VICTOR J. .EMERY, OF WOLLASTON, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO MELLEN N. BRAY, OF BOSTON, MASSACHUSETTS.
GRINDER.
To all whom it may concern:
Be it known that I, VICTOR J. EMERY, a
citizen of the United States, and a resident of Wollaston, in the county of Norfolk and State of Massachusetts, have invented an Improvement in Grinders, of which the following description, in connection with the accompanying drawings, is a specification,
reference 'to the following description taken in connedtion with the accompanying drawing, wherein Figure 1 1s a side view:- of a device illustrative of my invention, Fig. 2 is an end View from the left of, Fig. 1, and Fig. 3 is a section on the line 33 of Fig. 2.
Referring to the drawings and particularly to Figs. 1 and 3, the embodiment of my invention there shown comprises a shaft 1 of any convenient length. On this shaft in planes transverse thereto are mounted the spaced disks 2 and 3 as shown at the left of Fig. 3 connected by'the pins 4 which are supported at their ends by the disks. Be-
tween the disks and pivoted on. the pins are are shaped holders 5 in any desired number, four being shown, which carry at their free ends (see Fig. 2) the abrading members 6 which may conveniently be blocks of carborundum or the like. These abrading members .may be mounted as shown in Fig. 2 in open sided slots 7 or recesses in the members 5 and held by any suitable means as by set screws 8 bearing against the shoes 9 disposed in recesses in the blocks 6, The holders 5 may swing in and out ontheir pivots to vary the distance of the outer or abrading faces of the blocks from the shaft. When the grinder is properly adjusted these faces all lie on a circumference the center of which is on the axis of the shaft 1 and, if the shaft 1 is rotated,
' each block will move in a circular path or orbit about said axis and grind uniformly any surface presented thereto. .To more ac-' curately present the faces of abrading blocks to the arc of the circumference and to facilitate the action thereof on the work, the
Specification of Letters Patent.

blocks are-preferably raked or inclined to radial lines as shown in Fig. 2. f
To hold the abrading members in operative position and to adjust the same each holder'5 (see Fig. 2), is acted. upon by a spring 10 which tends to swing it outwardly on its pivot. This spring is here shown '(Fig. 2) as a helical spring seated in a suitable recess 11 in the shaft 1 and bearing against the outer end of the holder 5. The holders are moved to and held in any desired position against the resistance of the springs by adjustable detents which may take the,form of longitudinal levers 12 pivoted on pins 13 transverse to and equidistant from the shaft 1, which pins may conveniently be mounted as shown in suitable ears formed on a collar 14 on said shaft. One end of eachof these levers extends through a suitable opening'in the disk 3 and is engaged with a holder member 5 in any desired manner as, for example, by entering a recess therein (see Fig. 3); It will be obvious that when the opposite end of the lever is moved inward toward or outward from the shaft the holder will be allowed to move outwardly therefrom under the action of the spring or will ,be pressed inwardly toward the shaft against the resistance of the spring, as'the case may be,
and it will further be apparent that, if each lever is moved the same distance, the abrading blocks 6 will all be adjusted to the circumferen'ce ofthe same circle.
For this purpose I have provided means whereby the ends of all the levers may be uniformly moved outwardly from the shaft to adjust the holders and in the form here shaft 1 carrying with them the holders 5 and contracting the circle on which the abrading blocks lie. Similarly, when the sleeve 15 is retracted toward the right, the ends of the levers will be allowed to swing outwardly, each to the same extent, under the thrust of the springs 10 and the abrading members '6 will lie on the circumference ofa larger circle than before. Becauseof the movement of the levers by means of a screw a very delicate adjustment can be made.
In the use of my device the abrading members are adjusted to any desired posinatively the shaft might be held in the tail.
stock and the work rotated. I
The mounting of the abrading blocks is such that they are positively held by the detents or levers against outward movement and there is therefore no danger of removing an excessive amount of material. At the same time they are always resiliently pressed against the work and so can function to the best advantage. If any unusual resistance is encountered they may yield inwardly without imposin any strain on the device.-
Consequently un nished articles with rough and uneven surfaces can be worked with safety and quickly brought to final form. The springs 10 will also absorb vibration and prevent'chattering.
When necessary the abrading members are easily. removed by releasing thedetents 12 and swinging the holders but from between the disks 2 and 3. The set screws 8 may then'be loosened and the abrading members withdrawn from the slots in which they rest. When the grinder is in use, how- 'ever, the abrading members are very securely held and are supported by the disks 2 and 3 against lateral displacement.
I have described in detail one specific form of grinder which is illustrated inthe drawings and have used specific descriptive words in so doing. It will be understood that I have done this merely in the interest of convenience and clarity and that the structure illustrated is not the only form of device in which my invention may be embodied and further that in speaking of it I have given'the various parts certain names with an identifying or descriptive and not with a defining or limiting purpose.
