.The invention relates to machines for bonding and upsetting metals, and has for its object to provide means whereby either of the operations may be performed separately or simultaneously, as desired.

The invention has for its further object to increase the scope of'these machines, whereby they are adapted to bend or upset or perform both operations on metals having various forms in cross-section-such as round, semi- I cylindrical, square, oval, or L, T, or double- T shaped-and to produce a compact and efficient machine that is readily operated.

To tgiese ends the'invention consists in the combination, with a stationary carrier, a rotatable carrier, and sector-shaped shaping- 'blocks secured thereto, of gripping-levers for securing the metal to be operated upon to said blocks, substantially as hereinafter fully described.

The invention further consists in the combination, with a rotatable carrier, a carrier having a rectilinear movement toward and from said rotatable carrier, and sector-shaped shaping-blocks secured thereto, of grippinglevers for securing the metal to be operated upon to said blocks, substantially as hereinafter fully described.

The invention further consists in the'combination, with a rotatable carrier, a carrier having a rectilinear. movement toward and from said rotatable carrier, sector-shaped shaping blocks secured thereto,.and grippinglevers for securing the material to the blocks, of locking devices whereby either of the carriers may be locked against movement, substantially as hereinafter fully described.

The machine is composed, essentially, of two working sections or carriers,A B. Of these one may be stationary and the other movable, as

in Figs. 1 and 2, or one of said carriers may have a rotary and the other a rectilinear mo tion, as in Figs. 3 to 7.

As shown in, Fig. 2, the upper portion or head of the carriers A and B has the form of a sector, the carrier A being pivoted to the carrier B by means of a central pivot, I, and the carrier B is securely fastened to a supporting-blg ck,B gof,wood or other material; or said carrier B or the'block B may be const-ructed so as to be secured in a bench or other vise when used for bending small articles of metal. 1

A and B are two wedge or sector shaped shaping-blocks secured, respectively, to the carriers A and B, the opposite vertical faces of which blocks are roughened or serrated or provided with teeth.

a a and b b are holes or recesses formed, respectively,in the headsof the carriers A and B for the reception of gripping-levers O,between which and the'bloeks A and B the metal to be bent or upset is securely held, as shown in Fig. 2. The holes or recesses a and b are formed at different distances from the axis of rotation of the carrier A, and upon a circle concentric therewith, so as to accommodate bars or beams of metal of varying diameter, as will be readilyunderstood. The carrier A is also provided with sockets or holes ain the periphery of the head thereof for the reception of an operating-lever, If, by means of which said carrier is rotated either toward the right or left on the section B.

The operation of this machine is as follows:

The carrier A is rotated until the shapingbloeks A B are brought to a position with one of their serrated faces on the same diametral line. The bar of iron to be bent is then clamped by means of the gripping-levers to said bloeks,and the carrier A rotated by means of the lever L to bend the bar, as shown in Fig. 2. If it is desired to upset the end of a bar or piece of metal, it is clamped to one of the blocks with its end that is to be upsetlying in the space between the two blocl s,and an upsetting-block is clamped to the other shapingbloek, so that when the carrier A is rotated, the upsetting-block, clamped to the shaping-block A thereof, will upset the end of the bar, as hereinafter referred to. In this operation the upsetting-block is preferably clamped to the block A of the rotatable carrier A,and the bar of iron to be upset to the block B of section 13, though this is not absolutely necessary.

Although two gri pping-levers are preferably used, this is not absolutely necessary, as one such lever will answer the purpose, especially when the machine is constructed for bending light rods, rails, &cl

In case there should be difficulty in rcmoving the bent bar from the machine-or,in other words, in disengaging the grippinglevers therefrom by reason of their serrated surfaces and those of the blocks A B sinking too deep into the metal-the block A or that B, or both, are connected with their respective section by means of a pin and key, so as to readily detach the same therefrom; and to prevent the accidental displacement of the blocks on their sections, they may be seated in recesses (1 N, Fig. (i.

To increase the scope of the machine as well as its efficiency, it may be constructed as shown in Figs. 3 to 7.

E E is the frame, the right-hand base portion E of which is bowl-shaped and has a hearing for the hinge pintle or pivot P and an annular flange, 0, provided with a series of holes, 0, and also a bearing for one end of an inclined shaft, G, whose other end has its hearing in a cross-piece at the left end of the frame of the machine. This shaft carries at the lower end a bevel-pinion, g, and at its upper end a segmental bevel-wheel, 9, that meshes with a bevel-pinion, g ,on the short shaft S, that also carries a fly-wheel, F, provided with a handle,

f, for rotating the same. The frame E has two arms, E, that project over the base E, said arms being perforated for the reception of the pivot-shaft P, by means of which the carrier A is hinged or pivoted to said frame-arms. The carrier B in this construction of the machine is slotted and capable of sliding toward and from the carrier A on the arms E of the frame E, from which said carrier 13 is also sup ported. On the lower end of the pivot-shaft l is mounted a bevel-wheel, H, that meshes with the pinion g on shaft G, and from which pinion said wheel is rotated. In the upper face the wheel H has a series of holes, h, corresponding in number with the number of holes a in the base-flange e of frame E. The carriers A B are here also provided with shaping-blocks A B and grippinglevers O, .forsecuring the material to be operated upon to said blocks A B, and a a and Z) Z) are theholes in the heads of the carriers for the reception of the pins or pivots of the said gripping-le-- vers, in which holes said'pivots fit loosely, the levers being shifted from one side of the blocks to the other, according to the side operated with, or when both sides of the blocks are alternately used for bending or upsetting, or both, a bar being applied to one side of the blocks while the bar previously operated upon by the opposite faces of the blocks is being removed.

