SURFACING-MACHINE.

Specification of Letters Patent.

Patented Jan. 24, 1911.

Application filed March 30, 1910. Serial No. 552,489.

To all whom it may concern: Be it known that I, GUY ALLOWAY, a citizen of the United States of America, and a resident of the city of Seattle, in the county of King and State of Washin ton, have invented certain new and useful mprovements in Surfacing-Machines, of which the following is a specification.

My invention relates to machines of the above type, havin more particular reference to machlnes for ressing floors, and has for its'.- rimary object the provision of a simplifie and improved construction wherein the operation of the dressin rolls is facilitated.

A further object resic es in the provision of a novel construction which can be readily reduced to a more compact form.

With the above and other objects in view, to be referred to as my description progresses, my invention resides in the features of construction, arrall ell'lents and combinations of parts hereinafter described and succinctl defined in my annexed claims.

Re erring to the accompanying drawings, wherein like numerals of reference indicate like parts throughout: Figure 1 is a side elevation, with parts shown in section, of a machine embodying the features ofmy invention. Fig. 2 is a top plan thereof. Fig. 3 is a fragmentary sectional view, on enlarged. scale, taken through the rotatable roll carrying head. Fig. 4 is a section taken on line 44 of" Fig. 3, with the dressing rolls removed. Fig. 5 is a section taken through one of the dressing rolls and its related pan. Fig. 6 is a fragmentary sectional view of the'rear end portion of the machine frame, and Fig. 7 is a detailed plan view of the upper guide for the vertically adjustable bear- In carrying out my invention I provide a rotatably supported head 1 which is conveniently provided with a pair of oppositely disposed axles 2 for the surfacing rolls 3,

the latter being provided with bevel gears 4 meshin with a relatively fixed similar gear 5, w ereby upon rotation thereof with ead 1 in a horizontal plane they will also be caused to turn about their own axes against the floor or other surface to be dressed as will be readily understood.

Head 1 is fixed on thelower end portion of a vertically disposed shaft 6 which is hollow and connected with a suitable dust receiver 7 through the medium of the coupling 8 and the conducting pipe 9, which latter has angularly disposed end portions on one of which con ling 8 is.slidably supported, thereby provi ing a convenient arran ement for efiecting ready disen genient o shaft 6, as will later be more fu y set forth.

Receiver 7, which is preferably formed of suitable fabric, can be supported in any desired manner, a preferred arrangement, however, consisting in making the same fast to the downturned discharge end portion of pipe 9, which latter may be suitably flared for an obvious purpose.

Head 1 is hollow and preferably divided into opposite chambers by a. vertical partition 1, each of which chambers has communication with a respective receiver or pan 10. These receivers or pans lO are disposed horizontally in front of respective dressing rolls 3 and form mouths for the dust collecting mechanism, suction being created therein, upon rapid rotation ofhead 1, to effect the conveyance of the dust-like material removed from the floor through action of rolls 3, as will be readily understood.

In supporting shaft 6 for rotation, I journal the same in a bearing 11, the same being in the form of an elongated sleeve and havin gear 5 fixed to itslower end.

iearing 11 is supported for vertical shding by guides 12 and 13, of a suitable supporting frame 14, and is confined between head 1 and a drive pulley 15, of shaft 6, whereby said shaft is connected therewith for simultaneous vertical adjustment.

Supporting frame 14 comprises a latform, mounted on suitable wheels 16, 16 the latter of which are preferably journaled in pivoted frames 16", and superstructure, as 14, preferably formed of hollowtubmg, as shown.

Reference numeral 17 indicates a suitable motor mounted on the platform of frame 14 and connected by a belt 18 with pulley 15.

Reference numeral 19 indicates an adjusting device for-shaft 6, the same being fulcrumed, as at 20, on the frame platform and connected with a grooved ring 21, loosely enwork-l4. (see Fig.6). This obviously places rolls 3 under a yielding pressureand enables them to abrade in a more even and accurate manner. In elevating rolls 3, lever 19 is swung 1n the reverse directlon to exert its lifting force through spring 22.

Guide 12 slidably receives bearing 11 and one section thereof is hinged to the other, as

12 and 13, as will be readily understood. While pipe 9 can be otherwise supported.

a convenient arrangement consists in mounting the same on an upright extension of I the frame superstructure 14".

A machine constructed as hereinbefore described can be operated in an efiieient man- -ner through the provision ofthe yielding like.

connection between the supporting frame and the vertical shaft of the surfacing rolls,

will collect the material removed by rolls from the surface being'operated on, and further, is capable of having its s'urfacing' rolls and adjacent related parts quickly positioned and removed from the frame.

Rolls 3 can be of any desired construction.

I prefer however, to construct the same with a removable facing 3 of" sand paper or the Having thus described my invention, what I claim as new, and desire to secure by Letters Patent' of the United States of Amer- 1ca,1s: i

1. A surfacing machine comprising a supporting frame, a head rotatably supported thereon, a roll rotatably su ported on said head, means for rotating said roll about its own axis by and during rotary movement of said head, and means for yieldingly pressing said head to its lowered position while permitting of relative vertical movement of said frame.

2. A surfacing machine comprising a supporting frame, a vertically disposed shaft supported on said frame for rotation and for vertical adjustment, a drive means on said frame for operating said shaft, a yielding connection between said shaft and frame tending to hold said shaft lowered while permitting'of relative vertical movement of said frame, a head on the lower end portion of said shaft, a roll rotatably supported on said head, and means for rotating said roll porting frame, a vertical shaft, a head on the lower end portion of said shaft, :1 horizontally disposed roll journaled on said I head, means for rotating said roll about its own axis during 1tS'Il10V8Il1eIlt,\V1tl1 said head, a bearing for said shaft supported for vertical adjustmenton said frame, said shaft being connected with said bearing for vertical adjustment therewith, means for adjusting said bearing, and yielding connecting means between said last means-and said bearing.

4. A surfacing machine comprising a supporting frame, a head provided with surface dressing means,a shaft carrying said head, means 011 said frame supporting said shaft for rotation and for vertical adjustment, said means including a vertically adjustable bearing, means on said frame for adjusting said bearing, and a yielding connecting means between said last means and said bearing.

5. A surfacing machine comprising a supporting frame, a bearing supported for vertical adjustment on said frame, means for adjustingsaid bearing vertically, yielding means interposed. between said first means and said bearing for holding said bearing lowered, a shaft journaled in said bearing and connected therewith for vertical adjustment, and surface dressing means carried by said shaft.

6. A surfacing machine comprising a supporting frame, a vertically disposed bearing, upper and lower guides supporting said bearing for vertical adjustment, adjusting means for said bearing, springs on said bearing on opposite sides of said adjusting means, a shaft journaled in said bearing and connected therewith for vertical adjustment, and surface dressing means carried by said shaft.

7 A surfacing machine comprising a 'sup porting frame, a vertically disposed bearing,

upper and lower guides removably holding said bearing for vertical adjustment, the lower of said guidescomprising outwardly projecting apertured lugs, guide lugs on said frame engaged in the apertures of said lower guide, a shaft journaled in said bearing and connected therewith for vertical adjustment, surface dressing means carried by said shaft, means for ad usting sald bear-mg vertically, and .a yielding connection be- I tween said bearing and said last means.

Signed at Seattle, Washington, this 22d day of March 1910.
