" OFFICE WILLIs J. BEBNETT, -or KANSAS CITY, MIssoUaI,'AssIeNon To WILLIAM is. THAYER,
' or KANSAS cIrY, ms soU1tI.
rI'IcTIoNAL coUILING.
T all who/lt it may concern Be it known that I, WILLIS J. BERNETI, a
citizen of the United States, residing atv Kansas City, in thecounty of Jackson and State of Missouri, have invented certain new and useful Improvements in Frictional Couplings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and or other metal trimmmgson or in buildings.
In accomplishing this object I have provided the improved details of structure hereinafter described and pointed out in the claims, reference being had to the accompanying drawings, wherein:
Figure I is a perspective view of a portable polisher constructed according to my invention, the motor case being in section. Fig. II is an enlarged detail view of the tool head and driving mechanism showing parts in section and a tooLabout to be seated vin the head'. Fig. III"`is a detail perspective of the tool'head socket. l
Referring more? in detail to the parts':`-v 1 designates a -notorof any ordinary type,
but preferably electrical, :fnd 2 a case which incloses the", motor and has a handle 3 by` j is frictionally connected therewith through a washer C251 which -is fixed to the shaft end which it may be carried.`
-Supported on a shelf 41 in the upper portionof the case 2 is a-plug socket 5 for conthroug anA ordinary plug and cord (not shown), the socket being adapted for-exposure through an opening 6 in the case, and for protection (when the polisher is jiot in use) by a cover'7 which is adapted to close the opening 6. v
The motorI is controlled by a switch 8 which is connected with the motor and plug socket in the ordinary manner.
The motor shaft 9 prjects through the end of the case and has a flexible shaft 10 connected'therewith by a coupling 11.. The free end of the flexible .shaft extends freely through avbore 12 inthe base 13 of a tool head 14, comprising the apertured base and Spe'cifeation of- Letters Patent.
which has a shank 22 themotor with a source of energy- Patented May 1I, 1915.
Application filed January 6, 1913. Serial No. 740,441.
a barrel 15 which latter is4 threaded onto v the base and has a closed outerend 16. l Located in the bottom ofthe head 14 is a cup 17, having a. ball race in4 its lower face within which the balls I18 are adapted. .to
bear to provide an antifriction bearing vof the cup on the baseof the head, and having a flange 19 extending to the inner faceof the. barrel 15.
Revolubly mounted in the barreh 15 is a socket'member 20, the outer end of which projects through an aperture 21 in the outer end of the barrel and has a flange located within the barrel and projected to the inner face' thereof, 'andflthe inner end of o, ejected into the c up K 17, .both theiiange 20 and shankw22 having antifriction members 23 interposed between same and the barrel end 4.16 and cup bottom' respectively tofacilitate the revolution of thesocket member. The socket member is adapted to' receive the shank 2% of a tool 25, such as a b'rush' or burnisher, and has T Ashaped grooves 26 thereinadapted for receiving the studs 27 on the sides `of the tool shank, lso thatiwhenthe shank is projected `into the socket and the latterv is turned (as will presently "be described),the` studs will lock in the head bf the groove and' hold the` .tool' in place.
j The shaft 10 projects through an aperture w28 in the base of the cup 17 and is fixed thereto by a pin 29 so thatkthe cup is revolvedwith the shaft, and extends through `anc aperture 30 the .socket shank 22. The 'end of the shaft is-revolublein the shank aperture but by .a screw and `overlies the base of the socket member, the frictional connection being maintained by a spring 33 which sur rounds the socket and 'cup members and -rbears against thefcollar and cup'ilanges 20v and 19 respectively. Thepring 33 is suiii- .ciently stiff to maintaindriving connection between the shaft and socket member under ordinary conditions but allows 'the washer to slip on the" base of the socketV member .should more than Vtl'n': o1dinary load be placed on the tool, to obviate overloading .the motor.
f When the parts are constructed 'and assembled as described, should it be'desired to `use the device forany purpose for which it J spot and the motor connected with a circuit line by running the cord to a socket on the line. Circuit is then switched into the motor and the tool operated by means of the iexible shaft, the spring holding the fric- -tional connection between the shaft and the socket within which the tool shank is carried. Should too great a load be placed on the tool, the load will overcome the tension of the spring and allow the washer to slip on the socket base, thereby obviating overloading of the motor. A f
It is an easy matter to transfer the motor from place to place so that metal ware in different parts of or around a building, within the reach of the connecting wires,
may be polished with tools .operated by the.
motor, and it is also an easy matter toreplace one tool with another when the use of the device is to be varied. Having thus described my invention, what I claim is new therein, and desire to secure by Letters-Patent, is:
1. In a frictional coupling, tion with a drive shaft, of a cup fixed to said shaft, a socket member revolubly mounted on said shaft and withinsaid cup, a screw the combinaand washer for holding said socket member to said shaft, a spring for yieldingly tensioning said socket member against said screw and Washer and adapted for frictionally connecting said cup and socket member, and anti-friction mountings for saidsocket and cup members.
2. In a frictional coupling, the combination with a drive shaft, ofa cupifixed to said shaft, a socket member revolubly mounted on said shaft and within said cup, means for holding said socket member toy said shaft against longitudinal movement in 'one direction, a spring for yieldingly tensioning said socket member toward said holding means and adapted for frictionally connecting said cup and socket member, and .an anti-friction bearing for taking up the thrust of said socket member in the opposite direction.
In testimony whereof I ailix my signature in presence of two witnesses.
