To all whom it may concern.' i

Be it known that I, HTRAM l). MORRTLL, a citizen of the United States, residing at Northfield, in the county of lVashington and State of Vermont, have invented certain new and useful Improvements in Stoneworking Tables; and do 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 a Jertains to P make and use the same.

This invention relates to an improved stone working table and one object of the .invention is to provide a table so constructed that it may be tilted to a desired angle and to further so construct the table that the uppersectionk thereof may be rotated with the table either in a tilted or horizontal position, thus permitting a block of stone to be easily handled and cut.

Another object of the invention is to so constructy this table that a portion thereof may be adjustably supported at one side to 'permit the table to be leveled when in a vide an improved means for adjustingthe position of the table, the adjusting means including cam elements mounted upon shafts which are rotated by a power shaft carried by the base.

Another object of the invention is to so constructthis table that the latch for releas-v ably holding the table against rotation may be adjusted when in engagement with the table and thus the table given a slight adjustment after being rotated to approximately the desired position.

Another object of the invention is to provide a table which will be strong and durable and simple in operation.

` This invention is illustrated in the accompanying drawings, wherein: f

Figure 1 is a. top plan view of the improved table, certain portions of the table and operating mechanism being indicated by dotted lines.

Figure 2 is a view showing the table in end elevation.

Figure is a side elevation of the improved table. i

Figure 4f is a vertical sectional view through the table taken` along the line 4 4 of Fig. 1.

Figure 5 is a horizontal sectional view through the table taken along the line 5 5 Of Fig. 2. Y

Figure 6 is a sectional view taken* along the line 6 6 of Fig. Y

Figure 7 is a perspective view of a bar engaged one of the cam wheels of the adjusting mechanism and serving as a bracing bar. y

.Figure 8 is a perspective View of a bracket engaged by a second cam wheel.

This improved table is provided with a foundation having side beams f1 and cross beams 2, thus providing a substantially rectangular foundation. .Bolsters 3r rest upon the side'beams 1 and are connected by a cross .bar al and also by a casting or angle bar having ears G at its ends so that screws or other fasteners 7 may be passed through these ears andinto the reduced end portions of the holsters 3. It will thus be seen that the bolsters will rest upon the foundation and one may be moved vertically so as to permit of adjustment for leveling the table transversely.

In order to raise one side of this base formed by the holsters 3 and cross bar 4;, there has been provided a shaft 8 which extends longitudinally of the foundation and is rotatably mounted in hearings 9 carried by the cross beams 2. This shaft 8 carries cam disks 10 and 11, the cam disk 10 being positioned at one end of the shaft 8 where it may engage the thickened portion 12 of the casting 5 and the cani disk 11 is positioned upon the shaft 8 where it may engage the outstanding abutment lip 13 car ried by the bracket 14. This bracket 11 is. provided with a base 15 through .which fasteners pass to connect the bracket with one of the holsters 3 and the outstanding lip 13 is braced by a web 16 thus preventing danger of the lip being broken off. It will thus be seen that when the shaft 8 is rotated to swing the disks 10 and 11 upwardly, these disks will engage the lip llof the bracket 14e and .the thickened portion 12 ofl the casting 5 and thus raise one side of the base. In order to rotate the shaft S, this shaft has been provided with a gear wheel 17 having its teeth cut to engage a worin 18 carried by a shaft 19 journaled in the bearing of the bearing bracket 20'. This bearing bracket 2O is secured upon Loneof the cross bars 2 as shown in Figures 5 l.and 6 and will be securely held in place thus preventing the worm 18 from moving out of engagement with the worm gear 17. ,A hand wheel 21 is provided for the shaft 19 so that this shaft can be easily rotated.

The table is provided with a lower section 22 and an upper' section 23 having bearingY :sleeves 24 and v25 Amounted as shown in Fig.

4 and receiving a bolt or pivot pin 26 so that the upper table section 23 may be rotated upon the lower table section.

Rings

27 and 23 which forni-bearing races are carried by the

table sections

22 and 23 and bearing balls 29r are positioned between these rings as shown, thus permitting the upper table section to rotate very freely.V ltis desired to permit the upper table section V33 and has lits lower end portion/provided with an opening receiving the linger 34 of the lever 35 which lever is pivotally mounted beneath the arm and engaged by the spring 3G so that it will be yieldably held in the position of F ig. 4 with the pin 31 extending through an opening of one of the side ears 30. An abutment block 37 is carried by this arni 33 and positioned between the bearings 3Sof the bracket 39 so that when the pin 31 is positioned in the opening of one of the ears 30, the adjusting screws 40 may be turned in their bearings 38 and the table given ar slight rotation thus bringing the stone into the proper position in case itis not placed straight uponthe table. lt will thus be seen that the upper table sectionl may be turned to approximately `the proper position and a final adjustment given which will bring the stone into the desired posi` tion. This upper table sectionvis formed in layers as shown, the lower layer having the sleeve 25 embeddedtlierein and upper layer carrying corner blocks-41 upon which the stone will `rest and having its central portion cut out to provide a pocket 42 so that the securing nut 43 may be applied to and removed from the bolt or pivot stein. 2G.

ln order to permit of the table being tilted from a horizontal position to an inclined position, the table has its lower section provided with bearings 44 through which ei;- tends a shaft 45 mounted in beaiings 46 carried by the bolsters 3 ofthe base. Therefore, the table will be pivotally mounted and may be tilted to the desired angle. In order to support the table in a horizontal or tilted position, there have been provided

cam disks

47 and 48 which are mounted upon

shafts

49 and 50 mounted in

bearings

51 and 52 carried by the holsters` 3, the bearings 51 being mounted adjacent one end of the base and bearings 52 being mounted upon the reduced end portion of the side beams adjacent the cross bar or casting 5. From an inspection of Figs. 3 and 4, it' will be seen that the cam disk 47 extends in an opposite direction to the cam disk 48 and that therefore when the

shafts

49 and 50 are rotated, the disks 47 will be swung upwardly while the disks 4S are swinging downwardly. In order to impart rotary movement to the shafts, there has been provided a shaft 53 journaled in the bearing 54 of the bearing bracket secured to one of the side beams 3. This shaft 53 which Yis provided with a turningwheel 56 carries worms V57 which engage the worm gears 5S mounted upon the

shafts

49 and 50. By turning the shaft 53, rotary movement will thus beV imparted to the shafts 49 and50.

Then this improved table is in use, it is set up with the

cani disks

47 and 48 in the posit-ion shown in Figures 3 and 4. The table should then belevel. lf it is found that one side is lower than the other, this can be cured by shaft 8 and thus raising or lowering the side of the base carrying the bracket 14. `After the table has been leveled, the stone will be put in place and one side `can be dressed. lf it is found thatthe stone does not tit properly upon the table, a slight adjustment can be made by means of the set screws 40. After the stone is in place, the table will be tilted to bring the stone into the proper position for cutting the beveled face, and after one side has been dressed, the latch will be released and the table given a quarter or half turn. Thelatch is again locked and the second side of the stone dressed. It will thus be seen that the table may be placed at anyv desired angle and the stone easily dressed with all sides easily cut at the same level.
