SHADE-ROLLER HOLDER.

Specification of Letters Patent.

' Patented July 25, 19ML Application lecl May 2, 1914. Serial No. 836,012.

To all whom t may conce/Mz Be it known that I, PAUL CLARKE SHA1- rnn, a citizen of the United States7 residing in the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Shade-Roller Holders, of which the following is a speciiication, reference being had therein to the accompanying drawings, forming part thereof.

My invention relates to means for attaching metal shade roller brackets to metal window casings or parts thereof, such as to the metal trim, commonly to the sheet metal stop strips of the sheet metal casings largely employed in ireproof building construction. These brackets, usually punched from sheet metal, have heretofore commonly been attached to the comparatively thin sheet metal stop strips, or similar sheet metal casing part, by means of screws each holding by only about one and one-half turns of the thread, giving very insecure attachment of the shade roller brackets; `and moreover, the tapping and threading of these screw holes occur with the stop strip or other sheet metal casing part in position, and eX- act spacing and perfect threading of the screw holes are diilicult of attainment. Furthermore, the screws are so small that they cannot be handled quickly without dropping them, and much time is thus consumed.

My invention aims to provide Yfor the ready attachment of shade roller brackets with simple and quickly performed operations whereby the brackets are securely fastened and held.

My invention includes a metal bracket having attaching tongues preferably integral therewith projecting `through holes in the casing part to the back or inner side of the casing part and there clenched by access had from the outside through) free vspaces in the holes through which the attaching tongues project.

My invention further includes other features of construction and combinations of parts, as will` appear from the following description.

I shallnow describe the embodiment of my invention illustrated in the accompanying drawings and shall thereafter point out my inventionin claims.

Figure l is an inside elevation, the upper left corner portion of a sheet metal window frame or casing having a sheet metal stop strip and sheet metal shade roller bracket embodying my invention, the sash being omitted. Fig. 2 is an elevation, partly in section, as viewed from the right in Fig. l. Fig. 3 is an elevation similar to Fig. 2 of the upper right corner portion of the casing and corresponding parts. Fig. l is an elevation of the left hand shade roller bracket of Fig. l in position ready for attachment tothe stop strip shownin vertical section. Fig. 5 is a vertical section of the bracket and stop strip with the attaching tool in side elevation and the upper one Yof the attaching tongues of the bracket partly clenched. Fig. 6 is a similar view lwith the upper tongue of the bracket completely clenched by the other end of the attaching tool. Fig. 7 is an invertedplan of the attaching tool as seen from below in Fig. 5. y

The left stop strip l (Figs. l and 2), right stop strip 2 (Fig. 3), left shade roller bracket 3 (Figs. 1, 2, 4, 5 and 6), and right shade roller bracket 4; (Fig. 3) ,in all respects not involving my invention, are of usual construction. The sheet metal stop strips 1 and 2 are carried by a usual sheet metal frame or casing 5, these stop strips being of hollow trough shape molding form, as appears in the cross-section ofthe upper stop strip 6 (Figs. 2 and 3), leaving a 'considerable open or free space within the stop strips between the stop strips and the inner face of the casing 5. The shade roller brackets are stamped out and punched from sheet metal as heretofore. The left bracket 3 has the usual slotted outwardly project 9 ing central shoulder a for the reception o the winding stud of the usual shade roller,

i and the right bracket 4 has the usual apertured central shoulder for the reception of the pivoty stud of the shade roller.

The brackets 3 land l have similar flat base portions c provided with rearwardly projecting attaching-tongues or attachingprongs Z shown as struck down or punched from the central portion of the base c so as to leave an opening in the base, the cut made by the punched out tongue Z not extending to the edge of the base. The fiat attaching tongues l for each bracket 2 and 3 are shown as turned'back toward each other so as to 'project substantially perpendicularly from the base c, as appears in Fig. 4, and it will be noted that the base or point of origin of each tongue d is adjacent to the central' ing ktwo holes corresponding to the two tongues of each bracket and the holes e be'- ing spaced apart so as to snugly receive the projecting attaching tongues l (see Fig. 4 particularly). This larger diameter of the tongue-receiving holes c and snug spacing of the attaching-tongues cl leave free spaces in the holes e outwardly from the central shoulder a. or b sufliciently large to permit the tongue Z to be clenched through the free space by means of a specially formed tongueclenching tool 7 (Figs. 5, 6 Vand 7). It will be knoted that these free spaces in the holes e beside the tongues d are of substantially semicircular shape.

