WITNTSSES & 452%@ UNITED STATES PATENT OEETCEa THOMAS MANLEY, OF PRINCE ALBERT, NORTH-WEST TERRITORY, CANADA.
SAW-MILL DOG.
sPEcIr'IcA'rIoNferming part of Leiters Patent No. 358,159, dated February 22, 1887.
Application filed April 8, 1886. Serial No. 198,174.
To all whom it may concern:
Be it known that I, THOMAS MARLEY, of Prince Albert, North-vest Territory, Canada, have invented a new and Improved Saw-Mill Dog, of which the following is a full, clear, and exact description.
My invention relates to the construction of a saw-mill dog that is more particularly intended for dogging small tapering logs, but which is equally well adapted to the dogging of large straight logs or to the holding ofthe Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate vcorresponding-parts in all the figures.
-Fig. 3 is a vside view representing thedog in connection with a log. Fig. 4 is a vertical sectional view taken on brokenlinex x of Fig. l,
and Fig. 5 illustrates certain lever attach-y ments whereby the Sawyer may do his own dogging.
In constructing such adog as isillustrated in the drawings above referred to I provide an inclosing-case, A, formed with horizontal ways a a, which serve as guideways forthe sliding rack B, in which the vertically adjustable bars D D, which carry the teeth C C, are mounted. The rack B is formed from two forward vertical strips, b b, and two lower horizontal strips, c c, which ride in the lower grooves or recesses, a, of the case A, the rear ends of the strips being spaced by an interposed block, c. (Shown in Fig. 2,and in dotted lines in Fi g1.) Intermediate horizontal strips,
d d, are arranged to ride in the grooves o ol the case A, the strips d being braced by brace-V bars d', which extend forward to connect with the vertical strips or bars b.
The approaching faces of the strips b are formed with recesses e' e, in which the vertically-adjustable teeth-carrying strips D are arranged. The teeth C are munted between the strips D on pivot-pins e', and are provided with weighted counterbalancing-arms f,which act to hold the teeth against limit-pins f', so that the normal position of the teeth will (No model.)
be that in which they are represented in Fig. 1. In order that the teeth may not be thrown over, and also in order that the bars D D may be securely held together, I provide other limit pins or bolts, g, as shown best in Fig. l. The rack B is operated by means of a lever, E, that is secured to the oase A by a tap-bolt, 71 the upwardlyextending arrn t' of the lever E engaging with a stud, j, which is secured to the horizontal arms d d of the frame B, and projects outward through an elongated slot,j, formed in the side of the casing, the aperture i in the arm t' being also elongated to allow for the necessary play.Y
The lever E carries a hand-piece, F, that is provided with a pin, k, arranged to engage with apertures k', formed in a rack, G, as shown, from which arrangement it will be seen that if the lever E is raised the frame B will be moved outward,and, conversely, if the lever E is depressed the frame will be drawn inward.
In order that the bars D D,whieh carry the teeth C, may be elevated or depressed as the necessities of the case require, I provide a lever, H, that is pivotally mounted between the horizontal strips c c, and connected by a link, I, with the bars D D, the upper end of the said link I entering the space between-the bars D, to which it is connected by a pin or bolt, yZ, while the lower end of the link is bifurcated to straddle the lever H, to which, as before stated, the link is pivotally connected. This lever H carries a hand-piece, K, that is provided with a pin, m, arranged to be brought into engagement with apertures n n, formed in a rack, L, that is carried by the sliding frarne B, the rack being secured to the inner face of two of the strips c d, as indicated.
Although in the construction shown and described the case A constitutes the knee, it will of course be understood that the case could be formed so as to be bolted to the standard or knee of any mill.
In operation it will be seen that the frame B may be advanced or retracted as the necessities of the case require, and it will be understood that when the lever E is moved so that its pin k is in the last or lowest hole the apparatus is then ready to dog the last board.
In Fig. 5 I illustrate a modied construc- Ico tion, wherein the lever E is provided with an upwardly-extending arm, N, instead of a removable extending arm, F, and wherein the lever H is provided with a bar, M, that is pivotally eonneeted to the end of said lever. The lower edge of the bar M is formed with teeth o o, that are arranged to be engaged by a catchtooth, O, that is fixed to the casing A. The object of this modified construction is to en,- able the Sawyer to manipulate the dog from a position in front of it.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a saw-mill dog, the eo1nbination,with the ease having an apertnred rack, the horizontally-movable frame carrying an apertured rack, and the teeth-carrying bars arranged between nprights of the said frame, ofthe le- 2o ver pivoted to said frame and connected to a link connected directly to the teeth-carrying bars, and the additional lever pivoted to said ease and connected to said frame, said levers having retainng-detents engaging with the racks of said case and rack, said lever carrying an upwardly-extending arm engaging with a stud which is secured to horizontal arms ofthe frame and projects outward through an elongated slot formed in the side of the ease, substantially as and for the purpose set forth.
2. In a sawmill dog, the eombi1iation,witl1 a ease, ofthe adjustable frame B, carrying adj ustable tooth-carrying bars D, and xnanipulat ing-levers E and H, the lever E being provided with an arm, N, While the lever H is provided with an arm, M, formed with teeth o, a eatohtooth, O, being1 formed on the ease, substantially as described.
