UNITED STATES PATENT OFFICE.
EMERSON C. STRANGE, OF TAUNTON, MASSACHUSETTS.
MACHINE FOR SAWING HOOPS.
Specification of Letters Patent No.
To all whom it may concern:
Be it known that I, EMERSON C. STRANGE, of Taunton, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Machines for Sawing Coopers Hoops; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure l is an end view of the machine; Fig. 2, a side view; Fig. 3, a top or birdseye view; Fig. 4, a sectional view of the saw, (the cut being made through the center,) and Fig. 5, a perspective view of the box or bearing for the journal of the sawshaft, next to the saw, showing its connec tion with the lever F and its operation by it.
In the construction of this machine, I make the frame either of metal or wood and of any desirable pattern, being careful to have it of sufficient length to give steadiness to the saw-shaft A. The saw B, which is of the peculiar form shown in Fig. 4, (a circular saw with a beveled edge or flange,) is made fast in the usual manner at one end of the shaft, and the pulley C by which the shaft is driven at the other end of it. The journal box D is firmly affixed to the frame, allowing the saw shaft to slide in it; but the box E is movable, sliding in a dove-tail, as shown in Fig. 5, carrying with it the shield S, the sawB, the shaft A and the pulley C. The motions of this box are governed by the lever F.
Gr is a spring which holds the lever against the cam H.
Upon each side of the saw, at the front edge, is a roll I and J. The axis of these rolls are, as near as may be, in a line with the edge of the saw, or rather that part of the circumference of the saw which is to do the cutting. Directly in front of these rolls and at right angles to them is another roll K. This roll K, together with the roll J (which revolves on a stud permanently affixed to the same piece that holds the roll K,) can be moved to or from the saw and when properly arranged are held firmly in their places by means of the bolt L. The pressure roll I revolves upon the end of the lever M. This lever M has attached to it at 16,407, dated January 13, 1857.
its upper end, beside the roll I, the handle N and the bar or side lever O, the outer end of which rests against the end of the sawshaft that projects beyond the saw. The lever M turns upon a pin P at its lower end, and with the side lever O, the handle N and the roll I are kept in their proper places by the cord and weight R. The distance between the edge of the saw and the pressure roll J shows the thickness of the hoop, which thickness is regulated by the lever F and cam H. Thus by pressure upon the end of the lever F, the ournal box E is moved outward, carrying with it the shaft A, the saw B, the pulley C and the lever M with its attachments, and when at such a distance as to give the desired thickness to the hoop the lever F is kept from returning to its original position by turning the cam H until it presses against it.
Attached to the box E, and moving with it, is a shield or safety iron S, to protect the hoop, while in the process of being sawed, from striking against the teeth of the saw at the farther side.
The advantages I claim and the improvement which I have made (as shown in the machine above described) over all others for the same purpose are the better adaptation of all the various parts to the work to be done. Thus, owing to its peculiar form, the saw will cut around a crook or turn in the hoop-pole, leaving the hoop of the same thickness there as elsewhere, much better than though the saw was either straight or of the concavo-convex form. By having the pressure rolls I and J placed as nearly as possible in a line with the teeth of the saw the support which is obtained by the use of them'v is more effective than though they stood perpendicularly with the frame. By the movable arrangement of the journal box E in connection with the saw, shaft, &c., I can have the roll J firmly fixed, thus giving me an unyielding fulcrum against which to press the hoop while being sawed, much better than though the roll was held in its place by any yielding pressure, 'as a weight or spring. Although the same result may be obtained by the use of a thumb-screw as is eected by the cam H, yet the cam may be used much more readily. These are a few of the advantages resulting from a combination of the various parts as found in this machine and specied above.
I do not claim as my invention the use of pressure rolls upon hoop sawing machines, for these have been used before; neither do I claiin the levers F and l\/I, or the side lever O, or the cam H, by themselves alone, but
/Vhat I do claim as my invention and Wish to secure by Letters Patent, is
l. Making the saw B of the peculiar form as shown in Fig. r-being a plain circular saw with a beveling or angular edge or rim, not confining myself to any particular angle
