R. w. RowLEY PLASTERBR s FLOAT Filed Dc. 14, 1925 Patented May 3, 1927.

RAYMOND W. `nowmw, or sr. LOUIS, MISSOURI.


Application filed December` 14, 1925; Serial No. 75,233.

The object'of this invention is to provide al novel construction of plast-erers float which shall be characterized by simplicityA and durability of construction, lightness of weight, and economy in manufacture.

lVith the above objects in view, the invention resides in a plasterers float comprising a cork or other suitable face block, a back plate secured thereto in such manner as to prevent any of theconnections becoming eX- posed at the operating face of the float except after a relatively long period and excessive wear, and which connections present no projectingl parts on which the plaster can adhere, and a pair of` handle supports formed integral with the back plate.

The invention is illustrated in the accompanying drawing, in 'which-- Figure 1 is a top plan view;

Figure 2 is a section` taken on the line 2 2 of Figure 1; and 1,

Figure 3 is an enlarged sectional -View illustrating one of the plugs and assoclated hooks connecting the face block and back late..

p Referring to these drawings,thenumeral1 indicates the body or face block of the float, which is preferably made of cork, although it may be constructed of wood or any other suitable material. On its upper side, the body 1 is providedewith recesses 2, preferably four in number, located symmetrically at opposite ends of the body, as indicated in Figure 1. The cork body 1 is rectangular in shape and is adapted to be secured to a back plate 3, which is preferably made of aluminum. To this end, the plate 3 is provided with counter-sunk apertures 4 corresponding in number `and position to the recesses 2, and which are adapted to receive plugs 5 having heads 6 suitably shaped to be received into the counter-sunk portion of the apertures 4. Each of the plugs 5 is pro-v vided with a central screwthreaded aperture 7 (Figure 3), which is adapted to receive the screwthreaded shank of a hook 8. The

pair of hooks 8 at either end of the float re inthe recesses, the rods 9 are then passed through the openings 10 and through the eyes of said hooks, and then the plugs 5 are screwed onto the Shanks of the hoolisS. It will be seen that, when assembled, the heads @project vonly slightly abovethe upper face of the back plate 3 and thus present no projection on which plaster can engage. y Preferably, the heads 6 of the plugs are provided with transverse grooves 11 on `their upper ends to `facilitate screwing the same by use of a screw-driver or similar instrument.

The handle 12 of the floatis mounted-by a suitably headed bolt, or the like, 13 in sup-y ports 14, which are preferably made bycut-l ting through the back plate, as indicated at 15, to provide tongues, and turning the tonguesjupward. lHowever, the back plate with its supports maybe made as a casting instead of being stampedfout of a sheet of metal, as described. i'

Itl will be apparent from the described for connecting the back plate and face block '1, that the latter can neverproject `beyond the operating face ofthe float construction tended use; and such excessive wear` wouldv only occur after relatively longcontinued use of the float. When it is necessary to replace the body 1 with a new body, the parts may be readily disconnected by unscrewing the plugs 5 and removing the rods 9 by driving them lengthwise through said body. To facilitate the connection of a new face block to theback plate, I contemplate providing face blocks already prepared with the recesses 2 and transverse passages 10, sothat it will require but a very few moments to connect a new face block to the back plate.

While I have stated that the back plate and handle supports can be made as a casting, I prefer stamping the same Afrom a sheet of aluminuml in the interest of lightness of construction.

I claim:

1. A plasterers float comprising a faceA block having two pairs of engaging members located, respectively, near opposite ends thereof and provided with screwthreaded Shanks projecting above its upper side, transverse rods passed through the body of said face block and through said engaging members, a back plate applied to the upper side of said face block and having apertures through which said Shanks project, screwthreaded members applied to said shanks and screwed against said back plate, and a handle supported on said back plate.

2. A plasterers float comprising a tace block having two pairs of'recesses located, respectively, near opposite ends thereof-and opening from its upper side, a back plate,

having a handle, applied toy the upper side of said tace block, and means for securing sa'id baek plate to the tace block comprising engaging membershaving eyes located in" sa'idl recesses and screwthreaded shanks projecting upward through apertures in said back plate, rods passed transversely through the body of said face block and through saideyes,"an`d screwthreaded members screwed on ,said Shanks`r and engaging theupper side osaid back plate.

3: A p'laster'ers ioat comprising a face block having two pairs ot' recesses located, respe ively, near 'opposite ends thereof, opening fron'rits'upp'er side and extending to' substantially' the center of said block, engaging meni'bers having eyes located' in saidt recesses and provided with screwth'readedshanks projecting abovethe upper side of said block, transverse rods passed throur'h the body of said' face block and through said eyes, a back plate having counter-sunk apertures Correspending` in number and position to said recesses, and appliedto the upper side'o't' said" i'ace block, serewtlneaded plugs screwed on said shanks and having heads shaped tofbe received in the counter-sunk portion* of said apertures, and a handle supported on said back plate.

4". A plasti'ers float comprising a face block having' two pairs of recesses located, respectively, near opposite ends thereof, opening from its upper side and extending to substantially the center of said block, and transverse passages extending through said block from side to side thereof and cutting said recesses, engaging members having eyes located in said recesses and serewthreaded Shanks projecting' above the upper side et said 'lace block, rods inserted in said transverse passages and passing through said eyes, ab'ack plate applied to the upper side ot said block and having counter-sunk apertures corresponding in number and position :to said recesses, scren'ftlnea'ded plugs screwed on said Shanks and passing through said back plate into said recesses and having heads shapedto be received into the countersunk portion ofj said apertures, and a handle mounted onl said' back plate.

5. A plasterei"s tloat comprising a face block having two pairsof engaging members located, respectively, near opposite ends thereof and provided with extensions projecting above its upper side, transverse rods passedz through the body of said face block and through said' engaging members, a back plate applied to the upper side of said tace block 'and having apertures through which said extensions project, fastening members applied to said extensions and bearing against saidback plate, anda handle supported on said'baekl plate.

ln testimony whereof, I have hereunto set' my hand RAYMOND lV. RGVLEY.
