DEVICE FOR SECURING COVERS TO FRAMES.
SPECIFICATION forming part of Letters Patent No. &67,98 0, dated February 2, 1892.
Application filed July 9, 1890. Serial No. 358,153. (No model.)
To all whom it may concern.-
Be it known that I, HENRY LEVY, of New York city, in the county and State of New York, have invented a new and useful Improvement in Devices for Securing Covers to Frames, of which the followingis afulhclear, and exact description.
My invention relates to devices for securing covers to frames, and has for its object to provide a means wherehyacoveras netting, for example inay be expeditiously, conveniently, and neatly applied to a frame and removed therefrom without danger of chipping, scratching, or otherwise marring its appearance.
A further object of the invention is to so construct the devices that they will be exceedingly economic, light, and adjustable to frames of all sizes.
The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.
Reference is to be had to the accompanying; drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the Figure 1 is aperspective view of one corner of a picture-frame, viewed from the front and illustratingthe application of the devices. Fig. 2 is a perspective view of a corner of a frame, viewed from the rear and illustrating the application of a modified form of the invention. Fig. 3 is a perspective View of the rear clamping-plate illustrated in position in Fig. 1. Fig. 4 is an edge view of the said clamping-plate. Fig. 5 is an edge view of the front tie-plate in position, a portion of the glass and a portion of the frame being shown in section. Fig. 6 is a plan view of the rear clamping-plate illustrated in position in Fig. 2, and Fig. 7 illustrates two such plates attached to the respective ends of a piece of tape.
The prime object of the invention is to provide devices which will of themselves effectually retain a protective fabric or covering in position upon a frame, and to provide for the expeditious adjustment of the devices to frames of different depths.
In the construction illustrated in Fig. 1 the device consists of a clamping plate A, a tieplate B, and a connecting cord or tape D. \Vhen the clamping-plate is to be applied to the corner of a frame, it is constructed with two members 10 and 11, one at an angle to the other, as shown in Fig. 3, and each member at its side edge hasformed thereon a flange 12. In the flange of each member, preferably near the outer edge, a tapering slot 13 and an adjoining aperture 14 are produced. When a clamping-plate is designed for engagement with the side of the frame, its contour varies from that above describedas, for instance, the plate may consist of a single flanged member, and the slot and aperture are located nearer the center than the ends of the flange.
The tie-plate B, when adapted for use in a corner, consists of an essentially-triangular body 15, having side flanges 16,the longitudinal edges of which flanges are offset to form lips 17, extending outward in a plane parallel with the body, and near the apex of the body a tongue 18 is constructed; or a hook or a stud or the equivalents thereof may be substituted, if desired. If a tie-plate is needed between the corners of the frame, it may be constructed to correspond to the contour of one side of the corner-plate. In this event the tongue may be located at any desired point between the ends of the plate.
The cord D employed is preferably an elastic cord, and the devices above described are applied in the following manner: A strip 19 of any desired material is placed upon the frame, the said strip being of suflicient width to extend from the front inner edge over the rear edge. A tie-plate B is located at each inner cornerof the frame, the flanges thereof engaging with the inner edges of the molding 20, as shown in Fig. 1, and by thus engaging the flanges the lips 17 of the plates are forced between the molding 20 and the glass 21, and carry with them the inner edge of the coverstrip, as represented in Fig. 5. The elastic cords D are passed over the tongues 18 of the tie-plates and the ends of the, cords are drawn rearward, one at each side of the corners of the frame, and passed outward through the apertures 14 of the clamping-plate A, and then down through the larger portion of the tapering slots 13. \Vhen the cords hzwe been properly adjusted, those portions passing through the slots 13 are drawn into the contracted ends of the slots, and by reason of the tapering walls are firmly held to place. The attachment of the devices is completed by carrying the clamping-plates to the back of the frame, thereby exerting tension upon the cords and seating said plates at the corners, as shown in Fig. 1, the flanges of the plates resting upon the sides and ends of the frame and their body portions bearing against the rear face of the frame.
The cover needs no other means of attach-- ment than the devices above described, as the front tie-plates effectually bind the inner edge of the cover to the frame and the rear clamping-plates firmly hold the rear edge .of the cover in position. The cords Dare placed under sufficient tension only to hold the connected tie and clamping-plates in position, and therefore the said cords do not in the least injure the corners of the frame over which they pass.
The modification shown in Fig. 2' diifers from the devices illustrated in Fig. 1 only in. the means for securing the elastic cords to the back of the frame. The clamping-plates A are substituted by plates constructed with but a single member, comprising a shank anda body-section. In the end of the shank an eye 22 is formed, and also an aperture corresponding to the aperture 14 in the angle-plate, and in the body the tapering slot 13 is produced, the reduced end of which slot extends into the shank, while the opposite end is wider than the corresponding portion of the slot in the angle-plate, as shown in Fig. 6. In connection with this form of clamping-plates hooks 23 or their equivalents are employed, which hooks are secured in any suitable or approved manner to the back of the frame. The hooks usually constitute extensions of keepers 24, which keepers are preferably of corresponding contour with the corner clamping-plates A, the keepers being screwed or otherwise attached to the back. As a. matter of convenience, said keepers are provided: with three hooks; but the number of hooks may be increased or decreased as oo- 'casion may demand.
Vhen two cords are employed at the corners of the frame, each end of each cord is passed through the aperture 14 of a clampingplate, and after proper adjustment the ends of'the cord are made to enter the contracted endsof the tapering slots 1'3',the operation of attachingthe plates to the frame being completed by hooking the plates to the keepers, one near each end of the latter, as shown in Fig. 2.
The elastic cord may be substituted bytapes D, also elastic, and illustrated in Fig. 7, in which event the modified form of clampingplates is employed,---one being located at each end of the tape, and a connection is effected between the clamping-plates and tapes by passing the ends of the latter through the eyes 22 of the plates and into engagement with the converging walls of the tapering slot. When tapes are substituted for the cords, but
' one tape is used at the corner of the frame,
the tapes being made to engage with the corner surfaces, and one clamping-plate of each tape is engaged by the tongue 18 of the front tie-plate and the other clamping-plate is carried to an engagement with the central hook of the keeper.
Having thus described my invention, I claim. as new and desire to secure by Letters Patent- 1. A picture-frame clamp consisting of a member for engagingthe outer side of a frame, a member for engaging the inner front side of the frame, and an intervening portion connected to said members and constructed to retain them in engagement with the frame.
2. The combination, with a tie-plate adapted to secure one edge of a cover to the inner edge of a frame and. a cord attached to the tie-plate, of a clamping-plate provided with an aperture and an adjacent tapering slot to receive and bind the free end of the cord, which clamping-plate is adapted for attachment to the rear of the frame, substantially as and for the purpose specified.
3. In a device of the character described, the combination, with a tie-plate provided with marginal lips adapted to enter between the molding of'the frame and its glass, of a clamping-plate provided with an aperture and an adjacent tapering-slot, the said clamping,- plate being adapted for attachment at the back of the frame, and an elastic connection between the tieplate and clampingplate, substantially as shown and described.
4. As an improved article of manufacture, a tie-plate for frame-covers, provided'with a marginal lip located at an angle to the body, and a tongue upon the face of the body, substantially as and. for the purpose specified.
5; As an improved article of manufacture, a clamping-plate adapted. for engagement with the back of a frame, the said platebcing angular in cross section and provided with a tapering-slot, and an aperture adjacent tothe slot, as and for the purpose set forth.
