In the drawings like characters of refcreme indicate corresponding parts in the several figuresf The "various working parts of the me- I chine otherthan" the motor and the carirage wheels are housed within a casing 1 of a suit- 'ablh design, the casingoeing provided,"01"-d wardly within" filling opening 2 cLndreafi wardly of the filling opening withnn inclinedbearingiace 3 to which anelectric motor 410i anynp'proved design is fastened hy bolts 5.. A filling ca dcovers the open- 0 mg 2 and the back end 0 the casing is closed by aremovable back 7. fastenedhy removable screws 8 to the casing sides. r

Rearwardly the-casing is ed nstebIy supported 'by *gcen trellv located caster-wheel 9 35 and forwardly it is adjustably supportedby similar carriage wheels 10 and 11, the

structural details of "which are hereinafter 1 described. A forked arm 12'is attached to the sides of the casing and is rovided "with go suitable handle 13. jward part ofthe casing is provided with :transverselyextending, horizontal and verti "Intemorly the forcol partitions-'14 and 15 which confine enforend ofthc motor shaft 18- i s i On the lower end of the motor shaft I mount a bevel pinion 19 fastened thereto by a jam screw 20 and above the pinion the motor shaft presents a spiral thread or worm 21. The partition 15 is provided with a bearing 22 which rotatably supports a short shaft 23 having one end provided with a gear wheel 24 meshing with the bevel pinion 19 and the other end fitted with a paddle 25 operating in the rear part of the compartment 16. The gear wheel and paddle are fastened to the shaft 23 by jam screws26 and 27.

It will be observed that when the bevel pinion 19 is meshing with the gear 24, there is a clearance space underneath it. This is provided so that if I do not desire to operate the paddle I can release the screw 20 and thereby permit the bevel pinion to slip down into a position resting on the bearing lug where the said pinion will be out of mesh with the gear wheel.

The removable back 7 carries a pair of similar spaced bearing brackets 28 and 29 which extend inwardly of the casing and carry similar aligned bearings 30, the bearings supporting rotatably a counter shaft 31, the ends of which are provided outside the bearings with cranks 32 and 33 disposed 180 degrees apart. Between the bearings and on the shaft, I mount a worm wheel 34 which is fastened to the shaft and which is driven by the worm 21.

For-wardly the casing is provided with four horizontally disposed suitably spaced sockets 35 and the removable back 7 is also provided with four suitably spaced horizontally disposed sockets 36 and these front and rear sockets are utilized to support four tubes or ipes 37, 38, 39 and 40 arranged in pairs. am screws 41 are provided to fasten the ends of the pipes in the rear sockets. According to this arrangement, when the back 7 is removed, the pipes pull out of the front sockets and accordingly withdraw from the casin with the back.

The inner tubes or ipes are provided centrally of their lengti and on their under sides each with a feed opening 42 and the forward end of each casing is provided with interior branching ducts 43 and 44 which communicate through the front bosses with the interior of the latter pipes or tubes. The meeting ends of the ducts open through the bottom of the partition 14 to the compartment 16 and an adjustable valve 45 is supplied for controlling the flow from the compartment throughthe ducts, the stem of the valve being screw threaded and mounted in the casing and the upper end thereof being supplied with a finger piece 46 for adjustment purposes.

The pairs of tubes carry carriages 47 and 48 and as the carriages are both of similar construction the description of one will suffice. Centrally on the upper side the car riage presents spaced upstanding lugs 49 and 50 and it is provided also with lengthwise extending parallel holes 51 and 52 adapted to slidably receive a pair of the rods or pipes. In this way each carriage is slidably mounted for endwise reciprocation on the rods and the carriages are reciprocated by links 53 and 54 attached to the cranks at one end and having the other ends fastened to the lugs 49 and 50 by pivot pins 55. The under sides of the carriages are hollow or open and they present substantiall rectangular frames which receive block like holders later described. The amount of reciprocation given the carriages by the cranks is such that the feed openings 42 never pass outside of the carriage walls or frames.

The carriages are utilized to carry the various floor working attachments which will obviously require to be changed depending on the nature of the work to be done on the floor. When it is desired to apply a liquid such as oil or wax on the floor. I utilize a substantiallyrectangular block-like holder 56 for each carriage, each holder being provided on the top face with a rectangular rim 57 adapted to pass into the carriage frame and being provided at the ends with transverse end slots 58 and 59 and having the interior thereof providing a liquid distributing compartment 60 presenting a perforated bottom as indicated at 61. I

might here point out that the ends of the carriages and the ends of the holders above the slots, both converging upwardly, such construction being best shown in Figure 3.

