SCREED ANCHORING AND LEVELING DEVICE.

vApplication ledvMareh 10, 1924, Serial No. 698,157. Renewed November 21, 1928.

l ing the screeds tothe anchors,to place wooden wedges `or the like between the concrete baseand the under surface of the sleepers.

' The rforming of these .wooden wedges and the placing of them in position requires considerable time and is, therefore, expensive, as it must be done by skilled workmen. Furthermore, when these wooden wedges have been placed in position,fit is customary to rdrive nails through the screedsinto the wedges and hold them inppositionagainst shifting about. It is also customary, after the screeds have been leveled and supported by the wedges and nailed tothe screed anchors, to fill up the space. between the under ysurface of the screed andthe concrete Vbase with concrete.

The `object of ,my invention is to provide a combined screed anchoring andleveling device of simple, durable and inexpensive construction, whereby the processof leveling screeds and connecting them to the anchorsy may be accomplished in a convenient, facile and economical manner, and whereby the time and expense of making and cutting down wooden wedges and nailing them to the screeds to prevent shifting about may be entirely dispensed with.

invention consists Ain the construction, arrangement, and combination of the various parts of the device, whereby the objects contemplated ,are attained, as hereinafter more fullyset forth, pointed out in my claims, and

illustrated in the accompanying drawings, inV

which: l

Figure 1 shows a perspective view of a screed anchoring and ,leveling device embodying my invention. n

Figure 2 shows a side elevationv of same with a portion of a screed mounted thereon.

Figure 3 shows a vertical, central, sectional view through twoadjacent screed anchoring and leveling devices mounted ina concrete base, which is shown in section, and supporting a screed.

Figure 4 shows a perspective view of the screed anchoring and leveling device showing a modified form of my invention.

Figure 5 shows an edge view of same mounted in a concrete base and having a screedtherein. The dotted lines show the adjusted position of the screed when the wedges are driven into their inner limit of movement. Y

Referring to the accompanying drawings, it will be noted that the entire device, as illustrated in the preferred form, is formed com-` plete of a single piece of sheet metal, and comprises a body portion l0 with two upwardly extended screed supporting members 11 on opposite sides of the body, and two downwardly extended-anchoring members 12 on opposite ends of the body portion. A portion of the material of which the anchoring members 12 are formed is cut out and normally extended parallel with the body portion and forms the two Aleveling members 13. Suitable openings 14 are formed in the screed engaging members to receive nails l5. v In practical use with the preferredform of my invention, the anchoring members of the screeds are placed in the concrete base before the concrete has set and hardened, the leveling members 13 being above the base, 'and preferably lying in a horizontal position. After the base has set and hardened, the wooden screeds are placed in position resting between t-he screed engaging members ll. Before the screeds are placed in this position,the leveling members 13 are inclined upwardly and outwardly, as shown at the right in Figure 3. Then when a screed is brought to the desired levelby pressing downwardly uponit, and thus bending the` leveling members, and when `v the proper ,level is reached, the screed engaging members 11 are `nailed to the screed. Theny the operator proceeds to pressthe screed downwardly at various points throughout its length to the desired level, and nail the screed engaging members to it, at as many points as may be necessary. vAfter the screeds are thus leveled and supported, then the operator places concrete under the screeds and around the screed vancors .to firmly support the screed at its bers and upwardly extended screed engaging members indicated generally by the reference numeral 16. Formed in each of the upright screed engaging members are two vertical slots l?, the lower edges of which are substantially flush with the top of the central horizontal meinber. The screed leveling members are :ach formed complete of a single piece of sheet metal comprising a central portion i8 and two wedge shaped end menibei's l5) at right angles to the body portion i8, and these wedge shaped members are each preferably pro vided with a raised, outwardly extending rib 20 to yieldingly engage the sides of the slots 17 and hold the leveling member in any position of its movement within the slots.

In use with this form of the invention, the screeds are placed in the anchors in the Imanner before described, and then the leveling` wedge devices are inserted in the slots and driven in until they engage the under surface of the screed at its proper point of elevation., and then the screed engaging members are nailed to the screed.

ln Figure 5 l have shown these screed leveling wedges in solid lines driven into proper position relative to the screed, and by dotted lines I have shown the screed separated a greater distance from the base and their wedges driven in farther to engage its under surface. These wedges, by being connected to the anchors and by having yielding or frictional contact with the sides of the slots in the anchors, will not become displaced after they have once been driven into position, but will hold the screed at the proper elevation until it is lirmly attached to all of the anchors, after which the space between the screed and the base is filled with concrete.

l claim as my invention:

l. A screed anchoring and leveling device formed from a single piece of sheet metal having'an anchoring member designed to be secured to a base, a screed anchoring member, and means mounted on said base anchoring member for adjusting the level of a screed before being secured to saidy anchor.

2. A screed anchoring and leveling device formed of a single piece of sheet metal, having a downwardly extending member designed to be mounted in a concrete floor, and an upwardly extending member designed to be secured to a screed, said device being provided with vbendable means for adjusting the level .of a screed before it is permanently secured in position to said upwardly extending member.

8. A screed anchoring and leveling device formed of a single piece of sheet metal having a horizontally extending body portion and a pair of downwardly extending inembers designed to enter a plastic concrete base, said body portion being provided with a pair of upwardly extending screed anchoring members, and also provided with a pair of laterally extending bendable members adapted to engage the under surface of the screed f and to temporarily support it in position relative to said anchors before being secured thereto.

ll. A screed anchoring` and leveling device rformed of a single piece of sheet metal having a horizontally extending body' portion and a pair of downwardly extending meinbers designed to enter a plastic concrete base, said body portion being provided with a pair of upwardly extending `screed anchoring members, and also provided with a pair of laterally extending bendable members adapted to engage the under surface of the screed and to temporarily support it in position relative to said anchors before being secured thereto, and means for rigidly securing said screed to said screed anchoring members.

5. A screed anchoring and leveling device comprising an anchoring' member designed to be secured to a base, a screed engaging` member designed to be secured. to ascreed. and an adjustable leveling member, said screed engaging member and said leveling member being capable of movement to a posit-ion flat against the base to which the anchoring member is secured. f

6.
