IMPROVEMENT IN SAW-SWAGING MACHINES.
Specification forming part of Letters Patent No. 149,584, dated April 14, 1874; application filed November 29, 1873.
To all whom it may concern.-
Be it known that I, WILLIAM GLUE, of Muskegon, county of Muskegon and State of Michigan, have invented certain new and useful Improvements' in Machines for Swaging Saw-Teeth; and I do hereby declare the following to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and usek it, reference being had to the accompanying drawings, which form part of this specification, and in which similar letters of reference indicate corresponding parts in the different figures.
Figure l represents the machine in perspective. Fig. 2 is a side view, and Fig. 3 represents the front, of the machine.-
This invention relates to that class oi' machines used for the purpose of spreading the teeth of saws at their points, in order to obviate the necessity of setting the same by bending them alternately to the right and left, so as to make the saw cut a kerf wider than its thickness, thereby avoiding the excessive friction and consequent heat which would result were the kerf cut no wider than the thickness of the saw-plate; and it consists in the`construction of the sWaging-dies, and in the arrangement of the devices used for operating them.
A represents the bed of the machine, made preferably of iron, and formed by casting in a single piece, by which method of construction great strength and rigidity are secured. The legs are provided with feet, which project laterally, and are pierced with holes for the insertion of screws or bolts, by means of which the machine may be securely fastened to a iioor or other suitable bed-timbers. The upper part of the bed A is formed into a way or slide having a dovetail shape, the broadest part being its upper surface. Upon this way slides the block B, provided with a set-screw, b, or other equivalent device, by which it may be secured at any desired point in the length of the bed. Attached to one side of this block B, by a pivot, is a lever, I, one extremity of which is enlarged, .so as to form the segment 0f a circle, and is provided with an eccentrically-placed slot, through which passes a pin secured in a die-block, C. This block is also movable upon the bed in a manner similar to block B. It is not, however, secured to the bed, but is allowed a limited reciprocating movement thereon, controlled by the action of die-block, and has inserted in the end nearest f its fulcrum a steel swaging-die, a,which,when the rear end of the lever is raised, impinges upon the die d, oran interposed saw-tooth. The vertical bar D is secured to the bed A, and is provided with a projecting ledge, against which the back of the saw H rests.y It is also further secured by the clamp F, which holds the saw firmly at any desired height by the action of a clamping-screwpassing through one arm of the clamp, and which is brought to bear again st the saw. A projection, L, from one'side of the bed A, carries upon its outer end one bearing ofY the spindle E, the other being upon the main bed at c. This spindle is provided with a fixed and removable collar similar to those upon the arbors of circular saws, and it is used for holding circular saws in a proper position for the swaging of their teeth, the block B and die-block C being moved toward the rear end of the bed so as to give a distance between the swaging-dies and spindle equal to the radius 0f the saw which is to be operated upon.
The operation of the machine is as follows:
A saw having been secured, (if circular, upon the spindle E 5 but, if a muley or gang saw, to the bar D,) the set-screw b in the block B is loosened and the lever I raised, so as to cause the eccentric slot to draw the die-block back against the block B. Both are then placed in such a position that the saw may be moved without its teeth touching the swaging-dies, but passing very close to them. The block B is then secured in its position upon the bed by the setscrew, when a downward movement of the lever moves the die-block forward, causing the swaging-die d to enter the space between two of the saw-teeth. The tooth above the die is then allowed to rest upon it, and the Alever K being raised, the die a is brought' into forcible Contact with the point of the tooth, drawing out and spreading it at one operation.
Having thus described my invention, I claim as new and desire to secure by Letters Patent the following:
l. The bed A, in combination with the block B, lever I, and dieblock C, as und for the purpose specified.
2. The reciprocating dieblock C, operated by the eccentric lever I, and provided with die with the swinging devices, as and for the purpose herein set forth.
In test-in1on37 that I claim the foregoing, I have hereunto set my hand this 28th day of October, 1873.
