Specification of Letters Patent.

Patented Jan. v, 191e.

Application led November 4, 1916. Serial No. 129,457.

To all twhom t may concern:

Be it known that I, JOHN R. MITCIIELL, a citizen of the United States, resldlng at hicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Refrigerator-Door Fasteners, of which the following is a full,

clear, concise, and exact description, reference being hadto the accompanying drawi s, forming a part of this specification.

y inventlon relates to improvements 1n refrigerator door fasteners.

@ne of the objects of my invention 1s to provide a door fastener adapted to both open and close refrigerator doors and one which may be operated from eitherside of the door. v

Another object is to provide an efficient -reigerator door fastener. l

. ln the drawings formlng a part'of tins specication, Figure 1 is an elevation of a refrigerator door showing the outer part of my improved door fastener mounted thereon. 4 Fig. 2 is an enlarged detail showin a section taken on line 2-2 of Flg. 1 andA urther illustrating the inner-mechanism of the 1m. proved door fastener. y A

Fig. 3 is a vertical section, taken on line e-.a of Fig. a.

Fig. 4 is an enlarged detail, showlng tho bearing end of one of the operating levers.

Fig. 5 is an enlarged section, talgen through one of the operating levers at line 5-5 of Fig. 2.

Referring' to the drawings, the numeral 6 indicates a door, 7 a door frame comprising the lintel 8, the osts 9--9 and the threshold 10, all of whic for convenience, may be termed the frame surrounding the door.

y improved door fastener indicated as a whole by the numeral 11, it will be obvious, may be mounted either upon the door or upon the frame surroundmg the same. In the form of my invention illustrated 1n the drawings, the fastener is shown mounted upon the door Gand comprises an outer operating lever 12, an inner operating lever 13, a shaft 14, bearings 15-15 therefor, an inner plate 16 and an outer plate 17..

'lhe outer lever 12 and inner lever 13 are substantially counterparts and therefore 1t will be necessary to describe only one. Each lever consists of an operating handle 18 at one end and a bearing arm 19 at its other end and is providedfwith a perforation 20 for the passage of the shaft 14, the said shaft being provlded at lts ends with a nut 21 and an adjacent washer 22. Thebearings 15 for the shaft comprise a sleeve 23 surrounding the, annular rib 24 on the bearing of the lever. The bearing arm of the lever is provided with a recess 25 within which is mounted a protruding roller 26 the said roller hav- -ing a shaft 27 journaled at its ends inthe perforations 28 and 29 provided in the bearing arm therefor.

' The frame surrounding the door, as for instance, the .door post 9 is provided on its inner face with a recess 30 within which is mounted one end of the inner bearing plate 31, the 'said bearing plate extendin outwardly as indicated at the .numeral 32 1n Fig. 3 `of the drawings and being secured at its ends to the'postsby suitable means, as for instance, the screws 33. The outer bearing v plate 17 is mounted on the outer face of the post 9 substantially opposite the inner bear# ing 4plate 16 and has an outwardl extended bearlng face 34 which is extends in the inwardly-turned portion 35 as illustrated in Fig. 3. The outer bearing plate is secured to `the post 9 by suitable means, as for instance,

the screws 36--36. The bearlng faces of the outer and inner'bearing plates are substantially parallel throughout.

When th illustrated by .pulling theA lever 18 downwardly until it assumes substantially the position indicated by the dotted lines indicated at the numeral 37 in Fig.- 1 of the drawings. As the lever moves downwardly, the bearing arm thereof Vmoves upwardly, the roller 26 traveling upwardly and outwardly on the lbearing plate 34, thus forclng the door open. During this movement the inner 'bearing arm is moving upwardly and substantially parallel in its travel to the outward movement of the outer bearing arm.

When the roller of the outer bearing arm has reached the position indicated by the dotted lines indicated at the numeral 38 in Fig. 3 of the drawings, the roller of the Vinner bearing arm will be substantially at n. mman, on

e door is in closed position, asi in Fig. l, the same may be opened vosi ' same in the operation of thel levers.

. To close the door from the outside, the outer lever is moved from the position shown by the dotted lines indicated at the numeral 37 in Fig. 1 of the drawings in a contraclockwisel direction, thus likewise rotating the inner lever and through the action of the bearing arm thereof upon the inner bearing plate, forcing the door to its closed position.

It will be understood that the shaft 14 is squared or similarly conformed at its ends 40 to prevent the rotation of the levers u on the shaft and to transmit the forceapplied to the lever on one side of the door to the lever upon the other side of the door. When inside the door, in a similar manner the door may be opened or closed through the operation of the inner lever 13.

It is thus apparent that by the use of my invention, one can enter a refri erator` and when within the same can tight y close the door thereof to prevent the escape of the cold air or the inrush of the warmer, out-v side air; likewise can open the door from the inside as well as the outside thereof.

What I claim isV 1. In a device of the character described, the combination with a pivoted door and a door frame, of cam bearing plates secured to the opposite sides of the door' frame adjacent the freefedg'e of the door when the latter is in closed position, said cam plates having their bearing surfaces oppositely ar. ranged, a shaft extending through the door near .its free edge, operating levers copera- .ble with said shaft on the inner and outer faces of the door, each of said levers having a bearing larm adapted to coperate with one of said cam bearing plates, one plate and one lever coperating to pull the door to closed position and the other lever and plate coperating to force/the door open.

2. In a device of the character described,

the combination with a door and a frame adjacent the door, of .a shaft assing through one of said members and caring lates secured to the other of said memers, the shaft being provided with an inside andan outside lever each non-rotatably secured thereto, each of said levers having a bearing arm adapted to engage a bearing shaft being provided with an inside and an .outside lever each non-rotatably secured thereto, each of said levers having a bearin armadapted to engage a bearin plate, the bearing plates having substantia 1y parallel bearmg faces for said bearin arms, the

,bearing faces of said plates being angular to the member to which they are secured.

4. In a device of the character described, the combination with a door and a frame adjacent the same, of a shaft passing through one of the said members, yinner and outer bearing plates secured to the other of said members, a collar surrounding said shaft, a lever at each end of said shaft, the collar having enlarged washer-like ends to be engaged by the adjacent lever, the said levers aving bearing arms, each adapted to engage a bearing plate, thesaid bearing plates having substantially parallel bearin faces, said bearing faces being angular to t e normal path of tl-.c levers, y

In witness that-,I claim the foregoing .I have hereunto subscribed myvname this 30th dayof October, 1916.
