be obvious and in part hereinafter pointed out.

Theinvention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which willy be exemplified in the construction hereinafter described, and of which the scope of application will be indicatedin the following claims.

In the accompanying drawing, in which. is shown one of the various possible illustrative embodiments of this invention, c

Fig. 1 is ali-inside elevational view of a refrigerator wall and a refrigerator door provided With a door closing device embodying the invention; c

Fig. 2 is a cross-sectional View` taken on line 2-2 of Fig.`1; c

' Fig. 3 is a cross-sectional view taken on line 3-3 of Fig. 1.;

` Fig. 4 is a view similar to Fig. 1 but showing the door in open position; and

Fig. 5 is a cross-sectional view taken on line 5-5 of Fig. 4. f

`Referring now in detail to the drawing, 10 designates a refrigerator wall havinga door opening 11 for the door 12 which is hinged to said wallon hinges 13, and is adaptedv to be o cned outwardly by the latch mechanism 14. T e door 12 is provided withV a door closing device 15 embodying the invention.

Said closing device 15 comprises a bracket 16 attached to the inner side A17 of the door, in any suitable manner, as for example, by screws 18, said bracket 16 being provided with abearing opening 20. Pivoted to said Y 5G bracket 16 is a socket member 21 having a pin 22 ournaled in said bearing 20, and a head 23 contacting the rear of the bracket16. The member 21`is further formed with'a Wall 24 providedwith an axial through opening 25 s and with a cylindrical socket portion 26. f

` said tubular member to said socket.

The wall 24 thus forms an end wall for the tubular member 29; Slidably "extending through said axial opening 25 is a screw threaded member 31 to the outer end of which is attached a knob 32 for turning of said screw 65 threaded member. Screwed tothe opposite end of themember 31 is a member 33 of any suitable construction having bifurcated ends 34 interconnectedby a transverse pin 35.

Partially housed in the tubular member 29 70 is an-elongated tension spring 36anchored at .its linner end to lthe member 33 by means of an integral eyelet portion 37 received between the bifurcated members 34 and around pin 35. The `engagement of said eyelet portion 37 in the slot between the bifurcated members 34 prevents member 33 from turning within the tubular member 29. At `the upper end thereofs ring36 isv provided 'with another prefer. ly integral eyelet portion 38 80 extending through a ring 39. Attached to said ring 39 is a hanger member 41'preferably made of a singleA elongated piece of spring wire, having upwardly andoutwardly diverging

armr Vportions

42 and 43 intercon- 85 nected by akcoiled portion 44 received within said ringr 39. The upper end 46 of the arm 43 may be in the form of a hook'and is attached to an eyelet or the like fastening member 47 fixed to the inner wall 1() adjacent the 90 door. The upper end ofrthe arm 42 is likewisepreferably in the form of a hook 49 which'engages an eyelet or the like attaching member 50 fixed to the inner face 17 of the door 12. The attaching members and 50 95 closed, the spring 36 is preferably under 100 tension for normally retaining the door in closed position. Upon opening the door, by reason of the increase in linear distance between the attaching

members

47 and 50, the spring 36 will be further tensioned so that upon releasing the door from any open position thereof, the door will be swung back to closed position. By means of the handle 32 the tension spring 36 may be adjusted. Obviously upon turning the handle in such direction as to pull the member 33 downwardly, the tension on the spring will be increased.

AIn securing the device 15 to the door 12 and wall 10, the brackets 16 is preferably first attached to a suitable portion of the door. The attaching members 47 and 5() are then fixed to the wall and door, respectively, in such position that the

arms

42 and 43 must be forced apart and the spring 36 must be pulled or stretched several inches beyond the outer end of the tube 29 to cause engagement between the

hooks

46 and 49 and the

eyelets

47 and 50, respectively. The door will then be retained in closed position by the spring. The tube 29 serves to house and protect the spring and the usting members, and obviates danger oi injury from contact with said members, while at the same time making for neatness in appearance.

By reason of the pivotal connection between the member 21 and the bracket 16, the tube 29 together with said member 21 may pivot about the bracket as the door is opened or closed. The tension produced by forcing the

arms

42 and 43 apart before engaging the upper ends thereof with the

eyelets

47 and 50 aids in normally urging the door to closed position. As will be readily understood, the tension of the spring 36 causes a downward pull on the ring 39 and coil portion 44 of the member 41, which pull is in turn transmissable along the

arms

42 and 43, so that components of these pulls act at the connection between the upper ends of said arms and the

members

49 and 50, to retain the Vdoor in closed position or return the door to closed position after the door is opened.

Although the device 15 is shown herein as applied tov a refrigerator door, it will be clearly understood that my improved device may' be attached to any suitable door or closure member, the upper end of the arm 43 being attached to the door amb. As shown in the drawing, the inner surface of the wall 10 is substantially flush with the inner surface 17 of the door 12. It is obvious, however, that where a device is applied to a door and door jamb. which is offset from the inner surface of the door, the eyelet 47 may be attached to the inner surface of the door jamb.'

Upon opening or closing the door, the tubular member 24 mayswing about the pin portion 22 which is journaled in the bracket 16. The device 15.1nay be attached to the outside of the door for normally opening the door; In such case, the bracket 16 would be attached to the outer side of the door and the

members

47 and 50 would be attached to the outer surface of the door 12, respectively. Upon releasing the latch 14, the spring 36 would, in such case, canse a downward pull on the

arms

42 and 43 which would cause the door to open automatically.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made in the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
