(CL-14H 4 Claims.
This invention relates to saw feeding apparatus and is designed primarily as a means whereby a circular saw can be moved forwardly or backwardlyas desired and relative to thework by means of a simple but emcient mecha nism under constant. control of the operator, and
without interfering with the rotation of the saw.
A further object is to provide a means by 1 which the shaft of the saw can be utilized as a feeding element for shifting the saw into or out of position.
With the foregoing and other objects in view which will appear as the description proceeds, .the invention-consists. ofcertain novel details of 1 construction and combinations ofparts hereinafter more fully described and pointed out in the claims, it being understood that changes may be .made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
In the drawing, which is a plan view of the apparatus, the preferred form of the invention has been shown.
Referring to the drawing by characters of ref- "erence, I designates a suitable supporting frame provided with guide rails I. A carriage I is mounted for movement within the frame and has the cable It will be drawn taut while additional slack will be supplied to the cable II. As a result of this action the convolutions II will be tightened on the shaft I and said shaft will therefore be caused to wind cable I! therearound so that the carriage will be moved toward the fixed end ll of the cable. By shifting the crosshead to its other extreme position, however, the
convolutions. i! will be loosened and cable It rendered slack while cable I! will be drawn taut and its convolutions willbe tightened. As a result, continued rotation of the shaft I in the direction indicated by the arrow will result in the transverse axles 4 on which aremounted wheels I adapted to travel along the rails so that the carriage will be properly guided.
Bearings 8 are mounted on. the carriage and iournalled therein is a shaft I of a circular saw This shaft has one or more pulleys I whereby motion may be transmitted thereto through one or more belts II from the pulleys H of a motor II, the motor being connected to and movable with the carriage and, in the structure illustrated, being suspended therefrom.
A cross-head I3 is plvotallymounteei between its ends on frame I as indicated at H and, in the structure illustrated, has an arm or handle II extending therefrom. To the respective'ends of .this cross-head are attached'cables l8 and II the opposite ends of which arefastened securely to the frame as shown at It; Cable I8 is wrapped carriage 8 being moved toward the cross-head due to the fact that cable 81 willbe wound on the shaft .1. Thus by manipulating handle II and cross-head l8, themovement of the carriage 3 in either direction can be controlled readily. Obviously as the carriage is moved,,the saw and the motor will also be moved therewith.
What is claimed is i 1. The combination with a movable carriage,
and a frame for supporting and guiding theisame. of a shaft journalled on the carriage, a circular saw carried by the shaft, cables anchored at one end to the frame and wrapped in opposite directions respectively about the shaft, and means on the frame and connected to the cables for placing either of said cables under tension.
2. The combination with a movable carriage,
and a frame for supporting and guiding the tension, said means including a pivoted crossin one direction about the shaft 1 while cable ll is wrapped in the opposite direction.
Under normal conditions the cables are slack so that the shaft 1 can revolve freely within the convolutions II and 20 forming parts of the respective cables.
Assuming that the'shaft 1 is rotating m the I direction indicated by thearrow, it will be obvious that when the cross-head I3 is shifted to the position indicated by broken lines in the drawing,
ing the cross-head' same, of a shaft journalled on the carriage, a circular saw carried by the shaft, cables anchored at one end to the frame and' wrapped in opposite directions respectively about the shaft, and means on the frame and connected to the cables for placing either of said cables under other ends of the respective cables, and means for swinging the cross-head on its pivot for tightening either of the cables about the shaft.
4. The combination with a structure havin guides, and a carriage mounted for back and forth sliding movement relative to the frame and to the other ends of the respective cables, and means for shifting the cross-head to tighten either of the wrapped portions of the cables thereby to move the carriage in either direction 5 relative to the structure.
