DRAG-SAW.

SPECIFICATION forming part of Letters Patent No. 248,200, dated October 11, 1881.

Y Application filed March 25, 1881. (Model.)

To all whom it may concern Be it known that I, MARION LAFAYETTE NICHOLS, ofCentre Township, in the county ot' Emmett and State of Michigan, have invented a new and useful Improvement in Sawing-Machines, of which thefollowingisaspecication.

My invention relates to a portable sawingmachine to be used for sawing trees or logs and adapted to be moved from place to pla-ce.

IO The invention consists in a novel construction, arrangement, and combination of a sawframe, the platform or stand, the gearing, and devices connected therewith, whereby provision is made for sawing in any desired direc- '15 tion, as hereinafter described.

In the accompanying drawings, Figure l is a side view ot an apparatus embodying my improvements. Fig. 2 is a top view of the same. Fig. 3 is an end view, with the saw-frame at 2O right angles with the platform or stand.

Similar letters of reference indicate .corresponding parts.

Arepresents a hase board or sill, upon which rests a double-inclined frame, B.

C represents the saw-carrier, consisting of a beam provided with two lateral arms, d d, near its front and reareuds on one side. It is pivoted on a vertical pivot or pin, E, extending upward from a supporting-block, G, and having 5o a thumb-nut, j', on its upper end, which is screw-threaded. The block Gis provided with trunnions g g, which work in bearings in the double-inclined frame B. Said block is also provide-d with an arc-shaped slotted bar, H, extending downward close to one side ot' the double-inclined frame. A flat-headed and screw-threaded pin or bolt, J, passes through the slotin the bar, and through the side ofthe frame, and is provided with a thumb-nut, i. 4o On the upper side of the beam C is a frame,

in which is jou'rnaled a shaft carrying a gear- Wheel, K, provided with a crank-handle, k. The wheel K gears with a pinion, L, on one end of a shaft, the other end of which carries a crank-wheel, M. This wheel is connected by a pitman, P, with a slide, S, consisting of a block arranged to slide on arod or bar having its ends secured in the arms d d. To the slide S is attached the rear end of the saw-rod R, which works through the forward arm, d, and 5o its front end has the saw-holder or stock T attached to it by a swivel-connection.

When the apparatus is to be used to saw vertically, either up or down, the thumb-nut z' is loosened so as to allow the sawcarrier to 55 swing on the trunnions g and be controlled by the operator holding the handle V with the left hand, while turning the wheel K with the right hand to operate the saw.

When the apparatus is to be used to saW 6o horizontally, as in felling trees and similar service, the saw-carrier is adjusted to the desired height and angle and then secured by tightening the thumb-nut i. The saw stock or holder T is then turned to the desired position to give the proper direction to the saw. The thumbnut f is then loosened, so as to allow the operator to control the lateral movement of the sawcarrier by means of the handleV and feed the saw to its work with the left hand,while operat- 7o ing the wheel K with the right hand.

By loosening both the nuts iandfthe sawcarrier C may have a universal motion imparted to it, and may be adjusted both vertically and longitudinally, while .the peculiar shape ofthe double-inclined frame B allows a motion of at least one hundred and eighty degrees. .t

Having thus fully described my invention, I claim as new and desire to secure by Letters 8o Patent- The combination, with theframeAB, of the saw-carrier C andthe trunnioned block Cr, the,t former pivoted on a pin, E, extending upward vfrom the latter, as shown and described.
