Application filed March 26, 11918, Seria1.No..224,748. renewed February egf-iezo. Serial no; 355397;
To all/whom itma z) concern: I Be it known that I, ALEX A. CLARKE, a
citizen of the United States, residing at -Dal-- las, in the county; of Dallas and State of Texas, have invented certain new and useful Improvements Surface-Treating Ma-. chines, of which the following is a specifica tion. 7 w
This invention relates to surface-treating machines. o The idea involved inthisinvention .is to provide a surface-treating member in an annular form andto dispose within the samea I complete driv ng and operating unit, where- I by the memberiis revolvedg andtsto associate with said member and unit a supportwhereby the surface-treating member, isycarried and may be appliedtothe workxunder full In carrying out the invention an annular surface-treating or. abradingqmember s mounted on aMself-contained motor/unit which in turn is mounted in a supporting frame. The motor unit is electrically driven and" this obviates gears and othenpower transmitting ,devices and provides; for 4 simplicity, as well as adirect,applicationiofthe power tov the abrading member. The .motor unit is journaled -in'thesupportingirame, 30
and the, said framehasoneach side oifthe abrading :membera pair of-legs or stands ards, .one of which is adjustable,j:whereby the support may be adjustedtoward and from the workand thefdepth of the-cut ,or
pressure of the surface-treating member controlled at; will. 1 E
In a a more p c c embodiment. o t e invention avrectangular ;su pport1ng;frame 18 o provided and carries at each corner a leg,
the leg a one e d being a ju t leelectric motor is mounted in the frame" and is of that type 7 in which i the, :fields revolve and are carried in a cylindrical housing.
On; the periphery ofthis housing an annullar surface-treating member is confined; The feet'orouter extremit esof the support-:
ing legs are brought into contact with the surface to be treated andby the adjustment r A provided the projection of the surface-treating member beyond the plane of the extremities o'lsaidlegs is controlled, and said-surface-treating member may be adjusted to the work to a minute degree v invention is illustrated, and wherein -v I suitablehandlesby workman may holdand control themachineQ: I
1 a The invention will-be more readily under stood from a reading of the followings'peciticatlon and byreference to the accompanyngdrawing'; in which anexample of the F gure 1 is ,ajsid'e elevation of amachine constructed in accordancewith' this invention, a portion; being illustrated in section,
Fig 2 is an end elevation of the same," and @F1gt3 1s a plan view.;' 7
asimilar pairotstandards3 are provided at theoppositeendof said plate. Oneach side the standard 2; is; connected with the standard?) by asidebar. isubstalitially par allel thefplate The standards Sare me t by m sba 5: 1 =.the's.a Plane with the bars ft. The parts l to-5 inclusive iornia supporting 'orgcarrying frame-the particular vtormation of which maybe va r1ed.'. A stat onary armaturefi has-vits ends fastened in the sidebars :andextends-bee V.
tween. same centrally of the frame; ,-A motor housing 7 surrounds the j armature and carriesfltlie iusual I fields (not shown), whereby it isrevol-ved. v r commutator ';8;', is carried by the hous ng and brush-terminals 9 mounted Oilihfl pl ted have engagement with said it o ator. The motor unit is not illustrated indetail as it is of a typefohow in commen use and vwell known in the art of elec tricity, Wires -10 lead from the terminals 9 to I a switch socket 11, adapted to receive an attachment plug 12 wherebyelectric current may bee supplied to the motor and controlled as; desired; I
' I f housing? ery, andrcarriesj an vannular} abradingmember 1'3 fitting snugly thereon and-formed of suit 5- able; material as sand :paper, emery cloth or the like, It willlbe-seen that the surfacetreatmg member is Icarried by a revolving motor un t and gears and, similar driving elements; are eliminatedg Thi provides ;a,
very lsinple construction and affords not only a d rect application .ofithepower to the surface-treating memberbut a high speed of reyo ution which is 1 quite desirable e in I this a io rm hmesworked on, the member 13 will engage said surface as indicated in Figs. 1 and 2. Legs 16 are threaded through the standards 3 and carry feet 17 on their outer extremities. It will bereadily seen that by adjusting the legs 16 the relation between the member 13 and the surface to be worked is controlled. Said legs 16 maybe projected to the point where the said member 13 just engages the working surface, orthey may be retracted so that the member 13 will bury itself and cut deeply into thesurface being treated. It
' Y evenly.
