UNITE i GEO. H. CORLISS AND ELISHA HARRIS, OF PROVIDENCE, RHODE ISLAND.
ROLLING METAL.
Specification of Letters Patent No. 14,279, dated February 19, 1856.
To all whom t may concern Be it known that we, Gr. H. CoRLIss and ELISHA HARRIS, of the city and county of Providence and State of Rhode Island, have invented certain new and useful Improvei ments in Machinery for Rolling Metal; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specication, in which- Figure l, is a vertical longitudinal sect-i011 of a rolling machine constructed according to'our invention. Fig. 2, is a plan of t-he same. Fig. 3, is a transverse section of the machine in the p-lane indicated by the line m, 1, in Fig. 1. Fig. 4L, is an end view of the roller carriage and one of the sliding boxes in which it is fitted.
Similar letters of reference indicate corresponding parts in the several figures.
This invention consists in a certain arrangement of and method of operating a roller -to roll over a stationary table for the purpose of producing articles of taper or other form.
To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.
The machine represented in the drawing is particularly intended for the rolling of strap hinges, but is also applicable to the rolling of other articles either of taper or parallel form, and by a mere change in the form of the bed is capable of producing other forms. It therefore serves with the aid of proper explanation herein given to illustrate our invention fully.
A, A, is a strong frame work of cast iron 40 supporting a stationary horizontal bed B, of the same material upon which is placed and secured the stationary rolling table C.
In the two sides of the framing there are two straight and parallel openings D, D, to
` receiveand form O'uides for the two sliding 4 boxes E, E, to which is fitted the roller carriage F, which contains suitable bearings for the Journals a, a, of the roller G. The ends l.of the roller carriage are furnished with ',udgeons Z, b, which project outside the amlng, and are connected by two connectngrods H, H, with two cranks I, I, on the driving shaft J, of the machine. By the revolution of the cranks a reciprocating motion 1S, given to the roller carriage over the face ofthe rolling table, and a piece of properly heated metal placed upon the t-able is reduced to a form and thickness depending upon the position of the upper surface of the table relatively to the guides D, D. This position is variable by means of .wedges c, c, placed between the table and the bed B, and made adjustable by screws d, el, so as to produce different degrees of Obliquity between the said surface and the guides, and thereby to produce different degrees of taper on the work as may be desired. The table may however be set parallel with the guides for parallel rolling if desired.
Two important. features. of the machine are the position of the crank shaft J, relatively to the rolling table, and the upward movement given to the roller carriage as it completes its movement toward that end of the machine where the rolling operation commences, which is at the left hand end of Figs. l, and 2.
The first of the above named features, viz, the position of Jthe crank shaft is illustrated in Fig. 1, where it will be seen that the said shaft is placed some distance below the rolling table, the effect of which is that the cranks revolving in the direction of the arrow shown near it (in which direction they always revolve) in descending from the position shown in black outline and drawing the roller carriage in the direction of the arrow near it which is the direction in which the rolling is performed exert a strong tendency to draw down the roller upon its bed. By that means thepart of the framing above the guides D, D, is relieved of much strain and friction which would otherwise be produced against the upper sides of those guides.
The other important feature which has been mentioned, viz., the upward movement of the roller carriage as its return movement after a rolling operation has been performed, is for the purposev of enabling the piece of finished work to be easily taken from the machine, and a new piece to be placed under the roller and upon the bed ready to be submitted to the action of the next movement of the roller on the bed. The raising of t-he carriage is eected by the peculiar manner of fitting and applying the sliding boxes to it. Each box is made with a slot e, e, whose upper and lower sides are parallel but oblique to the guides D, D, as shown in Figs. l and 4. Those parts of the gudgeons of the carriage which fit to the said boxes are made of a form to correspond lot with and be received in the said slots e, e, fitting snugly to the upper and lower sides thereof, but not filling the said slots from end to end. When the carriage moves in the direction of the arrow shown near it in Fig. l, the gudgeons are at those ends of the slots where they are shown in Fig. 4, and in red outline in Figs. l and 2; and during the return movement in the opposite direction they are kept at the same ends of the slots by the tongues of two latches L, L, which are pivoted to the gudgeons outside of the boxes,v and have springs 7", f, applied to them to throw them inward, as shown in red outline in Fig. 2, where one of the boxes is shown in section. But a little time before the return movement of the carriage is completed the ends of the latches come in contact with two fixed studs g, g, shown in Fig. 2, and are thereby forced outward far enough to draw the tongues of the latches from between the gudgeons and the ends of the slots and by the time this has been accomplished the boxes arrive at the ends of the guides l), D, where they are arrested, after which the remainder of the movement of the carriage causes the gudgeons to travel up the slots in the boxes, whereby the roller carriage is raised up. During the first part of the succeeding movement of the carriage it descends by reason of the gudgeons moving down the slots, and after the gudgeons have reached the lower ends of the slot-s the latches fall into the slots again. It may be well here to observe that the position of the crank shaft. as before described and consequent downward pull which is given to the carriage is almost absolutely necessary were it for no other reason than to insure the above downward movement of the carriage at the very. commencement of its movement in the direction of the arrow.
In rolling hinges or other articles from a parallel to a taper form the reducing act-ion of the rollers may be made to commence as soon as the carriage reaches the bottom of the slots in the boxes, or not until it has passed some distance over the table. This is governed by raising the table higher or lower.
By giving the rolling table a curved surface articles of curved form on one side and straight on the other side may be produced.
One great advantage resulting from the use of the roller and table over using a pair of rollers is that by the former no straight ening is required after rolling. When two rollers are used the cost of straightening is sometimes greater than that of reducing. Another advantage is that it is more convenient for rolling articles which cannot be passed entirely through the rollers as in rolling strap hinges after their eyes or loops have been formed. A strap hinge is shown in the machine in Fig. l in blue color.
Having thus fully described our invention, we will now state what we claim and desire to secure by Letters Patent,
1. We claim the combination of the reciprocating roller carriage, F, with the guides, D, D, and a table, E, substantially as herein described.
2. lVe claim raising the roller, Gr, for the purpose of placing the work between it and the table, C, by fitting the roller carriage, F, to oblique slots, (e), (e), in the sliding boxes, E, E, and providing latches, L, L,
' operating as described, to secure the carriage in the sliding boxes during the rolling operation but to loosen them and allow them to run up the slots as herein set forth at the termination of the return movement of the roller.
3. We claim the arrangement of the crank shaft, J, relatively to the rolling table, C, and roller carriage, F, substantially as herein described for the purpose set forth.