The holders are detaehably fastened to the carriages by similar pairs of end clips 62, these clips each being provided with side arms 63 and 64 fastened to the sides of the blocks by similar screws 65. Each clip also is provided with an-inwardly extending and downwardly inclining jaw 66 which has the lower edge thereof provided with a row of teeth 67. The jaws are adapted to enter the slots 58 and 59.

When a floor cloth 68 is to be attached to the holder, it is spread over the bottom face of the holder and the ends of the cloth are entered in the slots, it being understood that at this time the holder is free of the carriage and accordingly the upper ends of the spring clips can be swung inwardly over the holder to clear the jaws from the slots. The ends of the cloth having been placed within the slots, the upper ends of the clips' are then ulled outwardly and such action causes the aws to move in and grip the ends of the cloth and hold it in place as best shown in Figure 5. The holder with the cloth so attached is then laced on the carriage, the upwardly extending and inwardly converging ends of the clips at this time being slipped up the ends of the carriage. The

lUU

floor cloth resiliently resists the outspreading of the upper ends of the clips so that when the holder is finally in place, there is enough pressure exerted by the floor cloth on the clips to hold the holder in place on the carriage. This arrangement of clips provides a very convenient fastening not only for the floor cloth but also a very simple method of demountably attaching the holder to the carriage. Whilst I have mentioned a floor cloth, it will be readily understood that sand paper or other strips of material which might be required for working on a floor, could be attached to the holder in the same manner as the floor cloth described.

When the several floor cloths have all been attached to the holders and the holders placed on the carriages, it will be apparent that the floor cloths will be reciprocated by the running motor and that the liquid from the compartment 16 can flow to the floor cloth, the amount used depending on the setting of the valve 45. Here it is explained that the liquid flows down the ducts and into the innermost tubes and from the tubes through the holes 42 into the distributing compartment 60 and through the perforations 61 to the floor cloths. The rapid reciprocation of the carriages will cause the liquid admitted to the compartments 60 to be distributed well over the perforated bottoms of the compartments so that there will be an even distribution on the floor cloths.

If sand paper or other strips are to be used which require no liquid, one will naturally close the valve to prevent the feed of the liquid from the compartment 16. When it is desired to polish say a Waxed floor, I provide similar brushes 69 which can be used instead of the holders 56. brushes have the backs thereof constructed to seat in the carriage frames in the same manner as the holders and they are provided at the ends with similar spring clips 70 fastened by screws 71 to the ends of the brush and adapted to clip on the inclined ends of the carriage.

The caster wheel 9 is provided with a shank 7 2 which isrotatably mounted within a sleeve-like bearin 73 secured to the back 7 of the casing and t e shank is also'mounted so that it will slide endwise within the sleeve. An adjusting screw 74 is carried by the sleeve and engages the upper end of the shank and a jam screw 75 is provided for locking the adjusting screw in any set position. Obviously upon the adjusting screw being screwed down, the shank will be shifted downwardly and such will cause the raising of the rear end of the casing from the floor.

The carriage wheels 10 and IL are mounted in the following manner. Each side of the casing is provided with vertical guides 76 and 77 which receive slidably These therebetween a block 78. The block carries a horizontally disposed spindle 79 which extends outwardly between the guides and on the spindle I locate a sleeve 80 on which the carriage wheel is rotatably mounted. The free end of the spindle is screw threaded and carries a jam 'nut 81 which engages the outer end of the sleeve. Accordin to this arrangement I can adjust the spindle in each instance byundoing the nut, then sliding the block between the guides u or down as required and then tighten up the nut to cause the sleeve to jam against the faces of the guides and in so doing frictionally hold the block in its adjusted position. Whilst I have described in detail the manner in which the carriage wheels and castor wheel can be adjusted, it will be readily understood that I do not desire to be limited to such particular construction as anyocon venient adjustable arrangement of these wheels will suit my purpose.

I wish here to point out that all the working parts of this machine can be readily inspected or removed when desired and in this connection, it will be apparent that if the screws 8 be removed, the back of the casing will pull out and will carry with it the brackets, the crank shafts and parts associntcd therewith, the tubes and the carriages. This being done, one can readily inspect the lower end of the motor shaft; and the bevel gear and pinion.