is obvious that the legs 16 should be adjusted in unison and should have their feet 17 in registration sothatthemember 13' will at tack the working surface uniformly and It is apparent that various means for adjusting the legs 16 might be provided. In the drawings I have shown a handle member comprisinga tubular hand-grip 18 extending transversely of the plate on the opposite end fromthe standards 3 and rotatably confined in'brac-kets 19. The grip 18 has portions projecting beyond the brackets and carrying beveled gears 20 which mesh with'beveled pinions 21'rotatably confined in bearing boxes 22 secured to the brackets 19. The legs 16 project-up through the pinion's and are threaded therein so that when said pinions are" revolved said legs are moved longitudinally. The legs 16 are suitably held against rotation. 'At' the opposite end of the plate a handle member 23, having a transverse hand-grip 24 is mounted.
. In using'the machine the operator grasps the hand-grips 18. and 24:, and after having manipulated the switch 11 to'start the motor, heplaces the feet 15 and 17 against the surface to be treated and'by turning the grip 18 the'legs 16 are projected or retracted from the frame through the instrumentality of the beveled gears; thusathe abrading action of the member'13 on the surface may be regulated to a'nic'ety. If the abrading member'13 is not cutting deep enough or exerting sufficient pressure on the work the workman has only to rotate the part 18-to withdraw the legs 16, whereby the member '13 islet into the surface, but if'themember 13 is cutting too deep or acting'too severely on the surface thepart'18 is revolved in the opposite direction whereby theilegs 16 are projected'and the member 13 withdrawn. The pitch of the threads on the legs 16 and the ratio of the gears and pinions are such that only a slight rotation of the part 18 is necessary to obtain an adjustment of the abrading member 13, but not so rapid as to prevent a very' minute adjustment. The operator moves the machine over the surface being treated and the abrading member 13 removes the material from the surface or of the surface according to its adjust- 'ment. It is obvious that the member 13 might be a grinding member or a polishing member, butin the latter case considerable skill would be necessary on the-part of the workman in passing the machine over the surface in order 'to get asmooth and even job,therefore the machine is more particularly designed for abrading and grinding rather than polishing." V 7 It will be seen that the machine may be used to work on surfaces in all positions to which access may be had. In treating the surfaces of a body the top, sides, ends and bottom, both inside and outside, may be efliciently worked on, provided there is room for the machine. The machine is at all times under the direct control of the workman and owingto thev high speed. of revolution of the abrading member the workmay be expeditiously performed.
The foregoing description andillustration clearly express the invention, but it is to be understood that said illustration is merely an 'exemplification and the invention may be the frame on each side of the housing for positioning the surface treating member with relation to the surface of the work,
saidelements being constructed to effect an advancement or retraction of the surface treating member with relation to the surface of the work.
2. In a surface-treating machine, the combination of a supporting frame, of an electric motor mounted in the frame and including a revolving housing, an annular surface-treating member mounted on the housing of the motor, handles on the frame for holding the same, a pair of fixed legs at one end of the frame, a pair of adjustable legs at the other end of the frame, said surface-treating member being disposed intermediate the ends of the frame and between the legs thereat. T
' 3. In a surface-treating machine, a supporting frame, an electric motor mounted the surface-treating machine, a pair of adjustable legs projecting from the frame on L the opposite side of the surface-treating member, a handle fixed atone end of the frame, and a combined handle and adjusting device mounted at the other end of the frame and having connections for advancing or retracting the said ad'ustable legs.
