FLOOR DRAIN Filed Sept. 28, 1951 2 Sheets-Sheet 2 @60m/ mw/ MY iii) Patented Feb. 9, 1932 UNlTED STATES PATENT OFFICE OSCAR C. SCHMIDT, OF CINCINNATI, OHIO, .ASSIG-NOR TO THE CINCINNATI BUTCHERS SUIPPLY COMPANY, OF CINCINNATI, OHIO, A CORPORATION F OHIO FLOOR DRAIN Application led September 28, 1931.

My invention relates to Afloor drains such as are used in slaughter houses, as in the bleeding floor or so-called bleeding pan, 'for receiving the blood drained from the slauglr tered animal.

The Alloor of a bleeding door or bleeding pau slopes toward an opening', through which the blood is received for being collected, `for instance, in a reservoir or tank, Yfor conser vation and treatment lor consumption as stock toed, and tor other purposes. lt is defiirable that equipment of this nature shall be sanitary and capable ol being readily cleaned.

It is the object of my invention to provide an improved floor drain having a passage through which the blood is arranged to pass, and a passage through which cleansing fluid `is arri ed to pass, with valve mechanism so arranged that when one passage is opened the other is autorfiatically closed; further, to provide such passages with venting means for venting deleterious odors ;V further, to provide :in inlet opening for .such passage, and a trap between said inlet opening and said passage; and further, to provide novel operating means 'for the valves.

My invention will be further readily understood from the following description and claims, and from the drawings, in which latlier:

taken in the plane of the irregular line 7--7 of Fig. and, y

Figs. 8 and 9 are cross-sectional detail views taken respectively on the lines 8*-8 and 9-9 of Fig. 5. y

The bleeding :floor is exemplified at 11. In usual practice the slaughtered animal its suspended above the bleeding floor and its blood drained onto the bleeding floor. The bleeding floor slopes toward my improved device which is arranged to receive blood thus drained.

My improved device preferablycomprises a casing 12 exemplified as a casting. It comprises an inlet compartment 13 and an outlet compartment 14, having a closed wall 15 therebetween, which with a wall 16 forms a trap 17 between the compartment-s.

in outer wall 18 surrounds the compartments. The casing has atop plate 19 in which there are openings 20, Q1. Thetop slate has an inwardly and downwardly sloping peripheral flange 22, the outer margin ot which merges with the upper draining surface 28 of the bleeding floor.

A grating closes the opening 20, being received in a rabbet 26 in theupper "end of the margin of the wall of said opening. The grating has openings 27 permitting flow of the fluid through the grating but arresting solid particles. It is secured `in place by screws 28.

The opening 21 is closed by a sealing plate 31, secured in a rabbet 32 in the upper end of the wall of said opening, as by screws 33, and

having a gasket 34 between it and the lower wall ot' said rabbet. y

A service passage 35 communicates with the outlet compartment 14 and a refuse passage 36 also communicates with this outlet compartment. The outlet compartment is shown provided withv al floor 37 which is higher than the floor 38 of the trap 17. The ports or

openings

89, 40, for said passages are shown in this floor.

Valves 15, 116, are provided for the respective passages, the passages being provided with

valve seats

47, 48, for said valves. These valves are preferably heavy valves, made for instance of metal, so that they will '60, top wall of the casing, being received in a readily close said passages when they descend upon the same. The valve seats and valves are shown of frusto-conical form and vof substantial length.

a plug 62 threaded therein. l An operating rock shaft 65 is pivoted in bearings 66, 67, in the walls of the inlet com-4 partment, the outer wall of-this compartment being provided with a hole 68 through.4

which a suitable tool for finishing said bearingsmay berecei'ved, the holebeing sealed when the device is in use by a threaded plug 69. i

A'yoke 71has hubs 72, 73, about the respective rock shafts k65, 58,' fixed thereto, as b, set screws 74, 75. The rockshafts "are sliown square in cross section, and the openings therefor in the `hubs 72, 73, are shown rectangular in cross section and open at their ends for readily locating the hubs and for readily causing the hubs and shafts to move together. The arms'52, 53,` are extended in opposite directions and have a hub 76 between them, which is provided with a rectangular slot77 having outward opening and'arranged to fit over the rockshaft 58 for being readily received over the rock shaft and held in place thereon by a set screw 78.

