Description

I T. w. WATKINS, PORTABLE GRINDING AND POLISHING MACHINE- APPLICATlON FILED APR-5,1920.

mum Aug 9 19211;

mafisawo entree stares THOMAS w. warmers, or

KANSAS CITY. MISSOURI.

PORTABLE GRINDING AND POLISHING MACHINE.

' Application filed A ril 5,.

To all whom it may concern Be it known that I, THoMAs W. WATKINS, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a certain new and useful Improvement in Portable Grinding and Polishing Machines, of which the following, is a specification.

My invention relates to improvements in portable grinding and polishing, machines.

()ne of the objects of my invention is to provide a novel machine adapted for use in polishing floors, walls, tables and similar plane surfaces or for grinding purposes, and which is simple in construction, cheap to manufacture, easy to manipulate, .durable, not liable to get out of order, and which is efficient in operation.

My invention provides further novel means by which different abrading or polishing devices may be applied to the machine or removed therefrom.

The novelfeatures of my invention are hereinafter fully described and claimed.

In the accompanying drawing, which illustrates the preferred embodiment of my invention,

Figure 1 is a top view of my improved machine shown partly broken away.

Fig. 2 is a side elevation, partly broken away,,of the same.

-' Fig. 3 is a top view, partly broken away,

showing an abrading device and a polishing device mounted on the armature shaft.

Similar reference characters designate similar parts in the different views.

T he machine is provided a support comprising, preferably, a horizontal tubular body 1, a tubular arm 2 communicating interiorly with the body 1, and an arm 3 attached to the body 1 by a transverse bolt 4. The arm 3 is preferably provided with an inclined tubular socket 5 adapted to receive an inclined handle 6.

The arm 3 is provided with a detachable portion '7 attached to the main portion of the arm by removable bolts 8 and provided with a bearing 9 adapted to detachably support a horizontal rotary armature shaft 10 of an electric motor having a body or casing 11 attached to and carried by the tubular arm 2.

For carrying the machine upon a floor, table or other smooth surface, casters 12 may -Specification of Letters Patent.

Patent-ed Aug. 9., 192-1.

1920. Serial no. 371,414..

be respectively attached to the body 1 and arms 2 and 3.

Electrical conducting or connecting means comprising a cable or cord 13 containing the usual conducting wires is located in the body 1 and tubular arm 2 and connects the motor with suitable socket connection means 14 adapted to detachably receive in the usual manner an ordinary connecting plug 15, which may be connected in the usual manner to a lamp socket.

The armature shaft 10 is adapted to have removably secured to it, intermediate of the body 11 and the bearing 9, a device such as a polishing wheel 16, provided with a set screw 17, adapted to bear on the shaft 10. By removing the bolts 8, the portion 7 may be detached and the bearing 9 slipped off from the shaft 10, thereby permitting the .wheel 16 being slipped on or off the shaft 10. The outer end of the shaft 10 is adapted to have removably mounted upon it an adapter 18, in which may be mounted an abrading it will have a slight pressure on the floor or other surface which pressure can be decreased by pressing downwardly upon the upper end of the handle 6, which extends rearwardly beyond the vertical plane of the caster 12, which is mounted on the body 1. Or the pressure may be increased by pressing downwardly on the handle forwardly of the caster just referred to. By moving the machine about on the surface which is being polished, different parts thereof may be polished or ground as the case may be depending upon the nature of the tool mounted on the armature shaft.

if The caster 12 which is on the body 1 is capable of longitudinal adjustment thereon. In the operation of the machine, the casters on the arms 2 and 3, if desired, as well as the other caster may be removed.

V I do not limit my invention to the structure shown and described, as many modifica tions, within the scope of the appended claims, may be made without departing from the spirit of my invention.

What I claim is 1. In a grinding and polishing machine,

a tubular support having two arms, one of cal conducting means connected with said motor andv located in-said tubular arm and support.

2. In a grinding and polishing machine,

a support having casters adapted to rest on a floor, the support having a tubular body having two arms one of which is tubular and interiorly communicating with the body, the other arm having a detachable portion provided with a shaft bearing, the last named arm having a socket adapted to .receive a handle, a motor having a body carried by the tubular arm and provided with a horizontal armature shaft, said shaft bearing portion being arranged to detachably support said shaft, the shaft being arranged to have attached thereto intermediate of said body and said shaft bearing portion a polishing or abrading device, and

electrical connecting means connected with said motor and located in said tubular arm and tubular body, substantially as set forth.

3; In a grinding and polishing machine;

a support comprising a tubular body having two arms one of which is tubular and interiorly communicating with said body, said tubular body having means for connection with a socket member, the other arm having a shaft bearing and having a socket adapted to receive a handle, a motor having a body attached to and supported by said tubular arm and having a horizontal armature shaft mounted in said bearing and adapted to have secured to it an abrading or polishing device, and electrical connecting means located in said tubular body and said tubular arm and connecting said motor withsaid socket member connecting means, substantially as set forth.

4. Ina grinding and polishing machine, a support comprising a tubular body having means for connection with a socket member and provided with two arms, one of which is tubular and communicating interiorlywith said body, the other arm having a shaft bearing portion and an inclined socket, a handle mounted in said socket, a motor carried by the tubular arm and having an armature shaft arranged for detachable support in said shaft bearing andadapted to have secured thereto intermediate of. said bearin portion and the body of the motor a polis ing or abrading device, and electrical connecting means located in saidtubular body and said tubular arm and connecting the socket connecting means with said motor, substantially as set forth.

In testimony whereof I. have signed my name to this specification.

THOMAS w. WATKINS.
