To all whom t may concern.'

Be it known that I, WILLIAM F. MORSE, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Mixing- Machines, of which the following is a specilication.

The object of this invention is to provide a new and improved form of mixing machine which is especially adapted to mix paste or other similar material.

This and other objects of the invention will be fully illustrated in the drawings, described in the specification and pointed out ,in the claims at the end thereof.

In the accompanying drawings,

Fig. 8 is a longitudinal sectional View of the can shown in Fig. 7.

Fig. 9 shows a modified form of fastening the can to the turn table.

In the several figures of the drawings like reference numerals indicate like parts.

As illustrated in the drawings the machine is mounted 0n the base 1. This base is provided with the brackets 2 and 3 on one side thereof and has bolted thereto the bracket 4 on the opposite side thereof. The brackets 2, 3 and 4 are supported by suitable blocks and 6 for the purpose of raising the base 1 to a predetermined height from the floor.

The base 1 as shown infFigs. 1 and 2 comprises a cylindrical casing which is closed at the bottom and is open at the top. In the center of the lbottom 7 of this casing is provided a lug 8 which projects into the casing andcarries at the top thereof the center pin 9. This center pin has a shank 10 of reduced diameter which projects into the hollow center of the lug 8 and is held suspended therein by means of the shoulder 11 formed between the pin 9 and its shank 10. As shown in Figs. 2 and 3 suitable reinforcing ribs are provided on the inside of the casing, which ribs run radially on the bottom 7 of the casing from the wall 12 to the lug 8 in the center of the casing to increase the supporting strength of the lug 8.

On the inside of the wall 12 are provided the pockets 13, 14 and 15 in which are mounted to rotate the antifriction rollersl, 17 and 18 respectively. Mounted to rotate on top of these rollers is the turn table 19 whichy comprises a circular plate 20 having j an annular flange 21 projecting downwardly at its periphery thereof.

In the center of the turn table 19 and on its under side thereof is provided a lug 21. This lug has a cylindrical pocket 22 in the center thereof into which pocket projects the center pin 9.' The turn table 19 is provided on its under side with a circular track 23 which rests on the antifriction rollers 16, 17 and 18 and by which the turn table 19 is supported on the base 1.

The turn table 19 is also provided on its under side with a circular yrack 24 which meshes with the pinion 25. The pinion 25 is keyed to the end of the shaft 26, which shaft is mounted to rotate in the bearing 27 formed in the bracket 4, as shown in Fig. 3. Mounted on the outer end of the shaft 26 are the pulleys 28 and 29, the pulley 28 being keyed to the shaft 27 and the lpulley 29 being mounted to rotate idly thereon. A belt (not shown) is used to drive these pulleys and may be shifted from one pulley to the other by means of the belt shifter 30. This belt shifter comprises a rod 31 which is mounted to slide in the bearing 32 and has keyed thereto suitably spaced apart the depending arms 33 and 34. These arms are adapted to straddle the belt and prevent its movement sidewise except when itis desired to shift the belt from one pulley to the other, in which case the arms 33 and 34 are moved to guide the belt onto the adjacent pulley.

The bearing 32 in which the rod 31 is adapted to slide is formed ony the upper end of the bracket This bracket is supported on a sleeve 3G which in turn engages the rcduced end 37 of the bracket el. A set screw 38 passes through the sleeve 3G on-its under side thereof and holds the sleeve rigidly inY place on. the end of the bracket t.

rhebiacket l has a vert-ical extension 39 provided thereon at the end ofv which is formed the flange l0. A sleeve ll having a flange 42 provided thereon is clamped on top o-f the flange by nieans of the bolts l and rigidly supports the upright lil on top of the extension 39 of the bracket l; the upright il being fastened into the sleeve il to forni an extension thereof. The upright all has an arin 45 clamped to the upper end thereof which arni is provided With'an adjustable sleeve e6. Passing through the sleeve and rigidly clamped in place` therein is the pipe e7. rlhis pipehas a reducing nipple S at the upper end thereof into which is fastened the pipe 49 which connects the l 50 with the pipe e7. A flexible hose 57 is connected to the T 50 at right angles to the pipe by means of the union coupling 58, Which hose forms the ste-ain inlet to the pipe e7. The adjacent opening of the 'l' 50 is plugged up and is provided with an eye 5l into which engages the hook 52 carried on the end of the cablet. The cable 53 passes over suitable pulleys 5l and 55 and carries on the other end thereon a counter-Weight 56 which is used for a purpose that will presently appear. v

