- vrlhe presenty invention relates to improvements in self-adjusting anti-rattle dovetails, particularly for automobile doors, an lobject being to provide a device of this character l socket member is vprovided as an attachment The present arrangement greatly simplifies assembly and provides a permanent, reliable and accurately positioned socket. It isl proposed in the present embodiment to provide a Vdovetail in which the socket member is'provided with laterally adjustable resiliently supported dovetail members adapted to have a Ywedge member engaged between them, the respective dovetail members being supported against Vertical movement, and which are adapted to retain the door against vertical vibration,and compensate for wear,llateral movement,-and variations in thevertical and lateral lalignment of the door.

A y A. still further obj ect is to provide a device in which the'dovetaill members will be protected from eXcessivewear and breakage, and may be made of a self-lubricating substance, such as fibre, bakelite or the like, to the end that the device will have a long life', and the necessity for lubricating the same'will be the door showing the wedge member mounted thereon, the door being shown' in `dotted e jlines,"while the wedge-membeIi-is shownn full lines.

Referring to the drawing, the device, according to the present embodiment ofl'theinventon, comprises a ,socket element incorpon rated as a Astructural part` of the metal post of the door frame 10, and a wedge element adapted to be secured to the edgeof the door vthe socket upon closing of the door. y K The metal post 10 ofthe'door frame is bentl along a vertical line to forma right angular corner, against which the door closes. A

lrearwardly converging opening 12 is cut posed iny parallel vrelation and its end; edge vertically disposed.

' The inner or box part .ofA the' sock-et'V is i formed from sheet metal and as shown in Fig. 5 comprises a rectangular portion 13 having wall flanges 14, bent from its upper and lower and rear edges, and outwardly extending base lianges l5 bent from the upper,` and lower wall flanges. A pair of inwardly bent llugs 16 rare struckfrom the rear wall 'flange for supporting the ends of the springs, presently to beV more fully referred to.

socket as- The box thus provided is somewhat wider than the opening 12 and upon its forward edge there is provided a projecting lip 17 of such dimensions as to enter the opening 12 to seat upon its vertical edge, and to project slightly beyond it, lthe projecting portion being bent at a slight angle. When so engaged the base flanges lie flat upon lthe inner surface of the post, their forward edges abutting the inner surface of the flange of the post, and in this relation the box is secured by spot-welding the base flanges to the post at suitable points, as indicated at 18, Fig. 8.

It will be seen that the lip, with its angularly bent edge accurately positions the box upon the post so that it may be secured in its proper relation with the greatest facility, and in the assembled relation prevents distortion ofthe box through strains imposed upon it. The lip has the further advantage of forming a guide surface for the Wedge element as it enters the socket.

A pair of opposed block members 19 of generally rectangular shape are disposed within the casing, these blocks `having flat parallel surfaces 20 adjacent the inner ends in-sliding'engagement with each other, and cooperating with the upper and lower parallel 1walls of the casing to prevent ver- Atical displacement of the blocks. Inclined slightlyy arcuate faces 21 extend from the flat faces 2O to the forward ends of the blocks in diverging relation to each other. Pockets 22 are provided in the rear walls of the blocksv within which are engaged coil springs 23 positioned upon the lugs 16 of the casing, and which press the blocks forwardly against the flange of the post, as shown in Fig. 6, while permitting the blocks to be forced laterally inwardly as shown in Fig. 10. In both positions the inclined faces 21 are projectedy into the opening. 12. l Y

p The blocks may be assembled within the casing through the opening 12, this being done conveniently by first inserting one of the blocks and its spring, and then inserting the other block and its spring,rpressing the first block inwardly while the second block is being inserted. The blocks may be of any suitable material, and because of the protection against breakage afforded by the casing, may be of fibre, bakelite, or other suitable squeak preventing, self-lubricating material.

`The wedge member comprised an attaching base 24 having screw holes 25, and a rigid projecting -wedge-shaped projection 26, having flat inclined sides 27, substantially corresponding to the inclination of the dovetail blocks. Y

The slightly arcuate shape of the inclined surfaces of the blocks permits firm engagement of the wedge member irrespective of Y slight variations in the vertical alignment of the door. Obviously thisarrangement may be reversed, if desired, and-the inclinedsur-V faces of the Wedge member made slightly arcuate, the inclined surfaces of the blocks being flat.

In Figs. 12 and 13 we have shown a modification in which the block members 19 are adapted to be assembled and held in the box casing before the latter is attached to the post. For this purpose lugs 28 are formed upon the forward edges of the upper and lower wall flanges 14, being bent inwardly so that their forward surfaces are flush with saidforwardedges of the wall. In the forward ends vof the block members there are provided .pockets 29, of corresponding depth to the metal thickness of the lugs, and within which the latter engage with kthe forward end surfaces of the blocks in flush relation to the forward edges of the box, `so that the same may be assembled against the flange of the post in exactly the samemanner as the box illustrated in Fig. 5. The engagement of the lugs 28 in the pockets 29 not only retains the blocks against the outward pressure of the springs, but so interlock with the pockets as to prevent displacement through the open side of the box, thus permitting the box with the assembled blocks to be handled and shipped in quantities without danger of the blocks becoming displaced.

The operation is as follows When the door is in open position the blocks are projected forwardly against the flange of the post as indicated in Figs. 1 and 6.V vAs the door is closed the wedge member engages betweenjthe blocks, contacting therewith before the door is completely closed, the complete closure of the door causing the blocks to be moved laterally against the pressure of -the springs which yhold the blocks snugly against the wedge member, while the inclination of the `engaging surfaces is such that vertical pressure will not displace the blocks and cause vibration.

The door is provided with the usual latch not shown, which engages behind a striker on the door frame, and the-present device is such that it permits the door to close sufliciently to allow the latch to operate, and thereupon jexerts an outward pressure on the door to force the latch bolt tightly against nthe striker. Upon release of thelatch the device exerts an opening pressure on the door. f V

Should the wedge member be out of alignment with the socket, due to sagging of the door or inaccurate mounting of the wedge member, the independent movement of the respective blocks will permit them to adjust themselvesto the wedge surfaces and perform their' cooperative retaining function.

We haveillustrated and described a pre- 'ferred and satisfactory embodimentof the invention, but 4it will be obvious that changes may be made therein,`within the spirit and 1 -Y scope thereof, as deiined in the appended claims.

Having thus described our invention what We claim and desire to secure by Letters Patent is l. In an anti-rattle device for doors, the combination with a door frame metal post forming an angular corner and having a Wedge receiving opening, of a casing adapted to be engaged at the inner side of said post and having a projecting lip portion adapted to engage in said opening to accurately position said casing with respect thereto, Wedge engaging means disposed in said casing, and a Wed Ue member adapted to be engaged there- With through said opening and to be guided by said projecting lip. p
