WITNESSESI: INVENTUB a 'Inv UNITED STATES PATENT OEErcE.
LUKE BUZZELL, OF ST. JOHNSBURY, VERMONT.
IMPROVEMENT-IN SAW-MILL DOGS.
Specication forming part of Letters Patent No. 173,842, dated February 22, 1876; application filed November 19, 1875.
To all whom it may concern:
Be it known that I, LUKE BUZZELL, of St. Johnsbury, in the county of Caledonia and State of Vermont, have invented an Improvement in SawMill Dogs, of which the-following is a specification: Y
My invention consists of a dog for holding the log ou the head-block, mounted on a vertical screw having a quick pitch, so that it can be partly or wholly forced into the log thereby, and can be kept in so as not to Work loose by the jarring and shaking of the mill; and it is specially applicable to the (logging of frozen logsin which the ordinary dogs will not hold at all.
Figure l is a section of a log-carriage and log and side elevation of my improved dog contrivance. Fig. 2 is a horizontal section, taken on line w m of Fig. 1. Fig. 3 is a detail of the dog.
Similar letters of reference indicate correspondin g parts.
A represents the head-blocks, B the log, C
the dog, and D 'the screwon which the dog is tted so that it can be pressed into the log,
and be held securely after being pressed in. The screw is mounted in a strong bracket, E, and a bed-piece, F, resting on the carriage or on the head-blocks. In this case two dogs, a long and short one, are contrived in connection with one hub, in which the screw works, the long one being for holding the log until it is worked down too thin, and the short one for the rest 5 but it is immaterial whether one or two be used. The screw is also useful for unfastening the dog, and it also swings it around out of the wayof the saw after raising it out of the log.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with the screw D, of the sleeve, having a stud that works in the thread of screw, and two dogs, C C at right angles to each other, and of different length, as an for the purpose specified.
LUKE BUZZELL.