The top surface ofV thevturn table 19 has the lugs 59, 60 and G1 rigidly fastened thereto near the periphery thereof. rlhe inner end of each of these lugs fornis a groove `with the top surface of the turn table vvith Which the riin (52 of the can 63 is adapted to engage. The lugs 60 and Gl are located slightly on one side of the center of the turn table in the direction toward the lug 59 to allow the can 63 to be niovcd onto the top of the turn table until the riin 62 thereof engages the grooves formed by the lugs 59. GO andGl. Asinall post te is then inserted into the opening `66 provided in the top surface of the turn table in front of the can. This post has a set screw 67 passing therethrough which can be adjusted to enga O'e the reinforcing strip GS fastened to the periphery of the can 63 as shown in Figs. l and 3. In this manner the can may be clamped between the lugs 59. G0 and Gl and the post 65 on the platform of the turn table and rigidly heldin place thereon.

After the can 63 is fastened to the turn table 19 in the manner above described the pipe f7 is inserted into the can 63 and isheld stationary suspended therein by means of the clamping sleeve -lG as shown in Fig. l. In this position the branch pipe which is G9 connected at right angles to the pipe ll' at `the Wall of the can.

Leer/,57e

the lower end thereof is held suspended slightly above the bottom of the can 63s() that the steam which passes through the pipe i7 into the pipe 69 can escape into the mixture contained in the can through suitable openings 7 0 provided on the under side of the pipe for a purpose that will presently appear.

Claniped to the pipe Li7 above the branch pipe 69 and suit-ably spaced apart thereon are the stationary mixing paddles 71 72, 73 and 7l. Each of these paddles comprises a pair of arins 75, having a section 76 of a sleeve provided on one'end thereof. A lug 77 projects outwardly from each ofthe sections 7 6 in the opposite direction to its arin 75. rlhe sleeve sections 76 of each pair of arins 75 embrace the pipe 4:7 and are ar# ranged so that one of the arms projects to the right of the pipe and the other-'to the left thereof. Bolts 78 and 7 9 pass through rand clanip the bracket 80 in place thereon.

To hold the bracket S0 firmly in place on the inside of the can 63 two pairs of lugs S-lfand '85 are provided near the bot-toni and top of the can. Each of the lugs has an angular projection Which forins a short channel with Each pair of these channels formed by the lugs 84:- and 85 respectively is adapted to receive the enlarged ends 86 and 87 of the bracket 8O and aid the set screw 83 in holding` the bracket 80 rigidly in place on the inside of the can 63.

The bracket SO has a series of ar is S 89, 90 and 91 integral therewith and projecting at right angles thereto. These arins are suitably spaced apart so that they project into the spaces formed between the paddles 71. 72, 73 and 74; as shown in Fig. 5;

ln (l is shovfn a modified vforni of can lll 99 having ratchet like ridges fornied on the i Wall of the can. rl`he paddles 93 used in connection ivith this can are curved' and are rigidly` heldin place on pipe 47 as shoivn in this gure. This type of can and paddlesinay be used for special purposes Where no rotating paddles are required.

Figs. 7 and 8 show stillV another type of can and mixing paddle therefor. The Walls of this can are corrugated as shown at The paddle 94 used in coimectionwith this type of can comprises tivo pairs of arrnsv95 similar to the arms shown in Fig. 5 and numbered 72, 737 7l, and 7 5. The arnis 95 suspended therein as shown Vin Fig. 5.

are clamped to the pipe 47 in the manner described in i connection with the arm 71, etc. and are suitably spaced apart. The outer end of each of the arms 95 is curved in such a manner that the arms on one side of the pipe curve in one direction and the arms on the other side curve in the opposite direction.

