SPEGIFIOATIONfQrming part of Letters Patent No. 735,618, dated August 4, 1903.
Application filed March 31, 1902.
To all whmn it ntcty concern:
Be it known that I, EDWARD TANNEWITZ, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented "certain new and useful Improvements in Furniture-Couplings, of which the following is a specification.
My invention relates to improvements in appliances for temporarily securing or uniting one portion of a wooden frame or case,
as the looking-glass frame, to the top of a bureau or other frame or case; and its object is to provide a fastening device with which the parts may be easily, readily, and conveniently connected and held 'firmly to place and as easily and quickly disconnected. I attain this object by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a front plan of my device. Fig. 2 is a longitudinal section of the same on the line 00 x of Fig. 1. Fig. 3 is a side view of the same attached to portions of a frame. Fig. 4; is a section of the same on the line 00% of Fig. 1. Fig. 5 is a back plan of the device,- and Fig. 6 is a plan of the slide in use. Without the plate.
Similar letters refer to similar parts throughout the several views.
A represents the base or back plate, that is designed to be secured to the under side of the bureau-top E as a foundation and support for the slide or wedge B. This base has preferablya right-angle projection a, that is designed to project back over the edge of the bureau-top E and avert the danger of the base being slid alongwith the Wedge when it is be ingdriven to place under the head of the bolt DD,'as hereinafter more fully described.
The base A has also guideways or guards ct and a" struck up from the surface for guiding the slide B and holding it to place when not confined by the strain of the bolt and has an aperture 0 for the passage of the bolt. This aperture should be of a proper size to allow the bolt to pass through freely, but closely. The slidejB has also a right-angle projection I), designed to lie parallel with the projection Ct, and is curved so that a flat in.- strument may be passed into the opening I) to start the slide back when desired to release the parts. It is provided also with a slot 0,
Serial No. 100,861- (No model.)
that is of a proper size to admit the neck (1 of the bolt. One end of this slot is enlarged, as at C, so that the head D of the bolt will pass through. The body of the slide adjacent this slot is offset to form the incline or wedge B, so formed that when the bolt has been passed through and the wedge is forced to the position indicated in Figs. 1 and 2 it will draw firmly upon the bolt and hold the end of the mirror-frame F firmly against the surface of the bureau-top E. This slide passes under the guides a and between the guides a, and is provided with a stop or guard I),
designed to come in contact with the ends of the guides and prevent the slide from dropping out of or away from the base when not in use.
The boltD DD must be securelyfastened into or to the mirror-frame F. In the drawing Fig. 4 I have shown it as secured by meansof a wood-screw D, and the body D and headD should be of a proper size to fit closely in the aperture e in the bureau-top E and the apertures C and O in the slide and plate, so
that it will tend greatly to strengthen the joint by reason of such close fit. Between the head and the bodyI form a small neck 01 of a proper size to allow the slot b in the slide and wedge to pass freely along under the head.
In the application of this device the several parts are assembled substantialy as indicated in Fig. 4: and the wedge driven to place, as
indicated in Fig. 3, in which position the dotted lines in Figs. 1 and 3 or as indicated c in Fig. 4.
The slide B may be used with very good results without the plate A; but I greatly prefer the use of the plate with the slide, as the working of the slide upon the wood is likely to wear the wood away in time to such an extent as to render the wedge inoperative,and, further, without the plate to securethe slide to the wood the slide is likely to be misplaced when not in actual use and be lost, and thus I00 cause great inconvenience and loss of time, while with the plate it is always in place. 1
When using the slide without the plate, I prefer that it be secured to the Wood E by means of screws 0 in slots 0 or with broad-headed brads, as 0 as indicated in Fig. 6, as by this means it is prevented from becoming disconnected from the wood and lost when the bolt is removed. v
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
The combination, with a bureau-top and a mirror-frame, of an apertured plate secured to the under side of the bureau-top, a bolt screw-threaded at one end and having an annular groove, forming a neck and a head, at the other end, and a slide movably held to said plate, said slide having a slotted wedge- EDWARD TANNEWITZ.
