaws J and J of the vise and forming block respectively, for clamping the work V between said jaws.

It will be understood by reference to Fig. 1 that the inner edges of the jaws J and J are at all times parallel and longitudinally disposed on a line cutting the axis of the base, preparatory to a bending operation, and when the vise is moved for effecting the complete right angle bend, the inner edges of said jaws will he alined transversely or" the base on a line cutting the axis thereof.

A guideway 32 is formed on the rectangular portion of the base B, with guides 33, 33, at ythe sides thereot` :For slidably receiving a forming block F which is mounted on the upper surface of the base in a pla-ne slightly below the level of the block F on the vise. It will be noted that the blocks F and F have longitudinal recesses 32, 32, cut in the sides thereof and corresponding to the guideways 17 and 32 oithe vise and base respectively, in which said blocks are adapted to slide.

The forming block F has a jaw J1 on the inner end thereof and a gripping surtace 34 which is adapted to be alined with the surface 18 ot the block F, as shown in Fig. A1, and the inner edge of jaws J and J1 of blocks F and F are adapted te he substantially in abutting position, the jaw J1 ot block F being braced against the base 35 of Said block by means of a rib 36,

Block F has depending lugs 87, 37, thereon which correspond to the lugs 2l, 2l, of block F, and said lugs 37 are bored at 38 to receive a screw S corresponding in character to the screw S of the vise. The outer end of screw S is reduced at 39 and is journaled in the rib 40 of the base, while the portion 4l at the rib of said screw is jour naled in the transverse rib 42 ot said base.

The screw S also has an extension 43 which exends rearwardly through an opening 44 in the web 1 of the base, and is journaled in a boss 45 formed on said base, and is provided at its rear end with a. handle z. pivoted thereto and corresponding to the handle /z` on screw S. A nut N substantially similar to the nut N of the vise, is threaded to receive the screw S and is held between the lugs 37, 37 of the forming block F, so that when the screw S is turned the forming block F will be moved longitudinally on the base to an extent corresponding to the movement of the block F on the vise. The nut N has the lateral portions 29, 29 which engage guideways 46, 46 formed on the body of the base, as shown in Fig. 4, and serve to guide the nut in its movement thereover.

The ends 23 and 39 of the screws S and S are provided with cotter pins 47, 47 for preventing the withdrawal ot the screws from their bearings.

Now, in operation the vise V is positioned with respect to the forming block F and the base B, as sho-wn in Fig. l. The blocks F and F" are adjusted by means ot the screws S and S respectively, so as to be alined transversely of the base and in spaced relation to the jaw J of the vise, the work lV which is to be bent is then placed in position by the jaws J and J of the vise and against the jaw J1 of the block F, whereupon 'the screws S and S are turned vfor tightly gripping the work between the adjacent surface of the jaws. Thereafter the vise V may be swung in a clock-wise direction on the base and over the rib 2 thereof by means of the handle H, to any extent up to and including a right angle for the 'torni ot' device shown in the drawings. ln lsuch case the portion of the work W which gripped between the jaws J and J will be bent at an angle relative to the portion which abuts the jaw Jl, thereafter the screws S and S may be turned for looseningl and removing the work l from the vise.

lt will be understood in this connection that the jaws oit the forming blocks may be so formed and the machine so devised as to permit the turning of the vise on the base so to make bends of greater extent than 90 degrees, `but in the drawings l have shown device arranged only for making bends up to and including 90 degrees.

When the work is removed from the vise, the vise may be restored to normal position and other strips or pieces of metal inserted successively tor other operations, and said operations are performed in a like manner.

In the event that the machine isto be used for ordinary purposes of a vise, the screw S may be operated for removing the block F, so as to clear the Work, and the work may be gripped between the jaws J an J ot the vise proper. ln such case, a bolt or pin may be inserted through the holes 14 and 14 or" the vise and base respectively7 `for holding the vise immovable on the base while the vise is being so used.

It will be observed that the vise may be turned to an acute angle on the base so as to be more convenient and accessible for the reception of certain kinds of work, and to better clear the forming block F.