Fastened to these arms on each side of the pipe 47 is a blade96 and 97 respectively. Each of these blades is provided with the slots 98 and 99 through which pass the clamping'screws 100 by which these blades are clamped to the ends of the arms 95. The slots 98 and 99 permit an adjustment of the blades on the arms 95 so that they can be moved toward or away from the corrugated wall of the can.

When only the mixing paddles shown in Figs. 6, 7 and 8 are used the pipe 47 is closed at the `end by means of the cap 101 as no steam is used when the machine is operated with any of these paddles. It will be understood, however, that steam may be used in connection with these paddles if desired.

The operation of the machine is as follows: l f

The ingredients for the paste are inserted into the can 63 which is then slid on top of the turn table 19 until the lower edge thereof engages the lugs 59, 6() and 61. The post 65 is then inserted into the opening 66 provided inthe turn table and the set screw 67 mounted in the post 65 is screwed against the reinforcing strip 68 provided on the can 63 so as 'to firmly clamp the lower end of the can between the lugs `59, 60 and 61 and the post 65. f

The pipe 47 with the paddles 71, 72, 73v

and 74 clamped thereon may then be lowered into the inside of the can and properly heIld y n this gurethe paddles 71, 72, 73 and 74 project into the spaces provided between the paddles or arms 88, 89,- 90 and 91 on the bracket 80 so that on the rotation of the can 63 to which the bracket is clamped the arms 88, 89, 90 and 91 do not strike the paddles 71, 72, 73 and 74.

Power is then applied to pulley 28 to rotate the shaft 27 and with it the pinion 25 keyed to the inner end thereof. The pinion 25 meshes with the circular rack 24 provided on the under side of the turn table 19 so that on the rotation of the pinion 25 the. circular rack 24. and in turn the turn table 19, is rotated around the stationary center pin 9.

The antifriction rollers 16, 17 and 18, mounted to rotate in the base 1, support the turn table 19 and eliminate unnecessary friction between the turn table 19 and the base 1 and permit its easy rotation thereon. The can 63 clamped to the top 0f the turn table 19 rotates with the turn table so that the arms 88, 89, 90.1and 91 revolve around the pipe 47 and between the paddles 7 0, 71, 72 and 73, and thoroughly mix the ingredients contained in the can. The can is kept rotating until the paste is properly mixed and ready for use.

Either before or after or during the rotation of the can containing the ingredients of the paste, steam may be applied thereto to cook the contents of the can. This is done by admitting steam through the flexible hose 57 into the vertical pipe 47 and the cross pipe 69 from where it passes out into the paste in the can through the opening 70 provided in the cross pipe 69.

After the paste is properly mixed and cooked by means of the mechanism above described, the clamping sleeve 46 is opened to allow the counter-weight 56 on the end of the cable 53 to pull the pipe 47 and its paddles 70, v71, 72 and 73 out of the can 63 and permit the removal of the can from the turn table 19 to make room for another can which may have been prepared for mixing while the contents in theiirst can was mixed by the machine.

The bracket 80 with its arms 90, 91 and 92 is disconnected from the first can and may be inserted into the next can which is then ready to be clamped to the turn table and rotated in the manner above described.

When using the can and paddles shown in Figs. 6,7 and 8 the paddles are so adjusted that the contents of the can is forced against the wall of the can. The rubbing action of the corrugated wall of the can'thus gradually reduces the lumpportions of the paste.

Instead 0f locking the can 63 on to the turn table 19 by means of the post 64 and the set screw 67 a ypin 102 may be inserted into the 0pening'66 of the turn table. This pin is adapted to make engagement with `one of the wedge shaped lugs 103vr which are fastened to the can 63 on either side thereof as shown in Fig. 9. When the turn table 19 is rotated in the direction of the arrow shown in this figure the pin 102 moves up the inclined end of the wedgeshaped lug 103 and gradually shifts and forces the lower end of the can against the lugs 59, 60 and 61 and clamps the edge 62 thereof between these lugs and the pin 103. To unlock the can 63 from the turn table 19 thc can is given a short twist in the ,opposite direction from the arrow which dis-r engages the pin 102- froin the wedge-shaped lug 103 and allows the easy removal of the pin 102 from the turn table.
