UNITE STATES PATENT FFICEQ ALPHEUS E. ROE, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR TO TATUM & BOWEN, OF SAME PLACE.
'sAw- MILL SET-W R KS.
SPECIFICATION forming part of Letters Patent No. 353,886, dated December 7, 1886.
(No model.)
To all whom it may concern.-
Be it known that l, ALPHEUS E. Ron, of the city and county of San Francisco, State of California, have invented an Improvement in Saw- Mill-Set-Works; and I hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to certain improvements in saw-mill set-works.
It consists of a mechanism by which the ratchet-wheels attached to the screws of the head-blocks may be rotated an equal amount by the upward and downward movement of the operating-lever, and in a means for regulating the amount of cut in inches and fractional parts, together with certain details of construction, all of which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a side elevation of my apparatus. Fig. 2 shows the device for limiting the movement of the operating arms and lever and determining the amount of cut to be made.
In the mechanism for operating the feedscrews of the head-blocks in saw-mills considerable difficulty has been experienced in making the movements exactly the samewhen the lever is moved upward and downward, so that a certain number of movements of the lever will produce a corresponding movement of the screw, whether the movement be upward or downward.
In my invention, A is a ratchet-wheel keyed to the end of the head-block screw, and B B are pawl-cases fulcrumed about the center of the ratchet-wheel, and having the pawls C C pivoted to them, so as to engage the teeth of the ratchet-wheel upon opposite sides. The pawl cases or arms B B, upon which the pawls are fulcrumed, have their bearings upon the screw-shank, or so as to turn about the same center, so that when they are moved up and down by means of the lever-arm X it will be seen that a certain movement in either direction will produce a corresponding movement of the pawls.
The pawl C upon one side of the ratchet has its points or ends so constructed that when the 50 lever is raised it will move the ratchet-wheel forward, and the pawl 0 upon the opposite side of the ratchet-wheel A is reversed, or has its ends so formed that they will engage the teeth of the ratchet when the arm B is moved downward.
In order to move the arms B B up and down simultaneously upon opposite sides of the ratchet-wheel A, links or arms D D are connected with them, extending upward and uniting with a yoke, E, which travels between vertical'guides G. The yoke E is provided with anti-friction rollers F, which prevent its binding and cause it to move more easily. It will be seen by this construction that when the lever X is moved upward it carries with it the arm B, and by means of the link D, the yoke E, and the link D the arm B is moved upward simultaneously.
The pawl G will engage the teeth of the ratchet-wheel upon one side when the lever is moved upward, the pawl C slipping over the teeth upon the opposite side, and when the lever is moved downward the pawl C will engage the ratchet teeth, so as to continue the rotation of the wheel, the pawl C slipping over the teeth without action. By this means the upward movement of the lever over a certain space will rotate the ratchet-wheel A a certain distance, and the downward movement of the lever over the same space will cause it to ro- 8o tate exactly the same distance.
In order to limit the upward movement of the lever, and consequently the number ofteeth which the wheel will be rotated by each movement, I have fixed a stop in the upper part of the guide G, having five arms of unequal length, as shown at P. This may be turned so that either of the arms is presented in line with the guides so as to act as a stop for the upward movement of the yoke E, and the movement will thus depend upon the arm which is presented as a stop, and by this the thickness of the lumber to be cut will be easily determined, a certain number of upward and downward movements of the lever rotating the feed-screw so as to advance the headblock the desired distance. i
In some cases it may be desired to increase the movement slightly say one or two teeth of the ratchet-wheel--and this may be done by means of an adjustable block, 0, fitted between the guides G at the lower end, and connected I with a cam or eccentric, L, the rotation of which would raise and lower the block 0 the distance corresponding with its own movement. This movement is effected by means of a lever, M, fulcrumed at one side, and connected with the eccentric or cam so as to turn it and thus raise or lower the block 0. The lever-arm M is held at any desired point by means of a segmental rack, N.
H H are curved arms, the peripheries of which correspond nearly with that of the ratchet-wheel A, these arms lying justinside of the teeth of the wheel, as shown, when the device is being operated. The arms are fulcrumed upon a pin at I, and have short arms extending upwardly, diverging from that point. J is a lever, slotted so that these upwardly-extending arms H pass through the slot in the lever. When the lever is down, or in its normal position, the sides of the slot do not touch the lever-arms, and they remain as shown in the drawings. When the lever-arm J is raised, the sides of the slot press upon the diverging arms H, and this causes the curved arms H to be separated so as to touch the points of the pawls O and O and raise them clear of the teeth of the ratchet-wheel A. This allows the head-block to be turned back by hand.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- .7
1. Ina saw-mill set-works, the ratchet-wheel secured to the head-block screw, the arms B B, mounted on said screw and extending in opposite directions, the pawls O O, journaled in said arms upon opposite sides of the ratchetwheel and alternately operating said wheel, in combination with the vertical guide-rods, the yoke E, moving in said guide-rods, the links D D, connecting the yoke with the arms B B, a stop at the upper end of the guiderods, having arms of unequal length, as described, and the adjustable block 0 at the lower end of the guide, substantially as herein described.
2. The ratchet-wheel on the head-block screw, the arms B on said screw, having the alternately-operating pawls O G, and a yoke connected with said arms, in combination with an adjustable stop composed of the arms projecting radially unequal distances from a central shaft, about which they may be turned so as to act as a stop for the upward movement of the yoke E, substantially as herein described.
3. In combination with the pawls fnlcrumed to the lever-arms moving about a common center with the ratchet-wheel, links connecting the arms with a yoke which moves in a vertical guide, as shown, the movable block or stop at'the lower end of the guide, the cam or eccentric connected with said stop, by which from the teeth of the ratchet-wheel, substantially as herein described,
In witness whereof I have hereunto set my hand.
