SWING SAW Filed April 5, 1940 Patented Nov. 11, 1941 UNITED STATES PATENT OFFICE SWING SAW John H. Wilcox, Easton, Md. Application April 5, 1940, Serial No. 328,123
1 Claim.
This invention appertains to new and useful improvements in swing saws and more particularly to a swing saw frame.
The principal object of the present invention is to provide a swing saw frame provided with brace means for preventing the frame from twisting at the saw end thereof.
Other important objects and advantages of the invention will become apparent to the reader of the following specification.
In the drawing:
Figure 1 represents a front elevational view of the saw.
Figure 2 is a fragmentary enlarged perspective View of the saw frame and brace means.
Figure 3 is a fragmentary sectional view on the line 33 of Figure 2.
Figure 4 is a section on the line 44 of Figure 1.
Figure 5 is a side elevational view of one of the brace rods.
Referring to the drawing wherein like numerals designate like parts, it can be seen that numeral 5 represents the usual suspension shaft which extends through bearings 6 on a support I. Numeral 8 generally refers to the frame of the saw which includes a pair of side members 9-9 each having a bearing 10 at its upper end through which the shaft 5 is disposed, this shaft being provided with the usual drive pulley ll; Tie rods l2l2 are provided at the upper and lower end of the frame, these tie rods having threaded ends disposed through the side members 99 and on these threaded ends are the jamb nuts l3.
At the lower ends of the side members 9-9 are bearings [5 through which the saw shaft [6 is disposed, one end of the shaft I6 having the saw I mounted thereon. The pulley for the shaft I6 is denoted by numeral Hi.
In carrying out the present invention, brace means I9 is provided for preventing twisting of the frame at the lower end thereof.
This brace means consists of a plurality of elongated rods or wires each divided into a pair of sections 20 and 2|, and adjacent ends of these sections 20 and 2| are threaded for disposition into a corresponding turnbuckle sleeve 22.
It is also preferable that the remaining ends of the sections 20 and 2| be threaded and that the side members 9-9 be provided with substantially inverted T-shaped brackets 23 apertured to receive the threaded ends a of the sections 20 and 2|. Nuts 24 can be provided on the threaded ends a to act as stops.
It is preferable that these brace members be arranged in crossed relation. For instance, one of the brace members I9 will start from a bracket 23 on one side of the frame and. extend diagonally across to the other side of the complementary frame member 9 and this disposition of the brace members takes place from both sides of the frame and in a cross arrangement so that all four brace members intersect each other in crossed relation between the side members 9-9.
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having described the invention, what is claimed as new is:
In a swinging saw frame, a pair of parallel members each including a journal at one end to receive a power shaft and a bearing at the other end to rotatably support a saw, brace rods adjustably connected to said members adjacent each end of the members, a pair of diagonally extending tie rods adjustable as to length and crossing each other and adjustably and detachably secured to opposite faces of one of said members adjacent one of the brace rods and adjustably and detachably secured to opposite faces of the other member adjacent the other brace rod, and a pair of diagonally extending tie rods adjustable as to length and crossing each other and the firstnamed pair of tie rods and detachably and adjustably secured to one of the members adjacent one of the brace rods and detachably and adjustably secured to the other member adjacent the other brace rod and cooperating with the pairs of tie rods and the brace rods in reinforcing the members to prevent the latter from twisting out of position by stress during the use of the saw.
