SPECIFICATION forming part of Letters Patent No. 293,186, dated February 5, 1884.
i Application filed October 21, 188:2. (No model.)
To .all whom, it may concern:
Be it known that I, JOHN J. MeGrLLIs, a citizen ofthe United States, residing at Marinette, county of Marinette, and State` of `Wlisconsin7 have invented certain new and useful Improvements in Saw-Mill Dogs, which are fully described in the following specification,- reference being had to the accompanying drawings, in which- Figure l represents a side elevat-ion of one of the side pieces ofthe carriage, vshowing the dogs at either end. Fig. 2 is a view of the other side of the same side piece, with a portion of the casing of said side piece removed dogs. Fig. 3 is a plan view, showing the way in whichthe dogs are applied to the side piece ofthe saw-mill carriage. Fig. 4L is a side ele vation of the dogs, connecting-rods, and lever by which the dogs are operated. Fig..5 is an enlarged sectionalview taken on the `line xm,
Fig. 2. Fig. 6 is a transverse sectional view taken on the line y y, Fig. 2. Fig. 7 is an end elevation of a part of the carriage, showing one set of dogs. Fig. 8 is a detached view of one of the link-bars B. Fig. 9 is a detached view of the link which connects the dogs to the link-bar B, and Fig. 10 is a side elevation of one ofthe dogs. l
The `object of my invention is to enable an operator to dog a log to be sawed by a single lever, which is arranged on the carriagethat carries the log in such a manner that the operator by vibrating the lever can apply the dogs to the log for removal, the .lever being' connected by means of connecting -rods to the dogs at each end of the log in such a manner as to enable their application bya single stroke of the lever. In this manner the log is dogged and undogged readily and without delay, so that no time is lostinperforming that work.
My invention consists in the combination of thedgs, connecting-rods, and lever ina sawmill carriage, as hereinafter fully specied and described.
The carriage-frame on which the log to be sawed rests may be constructed in any wellknown way adapted to receive the dogs, as hereinafter fully described. l
l The dogs A are made substantially in the form shown in Fig.- 10, and they are arranged y at each end of the carriage side by side, each dog lying in a recess or groove, G. Ipreferably arrange several of these dogs side by side, and connect them with bolts D, whichpass through them, so that the dogs are all operated together by means of the connecting-link L, which is attached to the dogs, as shown.
B is a link-bar placed in a recess or groove between guides E.
F is a connecting-rod that connects the linkbar B to the lever G. rIhis connecting-rod F isattached to the link-bar B by hooking it through one of the holes in the link-bar, and by changing it from one holle to another the dogs are adjusted to logs of different lengths.
G is a lever having fnlcrnm at H, and I is a notched segment adapted to hold the lever at `any desired position.
It will be observed that the same system of dogs and connecting rods is operated at each end of the log from the lever G, andthe dogs A are all moved back and forth 4in their groove C simultaneously, but the connectinglink is so attached to them that the dogs, in entering the ends of the logs, will conform somewhat to the irregular shape oi' the ends. The dogs in the upper grooves will enter the end of the log, and the dog in the lower groove can stilladvance sntliciently far to enter the end of the log,'if it is not cut evenly, and vice' versa. It will be observed that the long grooves in which the dogs are placed allow a long stroke of the lever, so as to adapt 'the application of the dogs to logs of different lengths, and, as before stated, the connecting-rods ca-n be adjusted to different holes in the link-bar I3, so as to allow the application of the dogs to longer or shorter logs when thereis a very great variation in their lengths. These hooked dogs A project their sharp 'ends sufficiently far to enter the log in a manner to hold it firmly in place, and the operator by asingle stroke of the lever G can immediately remove and apply the dogs to alog, and the toothed segment I holds the dogs firmly clasped in the end of the log by the means clearly shown in the drawings.
I nd by the practical application and use of my saw-milL dogs that I am enabled to fayand save a good deal of time and expense.
The size of the dogs and their forms and shapes may be varied, and the dimensions of the different parts may be changed to adapt them to carriages of different sizes; and it will be,
readily seen that the dogs may be applied to the 'side of the log as it is rolled upon the carriage, or to the bottom of the log,as may be preferred. In my application, however, I have applied them to the side of the log, and lind that my system of dogs Works very efficiently and readily.
Having thus described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent, 1s-
l. In a saw-mill, an ordinary reciprocating carriage on Which the log rests, in combination with one orl more dogs arranged at each cnd of the carriage, and mounted thereon'in a Way t0 permit a reciprocating movement of said dogs on the carriage, a lever on the Carriage, and devices for connecting the respective dogs to said lever, whereby the dogs may be operated simultaneously and from one position to dog and undog the logs upon the carriage, substantially as described.
2. In a saW-mill, the log-carriage provided with grooves G at each end, in combination with dogs A, arranged to slide in said grooves at each end of the carriage, the links L, the link-bars B, the connecting rods F, and the lever G, substantially as and for 'the purposes set forth. K A
3. The reciprocating logcarriage, in coinbination With the sliding dogs A at each end thereof, the lever G on the carriage, the rods F, connecting the dogs at the respective ends of the carriage to the lever on opposite sides of its pivot, the notched segment I, and a pawl on the lever arranged to engage with said segment, substantially as and for the purposes set forth.
