METAL-PLANING MACHINE.
SPECIFICATION forming part of Letters Patent No. 296,951, dated April 15,1884.
Application filed October To all whom it may concern.-
Be it known that I, GEORGE A. GRAY, J r., of Covington, Kenton county, Kentucky, have invented certain new and useful Improvements in Metal-Planing Machines, of which the following is aspecification.
This invention relates to the motion-controlling devices of metal-planing machines.
The object of the invention is to enable the table to run back past the back reversing-dog without endangering the planer by running latch, and Q the stop-dogi the table entirely off its actuating-gear. By means of my invention theplaner may operate as usual, and in case it is desired that the table be run farther backward than the length of cut requires, or than the back dog would naturally permit, the back dog may be manipulated so as to permit the table to have a iur ther back travel, limited only by a third dog, which prevents the table leaving its gear.
1n the accompanying drawings, Figure l is a plan of one edge of the planer-table with dogs and tumbler in posit-ion. Fig. 2 is aside view of the same, being shown in section on linea a. Fig. 3 is a side view modified to suit a planer having a vertical tumbler.
In thedrawings, A represents the table of the planer; B,the tumbler; G,thetumbler-support; D, the rod connecting the tumbler with the belt-shifting apparatus, whatever it may be,- E, the tumbler-handle, by means of which the tumbler is operated by hand; F, a dotted line indicating the position of the tumbler when the table is on its forward or cutting motion; G, a dotted line indicating the position of the tumbler when the table is on its backward or non-cutting motion; I, the tumblertoe, to be struck by the back dog; J, alug on the tumbler, to be struck by the stop-dog; K, a lug on the tumbler, to be struck by the front dog; L, the front dog; M, the back dog; N, a striking-latch pivoted in the back dog; 0, the pivot of the latch; P, aknob attached to the The dogs adjust, as usual, along the edge of the planer-table, and the dogs L and M effect the shifting of the belt, and the consequent reversal of the table motion, as usual. The latchNformsthestriking part of the back dog, M.

lug-K, throws tumbler to the position indicated by line G, and causes the table to reverse its direction of motion. stroke the dog M, by its latch N, strikes toe I, throws tumbler to position indicated by dotted line F, and causes the tableto makeanew cutting stroke, and so on as long as desired. If it be desired to run the table out from under the rail further without disturbing the back dog, M, the latchN is lifted up by the knob P. This practically suppresses the dog M, and the table continues its backward motion until the stop-dog Q strikes the lug J and throws the tumbler into the neutral position, thus stopping the table. WVhen it is desired to restart the planer, the tumbler is thrown by hand to the position indicated by the line F. The table thenstarts forward, the latch N automatically giving way in passing the tumbler, and the motion proceeds as before, being governed by the dogs L and M. For short planers the stop-dog Q may be rigidly fixed near the back end of the table, so that the'liftingof thelatch will simply serve to permit the table to move back its full stroke and then stop; but the arrangementof the stop-dog to be adjusted to any point is preferable.
Metal-planers are ordinarily arranged to have their tables travel backward about twice as fast as'they travel forward. Under such circumstances the construction specified will probably prove all'that is desired. There has, however, lately been a tendency toward greatly increasing the backing speed of planer-tables, such backing speed in some cases being as much as five times the cutting speed. Under such circumstances it will readily be understood that while the table is moving back at this extraordinary speed it will not come to rest immediately when the stop-dog Q throws the tumbler to the neutral point, as previously specified. Momentum at these high backing speeds may carry. the table far beyond the proper point, and this force is so liable to vary that its action cannot be properly compensated for by any skillful setting of the stop-dog Q. For this reason I so construct the partsin connection with planers to run back at extraordinary speeds that the stop-dog Q will not only throw the tumbler to the neutral point, but will throw the forward belt into action. This At end of backing causes the planer-table to commence its slow forward motion, causing the stop-dog to immediately strike the'lug K and throw the turnbler to theneutral position. It will be readily understood that the only change thus effected in the operation of the device is that the stopdog is caused to perform'its function while the planer is on a slow forward motion, instead of vupon the rapid backing motion. The change is effected by extending the lug J, as indicated by the dotted lines It.
In the drawings I show in Figs. 1 and 2 the tumbler arranged horizontally, and in Fig. 3 the tumbler arranged vertically. I cont-emplate such modifications in the forms of the dogs as will adapt the invention for use with any of the well-known forms of reversing-tumblers.
In the drawings I simply illustrate the principle of my invention and the best mode in which I contemplate applying that principle.
I claim as my invention 1. In a metalplaning machine, the combination, substantially as set forth, of a revers- 3. In a metal-planing machine, the combi nation, substantially as set forth, of a reversing-tumbler, a front dog, a suppressible back dog, and a stop-dog fitted to throw the tumbler and start the forward table motion, and upon its retreat to throw the tumbler to a neutral point.
