EYE AND FACE SHIELD FOR EMERY AND GRINDING WHEEL OPERATORS.

Application filed December 14, 1923. Serial No. 680,622.

1 '0 all rv/1.0122, it may concern:

lle it known that I, lliiorrixs J. Kininmnni, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful In'iprovements in Eye and Face ,more emery or grinding wheels, and ad justable so that a trai'isparent member thereof will be interposed between an emery or grinding wheel and the face of an operator using said wheel for grinding or polishing purposes.

Among the objects of my invention is to obtain a'device of the kind. recited which is easily mounted on the base of floor grinders of different sizes, and whether the journal bearing of the emery wheel or grinder is secured to said baseby one or two bolts on each side thereof; and in case said two bolts are used to secure said journal bearing to said base, said device may be secured in place regardless, within a considerable limit, of the variation in distance between said bolts in the different makes and sizes of floor grinders and emery wheels. An additional object is to obtain a device of the kind recited which is easily mounted in place adjacent to an emery or other abrading wheel, or wheels, upon a wall or post, and which, when mounted, can be readily positioned to suit the needs of the operator, so as to protect his eyes and face from sparks or other material thrown off by the contact of the article which is being ground or polished by its being forced into contact with the revolving emery wheel or other abrading surface; said device being provided with a transparent member which is positioned so as not to interfere with a view of the material being operated on. An additional object is to obtain a device which may be mounted at the rear of the emery or other abrading wheel, and the transparent member thereof may be adjusted to'a desired position and angle in front of said emery or other abrading wheel. An additional object is to obtain a device of the kind recited which can be adjusted in a desired positlon by the operator without recourse to bolts or nuts to maintain the transparent member thereof in said adjusted position. An additional object is to obtain a device of the kind recited whiehis econon'iically made, durable, and not liable to breaker to get out of order.

Floor emery wheels or grinders to which this apparatus is specially designed to be attached are made by several manufacturers and in a number of different sizes, in all, however, so far as I am advised, there is a standard having a table or base at the upper end thereof and a journal bearinghaving a base resting on and secured to said table by bolts. floor emery wheels or grinders there is a bolt in the rear of the base of the journal hear ing, extending through said base and into said table, and an additional bolt extending through said base and into said table in front of said standard; while in the larger sizes of said floor emery wheelsor grinders, there are a plurality of bolts both in the rear and in front of the standard of the journalbearing extending through the base thereof and into the table of the floor stand. Where a plurality of bolts in front and rear of the standard thereof are used to attach the journal bearing to a table the distance between said bolts varies with the different makes, there being no standard with reference thereto. I have therefore designed a base forming an element of my invention which can be secured to the base of the journal bearing of all makes of floor emery wheels or grinders that I am at present advised of, by simply removing one or two of the bolts attaching the base of the journal bearing to the table of the floor stand, placing said base of my device on the base of the journal bearing and replacing the bolts or bolt previously removed therefrom, or substituting a bolt ofthe same size but of slightly greater length, in place of said removed bolts; and at the same time I obtain a base which is attachable to a vertical wall or post by one or two bolts, as preferred. I

In the drawing referred to Fig. 1 is a side elevation of the upper end of a floor stand, a journal bearing secured thereto, an emery or grinding wheel the shaft whereof is rotatably mounted in said journal bearing, and an eye and face shield em- In the smaller sizes of some of said bodying this invention mounted thereon by a single bolt extending through the base of the device, the base of said journal bearing and into the table of the floor stand.

Fig. 2 is a top plan view of the base of the device attached to the base of the journal illustrated in Fig. 1, by a plurality of bolts,

showing a portion of one end of said journal base in top plan view and a portion of a vertical m'ember forming an element" o'fthe device in horizontal section.

Fig. 3 is a side elevation of the base'of" the device, attached to the base of a journal bearing, as in Fig. 2 and showing in vertical section, a portion of said-base of the journal bearing, and in .side elevation a short section of a vertical member forming an element of the device.

Fig. at is a top plan view of the base of the device and ofa portion ofthe base of a journal bearin anda horizontal sectionof a vertical member of the device; said parts beingassenibled in the manner illustrated in 1.

Fig. 5 is a side elevation ofthe several parts which are illustrated in Fig. 1, with the base of the device turned 180 from the position thereof which is illustrated in Fig.1

Fig. 6 is aside elevation of a section ot-a wall, or post, and of the base otthe device attached thereto by a plurality oiibolts, and

nate a given part indicates said upper part throughout the several figures of the drawing wherever'the same appears.

