HERMAN DANIEL SORG, OF PHILADELPHIA, PENNSYLVANIA.

MORTUARY REFRIGERATOR.

1,363,687. Specification Of Letters Patent. Patented Dec.-28, 1920.

Application filed October 19, 1917. Serial No. 197,515.

T o dll w horn it may concern:

Be it known that I, Herman Daniel Sorg, a citizen of the United States, residing at Philadelphia, county of Philadelphia, 5 and State of Pennsylvania, have invented a new and useful Improvement in Mortuary. Refrigerators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, 10 which form a part of this specification.

One of the main objects of the invention is to provide means whereby the sectional frame supporting the containing pan may be withdrawn from, and inserted within, its 15 cooling compartment from either end thereof, which capacity is of great value, and utility in mortuary refrigerators. Another object of the invention is to provide improved means for supporting the movable 20 frames in traveling relation one upon another and both upon the fixed frame. Another object of the invention is. to provide means for locking one movable frame to the other for part of their travel, and then auto25 matically unlocking the upper movable frame, and automatically locking the lower movable frame to the fixed frame, to permit the upper movable frame to move independently. Another object of the invention is 30 to provide improved means for supporting the pan upon the upper movable frame, in both the normal position of the pan and when manipulating it to facilitate removing the body.

A preferred embodiment of the invention is shown in the accompanying drawings, wherein·—

Figure 1 is a sectional view of a mortuary refrigerator embodying my invention.

Fig. 2 is a partial plan view of the containing pan.

Fig. 3 is a horizontal section showing my invention in plan, with parts omitted for clearance.

Fig. 4 is a sectional view of same on line 4—4 of Fig. 3.

Fig. 5 is a broken elevational view showing the working of the automatic latches.

Fig. 6 is an enlarged cross-section on line 50 6—6 of Fig. 4.

Fig. 7 is a detail side view of one end of the apparatus.

The refrigerator a shown in longitudinal section is of the known multiple unit type. 55 My invention, however, is applicable to a single unit. Each unit is open at opposite ends, which may be closed by doors b. Ex tending between the ends of each unit is the fixed frame, which consists of two channels c, these channels being about on a level with 60 the lower edges of the door-jambs (see Fig. 1) and about in line vertically with the upright edges of the door jambs (see Fig. 3). The cross-sectional shape of the channels, which is virtually that of a square, is clearly 65 shown in Fig. 6. A longitudinal opening d, the edges of which are turned downward, is provided in the upper face.

Within each channel is confined three pairs of rollers e, which are supported from 70 the downwardly depending angle bars f of the lower movable frame, which also comprises cross bars g, filling strips h and angle bars i, the latter supporting pairs of rollers 7i. The angle bars are secured to the cross 75 bars and,, between the cross bars, are spaced apart by the filling pieces.

The rollers k are confined within channels m, which are located directly above the channels c and are connected together by 80 rods n upon which are sleeved rollers o. The parts m, n and o comprise the upper movable frame.

Channels c and m are of the same size and construction, being merely inverted rela- 85 tively to each other. The angle bars f and i are of the same size and construction, the former extending downward, and the latter upward, from the cross bars g.

It will be understood, from the foregoing 90 description, that the lower movable frame is capable of rolling in a longitudinal direction upon the fixed frame, and that the upper movable frame is similarly capable of rolling upon and relatively to the lower 95 movable frame.

The containing pan p is adapted to rest and roll upon the rollers o and is provided with longitudinal rounded or beaded edges s which are adapted to slide upon longitu- 100 dinally extending angle bars r secured to the upper faces of the channels m. Either the rollers o or the horizontal wings of the angle bars r afford an adequate support for the pan. If desired, longitudinal strips y 105 may be secured to the under face of the pan, so that the strips j alone contact with the rollers o, stiffening the pan and thereby reducing the sliding friction between the pan and the rollers. . HO

In the lower of the three units shown in Fig. 1, both movable frames and also the containing pan are shown in position within the lower cooling compartment. To remove

1,363,687 the body from the compartment, either end 'door is opened and the movable frames may be moved into either of the two upper positions shown.

In withdrawing the frames to their fully extended position, the operator grasps the cross handle s on the outer end of the upper movable frame and pulls it to the fully extended position shown at the top of Fig. 1, 10 at which position its further movement is arrested. In the first half of the movement of ^:the upper movable frame, the lower movable frame is docked to and moves with it. At the (beginning of the latter half of the movement 15 of the upper movable frame, further movement of the lower movable frame is arrested •and the upper movable frame is unlocked from the lower movable frame and moves in•dependently. The means for latching and 20 unlatching the two movable frames and for arresting their movement, whether the movable frames are withdrawn from one end or the other of the cooling compartment, will now be described.

.Secured to each end of the upper movable frame is a pivoted latch t (see Figs. 5, 6 and •7) having a nearly vertical face t' which engages a pin u on the lower movable frame. The latch is held from dropping beyond its 30 docking position by a pin v, which engages an overhanging projection on the latch. The • engagement between the face t’ of the latch ancl the pin u locks the two movable frames together when the upper movable frame is 35 withdrawn. After the latter is withdrawn (half way, a cam plate w, secured to the fixed frame? engages a cam face t on the latch and lifts it into the dotted line position shown in the center of Fig. 5, whereupon the 40 latch overrides the pin u, freeing the lower movable frame from the upper ‘movable frame. At the same time, a stop x on the lower movable frame contacts with a stop x' on the fixed frame and arrests its further 45 outward movement. The outward movement of the upper.movable frame continues and ^:is finally arrested by contact of a stop y thereon with a stop y' on the lower movable frame.

It is apparent that the construction and 50 arrangement of the latches and stops are •such that the operation described takes place whether the movable frames are withdrawn from one end or the other of the cooling •compartment.

After the movable frames are withdrawn to their fullest extent, the containing pan p •may be lifted slightly and moved sidewise (say to the right) for a distance equal to its own width and then dropped so that the up60 wardly projecting wing of the right hand angle bar r engages the pan between its left hand rounded edge z and its adjacent inclined side. So supported along its lefthand side, the righthand 'side may be lowered, 65 thereby facilitating the removal of the body.

It will, of course, be understood that the pan may also be moved to the left and its righthand side supported, as just described, from -the lefthand angle bar r.

While my invention is especially adapted 70 to the purpose herein described, I wish it to be understood that it may also be found applicable to other arts, as, for example, bake ovens and chocolate coolers.
