Toallwbomttmayconcem:
Be it known that I, FRED R. ALLEN, a citizen of the United States, residing at the city of Providence, in the county of Providence and State of Rhode Island, have invented certain newand useful Improvementsv be in SurfacingMachines,
of which the following is a specification,
reference being had nying drawing.
This invention re ates to floor surfacing machines, and has for its object to provide a portable machine constructed with a sin le upright spindle through whifih a plurality 0 power driven surfacing re a double motion which includes their bein rotated on their own axes and also revolve about a common center.
A further object of this invention is to provide means whereby the rolls may be rotated on their own axes but prevented from rotating about the common center when in Operation. I
It is found in practice that a machine having surfacing rolls which move straight ahead, or whose axes are 'fixed atright angles to the direction of travel, are best out, that is, taking off the high places, suc as the joints, butts, etc., of the floor. Such rolls are also adapted to more readily follow the depressions and unevennesses in the floor and clean the same, while a machine having rolls which also revolve about a common center is the best for such purposes asjfinishingfloors of bowling alleys andthe like, where a perfeetly plane or level surface is required. The first mentioned arrangement of rolls, which removes'but a small portion of the surface and cleans the same, makin the whole look bright and new, is desired in the majority of cases, as such a finish, on account of the saving in time, is much less expensive.
In carrying out my invention I provide a machine which is adapted to be operated in either of-the manners above described, and maybe changed from the double motion machine to the single motion machine by simng the .two sets of mechanismll and removing one set. of the surfacing re s.
v A further advantage of my oved ma.- chine is that all of the rolls may ge removed Specification of Letters l'atcnt. Application filed October a, not. sum 110. 456,874.

from their respective spindles and 'olishing or finishing blocks may be attachemf in place thereof. By this construction it will be seen that with one machine a variety of work may be accomplished whereby any floor ma finished in exactly the manner requ' either with a tained by the ouble motion head, or a surface may be cleaned and mademately level with the strai and either may be finish.
approxit ahead rollers, and polished by the application of the blocks, all by the operation of a single machine.
With these. and other objects in View, the of certain novel features as will be more fully deand particularly pointed out in the appended claims.
of construction,
In the accompanying drawings: Figure.

Fig. 4- is a section on line 4.4 of Fig. .1 Fig. 5- is anenlarged view illustrating the carriage driving and reversing mechanism. Fig. 6- is an enlarged re'ar View showing the locking pin for holding the steering handle in its up position.

Fig. 9- is a per ective view of a rectangular block ada t carried by the head and take the p ace of the surfacing rolls. v
Referring to the drawings, 1 designates the. frame or body portion of the machine on which the motor2 is mounted. The forward end of this body portion is provided with any upturned vertical plate 3 ribbed at 4-4 on either edge, in' which plate the head is pivotally mounted. This body portion or carriage is referably mounted on three wheels the two orward or driving wheels 6--6, which are mounted in brackets -7-7 on shaft 8, are not allowed to pivot or swing while the rear wheel 9 is mounted on shait 11, see Fig. 8, to pivot or swing on the trun- 10' in the yoke perfect sirface, which is b.-

