Description

Patented Oct. 13, 1936 i UNITED STATES PATENT OFFICE ANTIRATTLE DOVETAIL FOR DOORS Thomas T. Logic, Bridgeport, and Arthur Claud- Mantle, Trumbull, Conn., assignors to The Bassick Company, Bridgeport, Conn., a corporation of Connecticut Application March 21,

5 Claims a wedge member engaged between them, the respective block members being supported against vertical movement, whereby the rattle usually resulting from vibration and weaving of the door is prevented and the door is effectually retained against vertical movement, while at the same time lateral movement and Wear is compensated for.

It is an object of the present invention to provide improved means for slidably retaining the lock membersin the casing, whereby accidental displacement is prevented, and at the same time assembly, and removal of the blocks for replacement purposes, is facilitated. Another object is to provide block members which will more accurately fit in the casing, and to this end we propose to provide means for compensating "-for' slight variations in the dimensions of casing- A further object is to provide a block member formed of sheet metal, and which will be of hollow formation opened atthe back to provide a socket for receiving and retaining the end of the pressure spring. 7 V 1 With the above and other objects in view an embodiment of the invention is shown in the accompanying drawing, and this embodiment will be hereinafter more fully described with reference-thereto,--and the invention will be finally pointed out in the claims.

spending parts throughout the several figures of the drawing. Referring to the drawing the anti-rattle dovetail device, according to'the'exemplary illustrated embodiment of our invention, comprises generally a socket member, adapted to be secured to the door frame within a suitable recess, and a wedge member, adapted to be secured to the edge of the door in relation to enter the socket member upon closing of the door.

The casing of the socket member comprises an outer part consisting of a face plate member l0, preferably formed of sheet metal, having aflange l i at its forward edge bent at a right angle, and a lip 12 bent forwardly from the flange'l l. A rearwardly converging opening I3 is provided in the face plate and extends across the flange I l to the lip I2, the forward portion of the opening having its upper and lower edges disposed in parallel'relation. Counter sunk screw holes H are provided in the face plate near the upper and lower edges for attachment of a socket member by screws to the door frame. l The inner or box'part of the socket member is also formed of sheet metal, and, as shown in Figs. 4 and 5, comprises a rectangular portion [5 having side wall flanges l6l 6 bent from its upperandlower edges and a rear wall flange! 1 bent from its rear edge. The flanges |6l6 have attaching ears l8l 8 bent outwardly therefrom, and which are adapted to be secured to the face plate by spot-welding or other suitable means.

A pair of inwardly bent lugs l9-l9 are struck from the rear wall flange ll for supporting the ends of the pressure springs, as will hereinafter more fullyappear, and upon the forward edges of the sidewall flanges I 6-46 there are provided projecting lugs 2020, narrower than the side flanges and disposed intermediate their upper and lower edges, these lugs being bent rear-- wardly into spaced, and parallel relation with the inner surfaces of the side walls.

A forwardly projecting lipt2l is provided at the forward edge of the portion I5 and is curved slightly to bring its edge into'aligmnent with the lip l2 and to provide a guide surface for the wedge, as will hereinafter more fully appear.

A pair of opposed block members are provided in the casing, these being of sheet metal, pressed and bent to shape. clined' slightly arcuate face portion 22, side wall portions 2323 bent from the side edges of the face portion in spaced and parallel relation to They each comprise an in- 5 each other, a front wall portion .24 bent from the forward edge'of the face portion'in abutting relations, and a base wall portion 25 bent rearwardly from the front wall portion 24 about the rounded.

forward corner edges 26-26 of the side wall portions against the base edges of said side wall portions. An inwardly bent lug 21 is struck from the base portion 25 to form'an abutment for the end of the pressure spring, presently'to be more fully referred to. An aperture 28 for receiving the lug 20 is provided in the front wall portion 24 f V tightly against the striker. Upon release of the its lower edge being cut into the base portion 25;

In the assembled relation of the blocks in the socket member the lugs 2020 are engaged in the apertures 28-2B of the blocks, the 'sur-faces 25- 25 being in parallel relation-to each other and in sliding engagement with the side walls Iii-l6.

The blocks contact each other at their inner wide ends. The pressure springs 29r-2r9l'are engaged" at one end upon the lugs [9-4 9 and press against. the rear wall I1, and at their other ends are en aged; i itherbl elis ndipress' ain h lu s; 21--21, to force the blocks forwardly'against the Thelwe se memb r mprises a ta hin base i lhaving crew hol s-3 o at chme t er we' e oenend rieid p ec wed e-shape proie ti n 3. ha in inclined sides 33; substantially corresponding to the inclina o o th dove ail blo The slightly arcuate shape or} the inclined sur ace o he; b c p rmi s nn e eme of flthewedse; member r espec ve i s h variaw riens i he ver ca alignment f t oo Obvi I Qus this-arr ng mentmey be r d, if sired, ancl the inclined surfaces of the wedge m m er made s ig t er the i lin d surfaces o f the blocks being flat.
