SPECIFICATION forming part Of Letters Patent N0. 632,000, dated August 29, 1899. Application filed April 8, 1899. Serial No. 712,229. (No model.)

To all whom, it may concern:

Be it known that I, FREDERICKVIV. SHET- TLEWORTH, a citizen of the United States, residing in Portland, in' the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in Stone-Sawing Machines, of which the following is a specification.

This invention relates to stone-sawing maio chines, the object being to ,provide an improved apparatus of this character simple in construction and durable in use and particularly effective owing to the improved organization and assemblage of the parts of such structure for the purpose for which it is designed.

In the drawings, accompanying and forming Apart of this specification, Figure 1 is a plan View of the main parts of the machine. Fig. 2 is a cross-sectional view taken in line zo w w, Fig. 1. Fig. 3 is a face view, on Van enlarged scale, of the means disposed at each end of the saw-frame for supporting the same. Fig. et is a side View of the parts shown in Fig. 3, looking from the right to the left. Fig. 5

is a perspective View of one end o f one of the saw-frame side bars and a part of the I-beam which supports the saws, thev dot-ted lines illustrating the recess into-which the I-beam istted when the parts are assembled. Fig. 3o 6 is Fig. 7 is a cross-sectional View taken in line y y, Fig. 3, and looking from the right to the left. Fig. 8 is a cross-sectional view taken in line .e 5, Fig. 3, and looking downward. Fig. 9 is a detail view of one end ot' a saw, showing its mode of assemblage with the I-beam. f Fig. 11 is a side view of the clamp connecting one of the trans- Fig. 10 is a top View thereof.

4o verse frame-bars with the I-beam. Fig. 12

isa top view thereof, and Fig. 13 is a viewv of a form of track-rolls dierent from those` shown in Fig. 3 and the other figures hereinbefore described.

Similar characters of reference designate like parts in all the figures of the drawings.

The saw-frame may bel supported by any suitable framework adapted for the purpose and usually comprises four upright posts or 5o beams, one adjacent to each corner of the frame. In the present instance this framea cross-sectional view taken in line as, Fig. 3, and looking from the right to the left.

work is shown comprising four upright beams or posts 2, secu red together at their lower and upper ends by cross-beams 3 and 4, respecp tively. 5 5 The saw-frame (designated in a general way by A) in 'the present construction,which may be its preferred construction, if desired, comprises two side bars 5, the major portions of which are preferably shown as tubular. Each 6o of these side bars is provided with squared ends 6, and in the present instance these squared ends are formed separate therefrom and are providedrwith tubular portions 6' for insertion into the ends of the tubular side bars, whereby a irm and rigid construction is provided. Theside bars are connected at their ends by transverse bars 7, and for this purpose the ends of the side bars are shown provided with concaved seats 9, into which 7o the transverse bars are fitted, they preferably being tubular. These transverse bars are bolted to the side bars in some suitable way. In the construction shown they are secured in position by tie-bolts 10, extending entirely through said side bars from end to end thereof, being secured thereto intermediate their ends by suitable bolts 12. Adjacent to each end of this saw-frame is disposed means for supporting the saw-blades, and which means 8o in the construction shown also constitutes a means for reinforcing the frame. In the present instance this means comprises a pair of I-beams 13, the ends of which are preferably fitted into recesses 14, (see Fig. 5,) formed for this purpose, this construction being readily permitted owing to the squared formation of the side-bar ends, and are secured to said side bars by bolted angle-plates 15. By this assemblage a saw-frame rigid and Vfirmin con- 9o struction is furnished. The saw-blades 16, of which there 'may be any desired number,

(shown herein as a gang thereof,) are secured to the I-beams by bifurcated bolts 17, the bifurcated ends 17 of which receive the saw- 95 blades, one extending above and the other below the I-bearn and being united at the outer side thereof by plates and nuts. Each of the saw-blades is preferably constructed to carry t two sets of teeth of different efficiencies, one roo set at each edge,'and for this purpose one edge (herein shown as the lower edge of each blade) is formed for the reception of steel teeth 18, Fig. 2, and which teeth may be of the formation and assembled in the manner shown and described in my Patent No. 618,524, if desired. The opposite edge is formed to receive diamond teeth 19, whereby in operation the same saw-blades can be used with either the diamond or the steel teeth.