not shown, thus forming a grease tight box in which said worm and gear are adapted to work. The lower bearing 31 is provided with a bushing 34, the lower end of which bushing is enlarged at 35 and is adapted to receive one end of each of the horizontal shafts 36 and rigidly sup ort the same, said shafts being preferably our in number. Rolls 37-37 coveredwith surfacing material are mounted on said shafts and are adapted to be ro-- tated on their own axes by the pinions 38-38 whichare attached to said rolls and mesh with the beveled gear 39. This gear is fixed to the lower end of the upright shaft 40 which extends up through said bushing and through the upier bearing 30 and has the large gear 41 xed to its upper end.
v This main upright shaft 40 is rotated direct gear by means of the worm 48 mounted on the shaft 49,-through the pulley 50 mounted onshaft 44, belt 51 and pulley 52, which latter pulley is mounted on said worm shaft 49.
Another feature of this invention is that the rolls 37-37 may be removed from their respective spindles and square, rectangular or poly-faced blocks, such as that represented in Fig. 9, may be covered with polishing or finishing material, means for tightenin and retaining which may be mounted in said block, if desired. This block is also provided with a center bore to receive the roll shaft onto which said block may be secured. In order to raise and lower this head I have provided a hand operated lever 53 which is pivoted to the frame at 54, the lower end of said lever being pivotally connected at 55 to the sliding block 56 on one end of the connecting rod 57. The opposite end of this rod is connected to the lower end of arm 58, the upper end of said arm being fixed to the shaft 27, see Figs. 1 'and 2. Springs 59 and 60 are arranged to engage either side of said sliding block 56, whereby a yielding pressure may be applied to the rolls while in operation, and, when it is desired to adjust and regulate this pressure or raise the rolls entirely from the floor the handle 61 is raised to withdraw the spring actuated latch bolt 62 from the notched plate 63, allowing said lever to be moved and retained in any position to obtain the result desired. The tension of these springs may be regulated by means of the threaded nut 64.
The carriage is moved in a forward direction through the gear 65 which is mounted on the forward wheel shaft 8, see Fig. 5, gears 66 and 67, worm gear 68 and worm 69, which is mounted on the shaft 70, which shaft receives its rotary motion from the mo tor 2 through the pulley 71 belt 72 and pulley 7 3, see Fig. 1. \Vhen it is desired to reverse the rotation of the driving wheels 66 and move the carriage in the opposite direction a third, or idler gear 74 is provided which meshes with the gear 66 and is held in mesh with said gear by means of the bearing plate 75, which plate is pivotally mounted on shaft 76 and may be caused to swing gear 74 into mesh with gear 65 at the same time carrying pinion 66 out of mesh with said gear, when by driving from pinion 67 through pinion 66 and 74 gear 65 will rotate in the opposite direction and move the carriage backward. In order to operate and throw these gears to control the directionof the travel of the machine, an operating handle 77 is pivoted at its lower end on the pin 54 and is connected to the upper end of the gear bearing plate by the arm 78 and connecting rod 79, whereby the raising of the spring actuated latch bolt 80, by the hand lever 81, will enable said lever to be moved and throw the gears either out of chine is not in operation the head ceases mesh altogether with gear 65 to stop the carriage, or into position to drive the carriage either forward or backward. When it is desired a hood, not shown, may be placed around the surfacing rolls and connected by a pipe, .not shown, to a blower 82 whereby the dust and waste material raised from the floor may bedrawn from said hood forced up through the .pipe 83 and into the receiving bag 84. v a l The operation of this device may be more fully described as follows: When the ma-' controlling handle 53 is moved into the u right position, which raises the rolls-clear of the floor. The carriage guide handle may then be withdrawn from its socket 15 and spring lock bolt to draw and guide the, carriage into the position desired to commence the operation.
Then as it is usually desired for the carriage I operating upon the same as it goes. When the end of theroom is reached it is only necessary to move the reversehandle 7 7 from its forward to its back position when the carriage immediately reverses its motion and moves in the opposite direction.
.An important feature 0, the invention is that the whole character of. the machine may be changed and the surfacing rolls instead of receiving a double mot-iom-which is that of rotating on their 'own axes and also around a common center, may be fixed by simplyv removing the worm driving belt 51 which will lock the bushing 34 and fix the rolls so that they will not rotate around a common center but only rotate on their own axes. In this way two of the rolls are set at right angles to the direction of travel while the other two rolls are removed from their respective shafts.
duced is entirely changechrendering the ma chine adapted to clean the floor and produce a bright and finished surface much quicker than evenness in the surfaces over which they-may pass while dressing the same.
This machine renders itself doubly valu- By thus altering the machine the character of the work proed rom said carriage, a rol sald head, a sleeve 1n sa1d head for carrying able by being ada ted to be altered so as to accommodate itse of work desired.
Having thus described my invention, what I claim as new and desire to secure by Let ters Patent,- is:
