application filed June 25, 1925.

This application relates to a door retainer of the type wherein a lug carried by the door of an automobile is engaged between and held by metallic strips or guards which cover the adjacent opposed surfaces oi two blocks of rubber or other resilient material. lifty improved construction embodies some of the features discussed in and covered by my 'copending application tor door retainer, der. No. 635,065, filed April 27, 1923..

Una of the objects of the present invention is to provide an improved means for holding the resilient blocks forming a part of the retainer, together with improved details of the said blocks. A further object of the invention is to provide means for se curing the door retainer in place on the door frame or post. Still further objects of the invention will be apparent from the following specification and claims.

In the accompanying drawing I have shown different embodiments of the invention but it will be understood that the drawing isfor illustrative purposes only and that various changes and further substitutions may be made within the scope of the claims without departing from the spirit of the invention.

Of the drawing:

Fig. 1 is an elevational view, partly in section, of a part of a door frame carrying a door retainer embodying the invention.

Fig. 2 is an edge view of the parts shown in Fig. 1, this view being partly in sectlon along the line 2'-2 of Fig. 1.

Fig. 3 is a sectional view taken along the line 33 of Fig. 1..

Figs. 4 and 5 are elevational and edge views respectively of the retaining lug adapted to be secured to the door.

idig. 6 is a detail perspective view shovving an alternate construction for the resilient block elements.

Fig. 7 is a detail perspective yiew showing another alternate constructlon of the blocks and guards.

Figs, 8, 9 and 10 are views similar respectively to Figs. 1, 2 and 3 but SllOW1I1 g' an alternate form of the invention, ldlg. 9 1S partly in section along the line 9-9 of Fig. 8, and Fig. 10 is in section along the line Zin -l0 of Fig. 8.

lteterring particularly to. Figs. 1, 2 and 3 at the drawing, 1 and 2 represent respec- .tively two opposed blocks formed 0t rubber fieriel Etc. Elttdflt.

or other suitable resilient material. lhe blocks may be formed separately or as parts a single unitary block member. In Fig. 1, l have shown them as being separate, but in either case they are spaced apart and are so shaped and proportioned as to be adapted to be. located in a recess formed in a'door frame orpost. The door frame may be of either wood or metal. Preferably the corners of the bloclrs are rounded at 3-3 so that the corners of the recess can be similarly rounded. When the door trams is formed of wood the rounding ot' the corners of the recess is an important factor as this permits the recess to be much more cheaply machined. With a steel door frame the recess can be pressed inward and shaped as required.

Carried by the blocks 1 and 2 are two guards 4 and 5 respectively engaging the ad jacent opposed surfaces of the blocks. These guards are preferably so supported by the blocks that their ends are out of contact with any other part of the door retainer or other structure, so that they are free to move upward, or downward, or laterally in directions parallel to the face of the door frame as permitted by the resiliency of the blocks. It will be understood that aretaining lug carried by the door, and hereinafter described, is adapted to enter between the guards l and 5. The door is thus guided into proper position and the construction de-' scribed permits the guards to be bodily moved by the retaining lug vertically or laterally when the car is being driven over rough roads, thus eliminating all rattles, squeaks and other unnecessary noises. Preterably in addition to moving vertically or laterally as described, the guards-are made narrower than the blocks, as clearly shown in Fig. 2, so that they are also movable to a slight extent transversely. This feature is also of considerable advantage in eliminating noises.

There can be variation in the details of the guards 4: and 5, but I ordinaril refer to make them as parts of a sin 1e -s aped member which fits between the locks 1 and 2. This U-shaped guard member lies in and fits the space 6 between the blocks 1 and 2. The U-shaped member is bowed out at 7 to fit a corresponding enlargement of the notch 6 and the ends oi the member are flared at 88. The ill-shaped member is thus held by the block member against endwise movements and it will be observed that the bowed section 7 and the flared ends 88 are entirely disengaged from any parts of the retainer other than said block member. I

A plate 9is provided which is adapted to entirely cover the blocks and the guards and also to entirely cover and close the recess in the frame. The plate is large enough to extend somewhat beyond the ed es of the recess soas to provide a good fimsh. Preferably this plate is flanged over at 10 and 11 to conform to the contour of the door frame. It is provided with an opening 12 which permits the retaining lug to enter between the resilient blocks and the guards.

In accordance with my invention I provide holes in the resilient blocks 1 and 2 into which extend suitable means for holding the said blocks and the said plate 9 against relative-bodily movement in directions parallel to the plane of the plate. As to the details of these holdin means, there can be variation but I preIer to so form the holding means that they will not only prevent relative bodily movement in directions parallel to the plane of the plate, but will also serve to permanently secure the block elements to the plate; In Figs. 1 to 3 I have. shown rivets 13 which extend through holes in the plate and also through holes in the block elements, these rivets being flanged over at iris-14 so as to secure the block elements in place. Preferably I also utilize the rivets 13--13 as .a means for holding the entire retainer in place on the .door frame. I To this end the said rivets are made hollow in the form of bushings so that retaining screws 15 can extend through these bushings into the material of the .door frame. It

will be noted that the rivets or bushings 13-13 abut against the bottom of the recess,thus serving to resist the pull of the screws and to prevent any tendenc for the resilient blocks to be compresse or deformed.

In Figs. 4 and 5 I have shown one type of retaining lug which may be used but it' will be understood that my present invention does not, articularly relate to the retaining lug and that the construction of this may be widely varied. As shown, this retaining lug comprises a single piece of sheet metal 16 which has the lug proper 17 formed integrally with it by stamping. Counterpunched screw holes are provided at 18 for securing the lug to the door. It will be understood that the lug is of such a size and is so located on the door that when the door is'shut the lug proper will enter between the guards at and 5 of the retaining means and slightly separate them so as to compress the blocks 1 and 2.

In Fig. 6 I have shown an alternate c0 struction, wherein the resilient blocks are formed as arts of a single unitary block member wh1ch is provided with a notch 19.- This notch divides the block member to form the aforesaid blocks 1 and 2", leaving a narrow connecting strip 20 between them.

In Fig. 7 I have shown an alternate construction of both the blocks and the guards. Two separate blocks,-such as 1", are provided, and also separate guards, such as 4". Each guard is curved inward and backward at its ends to engage similarly curved surfaces on the block. Each guard is thus directly secured to the corresponding block and has interlocking engagement therewith, and the block and the guard can be handled as a unit. It will be noted that in this construction the ends of each guard are so formed and located that, when assembled, they are out of contact with any other part of the 'door retainer or other structure.

r'eferablv also the guards are narrower than the blocks so as to have no contact at their edges with any other parts. This construction, therefore, has all of the advantages already set forth in connection with the construction first described.

In Figs. 8, 9 and 10 I have shown another alternate form of the invention wherein an enclosing box structure 21 is provided for the. resilient blocks. This box structure is shaped to conform to the outline of the blocks and the entire construction is such that this box structure can be added or omitted'without changing the construction or design'of any of the other parts of the device except the rivets 13-43. As shown this box structure21 is made of sheet metal and it is provided with holes adapted to register with the holes in the plate 9 and in the blocks. Rivets 13-13 extend through the holes in all three of these parts and are flanged over to hold them in fixed relation. It will be understood that these rivets are hollow as already described to receive the screws 15-45 which hold the entire door retainer in place.
