8 Claims. (Cl. 21-24) My invention relates to an apparatus for mixing embalming solutions preparatory toinjection of the same into a corpse.

In the present day practices of embalming dead I :quently spilled on the hands or clothing of the operator or on other objects with objectionable results. It is very desirableto be able to vary the strength of theembalming fluid even during the embalming operation, as during such operation it is necessary to watch the body for evidence of ill effects produced by the embalming fluid which are due primarily to conditions of the body previously caused by the nature of the ailment which caused death and the fact that the solution has not been properly proportioned to meet the particular condition of the body.

The principal object of my invention is to produce embalming apparatus of the class described of simple form and construction by means i of which the concentrated embalming fluid may be exactly mixed with water to produce the desired solution and which apparatus may be readily adjusted during the embalming operation sothat the mixture may be varied as circumstances may require.

Other objects. and advantages will appear hereinafter from the following description and drawing. Referring to the drawing, which is for illustrative purposes only Figure 1 is a diagrammatic sectional elevation showing an apparatus embodying the form of my invention; and l Figure 2 is a sectional view on line 2-2 of Figure 1.

More particularly describing the apparatus shown in the drawing A represents a Jar or reservoir containing the concentrated embalming solution; B a water supply fromjthe ordinary pressure water system; C a water motor; D a pump; and E a mixing chamber. The above; mentioned parts are the general features of the apparatus and are used with proper connections for utilizing the pressure of thewater supply by means of the water motor to operate a pump which pumps regulated portions of the concen- A further objection to trated solution to the incoming water where it is introduced into the water stream after which the mixture passes through the mixing chamber under pressure to a suitable injectorby means of which the fluid is introduced into the body.

The numeral ll indicates a connection to the citywater supply, not shown. This connection is provided with a conduit I2 through which water under pressure is supplied to the apparatus. For the purpose of automatically controlling the supply of water through the conduit l2 a needle valve i3 is provided which engages a seat l4 to shut off such water supply as will hereinafter be more fully described. The conduit 12 is connected to the valve chest i5 of the water motor C, the conduit l2 terminating in a distributing port l6, controlled by a reciprocating valve member l1. The valve chest I5 is provided with ports l8 and I9 whichconnect respectively with passages and 2| at the ends of a cylinder 22, the passage of liquid from the conduit l2 through the ports I! and i9 is controlled by the position of an annular channel 24 in the valve member Il. As shown in the drawing the position of the channel 24 is such that fluid from port I5 is discharged through port l8 to passage 20 then into the cylinder at the rear of piston 25. The outer ends of the passages 20 and 2i are in open com-' munication with a conduit 26 connected to a diversion valve 21. The introduction of fluid to the rear of the piston, as just above described, causes the piston to move in the direction of the arrow until it reaches the end of its stroke and during such movement operates mechanism, hereinafter more fully described, which ,moves the valve member ll so that an annular channel 28 which is now in position to permit flow of fluid from in front of piston to the conduit 26 moves into a position which closes the passage 2|. At the same time that this takes place a channel 30, in the valve member ll, moves into position so that the passage, 20 is opened and the channel 24 moves into position, closing theport l8 and opening the port I9 so that the incoming fluid under pressure from conduit l2 passes to the front of the piston and moves it in opposite direction to that above described.

The piston 25 is flxed to a piston rod 32 which extends through the ends of the cylinder 22, one

end of the piston rod extending into a pump vided with openings 31 to permit some of the liquid in the mixing cylinder to pass through the piston as it reciprocates for the purpose of thoroughly mixing the fluid therein.

The means provided for reciprocating the valve member l1 consists of the following mechanism: Secured to the piston rod 32 is an arm 40 terminating at its upper end in a yoke 4| which engages a circular flange 42 on the end of a valve sleeve 43 which reciprocates in the valve chest 44 of the pump 33. The valve sleeve 43 has the same length of reciprocating movement as the piston rod 32 but it is pointed out that the valve member I1 has a comparatively short movement. To provide for this diflerenceuin movement, the valve sleeve 43 is provided with a slot 45 into which extends a pin 46 on the outer end of the valve member H, which end of the valve member is slidably received in one end of the valve sleeve 43. The slot 45 is less in length than the stroke of the piston rod 32 so that the pin 46 is not engaged by the end of the slot 45 until the piston 25 has nearly reached the end of its stroke, at which time the end of the slot moves the pin 46 and valvemernber l1 a proper distance to bring the channels 24, 28 and 30 of the valve member into proper relation with the ports and passages of the valve chest l as heretofore described. To insure proper position ing of the valve member l1 a spring latch, indicated at 50, is provided mounted at the end of the valve chest l5, which latch engages in V- shaped grooves 5| formed in the end of the valve member l1.

