POLISHING-MACHINE Specification of Letters Patent.

Patented Feb. 4', 1908.

Application filed October 1,1907. Serial No. 396.302;

.useful Polishing-Machine; and I do hereby 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 use the same This invention pertains to a new and useful surfacing machine; and the invention, in its broadest aspect, resides particularly in the new and especially constructed means for raising and lowering the abrasive or buding disks, or in other words the polishing mechanism, in combination with the general construction of the apparatus.

The invention cites .as a further object to provide a simple, efficient form of frame for supporting the motive power, the polishing mechanism and the means for raising and lowering the said, polishing mechanism;

A further object of the invention dwells in the special construction of the frame, which consists of one solid casting horizontally disposed," as clearly illustrated; a still further object of thejinvention resides in the disposition of the frame, relative to the motive power, and the polishing mechanism, the means for transmitting motion to the said olishin mechanism and to the raisin and lowering mechanism.

This invention comprises l 'urther objects and combinations of elements which will be hereinafter more fully described, shown in the accompanying drawings, and the novel features thereof will be pointed out by the appended claims.

The features and elements and the arrangement thereof for accomplishing the objects of the invention may be changed and varied, that is to say, in a practical application of the apparatus, with an understanding that the changes and variations accruing from said application are limited to the scope ofthe appended claims.

. To obtain a full and correct understanding of features, elements and advantages, reference is to be had to the hereinafter set forth in connection therewith, wherein Fi ure 1 is a side elevation of the surfac- D u I a mg machine, showing the raising and lowering mechanism, for the polishing mechanism in side elevation. Fig. 2 is a sectional view on line 22 of Fig. 1.

spective view of the raising and lowering mechanisms for the polishing mechanism. Fig. 4 is a sectional view through the buffer wheel, showing the space in which oil is 0on 'tained, preferably linseed oil. Fig. 5 is a side elevation illustrating a modification, in which the motive power is vertically disposed, and the frame is of a triangular form. Fig. 6 is a sectional view on line 6 6 of Fig. 5. Fig. 7 is a detail erspective view of the means for raising and lowering the polishing mechanism.

In regard to the accompanying drawings, wherein similar reference characters indicate corresponding parts in the several illustrations, by figures, 1 designates the frame of the apparatus which is horizontally disposed, and is angular in contour, and is provided with bearings 2 at the front and rear thereof in which shafts 3 and 4 are journaled, as clearly shown. The shaft 3 has provided upon its lower end an abrasive or buffing disk 5, upon the lower face of which felt or sandpaper is fixed by means of a clamping ring 7, which has threadedconnections with the said disk; this disk is provided with an inner chamber in. which oil, preferably linseed oil, is contained, as clearly shown. The lower ace of the said disk is perforated, so as to allow the oil to percolate therethrough, so

understood from the drawings. The shaft 3 is also provided with a pulley 8, around which the pulley 10, fixed to the lower end of the shaft 2, as clearly shown. Fixed to the upper end-of the shaft 2 is a beveled gear 11, which is in mesh with the beveled gear 12 mounted upon the driving shaft 13 of the motor 14, which is fixed to the upper face of the said frame, and is supplied with current in any suitable manner. V

The frame 1 is provided with a pair of caster wheels 15, which are fixed near the rear end thereof. as clearly shown. The front 7 portion of ..16'fi8.111i5 provided with a bear- {ing 16, in which the shaft 17 of a single caster wheel 18 is journaled, as clearly shown in Fig.

l from the said frame is a pair of members 19 i between the upper ends of which a suitable l handle 20 is fixed, for the purpose of steering as to cooperate with the felt as' will be clearly the belt 9 travels, which belt also travels over Fig. 3 is a detail per- 1. Projecting rearwardly and upwardly polishing mechanism.

the apparatus over the surface to be polished,

with a pair of bearings 23 in which the lever.

24 is pivotally mounted, as clearlyshown.

This lever is forked at .15 lower end, as showrr' at 25, and the arms 26 thereof are slotted, as at 27, to receive the pins 28, projectinglaterally fl'ulll the sleeve 29, carried by the upper end of the said shaft 3. This sleeve is prevented from downward movement upon the shaft 3 by means of a shoulder 30, and is pre vented from upward movement by means of the washer 31 and the nut 32, as will be clearly depicted from Fig. 1 of the drawings.

The upper and rearward end of the lever 24 is provided with a portion 33 which is angularly disposed to the body portion of the said lever, and is for the purpose of being engaged by the Ushaped portion 3% of the sliding meml r 3'' for the purpose of raising and lowering the said shaft 3, which would, as

will be clearly manifest, carry therewith the This slide is movable upon the bar 21 a d is provided with a rearwardly p1'oje.. i11g .nember 36, which is provided with a downwardly disposed handle 37, as clearly shown; this member 36 having its handle 37 is for the purpose of operating the said slide upon the bar, which would cause the said lever 24 to oscillate, so as to raise' and lower the polishing mechanism. v

In Fig. 5 the frame is triangular in top view and the motor is vertically disposed so as to provide its driving shaft with the pulley 10 with which the belt 9 engages. The means for raising and lowering the polishing mechanism is identical with that shown in Fig. 1, with the exception that the bar 21 is fixed between the bearing 2 and a clamp 38 carried by the said motor, as will be clearly manifest.

From the foregoing, the essential features, elements and the operation of the device, together with the simplicity thereof, will be clearly apparent.

Having thus fully described the invention,

what 1s claimed as new and useful by the protection of Letters Patent, is

1 In a surfacing machine, a frame, a

motor having a driving shaft mounted there-' on, said frame having at one end a olishing mechanism having a shaft while t e other end is providedwith gear mechanism for transmitting power to the polishing mechanism, and a belt forming the medium for transmitting the power from the gear mechanism to the polishing mechanism,means for raising and lowering the olishing mechanism comprising. a pivotaly-mounted'lever having an angularly disposed rear ortion and pivotally mounted at its front en to the shaft of the polishing mechanism, a bar having a movably mounted slide to engage the angularly disposed rear portion so as to raise and lower said polishmg mechanism.

I .2. In a surfac'ing'n'iachine, a frame, a polishing mechanism at one end thereof having 'a shaft, a motor fixed to the frame, gear and belt mechanisms for transmitting power from theopposite end of the franie to the olishing mechanism, meansfor raising and J owering said polishing mechanism compris ing a lever having an angularly disposed portion and pivoted tothe shaft of the polishing mechanism, a bar, a slide movably mounted thereon and adapted to engagesaid angulary sposed portion for raising and lowerin tl rearwardfr.

3. In a surfacing machine, a polishing mechanism, a motor having gear and belt mechanisms for operating. the polishing mechanism, means disposed and so porte upon the upper portionof the motor or raising and-lowering the polishing mechanism comprising a lever having angularly disposed means, an angularlydis osed bar, a member slidable thereon adapts to engage said angularly disposed means for raising and lowering 95 the polishing mechanism.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
