IMPROVEMENT IN MACHINES FOR SLITTING, BEVELING, AND BENDING METALTUBE SKELPS.`
Specification forming part of Letters Patent No. 111,015, dated January 17, 1871.
To all whom 'it may concern:
Be it known that I, STEPHEN P. M. TASKER, ot the city of Philadelphia, and State of Pennsylvania, have invented certain Improvements in Machines for Slitting, Beveling, and Bending Metal-Tube Skelps, of which the following is a specification.
The nature of my invention consists in the combination ot' stationary cutters ot' suitable form to slit the sheets and bevel the edges of the skelps at one operation with the feed-rolls and-the first pair of bending-rolls. By this means the operation of making the tubes is greatly simplified and expedited.
To enable others skilled in the art to which my improvement appertains to'make and use my invention, I Will now give a detailed descriptionthereof. y
In the accompanying drawings, which make a part of this specification, Figure l is a plan view of theimproved machine. Fig.2is a ver- 1ical section at the line a: x of Fig. 1. Fig. 3
. is a side view ofthe cutter-bar H and cutters J J J' detached from the machine. Fig. 4 is a back view of the middle cutter, J, detached from the cutter-bar H. Fig. 5 is a like View ot'one ofthe outside cutters, J'. Fig. 6 is an end view ot' a jiat s-kelp for forming a lap-joint tube. Fig. 7 is a like view ot' a butt-joint skelp. Fig. 8 represents an end view Vof a skel p when passed through the rolls K K'.
Like letters in all the igures indicate the saine parts.
A is the bed-plate ofthe machine, and B B the housings connected therewith. To the latter the several parts of the machine are coni nrcted. l conne by means ot' bolts a on the horizontal plate C, connected at each end of the housings B B, a mouth, D, which is provided with grooved carrying-wheels E E E E, that convey the sheets to the feed-rolls F F. These rolls are geared together by means of wheels G G, and pass the sheet to the bending-rolls. As the sheet passes the feed-rollsit comes in contact with the vertical cutters JJ' J' in the cross-bar H. The said cutters slit the sheets intothe right widths for the skelps, and bevel the edges ot' the latter at the same time. The cutters are situated in slots-of the bar H, and are confined in their adjusted position by means ot' set-screws 7c. The middle cutter, J, has a double angle, b b, as seen in Figs. 3 and 4, so as to bevel the contiguous edges of both skelps; but the outer cutters, J' J',have each a single angular cutting-edge, as shown in Figs. 3 and 5.
To prevent the buckling of the sheets of metal as they pass from the feed-rolls to the bending-rolls, 1 confine between the housings B B guide-plates D' D', the upper plate heilig slotted for the passage of the cutters. After the skelps pass the cutters they are caught by the double bending roll K K', situated on the shafts 1 l', which bend them into theform represented iu Fig. S.
The feed-rolls F Fand shafts 1 l',` on which the bendingsrolls K K' are situated, are geared together by means ot' the wheels L L on the said shafts 1 l' and wheel L' on the short shaft 2, the latter gearing into the wheel Got' the lower roll, F, as seen in Fig. 2. Power being applied to either shaft of the series, the feed and bending rolls are caused to revolve in the direction of the arrows,whereby the sheets are slit into skelps, and the latter beveled on their edges and bent into the forln represented in Fig. 8 as they pass through the machine.
Other rolls may be added as may be desired to give the finishing bend to the skelps.
What I claim as my invention, and desire to secure by Letters Patent, is
1. The adjustable beveled cutters J J' J',in
4combination with the guide-plates D' D' and feed-rolls F F or their equivalent, substantially as described.
2. The combination and arrangement of the feed-rolls F F, guides D' D', beveled cutters J J' J', and bending-rolls K K', for slitting, I
beveling, and bending the skelps at oneopera tion, substantially as described.
In testimony that the above is my invention I have hereunto set my hand and affixed my seal this 30th day of August, 1870.
