GEORGE E. CAMPBELL, OF CHATTANOOGA, TENNESSEE, ASSIGNOR TO THE WI-IELAND COMPANY, OF CHATTANOOGA, TENNESSEE, A CORPORATION OF TENNESSEE.
DOUBLY-SUPPORTED TOP SAW GUIDE.
Application filed April 12, 1922.
To all whom it may concern:
Be it known that I, GEORGE E. CAMPBELL, a citizen of the United States, residing at Chattanooga, in the county of Hamilton .1 and State of Tennessee, have invented certain new and useful Improvements in Doubly-Supported Top Saw Guides, of
which the following is a specification.
This invention relates to an improvement in in a doubly supported top saw guide.
Heretofore, it has been the practice to support the top saw guide from one column only of the mill. This improvement consists in a guide supported and movable upon 15 the two columns located on either side of the saw-wheel.
In other words, the gist of this invention is to make provision for raising and lowering a saddle slidably mounted on each of the two columns of the mill exactly together, all of which may be done by any approved mechanical means, although a definite one has been shown, and will be described, although it is understood. that it is merely illustrative of a feasible form of construction.
In the accompanying drawings:
Fig. 1 is a view in side elevation;
Fig. 2 is a front view;
Fig. 3 is a top plan View.
The numerals 1 and 2 represent the upper and lower wheels for the band-saw S, they being supported on suitable bearings through the shafts or axles 4, as is well understood.
Saddles A and B are slidably mounted upon the columns, and they are supported and operated by chains 8 which are carried around the wheels 9, supported at the upper ends of the columns, and thence they extend to the wheels 10 on the shafts 11, upon which wheels the chains are wound, both ends of the chains being attached to the saddles. These shafts have worm-gears 12 keyed on their outer ends, and worms 13 on the shafts 14 are meshed with the worm-gears and transmit motion thereto.
The shafts 14 have miter-gears 15 on their opposite ends which mesh with the mitergears 16 on the cross-shaft 17 and the cross-shaft 17 has a bevel friction 18 on one end, and the friction cones 19 and 20 keyed Serial No. 551,828.
on the shaft 21 are arranged to engage the friction l8 alternately as controlled by the hand-lever 22 for reversing the cross-shaft 17, and through it the shafts 14 accordingly as the saddles A and B are to be raised or lowered. The shaft 21 has a sprocket 23 thereon by which it is driven through the chain 24 from the sprocket 25 on the shaft 26.
The saddles have attached thereto the depending swinging arms 27, and these carry the cross-bar 28 which also composes the inside saw-guide; and to the cross-bar the outside saw-guide 29 is secured.
In this way provision is made for raising and lowering both ends of the saw guide simultaneously and uniformly, and for alway supporting it alike from both columns instead of from one only.
I claim:
1. A top saw guide including two vertical columns, saddles slidably mounted thereon, depending arms pivoted for swinging movement on said saddles, a saw guide, the opposite ends of which are pivotally support ed by the arms, and means for raising or lowering both saddles uniformly.
2. A top saw guide including two vertical columns, saddles slidably mounted thereon, depending arms pivoted for swinging movement on said saddles, a saw guide, the opposite ends of which are supported by the arms, means for raising or lowering both saddles uniformly, transmission shafts, gears and friction means for controlling the simultaneous and uniform raising and lowering of the saddles.
3. A top saw guide including two vertical columns, saddles slidably mounted thereon, depending arms pivoted for swinging movement on said saddles, a horizontal saw guide carried by said arms, wheels rotatably mounted on said columns, means carried by said wheels and attached to said saddles for raising and lowering said saddles, and means for rotating said wheels.
4. A top saw guide including two vertical columns, saddles slidably mounted thereon, depending arms, pivoted for swinging movement on said saddles, a saw guide carried by said arms, gear wheels rotatably mounted on said columns, chains carried by said gear wheels and connected to the saddles, and means for rotating said gear wheels for simultaneously raising or lowering the saddles, said means comprising gears connected with the gear Wheels, shafts having Worms on one end meshing with said gears, and bevel gears on the opposite end for meshing with bevel pinions on a transverse shaft, a bevel friction on the transverse shaft, friction cones for driving the bevel friction, a
lever for moving the friction, cones into and out of engagement With the bevel friction, and means for driving the friction cones. 10
In testimony whereof I affix my signature.
GEORGE E. CAMPBELL.
