Application filed May 25, 1911.

` To all whom it may concern."

Be it known that I, JOHN K. HAUBERG, a citizen of' the United States, and a resident of Cando, in the county of Towner and State of North Dakota, have invented an Improvement in Metal-Rolling Machines, of which the following "is a specification.

My inventfon is a' machine by which iron vor other metal plates are rolled under pres sure and thus drawn out, tapered, or beveled to any required degree.

A distinguishing feature is a roller carried by a. reciprocating frame and adapted to act on a heated metal plate while held on an anvil block, and mechanism for adjusting such block higher or lower, or at dilerent angles, according to the bevel it is esired to impart to the plate.4 The machine enables this resultto be attained quicker than it can bedone by hand, thus saving time and labor, besides doingv the work better. 4

The details of construction, arrangement, and operation ofthe machine are hereinafter described, and illustrated in the accompanying drawings, in which* Figure 1 is a longitudinal-section of the workingJ parts. Fig. 2 is a side View.` Fig. 8 is an end view. Figs. 4 and 5 are cross sections 'on lines 4-4 and 5 5, respectively, of Fig. 1. Figs. 6. and 7 are longitudinal sections on lines 6 6 and 7-7, respectively, of Fig. 1. v

As shown in Figs. 1 and 2, the Y-shaped slotted frame 1 to which the operative parts are applied is mounted and secured upon a base frame 2 having an inclination of about 30 to the horizontal. The upper and lower portions or jaws la and .1b of the frame are parallel and `separated by a considerable space between which the rolling mechanism proper is arranged. A crank shaft 3, provided with a balance Wheel 4, is j ournaled inl the small end of the Y-frame, and a pitman 5 connects it with a bar or thick plate 6 which'is supported Vby suitable means from the upper jaw la, and between' it and said jaw is arranged al series of steel antifrict-ion rollers 7 which are journaled in a frame 8 and adapted to work in contactwith a steel wearlvplate 9 that forms the under face of the upper jaw 1a. The frame 8 .is extended toward the crank shaft and is .operativelyconnected with the pitman 5 by means of a lever 10`f'whose fupper end is connected #A i "r i with the jaw 12l by means of a link 11. The extended portion or shank of'the frame 8 slides through a keeper or block pivoted to the central portion of the lever 10, and spiral springs 12 are arranged on opposite sides of ,this block. It will now be apparent that, b v' the rotation of the crank 3, the bar or plate 6 is reciprocated and that the rollers 7 are also caused to travel back and forth in the space between said, plate and the facing block 9 of the jaw..

A roller 13 having a central circumferential rib is journaled in a short carriage 14 which is provided with` inwardly projecting flanges at 15 that slide in grooves 16 formed in the sides of the bar or plate, 6, before described. This roller works in contact with the under side of said bar or plate 6 and is thus rotated by friction therewith; but it also has an independent movement due to its connection'with the pitman 5 through the medium of the following mechanism. A lever` 17 is pivoted to the pitman and its lower end is connected with the trame by a link 18. A rod or bar 19 is pivoted to the carriage 14 ofthe roller 13 and its extended portion 0r shank slides through a block that is pivoted at the center 20 of the aforesaid lever 17; and spiral springs 21 are arranged on opposite sides of said block. so that the action of the .lever on the roller is, so to speak, cushioned.

On the lower jaw 1b of lthe if-trame is arranged a wedge 22, and a smaller wedge Q3 lies thereon, both wedges being adapted to reciprocate toward or from each other. For adjusting or sliding the larger wedge Q2, it is connected by links 24 with an elbow lever Q5 which is, in turn, connected by a link 26 with a foot-lever 27, which is adaptedvto engage a ratchet bar 28 by which it may be held down in any position to which it` may be adjusted by pressure applied by means of the `foot. When the lever 27 is released. a spring 29, encircling a rod 29a, which slides through a keeper, Will restore or slide the wedge 92 back to its former or normal position. The smaller wedge is connected by links 30 with an elbow lever 31- which is, in turn, connected by a forked link 32-with a foot-lever '33, which is pivoted yto a leg of the base 4trame 2.- A spiral spring that the spring'encircles. It is obviousthat 110 and hold it in, normal position aftervthe-` this spring serves to restore the block to,l

operation of the foot-lever 33.

An anvil block 34 is supported upon the wedges 22 and Q3- and adapted to bead-- jnsted higher or lower or with its face at i different angles, by adjustment 'of thewedges. The block is held in place by'a pin runningthrough it and projecting on the sides, as indicated at 35,' the pin working in slots or grooves in the frame, so that it has a vertical play and also ,allowsthe block to swing in a vertical plane .or adjust itself with the. tace at 'different angles. In other lwords,'the block may be adjusted to any vertical or angular position desired through the medium 'of the wedges 22 and 23, so

l that a metal plate may be drawn out or tapered to any thickness or bevel desired. It will be understood that the roller 13l is made of tempered steel and that the central.

times imposed.

rib is the portion which works in direct contact with the plate held on the anvil 34.

It. will be apparent that. when the plate or bar to be rolled is placed under the roller y13,' the. latter is forced up against the bearing plate or bar 6, which is moved forward and back 'by rotation ot the crank-shaft 3, which, in turn, reciprocates the roller over vthe surface of the material, and it is at the saine time revolved, which has the eiiect of drawing out, tapering, or beveling thevmetal plate. The roller 13 travels one-half the distance that the bearing plate 6 travels, and the steel rollers 7 travel 'one-half the .distance of the said plate. 'In other words,

toward or from each' other according as itA is desired to raise or lower the anvil block 34 or adjust its upper surface at different angles, according to the thickness of the plate to be rolled or the bevel to be imparted to it.

,What-I claim isz- 1. In a metal rolling machine, the corn-l -bination with a supporting frame, of a roller and means for reciprocating it, a fixed guide on which the roller is adapted to travel, an anvil block arranged below the roller and over which the latter'is adapted to reciprocate, and means foradjusting the said block b higher or lower or at' ditferent horizontal planes relative t-o the roller, the same consisting of wedges arranged beneath the block and one -upon the other, and devices connected with the wedges by which either may 'be adjusted for raising-or canting the block,
