UNITED STATES PATENT OFFICE;
TAPPING REEVES, on ALBION, CALIFORNIA.
IMPROVEMENT IN SA WING-MACHINES.
Specification forming part of Letter'slateht No. 50,627, dated October 24, 1865. I
To all whom it may concern:
Bei't known that I, TAPPING REEVES, of Albion, in the county of Mendocino and State of California, have invented a. new and useful Improvement; in Machines for Edging Boards and other stuff; and I do hereby declare that the following is a full, clear, and exact descripsponding parts.
My invention consists in an improved method of moving the feeding-platform of an edging-table.
Arepresen ts the table supported upon a suitable frame. Y
B is the feeding-platform, upon which the stuff to be edged is carried to the saw S. It is supported upon the usual friction-rolls, a, and is guided in its reciprocating movements by the guide (I, fitting in a groove on its lower side.
A transverse shaft, 0, is secured in proper journals in the frame of the table just in front of the saw. It carries a friction-wheel, (J, loose upon it, upon the inner hub of which is formed two teeth, D, of a clutch,whose other teeth, D, are formed upon the adjacent end of a sliding collar, E, which slides upon the shaft through the operation of a right-angled shipper, 1, which is supported upon a bracket, h,
and which projects through the front of the table, where it has a handle or knob formed The inner end of the shipper F is forked, so as to embrace the sides of a semiring, E, whose ends are bent radially, so as to project into opposite sides of a circular groove out around the sliding collar E. t
The semi-rin g has a spur, j, formed upon it, which projects upward from its periphery, being wedge-shaped in the direction of the plane of the semi-ring. The semi-ring-constitutes the fork by which the sliding collar is moved upon the shalt, and itis supported by an universal joint upon a bracket, I, which is fixed to a cross-piece, A, of the table. That portion of the shaft which carries the sliding collar is square, as is the aperture in the collar which receives the shaft, so that the collar must revolve with the shaft,,while it is free to slide thereon longitudinally.
The friction-wheel G is made with an elastic periphery, which may be of any suitable material. A convenient way of constructing this wheel is to raise a. flange from its hub and bolt wooden blocks thereto on each side, which latterma y then be turned ofl'true, when they will furnish aconvenient foundation for attaching the elastic material which forms the periphery Of the wheel.
Theelev'ation of the friction-wheel may be.
graduated by means of a key or other suitable mechanical device to elevate or depress the journal box or boxes of the shaft which car'- ries it.
A driving-pulley, H, fixed upon the shaft 0, furnishes the means for driving the friction. wheel.
A dog, a, is fastened to the under side of the feeding-platform B, at its outer end, on such a line as to strike against the wedge-shaped spur or projection j of the shipping-fork E when the platform passes thefriction-wheel.
()ne of the advantages of this invention is that it enables the operator to ease up on the saw when itis passing through knots or spongy lumber by holding back on the platform, which could not be done if the platform was moved by a positive movement, such as that of a rack and pinion.
It is evident that the friction-pulley may be arranged to drive both ways by extending the shaftthrough to the back side of the table and running it by a straight and a cross belt, the same as one lathe.
The operation is as follows: The platform B being ready toZfeed its lumber to the saw to be edged,.the operator causes the teeth of the sliding collar to engage the teeth D of the friction-wheel. The platform is now pushed along until it comes in contact with the frictionwheel, which drives it forward, so that the stuff is impelled against the saw S. 'When the platform has passed the pulley the dog 72 disengages the clutch D D, and the operator returns the platform to the other end of the table again.
I claim as new and desire to secure by Letters Patent- 1 The combination of the (log n, on the travelin'g platform, and the shipping arrangement scribed.
and clutch, or their equivalents, with a friction-wheel which drives the said platform, substantially as and for the purpose above de- TAPPING REEVES. t
