ABRAIJING APPARATUS.

'lfatented they a, ionic Application filed December 31, 1909. Serial No. 5353M.

To all whom it may concern: c

it known that 'l, GlUSTAV A. Hassnn, a resident of Melfeesport, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in 'ltbrading Apparatus, of which the following is a specification. 1

My invention relates to a new and iniproved abrading apparatus and an object of the present invention is, to provide an apparatus of this class comprising a selfcontained, suspended or swinging structure desired distance from be suspended at any the ground or floor and capable of being moved at will either in a straight or a curved path. I

in the accompanying drawing, which illustrates an application of my invention, Figure 1, is ing apparatus; embodying my invention; Fig. 2, a part elcvational and a part longitudinal sectional view; Figs. 3 and 4; vertical sectional views respectively taken on line lll llll and line Il -IV of Fig. 2; and Fig. 5 a part eievatioinil, and a part sectional view, the section being taken on line VV of Fig. 2.

Referring to the drawing, 1 designates a frame preferably formed as an integral caststeelstructure comprisinga bed-plate 2, a vertical member 3 having a horizontaliled e 4-, a strengthening member 5, an outward l projecting horizontal shelf 6 having a bcaring nieinl'ier 7, and a strengthening webg extending from member 7 and under the shelf 3 to the vertical member or device adapted ,to

While' l have shown simple and convenient frame this frame may be differently constructed. Mounted on and movable with frame 1 is a motor, as illustrated and as preferred, an electric motor, although the motor may be of a different type. This motor 9 having its shaft 10 coupled with an end of a driven shaft 11 by means of a suitable coupling 12.

Shaft ll which is inclosed in a suitable casing 13, projects outwardly from the frame and has mounted on an end thereof between a collar i l and a nut 15 an abradinga wheel 16. "Wheel i6 is partially inclosed by a strong safety shield or hood l7 and se-- cured to said hood are operating handles 18. llood l? is preferably of the form shown and is adjustably secured to a flanged sleeve 19 by bolts 2% passgd lhrough the flanged portion of, the aieeve. and the slots ill a perspective view of an abrad formed in the back of the'hood, In Fig. 5,

the dotted lines indicate how the hand may be shifted when so desired. 1

The abrading apparatus is designed to he siispended from example, a chain 22, at any desired'height. The supporting means and the apparatus are connected by a universal joint connec tion comprising in the construction shown, a saddle member consisting of a base 23" cured. to the shelf 6 by bolts 24, and two uprights 25. Extending into the saddle and pivotally secured to the uprights thereof by a pin or shaft 26 is a. connecting member 27. Member 27 in turn is end of an eye-bolt 28 by means of a collar 29. This construction provides a simple universal joint or coupling permitting the apparatus to be readily moved at Will in any direction:

The parts of the hpparatus are so proportioned thathenthe apparatus is suspended, as shown, it is a substantially balanced struc-. 'ture and may be easily moved to bring the,

position,

What I claim is:

1. An 'abrad'ng apparatus comprising a suspended frame, means for supporting the k driven shaft eoiipled with the motor shaft, an abradin'g wheel mounted on the driven shaft, and a universiil'joint connection between the frame and the supporting means.

2. A suspended ab prising aframe, a motor mounted on the frame, on ineased' driven shaft coupled with the motor shaft and projecting from the frame; an abrading wheel carried on the paratus, a universal joint connection betweenthe frame and the supporting means, and a hood provided with an operating handle. 3. A suspended and substantially bulanced abradiug uppuralus comprising frame, a motor mounted on the frame, a

driven shaft coupled with the niothr shaft, an abrading wheel carried on the end of the driven shaft, means for supporting the apparatus, arid a between the frame and 'the supporting means comprising an upright n'ieinber, a depending member pivotally connected with ing member and supporting means.

a suitable support as, for

secured to the lower 79 abrading' wheel intothe desired operative so frame, a motor mounted on the frame, e385" ading apparatus coindriven shaft, means for supporting the up universal joint connection the upright, and a rod between the depcud 1 0 prislng a led with the motor shaft and projectingrom the frame, an abrading wheel mounted on an end of the shaft, an adjustable hood for the abrading wheel provided with an operating handle, means for supporting the apparatus and a universal joint connection between the frame and the supporting 1 means.

In testimony whereof I afiix my signature in presence of two witnesses.
