UNITED STATES PATENT OFFICE.

FREDERICK ROBBINS LANE, OF VVOODBOROUGH, ENGLAND.

HORIZONTAL SAWlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 420,348, dated January 28, 1890.

Application filed July 11, 1889. $eria1No. 317,190. (No model.) Patented in England March 16, 1889, N0. 4,6 38.

To all whom it may concern.-

Be it known that I, FREDERICK ROBBINS LANE, engineer, a subject of the Queen of G1 eat Britain, residing at Woodborough, in the county of \Viltshire, England, have invented certain Improvements in Horizontal Sawin g-Machines, (for which I have previously obtained Letters Patent in Great Britain, dated March 16, 1889, No. 4,638,) of which the following is a full, clear, and exact description.

This invention relates to steam, gas, or water power horizontal saw-frames, the object of the improvement being to render such frames portable byconstructing them in a number of parts, which may be readily detached for transport and re-erected when re- ,quired; and it also relates to the driving mechanism, with the object of simplifying the mechanical arrangements for reciprocating the saw with comparatively n0 vibration and less power required, the saw being capable of being reciprocated at a much higher speed, and thereby doing a larger amount of sawing, also enabling it to cut veneers.

In the accompanying drawings, Figure 1 represents a front elevation of a horizontal sawing-machine constructed according to my invention; Fig. 2, a plan view thereof; Fig. 3, an end elevation, and Fig. 4 a partial section taken through line as an on Fig. 1.

Referring first to the construction of the structural frame, A represents two rails or sleepers, which may be of either wood or metal, and which are laid on or sunk into the ground at a suitabledistance apart in a direction at right angles to the line of the saw. Astoutbeam of timber B is supported by these sleepers, and is mortised. toward each end to receive the tenoned ends of two vertical posts C, the upper ends of the .posts being surmounted by metal caps O,

tal beam B, and the other two of each set connect the caps O to which they are attached, respectively, to the ends of the rails A, which support the said beams.

The saw E is mounted in a rectangular metal frame composed of two vertical pieces E, connected by nuts e to the two horizontal rods E the saw being stretched between the lowerends of the pieces E by means of the usual clamps e and nuts e To the vertical pieces E are screwed or' bolted slide-blocks E, which are free to work in slides F, fixed to the saddle G, which slides upon the posts 0 on the slides 0 and can be raised or lowered by means of the screws H, which work through nuts h, attached by brackets h to the saddle G, and are squared at their upper ends to receive a screw-key or spanner or other suitable gearing.

The driving mechanism consists of a disk J, mounted on a shaft J',which works in bear- 7o ings formed. on or attached to the saddle G.

The shaft J also carries fast and loose pulleys K, for the driving-belt L to travel around,

anda fly-wheel M. On the face of the disk J is a swivel-stud j, which works within a yoke formed by two vertical bars N, which are bored at their ends, so as to slide upon the rods E of the rectangular metal frame,

being kept at a suitable distance apart by collars n and clamped by nuts n The rods E, as will be observed, are thickened in their middle portions, such thickened portions being screw-threaded. By this arrangement the nuts a can slide over the end portions of the rods E, and thus a considerable amount of screw-threading is dispensed with. It will be obvious that as the disk J rotates, the stud j, acting alternately on each side of the yoke N, will impart a reciprocatory motion to the rectangular frame, and consequently to the 0 saw E, the extent of such motion depending on the distance of the stud j from the center of the disk J. The material to be fed to the saw is mount;

ed on one or more trolleys running on rails and worked by chain-feed or other suitable form of gearing.

Vention,WhatI claim as new, and desire to sedescribed, and illustrated in the accompanycure by Letters Patent, is ing drawings.