M is an arm projecting from the rotatable section A. It has four holes, or m and m m. The holes in m register with the holes h in the upper face of the wheel H, and the holes at m register with the holesc in the flangee of the base E of frame E, for purposes presently explained.

A rectilinear movement is imparted to the carrier B of the machine by the following instrninentalities: K is a lever fnlcrnmed at 7. upon the upper arm, E of the frame E, and said lever is pivoted to the upper end of carrier B, the piv0t-pin 6" having the necessary play in a slot, 7:, of lever K. The said lever has a slot-ted projection, It", in the slot of which plays a pivot-pin, Z, at one end of a lever, L, that is fnlerumed at 12 upon the lower arm, E of frame E, the opposite end of said lever L being pivoted to the lower end of carrier 13 at I). A lover, I, pivoted upon the pivotshaft P, has a number of holes, 1', and two holes, t i. The hole '5 registers with the holes or sockets h in the face of the wheel H, and the hole t" with those 0 in the flange 6 of the base E of frame E. The lover I is connected with the lower end of the lever K by means ofa link, J, Figs. 3 and 7.

It is obvious that when the lever I is locked by means of an eyebolt or pin, 1, to the wheel H, and that when said wheel is rotated in the direction of the arrow a", Figs. 4, 6, and 7, the lower end of lever K will be thrown outward or toward the left, thus moving inwardly or toward the right at its upper end above the fulcrum 70. At the same time the end of lever L, above its fulcrum I, is also carried outward or toward the left, while the end below the fulcrum Z is carried inward or toward the right,

thereby moving the section B in a rectilinear direction toward the carrier A.

When it is desired to simply bend a bar of metal without upsetting the same, the arm M of the rotatable carrier is connected with the wheel H by means of a locking bolt or pin, M, Fig. 7, and it'is evident that if said wheel is rotated by the mechanism described the section A will rotate therewith,while the section Bwill remain stationary, the lever I being disconnected from wheel H, and connected with the base-flange e of frame E'by means of thelocking bolt or pin I. When, on the other hand, it is desired to upset a bar of metal, then the lever I is rigidly connected with the wheel H,and the arm M with the base-flangee offrame E. Finally, if it is desired to bend andupset a bar of metal, then the lever I and arm M are both locked to the wheel H, asjwill be readily understood. By means of the holes e inthe flange e'of the base E and the holes h in the upper face of the wheel H, any desired position may be given to the rotatable carrier A relatively to the sliding carrier B. The amplitude of the rectilinear movement of the carrier B may be varied within certain limits, for which purpose the lever I is provided with a number of holes, 43, as above stated, .to vary the point of connection between it and the" arm or link J, that connects levers H I, and thereby vary the amplitude of the throw of said lever, as will be readily understood. It will also be seen that the lever I may be shifted from one side of the machine to the other, as may be found most convenient, and, if desired, the arm M, instead of forming an integral part with the section B, may be made of aseparate partand keyed to the pivotshaftP of the carrier B, the wheel H being in this case loosely mounted on said pivot, and means provided such as a clutch-coupling for connecting the wheelwith the shaft. The arm M, for instance, may also be connected with the pivotshaft by a feather or spline, so as to cause it to rotate therewith, but leave it free to slide vertically thereon, and may be provided with one half of a clutch-coupling, the other half of which may be formed with or secured to the wheel H, as will be readily understood.

These machines are adapted to impart a variety of forms to bars or beams of metal by means of the shaping blocks and auxiliary blocks or blocking-bars.

In Fig. 8 we have shown .the operation of forming a counter-bend in a bar of iron, the block A of the movable carrier A being removed and a blocking'bar, a, employed in its stead, in conjunction with a second bar, a, the end of which, in conjunction with the block B, forms the counter-bend, as shown. It is obvious that the extent of the bend will depend upon the width of the end of bara, that abuts against the bar to be bent.

In Figs. 9 and. '10 we have illustrated the means for forming a crank in a bar or rod of metal by means of blocking-bars a a, one of the latter being placed under the bar to be bent whenever the thickness thereof is less than the height of the shaping-block.

In Fig. 11 we have illustrated the means for upsetting a bar of metal and imparting to the upset end. thereof any desired form by means of upsetting-blocks a, the upsetting end 0t which has the form intended to be given to the upset end of thebar. In'this case both blocks A and B are brought into use.

In Fig. 12 we have shown the manner of upsetting a bar of iron so as to produce an enlargement at any point between the two ends thereof, and, finally, in Fig. 13 we have illus trated a few of the various forms that may be imparted to metal bars or beams by means of the improved machine.

If desired, shaping-blocks A B of-different thickness may be employed, according to the thickness of the material opera-ted upon, instead of employing filling-out pieces. The various blocking-bars and blocks a a, &c., are detachable from the heads of carriers A B, each having one or more pins or lugs adapted to fit into the holes a and 1), formed in said sections.

In bending angle-iron this is efiectedby applying the power either upon the web or the wing thereof, the same being done when bending T, U, or double-T iron, and suitable filling-out pieces may be employed to preventwrinkling in the web or wings.

Having thus described our said invention and how the same is to be performed, we claim as our invention and desire to secure by Let.- ters Patent- 1.
