invention will be apparent from a reading of the following description in connection with the drawings wherein a preferred embodiment of the invention is shown for illustrative purposes.

In the drawings:

Figure 1 is a general top plan View of the embodiment.

Figure 2 is a general side elevational view thereof, with portions broken away to show interior mechanism.

Figure 3 is an enlarged transverse vertical sectional view taken through the cylinder and showing the combined valve and piston in disassembled condition.

Figure 4 is a top plan view of Figure 3.

Referring in detail to the drawings, the numeral 5 generally designates a vertically elongated cylinder rising from a laterally extending base 6 which is adapted to rest upon a supporting surface (not shown) and to be properly levelled by means of leveling screws 1 threaded through the base. The upper end of the cylinder is closed by a top 8 which has an axial threaded filling opening 9 therein which is closed by a threaded plug I0. A pressure gauge II communicates with the interior of the cylinder through the said top 8 at one side thereof and in a diametrically opposite position one side of a flow control valve I2 has communication with the interior of the cylinder through the said top 8. In a circumferentially spaced position adjacent the pressure gauge II a by-pass valve I3 is mounted on the said top 8 and has communication with the interior of the cylinder 5.

At the lower end of the cylinder 5 a water exhaust control valve I4 has communication with the interior of the cylinder adjacent the base 6 and in a diametrically opposite position is the water inlet valve I5 which also has communication with the interior of the cylinder at approximately the same level as the valve I4.

A swivel coupling I! is connected to the valve I2 and the coupling has extending therefrom the injector tube I8 which leads to the body to be embalmed. The valve I4 is connected to a drain hose I9 leading to a drain (not shown) while the valve I5 is connected to a water supply pipe 23 and interposed between the supply pipe 20 and the valve I5 is a T-coupling 2I which has connected laterally thereto the reduced diameter by-pass pipe 22 which is connected with the bypass valve I3. All of the various valves described have manual controls whereby the flow through the various valves may be accurately adjusted.

Vertically movable within the cylinder 5 and capable of falling therein from an elevated position to a depressed position by the force of gravity is the combined piston and valve which is generally designated 23 and comprises a cage comprising upper and lower rings 24 and 25, respectively, spaced and connected by a vertical bars arranged at substantially equally circumferentially spaced intervals.

Secured to the upper ring 24 is a substantially rigid metal disk 21 which is smaller in diameter than the ring 24 which has a comparatively close fit in the cylinder, the disk 21 having its circumferential edges beveledas indicated by the numeral 28. Above the metal disk 21 are two leather or similar material disks 29 and 30, respectively, which are similar but reversed in position, the angulated wall 3| of the upper disk being in an inclined position, with the wall 32 of the lower disk in a declined position and forcibly engaging the interior of the cylinder 5. Above the sealing disks 29 and 30 is the clamping disk 33 of suitably rigid material and which is of a diameter smaller than that of a sealing ring so as to engage the upper ring 29 only within the beveled wall 3|. The area of the lower metal disk 21 within its beveled edges is approximately the same as the area of the upper clamping disk 33 so that the two disks 2'! and 33 cooperate in clamping the sealing disks together on the valve cage in a manner to leave the beveled walls 3| and 32 of the sealing disks free to flex. A rivet or the like 34 is provided to pass through axial openings in the various disks to clamp the same on the valve cage 23 in the assembled relation illustrated in Figure 2 of the drawings.

To operate the present device the filling opening cover I0 is removed and the combined piston and valve 23 is placed at the lower end of the cylinder 5 and all of the space within the cylinder below the valve 23 is then entirely filled with water by opening the water inlet valve I5, thereby allowing the air above the combined piston and valve 23 to exhaust through opening 9. At this point when the combined piston and valve 23 reaches the top of the cylinder the inflow of water from inlet valve I5 will cease and said inlet valve I5 is manually closed. The water exhaust valve I4 is then opened to allow the water below the piston to discharge into the drain, thereby allowing the combined piston and valve 23 to settle by gravity toward the bottom of the cylinder 5. When the combined piston and valve 23 reaches the lower end of the cylinder the water will cease flowing through valve M due to the valve occluding position reached by the piston 23. At this point valve 14 is manually closed. At this period in the operation the desired number of ounces of concentrated embalming fluid is poured through the opening 9 above the piston 23 and the water intake valve I5. is then opened to allow water from the water supply to enter the cylinder below the disk 21 of the piston 23 and thereby cause the piston to rise in the cylinder and push the embalming fluid above it toward the top of the cylinder, thereby forcing out of the cylinder through the opening 9, any air which may be in the cylinder. When the embalming fluid has been pushed to a level even with the top of the cylinder the valve I5 is closed and the cover I!) then replaced and screwed down tight. The device is now ready for mixing the concentrated embalming fluid with water above the piston 23. To eflect this the water'exhaust valve I4 is opened to allow the water below the piston 23 to drain out and the by-pass valve I3 is opened to allow water under pressure from the supply to flow through the by-pass 22 into the cylinder above the valve 23 and mix with the concentrated embalming fluid therein and at the same time force the piston downwardly. When the piston 23 reaches the bottom of the cylinder, having forced out the water below it through the hose IS, the piston prevents the mixture of water and embalming fluid above it from exhausting through the valve I4 due to the valve occluding position reached by the piston 23. The stopping of the piston in the bottom position also prevents any more water from entering the space above the piston through the by-pass 22. The device is now ready to start injection of the diluted embalming fluid resident in the cylinder 5 above the piston-23 into the artery of the corpse via the pipe or hose 18. To accomplish injection both the water exhaust valve I4 and the by-pass valve l3 are closed and the injecting fluid flow control valve 12 is opened a predetermined amount to provide the desired rate of flow of the embalming fluid from the hose 18. The water inlet valve I5 is then opened to let the water under pressure from the supply to flow into the cylinder under the piston 23 until the pressure gauge II shows that a pressure has been developed within the cylinder and above the piston exactly equivalent to the injection pressure desired. This pressure is maintained until the embalming fluid above the piston 23 is exhausted by progressive upward movement under hydraulic pressure of the piston 23-, and thereby injected into the corpse.

It will be obvious that the embalming pressure and the rate of injection of the embalming fluid is controlled by controlling the rate of flow at which the water from the Water supply, such as the ordinary water main, is allowed to enter the cylinder 5 below the piston 23. When the piston 23 reaches the top of the cylinder it is stopped by engagement'with the head 8 and is then in such a position that it occludes the valves I2 and I3 in the head of the cylinder, thereby preventing water from the supply from exhausting through the injecting valve l2. It is obvious that when the piston stops at the top of its rise and the water pressure under it in the cylinder equals the supply pressure, no more water enters the cylinder through the valve l5. Thus the piston acting as a stop valve allows only a predetermined amount of water to enter the cylinder when it is filled and automatically stops the action of the device when the predetermined amount of embalming fluid above the piston in the cylinder has been injected into the corpse. It is obvious that the rate of movement upwardly of the piston is governed by the adjustment of the valve l5, supposing a constant water supply pressure. It will be obvious from a consideration of the foregoing that all air being exhausted from the cylinder as a result of the operation of the piston, no air or gas can develop in the device which would be injected into the corpse with the embalming fluid, thereby obviating an objectionable condition associated with other injecting apparatus.

Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of my invention thereto, except as may be required by the scope of the subjoined claims.
