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, 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the main objects of the invention is to provide means whereby the sectional frame supporting the containing pan may be withdrawn from, and inserted within, its cooling compartment from either end thereof, which capacity is of great value, and utility in mortuary refrigerators.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 frames in traveling relation one upon another and both upon the Xed fra-me. Another object of the invention is to provide means for locking one movable frame to the other for part of their travel, and then automaticallyunlocking 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 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 l 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. 4E is a sectional view of same on line 1 -4C of Fig. 3. f
Fig. 5 is a broken elevational view showing the working of the automatic latches.
Fig. 6 is an enlarged cross-section on line 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. 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 the lower edges of the door-jambs (see Fig. 1 and about in line vertically with the upright edges of the door j ambs (see Fig. 3).
The cross-sectional shape of the channels,
which is virtually that of a square, is clearly shown in Fig. 6. A longitudinal opening d, the edges of which are turned downward7 is provided in the upper face.
Within each channel is ,confined three pairs of rollers c, which are supported from the downwardly depending angle bars f of the lower movable frame, which also comprises cross bars g, lling strips 7L and angle bars c', the latter supporting pairs of rollers The angle bars are secured to the cross bars and,4 between the cross bars, are spaced apart by the filling pieces.
The rollers Z0 are confined within channels m, which are located directly above the channels c and are connected together by rods n upon which are sleeved rollers 0. The parts m, n and 0 comprise the upper movable frame.
Channels c and m are of the same size and construction, being merely inverted relatively to each other. The angle bars j and z' 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 description, that the lower movable frame is capable of rolling in a longitudinal direction upon the Xed frame, and that the upper movable frame is similarly capable of rolling upon and relatively to the lower movable frame. I
The containing pan p is adaptedto resl and roll upon the rollers o and is provided with longitudinal rounded or beaded edges e which are adapted to slide upon longitudinally extending angle bars r secured to the upper faces of the channels m. Either the rollers 0 or the horizontal wings of the angle bars 1' afford an adequate support for Y fthe upper movable frame, the lower movable frame is locked to and moves with it. At the ibeginning of the rlatter half-of the movement ofthe upper movable frame, further movement of the lower movable frame is arrested and the upper movable frame is unlocked from lthe lower movable `frame and moves independently. The means for latching and runlatching the two movable frames and for .arresting their movement, whether the mov- -able frames are withdrawn from one end or lftheothero'f the cooling compartment, will now be described.
Secured -to eachendof `the upper movable fra-me lis `a pivoted latch t (see Figs. 5, 6 and 7)V having a nearly verticalV face t. which en- `gages a pin u on the lower movable frame. rlhe latch is held from dropping beyond its :locking position by a pin v, which engages an overhangingf -projection on the latch. The
-`engagement between the face t of the latch and the pin u locks the two movable frames l together when the upper Vmovable frame 1s withdrawn. lAfter vthe `latter is withdrawn half way, a-cam plate lw, secured to the fixed frame, engages a cam face t on the latch fand lifts it -into the dotted line position shown infthe center of Fig.V 5, whereupon the latch overrides the pin u, freeing the lower 4movable 'frame from ythe upper 'movable frame. At the same time, a stop on the lower movable framecontacts with a stop x on the Xed frame and arrests its further outward movement. The outward-movement vof the uppermovable frame continues and is finallyarrested by contact `of a stop y thereon witha stop y on the lower movable frame.
AlEt is apparent that the construction and arrangement of the latches and stops are 'suchthat the operation described takes place whether fthe movable frames are withdrawn Nfrom one `end 4or the other of the cooling compartment.
A-'fter the lmovable frames` are withdrawn totheir '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 upwardly projecting lwing` of `the right hand angle bar 1 engages the pan between its left hand rounded `edge 'e and its adjacent in- Iclined side. So supported along,` its lefthand side, the righthand side may be lowered,
-=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 lcfthand angle bar r.
lf'lhile my invention is especially adapted to the purpose herein c escribed, l wish it to be understoodthat it may also be found applicable to other arts, as, for example, bake ovens and chocolate coolers.
Having` now fully described my invention, what I claim and desire tov protect by Letters Patent is l. ln an apparatus of the character described, the combination with an intermediate movable frame comprising'y members projectinp,` upward and downward therefrom and rollers carried by both members,of a lower fixed frame and an upper movable frame, each of the last two frames compris- .ing channels inclosing the corresponding rollers, the latter beingconiined between the upper'and lower walls of the channels.
Q. ln an apparatus of the character described, the combination with a cooling compartment provided with doorways at opposite ends thereof, of va fixed frame within the compartment, and two frames. superimposed upon the fixed frame and confinable within said compartment and also 'initially movable 'as one'longitudinally relatively to the iixed frame and finally movable'relatively to each other, through either of said doorways.
3. in an apparatus of the character cescribed, the combination with a cooling compartment provided with ydoorways at opposite ends thereof, of a fixed frame within the compartment, a movable frame slidable longitudinally upon the fixed frame .through either doorway, stops limiting the outward movement of the movable frame in both directions, a second movable frame slidable longitudinally in opposite directions initiallyI with and finally upon the first movable frame beyond both ends thereof, and stops limiting the outward movement of the .second lmovable frame in opposite directions. f
4. 'ln an Vapparatus. of the character described, the combination with a cooling compartment provided with doorways at opposite ends thereof, of a iXed frame within the compartment, two movable frames superimposed upon the fixed frame and containable within the compartment, locking vmeans securing the movable frames together when `the upper movable frame is initially pulled outward through either. doorway, and means operative, during said movement, to release said locking` means and allow the upper movable frame to move outwardly beyonr the lower movable frame.
ln testimony of which invention, I 'have hereunto set my hand, at Philadelphia, on this -l'lth day of "October, 1917.
