DEVICE FOR FASTENING CABINET-HARDWARE,

, Application filed ugust 18,

To all whom it may concern:

Be it known that I, CHARLES S. BARNARD,

a citizen of the United States, residing at Bridgeport, county'of Fairiield, State of Conl neeticut, have invented a new and useful Device for Fastening Cabinet-Hardware, oli which the following is a specification.

I This invention relates to the securing of i cabLnet-hardivare-as, for example, pulls,

handles, &c.-to drawers and doors.

It is of course well understood that it is a I serious objection to the ordinary means of attaching articles of cabinet-hardware to drawers, doors, &o., that the bolts frequently 1 get loose and the fixtures drop oft. I am aware that various more or less complicated and ex ensive devices have been produced for locking the bolts in place. Many of them are not'eflicient for the purpose desired, and most of them, so far as I om aware, are so complicated and expensive to manufacture as to add greatly to the cost of production and prevent their going into general use. In order to overcome these objections, I have devised a securing-plate adapted to be used on the inner sides of drawers, doors, &c., to lock the bolts by which the fixtures are secured in place against rotation, so that when once atunder all the ordinary conditions of use, such as the opening and. closing of drawers, and doors and for any length of time.

My present invention consists simply in a plate struck out from sheet metal and formed complete at a single operation, said plate being rovided with a socket to receive a bolthea and on its under side with spurs or lugs which engage the woodwork of a draweror d orand lock the bolt, by which a fixture is secured in place against rotation.

In the accompanying drawings, forming a part of this specification, Figures 1 and 2 are plan views of retaining-plates provided with different forms 0 polygonal sockets to re ceive (litferently-shaped bol t-heads Fig. 3, an elevation of a bolt with the retaining-plate and woodwork in section, illustrating the locking of the plate and bolt against rotation by the engagement of spurs on the plate with the woodwork; Fig. 4, a section of areview, and Fig. 6 a plan view, of a slightly-variant form of retaining-plate detached.

10 denotes a bolt having a olygonal head 11, and 1? woodwork with w rich the boltis engaged.

l3 denotes my novel retaining-piate which is blanked out aui formed complete at a single operation from sheet metal. At the center of the retaining-plate is an opening 14, through which the bolt passes, and surrounding the opening is a polygonal recess 15, which is made of a shape to correspond with the head of the bolt that is to be retained in place. The recess is formed sinmltancously with the blanking-out operation by depressing the metal at the center of the plate.

16 denotes lugs or spurs which are struck out from the metal of theplate outside of the recess, one side'of ear-h spur remaining attached to the piate. I

'In the form illustrated in Figs. 5 and 6 the lugs are struck out at the edge oithe plate instead of intermediate the edge and the recess, as in the other form.

in use the bolt is passed through the centraiopening in the retaining-plate, the head of the bolt lying in the recess, and then the bolt is passed through the woodwork and turned mto the fixture, or else the bolt is held stationary and the fixture is turned thereon. In practice there is suliicient spring to the metal of the retaining-plate to permit the plate to be rotated with the bolt, if necessary, the spurs dragging over the surface ofxthe woodwork. As soon as'the bolt is set to place, however, the spurs engage the i mallet to set'the spurs firmly into the Woodwork.

It ill be observed that the wall of the opening 1 is continuous or unbroken, and

' the same is true of the margin of the recess 15, the spurs 16 being located between said margin and the ed e of the plate and not communicating with either the recess or the opening. Therefore the plate is practically not weakened in any way by the punching out ofthe spurs, for the continuity of the plate around the recess and opening is uninterrupted. I am therefore able to provide a device of the character described which, although of sheet metal and capable of being leave the continuity thereof uninterrupted.

formed by the single stroke of a punch or I die, is practically as strong and effective as a much heavier and more expensive device worked out by several operations.

Having thus described my invention, I claim A deviceof the character described comprising a sheet-metal plate uniform in thick ness at all points of its area and having a central opening 10 receive a bolt, and formed "with a polygonal re ess in one face surrounding the opening and having integral spurs projecting from the opposite face for the purpose describerl, the wall of the opening and i the margin of the recess being continuous or unbroken, and the spurs being located outside the margin ol the recess and opening to l 2. The combination with a bolt having a i polygonal head, of a sheet-metal plate uniform in thickness at all points of its area and having a central opening to receive the bolt, and formed with a polygonal recess in one 1 face surrounding the opening and having integral spurs projecting from the opposite face for the purpose described, the Wall of the opening and the margin of the recess being continuous or unbroken, and the spurs being located outside the margin of the recess and opening to leave the contlnuit-y thereof uninterrupted.

In testimony whereof I allix mysignature in presence of two witnesses.
