FRANK W. CAMERON, OF FRANKFORT, NEW YORK.
HOE-ROLLlNG MACHINE.
Application filed September 23,1906.
T0 at whmn it puny (to/warn.-
Be it known that I, FRANK W. CAMERON, a citizen of the United States, residing at Frankfort, in the county of I-Ierkimer and State of New York, have invented certain new and useful Improvements in Hoe-Rolling Machines, of which the following is a specification, reference being had therein to the accompanying drawings.
My invention relates to an improved hoerolling machine; and I declare that the following is a full, clear, concise, and exact de scription thereof, sufficient to enable one skilled in the art to make and use the same, reference being had to the accompanying drawings, in which like letters and numerals refer to like parts throughout.
My invention relates particularly to the combination and arrangement of lever connections to take the place of pinion-gears, and is particularly applicable to such machines, though it may be also used in other connections or circumstances where like results are sought. I therefore do not limit myself to this particular showing of my device.
The purpose of my invention is to render the operation of the machine more certain, efficient, easy, and prompt, whereby I am able to avoid certain defects in the machines now being usedfor instance, in the manufacture of hoes-and to manufacture the product with exactness and uniformity.
The invention will be fully disclosed in the following description, which is to be read in connection with the drawings, in which like letters and numbers refer to like parts throughout. I
Figure 1 is a perspective view of a familiar machine having my improved device mounted thereon. Figs. 2 and 3 are side views showing the devices in extreme operative positions, the medium position being shown in Fig. 1. v Fig. 4 is a side view in section on the line as a; of Fig. 5, which latter figure is a front View of the device in the position shown in Fig. 3.
Referring to the figures more in detail, A A represent the housings of the machine, which are provided with integral or attached bases A. These housings are of the proper form and size and arrangement to support transversely the two rollers B and B, the latter of which is mounted in suitable journals (not indicated, but readily understood) and the upper of which is mounted in boxes which are adjustable vertically in the hous- Specification of Letters Patent.

which are so fashioned that as the rollers turn the dies open and shut in their swing with the roll, so that metal passed between the dies is rolled to the proper thickness and size. The rollers extend beyond the housings, as seenin Fig. 5, and are provided with dies, as indicated, but not particularly described. These particulars are common in machines of this character.
C is a leverarm operatively connected with one of the gears C, by which the train is operated to raise or lower the upper roller to regulate the thickness to be given to the metal between the dies.
E represents the shaft, which has a flywheel (not shown) and a gear E, from which the shaft receives its power and which shaft carries crank-arm E, which has the pitman F, which extends to and is connected with one or more arms F, connected to the lower roller, so that the reciprocating movement imparted to the shaft rocks the lower roller to and fro. Of course any suitable mechanism is appropriate to accomplish this result, it being suitably formed and arranged for the purpose.
I-Ieretofore the outer ends of the rollers have carried pinion-gears which intermeshed and the lower of which, turning with the lower shaft, imparted motion to the upper roller or shaft. The difficulty has been that there was loss of motion in this form of device and an unnecessary use of power and that the dies in their turning to and fro would not be accurate in their interplay and that the gears especially would become rapidly worn and the operation of the machine be more and more variable and more inaccurate. To obviate this and procure greater leverage, I mount on the lower shaft crank-arm 1 and on the upper shaft crankarm 2. Each housing is provided with an abutment 1, which may be integral or attached and which housings carry a shaft P. On this shaft I mount an elbow or bellcrank obviates any such objection.
A great advantage of the invention lies in the fact that the reciprocation of each roller is synchronous and eXact in extent and that thereby the dies operate with uniformity, and there is no play by which one die can start its movement ahead of the other by rea son of any play between the teeth of the pinions, which have been heretofore used on the rollers or shafts.
A considerable item has been the necessity of replacing worn pinions, as every particle of wear would afiect the operation of the dies, and it will be seen that the device I employ It should be further noted that this device can be readily applied to any of the old styles of machines and answers all of the requirements, while its operation is far more accurate and econom ical in the use of power.
Variations and modifications will be apparent to those skilled in the art, intending to include in this illustration all applications, modifications, and variations which may be used without departing from the spirit and scope of my invention.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a device of the character described, having die-bearing rollers, a crank arm mounted on each roller and a bell-crank with link connections between the same and the said crank-arms to reciprocate the latter to and fro.
'2. In a device of the character described having rollers and means to reciprocate one of the same, a bell-crank lever, and operative connections between the arms of the said lever and the rollers whereby to transmit power from the reciprocated roller to the other roller to reciprocate the latter instantaneously with the action of the former roller.
In testimony whereof I afliX my signature in presence of two witnesses.
FRANK W. CAMERON.