With respect to the feeding and proper mixture of the concentrated embalming fluid, a cup .55 is provided, which in the form shown, receives an upturned bottle or glass jar 56 of concentrated embalming fluid. The fluid emptied into the cup from the jar passes downwardly through a conduit 51 and passage 58 to ports 58 and 60 in the pump cylinder 33. These ports are arranged at the opposite ends of the cylinder and are controlled respectively by ball valves 6| and 62. Ports 64 and 65 are also provided at the opposite ends of the cylinder 33 which connect with a passage 66 which is in open communication with a conduit 61 connected at its other end to the valve 21. The ports 64 and 65,where they enter the passage 66, are controlled respectively by ball valves 18 and 1|. Inside the ball valves 18 and H, the ports 64 and 65 are in open communication with ports or passages 12 and 13, which at their outer ends communicate with the valve sleeve 43. Cooperating with the ports 12 and 13 is a V-shaped communicationport 15 in the sleeve 43 which according to its rotative adjustment, regulates the length of time the ports 12 and 13 are in open communication with each other through the port 15 during the reciprocation of the valve sleeve 43. For the purpose of rotatably adjusting the valve sleeve 43 the outer end of the valve sleeve is provided with alongitudinal groove, indicated at 16, into which extends a spline 11 on an adjustable plate 18; The adjustable plate 18 is provided with a slot 1 8 through which extends a tap screw 80 threaded into the valve chest 44.

It is to be noted that the diameter of the piston 35 in the cylinder 33 is considerably smaller than the piston 25 inthe motor cylinder 22 so that the water pressure moving the piston 25 is sufficient to cause the piston 35 to move the liquid from the pump cylinder 33 through conduit 61 to the valve 21 where, when the valve is in the position shown in full lines, the conduit communicates with a passage 82 in the valve and conduit 83 into the incoming stream of water through conduit l2, the mixture there taking place constituting the fluid heretofore referred to as entering the cylinder 22.

Further explaining the action of the piston 35 in the cylinder '33, as the piston moves in the direction of the arrow from its shown position, valve 6| is opened, valve 62 closed, valve closed and valve 1| opened. The fluid in front of the piston 35 is forced largely through port 65 and passage 13 to the port in the valve sleeve, thence returned to the back of the piston through port 12 and port 64. The amount of such solution permitted to by-pass in the manner just described, regulates the amount of fluid that passes through passage 66 and conduit 61 to the valve 21. On the return movement of the piston the operation of the valves is the opposite to that just described, producingthe same effect of by-passing the large proportion of fluid from one side to the other and pumping a small regulated amount to the valve 21 and thence to the incoming water heretofore referred to. As heretofore described, fluid from the cylinder 22 is discharged through conduit 26 to the valve 21. This valve 21 is of the rotative type and in addition to the port 82 heretofore referred to, is provided with a port 85. This port 65, whenin the position shown in full lines, provides open communication between the conduit 26 and a conduit 86 which connects with the cylinder 34. The fluid passing through the conduit 86, that is, water with the desired proportion of the concentrated embalming solution mixed therewith, is thoroughly mixed in the cylinder 34 from which it is discharged through a connection 88 to a nozzle 88 in a glass container forming a pressure indicating chamber 98 ,which serves as a sight flow and pressure gauge. The inner end of the nozzle 89 is directed laterally and is provided with an annular lip 9| so that the discharge of fluid or rate of flow through nozzle 88 is clearly visible. From the container 90 the fluid is conducted by means of a conduit or pipe 82 and hose 33 to an injection needle 94.

It will be understood that during the operation of pumping the embalming fluid into the body that obstructions are sometimes encountered which must be met by proper regulation of the apparatus and it is for this purpose that the glass container 90 is provided as by the level of the liquid therein, any rise in pressure would be immediately' indicated and if necessary the operation of the apparatus immediately discontinued. The

numeral 95 indicates a pipe or conduit connected to the valve 21 which preferably is provided with a hose connection not shown, to the sink or sewer.

It will be noted that by turning the valve 21, so that the port 85 registers with the valve inlet of conduit 95 and with conduit 26, fluid from the cylinder 22 may be pumped directly into the sink. The same movement of the valve 21 will bring the port 82, as shown in dotted lines, into registration with conduit 61 and a passage 96 which is in open communication with the conduit 86. When this manipulation of the valve has been accomplished the cylinder 22 and piston act only as a pressure pump and it will be noted that straight solution from the pump cylinder 33 is pumped directly into the mixing chamber or cylinder 34 through the container 90 into the body undiluted by mixture of water therewith. At this point it is noted that with an 75 apparatus so arranged other uses for the apparatus are apparent as for instance, concentrated solutions in the form of preservatives or curing materials may be injected directly intomeats such as cornbeef and that for such purposes the desired mixture may be produced by manipulation of the apparatus above described when the undiluted solution is not desired.

Means are provided for permitting automatic shut oil? of the apparatus when the desired amount of fluid has been pumped into the body. This is accomplished by means of a ratchet wheel I mounted on a shaft ml which is engaged by means of a dog I02, mounted on a shaft I03, the dog having an extension in the form of an arm I04 which is adapted tobe engaged by the flange 02 on the valve sleeve 43 when it reaches the end of its stroke as shown in the drawing. :The arm I04 is so operated at theend of each stroke until the dog I engages the needle valve l3 moving the same against thevalve seat I4 thereby shutting ofl the supply of water underpressure with a consequent stopping of the apparatus. The dog I05 is mounted on the shaft IM and secured in adjusted position thereon by means of a nut I06. The dog is provided with markings, such as indicated at I01, which designatemeasured,

quantities of liquids,such as pints or quarts, and by adjusting the dog on the ratchet wheel I00 with respect to an indication thereon designated at I 08 the dog may be arranged to engage the,

valve I3 when a predetermined amount of liquid has been passed through the apparatus.
