JOSEPH J). LACROIX AND AUGUST H. PETERSEN, OF AKRON, OHIO, ASSIGNORS TO KELLY-SPRINGFIELD TIRE 00., OF NEW YORK, N. Y.
MIXING-MACHINE.
Application filed November 8, 1919.
To all whom it may concern:
Be it known that we, JOSEPH D. LAOROIX, a citizen of the United States, residing at 50 est street, Akron, Summit county, Ohio, and AUGUs'r H. PETERSEN, a citizen of the United States, residing at No. 6 1 South Broadway,'city of Akron, Summit county, Ohio, have invented a new and useful Mixing-Machine, of which the following is a specification.
Our invention relates to a machine for mixing powder, plastic, or granulated materials, or mixing powder materials with plastic materials, such as lamp-black with unvulcanized rubber and similar substances, particularly mixing impalpable powders that readily fly about, pollute the atmosphere and are wasted in the mixing operation. We eliminate these and other objectionable features attending the mixingof powdered materials by inclosing the entlre mixing apparatus in a dust proof,pract1- cally an air tight chamber during the operation. .The machine consists of a revolving dust proof barrel shaped cylinder or tumbler, equipped internally with conveyer pockets or ribs and inclosing a pair of separate and independent water cooled revolving cylinders or rollers which revolve in opposite direction, and in conjunction with the revolution of the tumbler casing and conveyor pockets. This arrangement produces a thorough mixing of powders and a thorough kneading of plastic material without waste and resulting in a great saving of expense and the absence of the unsanitary results usually attending the working up of deleterious or impalpable powders such as the coloring matter used in rubber compounds and similar substances. The mechanism of the machine is shown in the accompanying drawings of which' Figure 1, is an outside view of one side of the entire machine, the driving power omitted. Fig. 2, is a plan view of the machine, driving power omitted, Fig. 3 is a cross sectional view taken substantially on line w-a of Fig. 2. Fig. 4;, is a vertical sectional view taken substantially on line b-b of Fig. 3. Like numerals refer to like parts in all figures.
The barrel shaped chamber or tumbler 4, is equipped with internal conveyer pockets 5-5 which help to keep the contents of the chamber in constantly changing relations.
Specification of Letters Patent.
Patented June 22, 1920.
Serial No. 336,638.
A large part of the upper half of the cylinder constitutes a door 1 which opens on hinge 6, and is secured by clasp 7. This door when closed forms a part of the chamber casing. The inside of the ends or edges of the cylinder portion of the chamber revolve around and on the edges of the circular stationary ends 8, as shown at the point 9. Theouter edges of the cylinder portion are furnished with gearings 10, WlllCll engage with gear wheels 1111, which last mentioned wheels are rigidly mounted on the counter shaft 12, and which counter shaft with the gear wheels 11-11 is operated through spur wheel 13 controlled by clutch 13", which spur wheel 13 is rotatably mounted on driving shaft 14. Said driving shaft 14 being rotatably mounted in bearing 15. On driving shaft 14 is rigidly mounted belt wheel 16, through whlch power is applied to operate the entire machine. On driving shaft 14 is also rotatably mounted spur wheel 17 controlled by clutch 17*, which spur wheel 17 engages with and operates large gear wheel 18, and which large gear wheel is rigidly mounted onshaft 19 which is an extension of one end of mixing roller 20. The opposite end of mixing roller 20 also has an extension in the form of a shaft 19 on which is rigidly mounted gear wheel 21, and this last mentioned gear wheel engages with a somewhat larger gear wheel 22 (best shown in Fig. 2), which gear wheel 22 is rigidly mounted on the shaft end 28 of the other mixing roller 20".
It will thus be seen that the driving shaft 14, and the spur wheel 13, drives gear wheel 11, and its companion gear wheel 11 both on the counter shaft 12, and these in turn revolve the barrel shaped chamber which is equipped with gearings 10 on the outside of each end; at the same time spur wheel 17 drives the large gear wheel 18 which is rigidly mounted on shaft end 19 of mixing roller 20; mixing roller 20 drives its companion mixing roller 20 through gear wheel 22 which last mentioned wheel is rigidly mounted on the shaft end 23 of mixing roller 20.
The function of gear wheels 24 which .synchronize with gearing 10 is to prevent vibration and help steady the revolving cylinder; rollers 25 mounted on shafts 26 also perform the same function.
Chamber heads 8 are rigidly secured to the bearings 27 by tie plates 28, andin the bearings 27 are revolubly mounted roller shaft ends 1919, 23 and 23, and the bearings 27 and 29 are rigidly mounted on a suitable bed piece.
The shaft ends l9 and 23 have central conduits or -bores 30, 30 connected with water conducting pipes, 31, 31 through which conduitswater is forced into roller chambers 32, 32. lVithin said conduits are located waste water pipes 83, 33" of considerable smaller diameter than the conduits; cold water is forced into the roller chambers through the conduits and the waste water pipes 33, 33 carry off the same serv ing to keep a body of cold water in the roller chambers at all times, and thus prevent over heating of the mixing rollers.
The plates 34, 345 tend to prevent the material from being pressed out at the ends of the rollers.
On theedge of the door we attach a suit able packing 35, and it will be understood that suitable packings may be used elsewhere to make the mixing cylinder dust tight.