1, Fig. 1, represents the upper endofthe standard of a floor stand, 2 represents a table at the upper end of. standard 1. 3

represents the base of a journal bearing, 4; the standard of said journal bearing and 5, 6,bo:lts extending through said base 3, with the screw threadson said bolt fittingfinto corresponding screw threads in an aperture in-table 2, thereby attachingsaid journal bearing to said table. 7, 8, respectively represent the members of a two part base fornr ing an element ot'the invention. 9, 9, represent a reverse bend in members 7 and'S. Where the base members 7, 8, are attached to a table by a single bolt, as 6, Figs. 1, t

and 5, said members are arranged one over the other, as is well illustrated in Figs. 1 and 5, and the bolt 6 is extended-through apertures in both of said members, and into the table 3 and into a screw threaded aperture in table 2. III-grouping the members 7 and 8 as above described it is immaterial whether said members are attached to table or base 3 and table 2 in such manner that the unattached ends thereof are in planes lower than the planes of the attached ends,

as is illustrated in Fig. 1, or whether said unattached ends are in planes which are above or higher than the planes of the attached ends, as is illustrated in Fig. WVhere the two part base formed by 1nembers 7 and 8 are attached to base 3 by two bolts, 6, (3', as is illustrated in Figs, 2 and 3, one of the members 7 and 8 is turned, say from the position in which it is illustrated in Fig. 5, so that the side thereof opposite to the side in contact with said table, 3, in said Fig. is in contact with said table, the other of said members (8), being in the same relative position to table 3 as in said Fig. 5;b'u't in contact therewith. 1O represents a vertical standard of the device, and preferably consists ot'a pipe or tubescr'ew threaded at both ends thereof, as at 11, Fig.

1, the lower one of said ends fitting into coire'sp'on'c'ling screw threads in an aperture in said members 7 and 8, thereby firmly securing said standard in said base. 12'represents a ti 'ible member well known in the art of electric lighting, and comprising a coil of resilient wire within a coilof wire of tensile material, which is not resilient, said outer coil being made of wire which is substantially triangular'in cross section, and wound closely to the coil of resilient wire. The construction of this flexible member forms no part of my invention, and so is not illustrated in detail. represents a head which is liri'nly secured to one end of the flexible me'1'nber12, and is provided with in"- ternal screw threads fitting tightly on to screw threads 11 on the upper end o'f sta'ndar'd 15 represents what is known in the art ofpipin'g as a' drop elbow, which is provided with lugs or ears 16, 16; said lugs haji' in'g apertu s through which bolts, 17', 17, are extended to securesai'd drop elbow to any desired base. 8, 18, rcspecti ely represent nuts on bolts 17, 1?. It will be 01 served on comparison otFigs. 1 and 7, that the drop elbow 15 is turned in Fig. 7 from the position in which it is illustrated in Fig.

1,-so'that'one ot said lugs 16, and bolts 17 are shown in F 1, the other'ones thereof are shown in F 1g. '7. One end of the flexible member 12 15 secured. in one (19) end of drop elbow 15, in Fig. 1, and into the other (20) end thereof in F T. 21, Fig. 1, and 22', Fig. 7 represents a ii'ame and a inodili cation of said frame. Frames 21, 22, enclose a transparent plate 23, the upper end of llt) lugs or ears 16, 16, are applied to one side of the frame and secured thereto by bolts 17, 17 and nuts 18, 18, as hereinbefore recited; or by other suitable means, as rivets. Whichever form of frame is adopted, the plate 23, of transparent material is not necessarily changed in size, or shape.

here it is desired. to attach the members 7, 8, of the two part base of my device to a vertical wall or post, said members may well be brought into the same relative position as is illustrated in Figs. 2 and 3, and attached to said wall or post by bolts (5, (3, as is illustrated in Fig. .(5. The slight variation of said members from a vertical plane not affecting the etlieiency of said members as a base. 24, Fig. (3, represents a street elbow, which is interposed between the lower end of standard 10, and said members 7 8, when said members are in substantially vertical planes; one end of said street elbow being screw threaded in the ordinary way, and lit- I ting into corresponding screw threads pro- 'vided therefor in apertures in said members 7 and 8. By interposing the street elbow 24-, the standard is mounted and maintained in a substantially vertical position, as in Figs. 1, 3 and 6. It is evident that where the members 7, 8, are attached to a vertical wall or post by a single bolt, said members may be placed in the same relative position as they are illustrated in Fig. 5, and the bolt extended through apertures in said members and into the vertical wall or post in the same manner and direction as bolt 6' in said Fig. 5, extends through apertures therein and into table 3. lVhen so secured to a vertical wall or post both ends of members 7, S, will be in planes parallel to the plane of the wall or post, and the street elbow 2% will be attached to said members 7, 8, in the same manner as is illustrated in Fig. 6. It will be noted that by my constructing a two part base of members 7, 8, in the manner hereinbefore described, said base is attachable either to a horizontal table or to a vertical wall or post by one or two bolts and that when two bolts are used the distance from one thereof to the other may vary by a considerable amount with a corresponding difference in the angular relation of said members 7, 8.

I find, in practice, that where one end of the flexible member 12 is secured to a vertical member, as standard 10, and said flexible member is bowed or curved so that the other end thereof is in an inclined plane, say substantially as illustrated in Fig. 1, said flexible member will retain said position, the weight of the several. parts on the inclined end thereof not being sutlicient to change the position of said flexible member 12 throughout the body part thereof, or at said inclined end; and that the frame 21, (or 22), will not be moved from an adjusted posi- ,members of the device being simple, and

having been. hereinbefore recited, no further explanation thereof appears desirable or necessary.
