STENQiI-HOLDING' PPA ATUS. 1

To all whom it may-concern:

Be it known that I, CLARENCE-E. HARRIS, a citizen of the United States, and resident of Milwaukee, in the county ofMilwaukee and State of Wisconsin, have-inventedceirtain new and useful Improvements in" Sten cil-Holding Apparatus; and Ido hereby=de-' clare that the followingis a full, clear, and exact description thereof.

My invention relates" to new and useful improvements in means for holding a stencil against a surface to be decorated.

In stenciling walls or ceilings, it is-cus-' tomary for two or more"workmen to hold the stencils in place, while anotherworkman applies the decorating fluid. In addi tion to the number of'workmen required this operation, "the operation of holding the stencils is exceedinglyiirksome' and tiring,

this conducing to difficulty in securing labor for the operation, in addition to the normal expense of'such labor.

It is therefore primarily the object ofmy invention to provide meansfor mechanically holding the stencil against the ceiling or other surface to be decorated.-

In stenciling a ceiling, a support-for the operator and his equipment is usually afforded by scaffold boards, which are-sus-'- ceptible to considerable flexure as the workman moves about thereon: It is therefore a further and important object of my invention to provide a stencil holding device wherein compensation is'automatically afforded for the yielding movements of the scaffold board onwhich it is mounted.

A further object of my invention is toprovide a device of this character which is fully adjustable in nature to adapt it for different sizes of stencils and for difierent uses to which it may be adapted,also to firmly hold a stencil against a slanting ceiling portion. A further object of my invention resides in the provision of a stencil holding unit which may be manipulated for holding a stencil either against the ceiling or wall of a room.

With the above and other objects in view, whichwill be apparent as the description proceeds, my invention resides in the novel features of construction, combination and arrangement of parts as hereinafter described and defined by the appended claims, it being understood that changes in the precise embodiment might be made by those Specification of Letters iatent.

One of'the-yo'kes has set screw 9 threaded in its bight wherebythe inter-L mediate and lower sectionsmay be held against sliding movement to adapt the device for use under differing conditions in-- volving variablee distances between the ceiling and the scaflold or other support on.

which the standardmay be mounted. The

upper section 7 is resiliently-urged upwardly by; anexpansile spring 10 coiled'on the upper rounded portion of the intermediate section 6 and engaging the lower end of said section 7. A clamp collar 11 is fixed on the upper end of the standard section 5 and receives a crosshead bar 12, said collar being provided with upstanding ears receiving a set screw for clamping the bar 12 against movement in the collar. A pair ofclarnp collars 1 1,'controlled by set screws 15 are mounted on the head [bar 12 for adjustment longitudinally thereon and each of these clamps carries an upstanding fixed jaw 15 and a pivoted jaw 16 engaged by a clampin screw 17 for supporting a stencil holding ar 18, said bar 18 being of a length adapted to accommodate a stencil of maxi- 11111111 width and being adjusted on the head bar 12 by means of the clamp bar 14: to accommodate the various ranges in lengthof the stencils used."

An ordinary stencil S maybe secured in any desired manner to the stencil holding bars, which, as shown particularly in Fig. 1, have their stencil engaging faces disposed in a plane spaced. considerably. above thei clamp collar 11 of the standard.

To effect this securement in the present embodiment of my invention, an elongated clamp plate 19 is provided for eachstencil holding bar, the outer side of each plate be Y ing bent at 20 and having hinge connectlons 21 with the outer-side ofthe bar. 'Th'einner sides of theplate are bent inwardly at 22 for most eflicient clamping engagement with the. stencil, and the plate is resiliently urged to clamp the edge of the stencil between it" -and thetopiace-of the holding ;bar.1 8 by springs2 coiled on the journal rodof its hinge connections 21, movement of the plate .7

"4L. in removal or insertion of the stencil is effected by suitable finger pieces. 1% projecting, therefrom;

In.- operation of the device, stencil is I mounted on'the holding bars in the manner described, the standard is then stood upon the scafiold or other support,.being adjusted in height so that the spring '10 resiliently urges the stencil bars into engagement with theceiling; ..Thus yielding movement of the scaffold board or other support is automatically taken up the spring to retain these stencil holding barsin' engagement With the ceiling. J Thedevice may be manipulated by.

aisingle operatorand with the stencil then held thereby the operators attention may be entirely directed to applying the decorating fluid to the stencil.

A'When itis desired to-hold a stencil to a; slanting ceiling as shown in Fig.3, the sup- I port standardof the'device is mounted in its usual vertical manner, and the stencil hold-- ing bars 18 are adjusted angularlytwith respect thereto in accordance with the slant of the ceiling. To prevent slippage ofthe-stencil holding bars on the slanting ceiling,

spurs 25 are provided the bars, having elongated slotted shanks adjustably secured to the bars by clamping bolts 26, these spurs. afi'ording-a' firm engagement with the ceiling Without damaging the same,

particularly'by reason-of the degree of adlustment afforded these spurs whereby they may engage-vertically in the ceiling in various angular positions of the holding bars.

When it is desired to hold a stencil to a wall, the upper standard section 7 is removed" from the other-sections thus, affording with the holding barsand'cross-head: bar, a unit which maybe readily grasped by .one hand hold the stencil.
