DRIVING MECHANISM.

Specification of Letters Patent.

Patented Sept. 1, 1914.

Application filed March 3, 1918. Serial No. 751,862.

To all whom it may concern:

Be it known that we, DAVID H. TAYLOR and BE JAMIN E.-CONNELLY, citizens of the United States, residing at \Vheeling, in the county of Ohio and State of West Virginia, have invented certain new and useful 1m provements in Driving Mechanism, of which the following is a specification.

This invention relates to bufiing, polishing, and grinding machines, and has for its object the provision of a compact and simply arranged machine which may be readily controlled and guided by hand and which will operate economically and efficiently.

A,further object of the invention is to provide a machine of simple'form whereby a plurality of bufling wheels maybe actuated simultaneously.

The several objects of the invention are attained in such a mechanism as is illustrated in the accompanying drawings, and the invention consists in certain novel features which will be hereinafter first fully described and then more particularly pointed out in the appended claims.

The annexed drawing shows a plan view partly broken away and in section of an apparatus embodying our present invention.

In carrying out our invention, we employ a casing'l in which is housed an electric motor, the cable 2 by which the motor is connected to a source of electric energy-be ing extended through the rear end of the. casing. The casing.

is preferably constructed in two duplicate members secured together by screws or similar fastening devices 3 and provided with lateral offset-s or wings 4 having slots 5 extending longitudinally thereof to constitute handles whereby the casing may be grasped and directed over the surface to be treated. A driving shaft 6 extends through one end of the casing and'is connected within the casing directly to the motor which may be of any preferred or convenient type. The casing is provided with an extension 7 constituting a gear casing and within the said gear casing a beveled gear wheel, indicated at 8 in dotted lines, is fixed upon the driving shaft. Stub-shafts 9 and 10 are journaled in the bearings 11 provided therefor on the sides of the gear casing, as clearly shown. Beveled gear. wheels, indicated in dotted lines at 12,

' are fitted on the inner ends of the stubonce, are caused to rotate in opposite direc-' tions through the described gearing. The outer end of the driving shaft 6 is threaded, as shown at 14, and upon the said threaded I end of the shaft is engaged the hub 15 of a bufling wheel 16.

It will be readily seen from the foregoing description, taken in connection with the accompanying drawings, that we have provided a very simple and compactly arranged mechanism whereby a plurality of bufling wheels may be simultaneously operated so that a large surface may be quickly polished. The wheel 16 will operate in a plane at right angles ,to the wheels 13 which move in parallel planes but in opposite directions so that a very high polish may be imparted to the treated surface by successively moving the several buffing wheels over the same por tion of the surface. The maincasing or housing for the motor, being provided with a handle on each side, may be manipulated without fatiguing the operator and the power is applied directly from the motor to the bufling wheels. The bufiing wheel 16, it will be readily seen, is removable and a grinding wheel may be substituted therefor when so desired. The device may also be utilized as a drilling machine by substituting for the butting wheel 16 or the grinding wheel a drill chuck in which is held a drill bit, as will be readily understood.

The gear casing or extension has an open top which is normally covered by a hinged lid. The casing is filled with oil in which the bevel gears run so that thorough lubrication will be effected and the lid is constructed to fit tight against the casing to prevent loss of the lubricant.

What we claim is 1. The combination of a casing having lateral longitudinally extending ofisets on its sides provided with longitudinal slots, a gear casing carried by one end of said first mentioned casing, a motor mounted in the first-mentioned casing, a shaft extending from said motor through the gear casing, shafts journaled in the gear casing and prolateral longitudinally extending ofi'sets on jecting laterally therefrom, and 'gearing In testimony whereof We aflix our signawithin' said casing eonnecting said shafts tures in presence of two Witnesses.

2. The combination of a casing having DAVID H. TAYLOR. [11's.] its sides provided with longitudinal slots, a BENJAMIN CONNELLY' motor within the casing, a shaft extending Witnesses: from the motor and the casing, and gearing J ENNIE CONNELLY, actuated by the outer end of said shaft. LAURENCE GREEK.