The saw-frame-supporting means in the form thereof herein shown and described comprises a plurality of sets of rolls or roll-surfaces. (Shown herein as four sets, one set located adjacent to each corner of the sawframe.) For supporting these rolls suitable means is provided, which in the form shown comprises an adjustable support or traveling block 20, carried by each of the upright beams 2. Each of these blocks 20 is formed at its rear lside to slide upon a track or way 21, secured to the beam 2, Fig. 8, and for this purpose it is provided with a recess 22, having at one side thereof an inclined wall 23, its opposite side 24 being straight for the reception of the track 25, which is provided with a pair of inclined sides 26, one in engagement with the inclined wall 23 of the block and the other in engagement with the inclined wall 27 of a strip 28, having its opposite side 29 straight, whereby it is also adapted to fit into said recesses 22, being secured therein by a suitable fastening device, such as bolts 30. By means of this construction the formation and assemblage of the block and its way is permitted.

For adjusting the block it is shown provided with an internally-threaded sleeve 3l, through which extends a screw 32, secured at its upper and lower ends to the beam2. Each of these screws 32 may be suitably connected by gearing, (not shown,) whereby all may be operated simultaneously to raise or lower the blocks, andthe saw-frame supported thereby. Each of these traveling blocks 2O is provided with bearings 33 for the reception of roll shafts or journals, one of each set of which is so supported that the roll or rolls carried thereby can be adjusted toward and from the other shaft. In the construction shown each of these blocks is shown provided at its upper end with a pair o f journal-bearings having removable caps 34, while the lower end of said block is provided with a pair of split journalbearings.

The direct means for supporting the sawframe and for permitting the reciprocation thereof in a horizontal plane comprises a plurality of sets of rolls, (shown herein as four sets and designated in a general way by 13,) each set comprising a plurality of rolls or ro1lsurfaces so organized that the saw frame while supported for recprocatory movement in a horizontal plane will be prevented from lateral or sidewise play and also so organized that the greatest amount of support will be at the under side of said frame, and in the present construction each set of rolls comprises a three-point bearing.

At each end of the saw-frame is a transversely-extending shaft 35, mounted in the upper bearings 33 of the traveling blocks 20, on which a roll 40 is journ'aled adjacent to each end thereof, each end forming one of the rolls of its respective set.

Mounted in the lower bearing 33 of each block is a shaft 36, eccentrically supported within said bearings. (See dotted lines, Figs. 4 and 6.) Carried by this shaft isa two-point bearing 37, which may be formed as two separate and independent rolls or as one roll having two independent track-

surfaces

41 and 42. By the adjustment of this eccentricallymounted shaft, which is provided with holes for this purpose, it will be seen that the bearing 37 will be adjusted toward or from its coacting bearing 40. j By this means it will be seen that said bearing 37 is adjustable toward and from the bearing 40, owing to the eccentrically-mounted shaft.

The track-surfaces of the rolls shown in Figs. 1, 34, and 6 are V-shaped in cross-section, whereby the rolls have inclined peripheral flanges to prevent lateral movement of the saw-frame. For engagement with these rolls each squared end of the saw-frame side bars is provided with aseries of tracks (shown herein one, as 43, at the upper side, and two, as 44 and 45, at the under side, thereof) carried by suitable brackets 46, these tracks being so disposed that the edges thereof will it into the grooves of the rolls.

Instead of for-min g the rolls as j ust described and in order to materially decrease the frietion which is present in such a construction, each upper roll may` be formed as a flat roll 47, Fig. 13, coperatin g with a flat-faced track 43', carried by the frame side bar, while the lower twopoint bearing 37 may comprise one roll having a pair of right-angle anges 48 or a pair of rolls having a right-angle iiange at its outer side, said bearing coperatiug with a pair of fiat-faced tracks 44 and 45', carried at the under side of said side bar. In this construction it will be seen that the periph eries of the rolls (three in number) only are in frictional engagement with the tracks, whereas in the other there are six frictionsurfaces in each set of rolls. Furthermore, it will be seen that the right-angle Iianges of the lower rolls prevent lateral or sidewise movement of the saw-frame during its reciprocatory operation.

It will be understood, of course, that the tracks of each set are of sufcient length to permit the necessary reciprocatory movement.

Any suitable means may be used to reciprocate the frame on the rolls, such means having a power-transmittin g connector 50, which in the present instance is shown secured to one of the transverse bars 7 of the saw-frame. To prevent the buckling of this bar, it is shown clamped to one of the I-beams, and for this purpose a pair of split clamps 5l are shown secured to said transverse bar '7,iian ged bolts 52 extending therethrough and over- IOO IIO

eaaooo p a lapping the I-beam at its upper and lower sides. It will thus be seen that the means which clamp the I-bcam-namely, the boltsalso constitute means for clamping the split body of the clamp itself to the transverse frame-bar, whereby a portion of the strain imparted to the bar will be carried by the I- beam to which it is connected.

The operation of this improved machine will be readily understood without a further description.
