PORTABLE R'AIL-SAWING MACHIINE.
SPECIFICATION forming part of Letters Patent No. 243,595, dated June 28, 1881. Application filed hlarch 21, 1881. (Model.)
To all whom it may concern:
Be it known that I, JAMES MCKINNEY, of Saltillo, in theeounty of Lee and State of Mississippi, have invented a new and useful Improvement in Portable Rail-Sawin g Machines,
of which the following is a specification.
My invention relates to a portable machine for sawing off the mashed and bnrred ends of railroad-rails, instead ofchipping them oif with a hammer and chisel, as heretofore.
The invention consists in a novel construction, arrangement, and combination of a frame for attachment to the rail, and a frame suspended therefrom and carrying a rail-saw and devices'for operating it.
In the accompanying drawings, Figure 1 is a side view, and Fig. 2 is a rear iew, of a machine embodying my improvements.
A represents an iron frame of oblong. form, provided at its lower end with hooks B on its front side, adapted to grasp the overhanging edge of the tread of a rail, It.
Extending from the rear side of the lower end of the frame i an arm, 0, which is bent downward and has a ring, 0, at-its lower end.
I) represents an iron frame, also of oblong form, but smaller than the frame A, so as to readilyswingtherein. Itsupperendishinged to the upper end of the frame A by means of lugs a d and a rod,f, so that when the frame A is in an upright position the frame D-can swing therein.
The frame D is provided with a handle, G, for operating it, and its motion is limited by a curved arm, H, extending rearward from the frameA, and having a shoulder, h, at each end.
In the frame D is journaled a shaft, J,which carries a gear-wheel, K, and is provided with a crank, t. pinion, L, which, in turn, meshes into a gearwheel, M, attached to one end of a shaft, 1?, journaled in the lower part of the frame D, and carrying at its'other end the saw S.
The wheel K meshes into an idler- From a hookat the upper end of the frame A a bucket, Q,is suspended over the saw, for the purpose of allowing water to drip therefrom onto the saw,in order to keep it from heat- The apparatus is used as follows: The hooks B are hooked under one side of the railroadrail R, and the frame A is placed in an upright position with the arm' 0 on the side of the rail opposite the hooks B. A crow-bar is then passed through the ring 0, so that its point en-l gages with the edge of the rail, while its weight beyond the ring 0 is suflieient tohold the frame in place. The handle G is held by the left hand, and the saw fed up to its work thereby,.while the crank t is turned by the right hand to rotate the saw, through the gearlug.
Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. A portable rail-sawing machine possessing the following elements, namely: ,astationary frame adapted to be attached to a railroadrail, and a swinging frame suspended from said stationary frame and carrying a saw and devices for operating it, substantially as and for the purpose herein described.
2. In a rail-sawing machine, a frame, A, provided with hooks B,'and an arm, G, having a ring or eye, 0, for connecting the apparatus to a rail, substantially as herein described.
3. The combination, with the swinging frame D, provided with the handle G, and carrying the saw and driving-gear, of the curved arm H, extending from the stationary frame A, and provided with the shoulders h, substantially as herein described.
JAMES MCKINNEY.
