SINE-JBAR.

Lg lldAldll.

Specification of Letters Patent.

Patented Jul 1, 19191..

b all whom it may concern Be it known that l, ABRAHAM SoHAonrA'r, a citizen of the United States, residing at Brooklyn, borough of Brooklyn, city of Greater New Yorlgand State of New York, 1

have invented certain new and useful llmprovements in Sine-Bars, of which'the followingis a specification.

My invention relates to precise instruments adapted for determining angles or the,

inclination of angular surfaces more accurately, by means of a sine bar of predeter- 1 mined length pivoted upon a blocker 'support, and having the axis of the pivot thereof located a predetermlned distance above a definite horizontalplane, andhas for its primary object to provide an improved construction of the same, whereby saidbar may be adjustedand clamped to said block at a plurality of points.

A further object of my. invention is to provide said bar and its block or support with means whereby work to be operated on may be clamped thereto in definite relation to said bar when the latter is adjusted to a predetermined angle, whereby said work may be ground or machined with absolute accuracy at any desired angle.

My 1nvent1on embodies certain minor details of construction in respect to the sine.

bar and its method of adjustment and of re tention in any adjusted position, as herein after will be pointed out and claimed more definitely, reference being had to the accompanying drawing, in which v Figure 1 is a perspective view of my 1mproved block and attached slne bar, the latter being shown in an adjusted position, and

a piece of work'being shown fixed to said block in proper relation to said sine bar.

Fig. 2 is a view similar to Fig. 1, the block being shifted a quarter turn on its supporting-base, and the sine bar being shown adjusted by means of suitable. gage blocks placed under the movable end of the same. Fig. 3 is a sectional view taken through the pivotal point of the sine. bar and its block, showing the means of attachmg the,

sine bar pivotto said block.

Fig. 4 is a face view of one corner of the block showing the slot thereinat that portion, and the movable endof the sine bar in register with said slot, said sine bar being partly broken away, a

at 6 toengage responding parts in the several views.

In the said drawing, the reference numeral 1 denotes the metal block to'which the sine baris pivoted, and 2 said sine bar, the latter being pivoted to said: block at 3.

Formed in said block on the are of a circle struck from the pivot 3 is a through slot 4, the same bein disposed at a distance from said pivot 3 slightly shorter than the length of said sine "bar 2, and with which is engaged a bolt 5, passing through said sine bar and slot, said bolt being headed at its. inner end the inner face of the block 1, as best. seen inFig. 5. That portion of the bolt 5, which lies in the slot 4, is enlarged illustrating uponopposite sides of its center at 7 to engagethe sides of said slot to prevent rotation of-said .bolt therein. The outer threaded end of said bolt 5 passes through a sleeve 8, which also projects through the aperture in the sine bar and contactswith the block 1, and these parts are adapted to be clamped in any ad usted position by means of a not 9, threaded onto the outer end ofthe bolt 5 and slotted at 10 to receivea suitable manipulating tool.

The-end of the sine bar 2 pivoted at 3 is connected thereto by means of a bolt 11,-

which passes through a sleeve 12 similar to I the sleeve 8 into the block 1, where it is retained inposition by any suitable means, such as a screw-bolt 13, passing through the side of t e block 1 and engaging a groove'14 in said olt 10. The outer end of said bolt 10 is screw-threaded to receive a clamping nut 15,.similar in construction to the clamping nut 9. i

The length of the slot. 4 is such that when the sine bar is shifted on its pivot to one extreme of movement, its side face will lie exactly parallel with the adjacent side face of the block 1, whereas when posi te extreme of movement in said slot, its opposite side face will lie parallel with the adiacent side face of the block 1.'

The face of the block 1 is provided with a plurality of through apertures 16 adapted to to receive one or more bolts 17 tor adjust-ably moved to its opstood that the distance from the pivotal cenin said positionby' means of clamp nuts 9,

ter 3 of the sine bar-to the lower edge of the block 1,"as well as the distance from said center 3 to the center of the bolt 5, which moves m the slot 4, \being constant, the required height of sleeve 8 from the edge of block 1 may be determined by the following formula: I

said formula being read on Fig. 6.

In actual operation, when it is desired. to

grind one face of a piece of work along'a line at a desired angle, the block 1 is placed upon its support in the position shown in Fig. 2, and the desired angle of adjustment of the/sine bar 2.-is obtained by-means of .gage blocks 20, or by means of a suitable elght'gage, whereupon said bar. is clamped and 1-5. The block 1 then is turned at a right angle to its former position, or to the to be ground is positioned against the sine bar and is clamped in said position by means of block 18 and bolts 17, as shown. In this position the face of the work 19 may be ground or machined in a manner readily understood.

Inorder that I the surface of the block around the aperture through which the bolt 11 passes may not present any bur or raised. portion, I form in said surface around saidaperture a slight an'nular depression 22.

-. Having thus described my invention,

what I claim as new and desire to secure by Letters Patent, is: j 1. A device of the class described, comprising a supporting block having a slot therein struck on the arc of a circle, a sine bar pivoted near one end. to said block atadjusted position at its pivotal point.

is struck, means carried by'said sine bar and engaging through said slotfor clamping the free end of said bar in any adjusted position and means for clamping said bar in any 2. A device ofthe class described, coinprising a supporting block, a sine bar, a pivot bolt provided with an annular groove and passing through said sine bar and into said'iblock, and a screw bolt passing .into

said block and engaging the annular groove in said pivot bolt to retain the latter against withdrawal.

3. A device of the class. described, comprising'a supporting block, a sine bar having a pivot aperture therein, a sleeve disposed in said pivot aperture, a pivot bolt passing through said sleeve and into said block, a,

screw bolt passing into said block and engaging said pivot bolt to retain the latter against Withdrawal, anda clam ing nut on said pivot bolt for retaining sai bar in any adjusted position.

4:. A device of the class described, comprising a supporting block having a through slot therein struck on the arc of acircle, a sine bar pivoted near one end to said block j pat the center of said circle, a sleeve in said position shown in Fig. 1, andthe work 19 bar at the point where it registers with said slot, a bolt'passing through said sleeve and slot and headed on its inner end, said bolt at 80 the point where it engages said slot being enlarged on opposite sides of its center to prevent rotation therein, and a clamping nut engaging the outer end-of said bolt to retain said parts in any adjusted position.

5. A. device of the class-described, comprisin a supporting block provided with a plurali yof apertures, a sine bar pivoted thereon near one end, and means adapted detachably to engage through any of said apertures for clamping work in relationto said sine bar.

Intestimony whereof, I hereunto set my hand this 31st day of May, 1917.
