ATENT GEORGE D. HUNTER, OF BLOOMINGTON, INDIANA.
SPECIFICATION forming part of Letters Patent No. 663,078, dated December 4, 1900.
Application filed December 14,1899. b 740,308. (No model.)
To aZZ whom it may concern:
Be it known that I, GEORGE D. HUNTER, a citizen of the United States,residing at Bloomington, in the county of Monroe and State of Indiana, have invented certain new and useful Improvements in Gang-Frames for Stone Sawing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to an improvement in gang-frames for stone-sawing machines; and it consists in the construction and arrangement of parts hereinafter described and claimed.
The invention relates more particularly to that part of a gang for stone-sawing machines to which the power is applied for moving or swinging the gangs. It is customary in this type of machine to construct the saw-carrying members of angle or U-shaped iron and to bind the saw-lugs between two of such irons arranged back to back. It has been found that by continuous use these U-irons ultimately spread and permit the saw-lugs to move out of place.
My invention is designed to overcome the spreading of the channel-beams by lugs acting as a clamp preventing the U or channel beams from spreading or holding them in their proper relative parallel positions.
In the accompanying drawings I have shown an embodiment of the invention, wherein- Figure l is an end elevation of a section of an end of the gang-beam. Fig. 2 is a side elevation, and Fig. 3 is a top plan view.
In the drawings, A and A designate channel-beams, which are, as usual, of substantially U shaped formation. These beams are arranged back to back and are so spaced that the saw-lugs B can pass therebetween, the heads thereon overlapping the outer face or ends of the beams in a well-known manner.
0 designates a casting formed with two longitudinal channels I) b on each side and having at their lower and upper edges flanges D, which are formed with inwardly-extending tongues d, closely fitting against the outer edge or edges of the channel-beams, as shown in Fig. 2. This construction serves to prevent the beams from spreading and constitutes a seat for the flanges of the channelbeams. Passing through the channels 1) are the securing-bolts E, having at their outer ends the nuts or heads 6, seated in countersinks in the ends of the casting, while the opposite ends of the bolts pass through openings made in the ends of the channel-beams and are there capped with suitable nuts 0, thus securing the casting C to the channel-beam.
In the opposite faces of the casting O are formed the bearings F, in which the pivotal bar of the actuating mechanism or pitman is placed. These recesses are semicircular and the bearings are completed by the saddles or caps G, which are secured on the ends of the castings by the U -shaped bolts H, passing through perforations formed in the ends of the saddles and restingin curved seats formed in the outer faces or edges of the saddles, their ends passing through the channel 19 in the casting and through both of the flanges of the channel-beams, their extreme ends being capped with suitable nuts h. The caps or saddles are provided with corresponding semicircular recesses to complete the bearings, as stated.
The above-described construction prevents largely the warping of the beams at the center and effectively holds the beams against a transverse movement, which would have a tendency tocut or shear the bolts on the blocks.
The particular means for securing the members to the beams can be variously changed, as well as the form of saddle, and the bolts may be other than U shape, if desired.
Having thus described myinventiomwhat I claim as new, and desire to secure by Letters Patent, is-- 1. In a stone-sawing machine, the combination with the channel gang-beams arranged back to back, of a casting having projections overlapping the edges of the channel-beams, bolts passing through the casting and flanges of the channel-beams, a saddle on the ends of the casting and U-bolts passing through the casting around the saddle and through the channel-beam flanges, substantially as described. I
2. In a stone-sawing machine, the combination with the gang channel-beams, of a casting having projecting flanges at opposite sides ping the edges of the channel-beams, a saddle on the ends of the casting, means for se' curing the casting to the beams, and bolts secured to the flanges of the beams and engaging the saddle, substantially as described.
In testimony whereof I affix my signature in presence of two Witnesses.
GEORGE D. HUNTER.
