' CORNER-BEAD-POSITIONIING DEVICE.

Application filed June 12,

My invention relates to corner bead positioning devices of the character elllbOdlGfl in my co-pendmg application Serial No.

alt is a purpose of my present invention to i-provide' a corner bead positioning device by which the corner beads of single. or double side pilasters'can, with facility and dispatch,

' be properly positioned bothvertically and completed. 1

' a, Similar reference characters refer to similar parts-in each of the several' views. I

Referring specifically to the drawings,and

particularly to Figure 1, my invention in its present embodiment comprises a pair of units, and as the constructlon of the two units 'is identical a description of one will integral with or welded to the arml'fl while ing'a set screw 18. The arm is constructed from a channel bar which may be formed the latter has the cross sectional contour shown in Figure'fl." The frame Fv comprises a relatively short arm 19 of the same construction as the arm 15-and provided witha clamping screw 20. The frame F also includes along arm 21 m the form of a I 7 channel bar of suclidimensions as to he slidablyre'c eived within thearm 17 of the frame F and tereagh the medium of the setserew' 1926. Serial no; 115,565.

18 the arm21 is capable of being locked in any longitudinally adjusted position within the arm 17 so as to vary the parallel relation of the arm 19 with respect tothe arm-15. I x

The

arms

15 and 17 have slidable thereon so i,

brackets

22 and 23, respectively, capable 'of' being locked in any adjusted position by means of

screws

24 and 25, respectlvely.

These brackets co-operatewith the'arms in providing clamp for securing a corner head? to the frame inthemanner shown I in Figure 2. By virtue of thefact that they are adjustable, it will be understood that'the brackets are capable of clamping the vari- 011381285 of corner beads. The frame F 'is provided with a simllar bracket 26' adjustable on the arm 19 and capable of being locked in adjusted position by'a screwv27i This bracket 26 isadapted to co-operate with abra'cket 28 which, as shown in Figure '5, is disposed within thearm 21 and is slotted'to receive a' screw 29 by which the bracket can be locked in longitudinally adjusted po-- sition on-the arm. The head ofithe bracket bracket B in the frame F.

In practice,the two units are associated,

with a pair of corner beads B and'.B.".in the manner illustrated in Figure 1, the'beads being securely clamped by means ofthe brackets, 22 and 23, etc., thus servingto' maintain the units in spaced relation. 7 The."

device is now ready to be applied to a double face pilaster in the manner shown in Figure 2, with the clamping screws .16 and 20 disposed to engage the sides of-the p'i- I laster and when screwed into clamping enY- i gagementwith the pilaster to secure the two units in horizontal, position, oneabove the other, and to thus-properly position the corner bea dswith respect to the corners of the pilasterr Various methods of positioning the twounits'to effect, the proper supporting of'the corner beads may-be'employed; By firstdetermining the points at which the-clamping

units so that the corner beads will occupy perpendicular positions atthe corners of the pilaster.

When once clamped to the pilaster the two units serve to rigidly. support the corner beads in proper position atthe cornersof the pilaster so that the plaster can be applied in the usual manner on the corner ners ofthe pilaster.

beads, and thus'be properly positioned within the plaster. r

Itwill be understood that the two units arevcapable of adjustment to accommodate the device to pilastersof different sizes, and as the co'rner bead brackets are likewise capableof adjustment to accommodate different size beads, it will be manifest that the device in its entirety is capable of universal use in its'adaptation tovarious slzes of pilasters and the holding of corner beads 1n variousspaced positions with respect to the cor- ,Referring now to Figure 6, I have here shown a modification of the device, in which the frames F of each ofthe units only is employed, and in conjunctionwith a frame F having a long arm 31 slidable in the arm 17' and capable of beingiocked in any ad justed position by the screw 18, and a short arm 32 adapted to engage a strip of plaster of Paris 33 which may be applied to the front of a single side pilaster as shown in Figure 6. The flat side of the strip 33 is made perpendicular so as to form an abutment against which the'short arm 32 of each frame F depends, and with the two'units embracing a corner bead B as shown in Figure 6, it will be clear that the two units cooperate in supporting the corner bead in perr.

pendicular position with respectto the corner of the pilaster and to securelyrhold the same in applied position whilethe plaster is being applied. 7

Although I have herein shown and described only two forms of corner bead-positioning devices embodying my in'vention, it is 'to be understood that. various changes and modifications may be made therein withoutdeparting from the spirit of the invention,

and the scope and spiritof the appended claims. 7

I claim: 1. A device for positioning corner beads with respect to pilasters comprising means adjustable to clamp a-pilaster so as to be with respect to pilasters comprising a pair of L-shaped frames extensibly connected in the form of a U, clamping screws carried by the parallel portions of the frames, and corner bead engaging brackets arranged in pairs on the framesand coacting to clamp corner beads to the frame,

4-. A device as embodied in claim 3, wherein one of the brackets of one pair is provided with a shouldered surface alined With'respect to the inner surface of one arm of the other frame for the purpose described.

5. A device for positioning corner beads with respect to pilasters comprising a pair of frames extensiblyr associated with each vother and havinglaterally projecting-por tions betweenwhich a pilaster is adapted to be received, means on said POlSiJlOIlSblY which the frames are adapted to be clamped to the pilaster, and means on the frames for sup porting corner beadson the frames 1n proper position with respect to cornerslo'f the pilas-' ter.

6. A device for positioning corner beads with respect to pilastersrcomprising means contractible to engage a pilaster, means for clamping the first means to the pilaster so that the first means will be supported in elevated position on the pilaster,and means on the first means for holdinga corner bead K thereon to properly positionthe latter with respect to a corner of the pilaster.

7, A device for positioning corner-beads with respect to p ilasters as embodied in claim 5 wherein the last means comprises brackets arranged in pairs and slidable on the frames for engagementv with the corner beads, and means by whichthe brackets are adaptedto be secured to'the frame in'clamping' relation to the cornerbeadsL p 8. A device for positioning corner beads with respect to pilasters comprising a. palr'of substantially L-shaped frames telescopically associated'with each'other' in-the'form of a U, clamping screws carried by the parallel portions of the frames, corner bead engaging brackets slidable'on the frames, said brackets arranged in pairs with the brackets of each pair co-acting to clamp corner beads therebetween, and means for securing'the brackets to the frames in clamping relation to the corner beads. 1

9. A device for positioning corner beads with respect to pilasters comprising means adjustable to engageand support itself on the pilastor, means for clamping a corner bead to the first means and comprisingbracke ts movably mounted onthe first means and between which the corner bead is adapted to be interposed, and means for securing the brackets against movement in clamping relation to the corner bead so as to support the latter in proper a corner of the pilaster.