-the backward curve of the handle portion f The tongue bending tool 7 is vof strong metal, such as steel, and has a middle slightly curved handle portion f, an initial tongue-clenching end portion g projecting fat an obtuse angle to the handle portion,

and has, at the other end of the handle portion f, a final tongue-clenching end portion bent on a curve to project substantially at right angles to the handle portion f. The tongueclenching portions g and z, are shown as projecting from the same side of the tool and-the curve or Vgradual bend of the handle portion f is ina backward direction from the projecting tongue-clenching end portions g and la, so as to prevent accidental twisting of the tool in the hand in use. Also rprovides for the insertion of the tool in the lower tongue-receiving hole c by permitting the free end of the tool to. clear the upper stop strip, 6.VK It should be noted that the tongue-clenching end portions g and z are ofv substantially semicircular shape in crossoksection to correspond with the shape ofthe free Vspaces lefty in the holes e beside the tongues d, these bent end portions g and it being flattened on their sides adjacent to the handle portion f. The attaching tool 7 is provided withfulcrum shoulders 'i between each of the tongue-clenching end portions g and z. and the intermediate handle portion f, for limiting the insertion or extent of entrance of these tongue-clenching portions through the tongue-receiving' holes e, these shoulders being shown as ofV substantially circular shape flattened on their lsides adjacent to the bent end portions g an Y d h. f In the operation of attaching a shade roller bracket to carry out fully my invention the tongue-receiving holes e, properly vimpossible to properly .tongue d. It should be noted (see Figs. 5

spaced andY of correct diameter; are iirst drilled in the sheet metal casing part, such as the stop strip 1. Next the shade roller bracket, for example, the left bracket" 3 shown in Figs. 1, 2, 4, 5 and 6,is placed in position with the perpendicular attaching vtongues d projecting through the tonguereceiving holes c,A for example, in the upper hole, in the semicircular free space lbeside the attaching tongue al. The right-angularly bent end portion It of the tool could not be first inserted, as the projecting central shoulder,such as a, would obstruct the way, but the slightly bent portion g will slip past this central shoulder. The tool 7 is then brought to the position illustrated in Fig. 5, to 'eiiect an initial bending overY or partial clenching of the attaching-tongued, as clearly appearsin this ligure. Afterthe initial bending of the attachingutongue d illustrated in Fig. 5, the clenching tool 7 is reversed end for end and the 'right-angularly bent tongue-clenching end portion 71, is inserted in the free space beside the partially 'clenched tongue, the initial bending Yot the tongue permitting such end portion d to be inserted in the hole e past the pro- The tool 7 is then jecting shoulder a. brought tothe position illustrated in Fig. 6,

to effect a final bending over and clenching of the attaching tongue d, as is clear from this figure.y The tulcrum shoulders z' in each yinstance make possible the application of' Y power lso as to bend over and effectively clench the tongue d. Without such'fulcrum shoulders, the tongue-clenching end portions g and It would-have a tendency to slip too far through the hole e, j

clench the attachingand 6) that the fulcrum shoulders i rest upon the projecting` end portion of the base thereby rendering it 1 c, whichserves as a fulcrum for the fulcrum yshoulders of the attaching tool, obviating any possibility vof denting Aor scarring the ,comparatively thin sheet metal stop strip l.

Y After one ofthe attaching-tongues 'dV has then the other tongue 'is similarly clenched, to fix the bracket 3 iirmly and securely in :place on the sto-p strip 1, as illustrated in In some instances the lower of the two attaching tongues Z maybe left unclenched or may be dispensed with, since the upper tongue Y alone will *quite :firmly hold the bracket in place. With both tongues been Vsecurely clenched, asjust described,"

clenched, however, the bracket is very firmly held, the tongues being preferably clenched oppositely as shown and turned over toward each other, so that the clenched tongues firmly engage and grip the sheet metal stop strips 1 and 2 at the back.

It is obvious that various modifications may be made in the construction illustrated in the drawings and above particularly described within the principle and scope of my invention.

I claim:

1. A structure embracing coperating parts, the one being a sheet metal shade roller bracket provided with a projecting attaching tongue, the other being a sheet metal casing part provided with a recess for the tongue permitting passage of the tongue therethrough and access to the tongue from the outer side to bend the tongue into engaging position.

2. A structure embracing coperating parts, the one being a sheet metal shade roller bracket provided with a plurality of projecting attaching tongues, the other being a sheet metal casing part provided with a corresponding number of recesses for the same permitting passage of the tongues therethrough and access to the tongues from the outer side to bend the tongues into engaging position.

In testimony whereof I have aiiiXed my signature in presence of two witnesses.

PAUL C. SI-IAFFER.
