Application March :1, 1916, Ser a NO- 651,133

11 Claims- 1 My invention relates to certain improvements in vises and sine plates and they are a type that is precision built and the jaws open and close by means of a screw and handle, one of the jaws remaining stationary and the other slides back and forth. The vise is made to fit on the sine plate and is held securely in position by means of dowel pins and screws. The vise can also be turned universally on the sine plate and locked on any angle between zero and 360 degrees.

One object of the invention is to provide a simple way to clamp high grade tool WOlk in any angle desired. The sine plate has two open.- ings and can be blocked open with precision measuring blocks producing very accurate angles. Blocking open both sine ea-r openings at one time produces a compound angle. The vise can also be swiveled to any desired angle while both the sine bar openings are blocked open.

In the accompanying drawings:

Figure 6 is a view of m improved vise and compound angle sine plate. This view is a view of the whole thing completely assembled.

Figure 7 is a view of piece 18.

Figure 8 is a view of piece 33.

Pieces l8 and 35 are made of high grade tool steel which is hardened and drawn to its proper degree of hardness and is precision ground and precision lapped to a very closetolerance. Piece 33 is also sawed open on one side and nearly through on the other side with a grinding wheel, so that screw 2! can be tightened so that piece '33 is locked on piece [8 and can be unlocked by loosening screw 2! slightly. Also piece It and piece 33 could be made as shown in Figure 9.

Figure 9 is a view of pieces as including pieces l3 and 32. Piece 34 is made of high grade tool st which s hard ed and d aw t9 ts proper degree of hardness and is precision ground and lapped to the required size. Whereas pieces l3 are a snug fit on each end of piece 34 And the locking and unlocking device is produced by tightening and loosening set screws 32.

Piece I5 i m of hi h rade non hnkab e tool steel and is hardened and drawn to its proper degree of hardness and is precision ground and lapped to its required size.

Figure l is a side view of the vise and sine plate completely assembled.

Figure 2 is an end View of the vise and sine plate co pletel assembl d Figure v3 is a plan or top view of the vise assembled to the sine plate. The cutaway section of the vise shgws the graduation marks on the sine plate.

Figure 4 is a side elevation or view of the sine plate showing the opening blocked open with toolmakers precision blocks. The precision blocks are sometimes made to measure in millionths of an inch. When blocks of this type are used to block open the sine plate that produces angles to measure in degrees, minutes and seconds.

Precision blocks 23 and 24, Figure 4, are used to-block open the sine plates to the desired angle. The blocks are very accurate to within millionths of an inch. The center distance between these pins is supposed to 'bevery accurate also, say, to within one tenth of a thousandth of an inch, therefore, by blocking open the sine plate as shown in Figure 4. If the center distance is exactly.-5.000 inches that would produce a triangle of 30 degrees and no minutes and no seconds. In Figure 5. if the center distance between pins was 2.5000 inches that would also produce a. triangle of 30 degrees. This is proven by multiplying the sine of the angle of 30 degrees which is .5000" times the hypotenuse which equals .5000 times 2500 which equals 1. 250 inches as shown Figure 5. Figure 5 is an end view which shows the other opening which is bl ck d ope with hi h grade precision blocks.

As to the design and construction of the sine plate and vise all pieces and parts are made of a high grade nonshrinkable tool steel and are hardened and drawn to their proper degree of accuracy, which produces a beautiful piece of valuable art in high grade tool room work.

Jews

3 and 4 are held in place ,by screws 22 and dowel pins 2!. This means the jaws can be removed and reground.

- Places 24 and 525 are screwed and doweled on to piece 2, the sliding jaw, The sliding jaws move back and forth by screw 5 over the hardened and lapped square ways. 7

The cutaway section and the zero graduation 2D, is to use to swivel the vise to any desired angle on the sine plate looking at the graduation lines .on the sine plate as shown in Figure'3. The vise can be turned ,on the sine plate to any desired angle by removing one of the .capscrews 1.9 and both dowel pins I0, Fig. l. I

Piece .6 is a removable hardened and groundthreaded nut which is a force press fit into piece i, Figure Screw .5 is a hardened and ground and ped sc ew t at .fits in o piece 6- Piec and handle 8. Knob 9 fits into handle 8. Piece l5 has graduation lines cut on it as shown in Figure 3, and is precision ground and lapped to fit onto pieces [2, I3, and 34. Pieces [2 and I3 are so spaced in whole inches in length to allow the use of the sines, cosines and tangents, etc., of trigonometry tables; for instance, say 5 inches in 4 decimal points as thus 5.0000 inches. Pieces H are made as shown in Figure 9 and fit onto the ends of piece 34. The inside and outside diameters of

pieces

34 and 13 must be very accurate and must measure to within and not less than 4 decimalpoints or to within tenths of a thousandth of an inch. When the long or lengthwise side of the sine plate is opened, screws 32 can be tightened and lock the sine plate to the desired amount of t ghtness. When the bottom section or short sidewise side of the sine plate is opened screws 2! can be tightened on pieces 33 to allow for the exact amount of tightness required or vice versa. In other words set screws 32 may be used in the ends of both pins to tighten and loosen the opening and closing devices, or split bushings as shown in Figure 8, can be used on both the pins l8 and 34.

The center distance of the pins on the lower section of the short side must be a known size in inches. The reason for that is the plain, simple sine bar rule. so that the sine and cosines, tangents, etc. can be used, having in mind always that the center d stance is the hypotenuse of the angle and the center distance multiplied by the sine oi the an le roduces the amount of the measurement that the blocks should measure to produce the reouired angle. Pieces l3 are screwed onto piece l4 and piece 34 is screwed onto piece l5 thereby producing a hinge ty e design. Pieces 33 are screwed onto piece I6 and I8 is screwed onto piece l5 which also produces a hinge type design. The bottom of piece l3 may be serrated or corru ated if so desired.

The sine plate cons sts of 3 rectangular steel plates 14, I5 and I6, that are hin ed together by pins l8 and 34 that are fastened onto the ends and sides by the pins and bushin s. Bushings [3 are fastened onto one end of the top plate, the short pin 34 is fastened onto one end of the middle plate. The lone pin is fastened onto one side on the bottom of the middle plate. The long bushings 33 are fastened onto one side on the bottom of plate. These bushings 33 and I3 have ground and lapped holes in them that fit on the ends of the pins l8 and 34. Two set screws 32 fit in the ends of the pins l3. Two small capscrews 2| fit on each bushing 33. Bushing 33 is split open on one side and nearly through on the other side to allow for cap screws 2| to close the bushings around the pins.

Dowel pins 26 and capscrews 21

hold plates

24 and 25 onto the sides of vise jaw 2.

Pieces

24 and 25 fit onto the sides of the sliding jaw piece 2.

Set screw 35 screws into piece 2, and has a round point that fits into the groove on the end of the screw 5.

Pieces 36 are two hardened and ground and lapped fiat keys that hold piece 2 down onto the ways on piece I. Pieces 3'! are two cap screws that fit into

pieces

36, 38 and 2. Piece 38 is hardened and ground and lapped fiat keys that fit between

pieces

36 and 2 by capscrews 31. The two fiat keys are fastened onto the sliding vise jaw 2 and holds the vise jaw downwardly, how- '4 ever, not too tight as the vise jaw has to slide back and forth.
