Application filed November 7, 1914. Serial N0. 870,725.
To all whom it may concern:
Be it known that L'STANISLAUS PnANIs,
a citizen of the United States, and a resiclamping the bracket in adjusted position;
to prevent the clamping cam from arring loose; toprovide clamping means which tendto displace the adjustable member in the plane ofthe base or supporting mem ber; to clamp the adjustable member toward-the base or supporting member, rather than away from it; to support the bracket arm against wabbling; to thus clamp the adjustable member and prevent it [from wabbling byma single locking member; to secure a simple, neat and inexpensive construction, and to obtain other advantages and results as may be brought out in' the following description. 1
Referring to the accompanying. drawing, in which like numerals of reference indicate the same parts throughout the several views, Figure l is aperspective view-of ashade bracket embodying my invention; Fig. 2 is a front elevation of the same; Fig. 3-is a detail perspective view of the adjustable member; a is a transverse section on line AA of Fig. 2 looking in the direction indicated by the arrows, and Fig. 5 is a detail perspective view of an adjustable member showing a modified form of locking means.
In the specific embodiment of the invention illustrated in said drawing,'the reference numeral 1 indicates a base plate, which is preferably constructed of sheet metal and provided with suitable holes 2, 2 therein for securing the same to a window frame or the like by means of screws (not shown). The base plate has bent over top and bottom edges 3, 3, that is, the edges are bent over towardithe front 'and'returned toward each other parallel to the body portion of the base plate and spaced therefrom, forming guideways 4, 4. An adjustable member 5 is mounted in said guideways adaptpreferably at. right angles thereto.
ed tobe slid to any desired position from one. end of the base plate to the other. This ad ustable member comprises a slide plate 6 from: which projects the bracket arm 7 The slide plate is arranged fiatwise of the base and of proper proportions so as to project at its top and bottom edges behind the bent overtop and bottom edges 3, '3 of thebase plate, thus preventing the member 5 from becoming dislodged by passing outward between the bent over edges. However, the ad ustable member is readily removed when desired. by drawing the slideplate longitudinally of the base plate and out of the end of the guideways 4, 4. The bracket .arm' 5 stands upon edge or transverse to the guideways and 1s of less height than the slide plate 6 so as to project between the'bent over edges 8, 23 0f the base plate. aid: arm preferably provides a socket or perforation 8 at. a distance from the slide plate 6. adapted to receive the end of the.
shade roller, and the outer end of the arm isturned upward and made narrow'as at 9,
virtue of said cam edge the entire edge of the slide plate opposite from the cam edge will be seated-firmly in its guideway 4 as a the cam is turned to engage its adjacent bent over edge 8, thereby not only frictionally preventing the slide plate from moving longitudinally of the base but also preventing it-from wabbling. It will be noted that the slide plate is not ,forced outwardly away from the base plate stall, the pressure being principally a tensile strain in the plane of the body portion of the base'tending to displace the slide plate in said plane or flatwise of the base plate and toward one of the bent over edges.
Obviously the 'cam' may bear against either the top or bottom I bent over edge 3, and for purposes of illustration the. same has been shown bearing against the top edge. Preferably said cam is pivoted substantially midway between the top and bottom edges of the slide plate so that it may be reversed in operation and. caused to bear against the lower turned over edge 3 of the base plate when so desired. Furthermore, the cam edge is preferably beveled toward the slide plate thereby allowing the same to gain a purchase between the bent over edge and the slide plate, pressing the slide plate positively toward the base plate to obtain greater frictional contact and rigidity. In this manner the slide plate is not only clamped edgewise toward one of the bent over edges but is also clamped fiatwise against the base plate and especially at the opposite end from that which is pressed against the bent over edge of the base. It will be understood by those versant in such matters that since the slide plate is positively prevented from wabbling the tendency for the cam to become loosened by the ordinary use of the device is reduced to a minimum, and furthermore the cam is retained in position by virtue of the pressure transverse to its direction of swing clamping the cam at its outer end between the slide plate and the bent over edge of the base plate.
Obviously the curtain rod supporting end 9 may be omitted if desired, and in this case the adjustable member could be used at either end of the shade roller and either side up, that is with the cam engaging either the top edge or bottom edge of the base plate. In this manner the length of adjustment or adaptability of the device would be increased.
Furthermore, it is within the scope of the invention to provide opposite cam edges, one to engage each of the bent over edges of the base plate. Such a construction is shown in Fig. 5 wherein the reference numeral 15 indicates an adjustable member comprising a slideplate 16 and a bracket arm 17. A locking member 18 is pivoted as at 19 upon said slide plate preferably midway between the top and bottom edges, said locking member or cam providing opposite cam edges 20, adapted, when the slide plate is slid onto the base plate, to underlie the opposite bent over edges thereof. A finger piece 21 is bent up from said locking member for the convenient manipulation of the same. In this construction I have shown both a slot 22 and a hole 23 in the bracket arm 17 whereby the arm may support either end of the shade, it being obviously within the scope of the invention to perforate the arm in any way best adapted to the use to which it is to be put.
Detail modifications may be made in manufacturing my improved shade bracket,
without departing from the spirit and scope of the invention, andI do not wish to be understood as restricting myself except as required by the following claims when construed in the light of the prior art.
Having thus described the invention, what I claim is: i