The bearings 59, and 60, 67 are also preferably provided with upwardly extending openings so as Vto permit they pivot ends of the rock shafts to be readily received thereof the yoke frame for readily assembling the yoke frame Von the rock shafts. The set screws 74, 75, are in the sidewalls ofthe slots formed vin said hubs. The set screw 78 is also in the `side wall of the hub 76 Vin the rocker frame 51. f

' The bow-end ofthe yoke extends below the Ywall 15 of the trap 17 The yoke frame also has an upwardly extending operating arm 81. 'A'handle'82 has pivotal connection with Ytheupper end of thisarm. The arm extends through a slot 84 in the grating, and the-operating. handle normally lies flat with the recess 85, therein. This recess is shown partly in the-grating plate and partly in the web 86 of the top wall of the casing.

The pivotal connection between the handle and the operating arm is by means of a pivot screw 87. The handle is shown of loop form having an opening 88 through which the fingers or a tool may be readily in-` serted for raising the handle.

Pivot bearings

89, 90, are at the endof the loop and in line with a pivot bearing 91 at theupper end of the operating arm, the pivot screw being received through said bearings and having a threaded connection with one of the end bearings.

When the handle is located in the recess 85, one Vof the valves is in seated relation and the handle is in locked relation to prevent unseating of the valve. .When the other valve is to be seated the handle israised onits pivot and the operating arm swung in its slot toward the other end of the slot, the handle being reversed and again let into itsv recess for positioning the other valve in closed rela` tion and locking the handle in its position. The swinging end of the handle is held in locked relation between end walls 92, 93, of the recess 85. Y Y

' The handle is provided withindicia on its reverse sides to indicate the valve which is open when a given side of the vhandle is uppermost. Thus the handle is provided with the word blood at 94 on one side to indicate that when this side is uppermost the blood 'passage is open, and with the? word sewer7 at 95 on its other side to indicate that when kthis side is uppermost or in view the refuse valve, or valve to the sewer, is open and the Yother valve is closed. Y The valves are preferably heavy plug valves whose connections with their operating means are releasable. Y

The passage 35 is the service. passagek for receiving the liquid to be preserved. A pipe 97 connects with thispassage and leads toa suitable tank 98, the passage 36 is the refuse passage and arranged to receive the water and ingredients when washing and flushing the bleeding floor. A suitable pipe 99 connects withthis passage and leads, for instance, to the sewer. l

A vent passage 101 is provided, shown connected by branches 102, 103, respectively with the service passage 35 andthe refuse passage 36. A pipe 104 is shown connected with the ventl passage, and leads to a suitable exhaust system or through the roof of the building.

The vent passage and its branches are shown'as part of the casting of the casing.

The 'casing is provided with a flange106 which is imbedded, for instance, in the concrete of the floor 11. A

A spring 111 surrounds the rock shaft 65 and exerts lateral pressure upon the yoke frame71 for retarding movement of the yoke frame and holding' it in its Avalve seating positions. It creates friction for instance between the ends of the hub 72 and the bearing 67 when shifting the arm.

My improved device forms a simple and effective means for accomplishing the result desired. It is strong and durable and its valves are readily operable and arranged to be readily seated. The perforated plate Q5 andthe closing plate 3l are readily removable ttor inspection oit.' the par s, the handle 82 being readily removable from the operating arm Sl.

The operating yoke is readily removable 'lrom its rocl shafts by loosening the screws We and 'F5 and shifting the operating yoke laterally for releasing it from its rock shafts. The rocker arm l is readily removable trom roch shaft by loosening the screw 78 and raising the rocker arms trom the shaft, and the valves are readily removable from their operating arms by lifting the same therefrom. The roclt shafts are also readily raised out oi their bearings. The operating mechanism is readily taken apart for cleaning, repairing and attention.

The vent vents each of the passages whether closed or not. and the trap closes each of the passages to the inlet opening. The trap is small in cubic contents but effective in preventin venting trom the respective passages through the inlet opening. The hermetic closing` oi? the outlet compartment compels all matter to pass through the trap betere it reaches either o'l the passages. The location ot the operating member for the valves in the trap avoids the necessity of providing any packing or leak proofing for the operating parts of the valve.

The handle when operated for closing either valve is seated in its recess, the end walls of the recess holding the handle endwise for preventing shifting of the operating parts oli the valves.
