The approved form of construction comprises a base 6 which is rigidly mounted, by means of bolts or screws 7, upon the door 8 of a refrigerator. Projectingd upwardly from the member 6, adjacent one end thereof and spaced apart, are lugs 9 and 9. having registering openings therein.v A casing 10 is pivotally mounted at one end by means of a pin 11 which projects through the lugs 9 and 9. The casing 10 comprises a narrow, box-like structure in the form of a` channel which is'provided near its free end with a humped portion 12. The assage-way 13, which extends throughout the straight portion of the member 10, inclines upwardly and extends into the hum ed portion 12, as clearly seen in Fig. 2. rojecting downwardly from the member 10 and preferably made integrally therewith, is a finger 14 having a portion 15 which projects backwardly toward the pivoted end of the member 10, terminating in a plane which is parallel with the plane in which the inner upper surface of the member 10 lies, where the Specification of Letters Patent.

same extends upwardly in the humped portion 12. The member 14 is positioned centrally on the member 10, that is, projects downwardly from the member l0l in a plane which is equidistant from the side walls of the member 10. Projecting upwardly from the free end of the member 10 is an arcuate.4

handle 16 upon which is mounted a handhold 17. l

Projecting upwardly from the member 6,

and spaced apart, are lugs 18, which are provided with registering openings adjacent the upper end. A pin 19 is adapted to be positioned within the openings in the lugs 18. Positioned between the lugs 18, so as to lie upon the upper surface of the member 6 and engaging with its upper surface the pin 19, is a latch bolt 20 which is provided intermediate its ends with a slot 21 in which the member 14 is `adapted to engage when the same is in assembled. position, the ends of the slot 21 extending diagonally to the member 20, as at 22 and 23. rojecting up- Vwardly4 from the member 20, adjacent one end thereof, and spaced apart, are lugs 25 having registering openings therethrough, in whlch a pin 26 is adapted to be inserted for the prpose of rotatably mounting between said lugs a roller 27. The opposite end of the member 20 is bifurcated to form the members 28 having a registering opening therethrough. A roller 29 is mounted between the members 28 upon a pin 30 inserted in the openings in the members 28. The opposite end of the member 20 is provided with an interiorly threaded socket 31 in which is adapted to be threaded a rod 32. The rod 32 projects through an opening 33 formed in the pin 11 and is provided at its outer end with a square or octagonally shaped portion 32 by means of which the same ma be threaded into the butt-end of the mem` er 20. Positioned upon themember 22, intermediate the butt-end of the latch bolt 20 and the pin'll, is a spiral spring 34. Mounted upon the stationary portion 35 of the refrigerator by suitable fastening means, such as the bolt 36 and the screw 37, is a catch bar which is adapted to engage the latch bolt 20. This member. com-- prises a base 38, extending upwardly from which and preferably made integrally therewith, is a wall portion 39, the upper portion 40 of which inclines inwardly, having an outwardly inclined portion 41 which forms a striking plate for the latch bolt 20. Prof jecting upwardly from the base 38 at op osite sides of the member '39 and preferably made integrally with these parts, are wall portions 42.

The construction of the device is such that, upon an outward pull being exerted upon the member 17, the member 10 swings on the pivot pin 11 and thereby causes the roller 27 to move downwardly relatively to the base of the member 10. The roller 27 in its downward motion or during the upward movement of the `member 10 contacts with the inclined.l surface 22 of the portion 15 and thereby causes the arm 20 to move backward relatively to the member 11, thereby compressing the spiral spring 84. Upon the outward movement of the member 10, the latch bolt 20 is moved backwardly a suflicient distance'to afford a clearance between the bolt 20 and the catch member which is mounted upon the stationary part of the refrigerator. At the same time that the latch bolt 20 is moved backwardly relatively to the latch door which is mounted` upon the stationary part of the refrigerator, an outward pull is' exerted upon the door of the refrigerator. As the door swings outwardly at the same time that the bolt 20 moves backwardly, the roller 29 engages against the under surface of the inclined portion and is caused to rotate, thereby reducing the friction which is necessarily incident in the operation. As soon as the outward pull is released from the member 17, the spring 34 causes the member 10 to resume its normal position in which the latch bolt would be in operative or outwardly extending position. As shown,

the member 6 is provided with a slot 14 in which the member 14 operates. The door of the refrigerator is also provided with a slot 42 in which the inner end of the member 15 operates. In closing the refrigerator door, the roller 29 comes into contact with the striking plate 41 in which instance the arm 20 is moved backwardly in the latch socket or passageg 13, thereby causing the member 10 to swing outwardly on the pivot 11. As soon as the roller 29 has cleared the portion 41, the spring causes the member 2O to move forwardly again, the roller in this instance engaging the under surface of the portion 40. The forward thrust of the arm 2O by means of theA spring 34 causes the.

roller 20 to rotate on the member 40, thereby carrying the door of the refrigerator into a snugl closed position, the wall 39 finally affording a resistance to the forward thrust of the bolt. Mounted upon the interior of the door 8 is a plate 43, extending inwardly from one end of which'is a bushing 44 adapted to seat in an opening provided in the door 8, so as to communicate with the opening 42. Projecting upwardly from the lmember 43, adjacent the opposite end, are

spaced lugs 45, between which is pivotally mounted at one end upon a pin 46a lever or handle 47. The member 47 is provided intermediate its ends fwith a slot througth which a pin 48 projects so as to pivotally secure the member 47 between a pair of lugs 49 formed upon a rod 50 which projects into the opening 42. Formed in the opposite end of the member 50 is a threaded socket 51 in which is threaded a rod 52, the opposite end of which is curved to form a hook 54 which is adapted to project through an opening in the lower end of the member 14 and operatively connect the member 14 with the member 47. A vided to lock the member 54 in in the member 14. A

' The purpose of the handle and its operating parts which are mounted on the inner side of the refrigerator is to afford a means of opening the door from the interior of the the opening refrigerator. Upon pressing the outer or.

free end of the member 47 'inwardly toward the door 8, the memberl is moved outwardly so as to force the member 10 to swing outwardly from the door on its pivot 11, thereby retracting or withdrawingV the latch bolt 20.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of the construction set forth, but desire to avail myself of such Variations and modifications as come within the scope of the appended claims.
