Specification of Letters Patent.

Patented April so, 1 9707.

Application filed June 20, 1906. Serial NO. 322,626.

To all wh/0771, t ntftjl/ concern: p

Be it known that I, FRANK IV. GowAN, a citizen of the United States, residing at Somerset, in the county of St. Croix and State of IVisconsin, have invented a new and useful Agitator, ol which the 'following is a specilication.

This invention has relation to agitators and it consists in the novel construction and arrangement of its parts as hereafter shown and described.

"he object of the invention is to provide an agitator especially adapted to be used for stirring curd while cooking or 'lirming as heat is being applied to the same. may be used for other purposes.

rl he invention consists primarily of a frame which is adapted to reciprocate over a vat containing the curd. Suitably journaled in said frame is a dasher which enters,

the vat and is provided with two wings which are set at an angle to each other. As the dasher is reeiproeated, it is also swung upon its axis and the wings are consequently moved up and down through the material in the vat. '.lhus the entire body or' material located in the vat is thoroughly worked including such material as may be at the ends of the vat or in the corners olt the same. The curd is evenly distributed and is worked vertically in the vat and longitudinally of the same. The dasher operating mechanism and frame reciprocating' mechanism is also located upon the 'frame and is operatively connected with the parts in order to produce the movements as intimated.

In the accompanying drawings z-Figure 1 is a top plan view of an agitator. Fig. 2 is a side elevation of the upper portion of the same with parts in section. Fig. 3 is an elevation of a-lever mechanism used in the agi tator. Fig. 4 is an end elevation of' the dasher with parts broken away. Fig. 5 is a perspective view of one of the pivots of the dasher and adjacent parts. Fig. 6 is an edge elevation el the dasher actuating mechanism. Fig. 7 is a transverse sectional view o'f one side of the upper portion ol the agitator.

This agitator is adapted to be used on a vat of ordinary construction in which the m aterial is contained. Such vats are usually oblong in horizontal section and they vary in width. Consequently the agitator is made adjustable in order to be applied to vats of di'flerent width.

The agitatorV Frame. The frame consists of the U- shaped members 1, 1 the intermediate portions oi which are adapted to pass over the longitudinal edges of the vat 2 while the ends extend across the said vat, the ends or' one member approximately meeting the ends of the opposite member substantially at the middle of the vat. The ends of the said members 1, 1 ht into the sleeves 3, 3 and the said sleeves are provided with the elongated openings 4 which receive the set screws 5, 5 carried by the ends of the members 1. It will thus be seen that by manipulating the set screws 5 that the opposite members 1, 1 may be moved laterally with relation to each other and through the sleeves 3 secured to each other at such proper relation as to comply with the width of an ordinary vat 2. The track rails 6, 6 are secured to the outer sides ol" the vat 2. The outer sides of the intermediate portions oi the members 1 are provided with suitably journaled wheels 7, 7 which run upon the track rails 6, 6. Thus the frame is supported upon the vat. The motor 8 is located upon one o'l the frame members 1 and is electrically connected with a suitable generator (not shown). The yoke 9 is attached or extends 'from the outer side of the intermediate portion of the frame member 1 upon which the motor S is located. Said yoke is provided with the bracket 10 which is located substantially midway between the ends of the yoke 9 and extends tow ard the vat.

The bearing 11 is located upon the intermediate portion ol one ol' the frame members 1. The bearing 12 is located upon the bracket 1() and is opposite the said bearing 11. The bearings 13, 13 are located in alinement at the lower edge of the member 10. The ends of the yoke 9 are provided with the alined bearings 14, 14 and the inner end of the bracket 1() is provided with the transversely extending bearing 15 which is in alinement with the bearings 14, 14. The bearing 16 is located to one side of the center of the intermediate portion of the 'frame member 1 and bearing 17 is located at the end of the yoke 9 and is in alinement with the bearing 16. The post 1S is located upon the intern'iediate portion of the 'frame member 1 between the bearings 11 and 16. The bracket 19 is attached to the said intermediate portion and is located opposite the said post 18. The said bracket is provided with a IOO IIO

-' to one of the frame members 1.

bearing which is in alinement with the bearing of post 18 and the said bracket is also provided with a bearing 21 which is located below the bearing 20.

I All of the bearings above described are located upon or connected with parts attached The intermediate portion of the opposite frame member 1 is provided with a bearing 22 which is in alinement with the bearing 21 of bracket 19. The outer side of the yoke 9 is provided with the post 23 the upper end of which is bifurcated as at 24 and the bearing 25 is pivoted between said bifurcations. ,The said bearing 25 is adapted to maintain alinement with the center of the core of motor 8.

Bashar. The. dasher consists of the alined shaft members 26, 26. The inner ends of said members lit within the collar 27 and are held in place therein by means of the set screws 28. rl`he outer ends of said shaft members 26 enter the collars 29. Said collars 29 are provided with the squared shoulders 30. lt will thus be seen that the said shaft members 26 may be adjusted longitudinally with relation to each other and secured in proper osition by means of the set screws 28 carrie by intermediate collar 27. The collars 27 and 29 are provided with the depending lugs 31 and 32.

The dasher proper consists of two leaves of similar construction and a description of one will answer for the other. are secured to the lugs 31 and 32 and extend at an angle to each other. Each leaf consists of the bars 33 which are provided with the alined perforations 34. rlhe sleeves are retained in the perforations 34 of the intermediate bar 33. The rods 36 pass' through the perforations 34 of the outer bars 33 and at their inner ends enter the sleeves 35. The strips 37 lare located in suitable perforations provided at the ends of the bars 33,

said strips overlapping each other in the perforations of the intermediate bar 33. It will thus be seen that by means of the sleeves 35 and the overlapping ends of the strip 37 that as the shaft members 26, 26 are adjusted laterally, that the sections of bars 36 and strips 37 are correspondingly adjusted.

The socket members 38 are provided with squared recesses 39 which receive the squared shoulders 30 of the sleeves 29. Said sockets 38 are provided with the lugs 40 which receive between them the enlarged ends 41. One of each set of lugs 40 is provided with a set screw 42 which passes through the lug and is adapted to engage the enlarged end 41. It will thus be seen that the said socket members 38 may be adjusted along the enlarged ends 41. One of the enlarged ends 41 is provided with a pin 43 which enters and rocks in the bearing 22. The opposite enlarged end 41 isV provided with a pin 44 which enters and rocks in the bearing 2l. The gear-wheel 45 .gear wheel 50 is fixed to the said shaft.

The said leaves.

is located on the pin 44. The intermediate bail portions 46 are attached at their downwardly' extending ends to the enlarged ends 41. The upper ends of said bail portions 46 extend toward eachother and are located in the sleeve 47 and are secured therein by means of the set screws 48. By reason of the sleeve 47 and the set screws 48 the said bail members 48 may be adjusted laterally with relation to each other at the same time that the shaft members 26 are so adjusted. The object of providing means for laterally adjusting the parts is to accommodate the dasher to the width of the vat. By providing means for vertically adjusting the dasher members with relation to the supporting pins, the said dasher may accommodate the depth of the vat. It is also obvious that the shaft members 26 and their attachments may be lifted out of the sockets 38 and removed from the vat without disturbing other parts of the device. This is desirable when the contentsof the vat are to be removed.

Operating mechanism. The shaft 49 is journaled in the bearings 14, 14 and 15. The The motor shaft 51 is j ournaled at its outer end in the bearing 25.l The worm gear 52 is located at an intermediate portion of the said shaft 51. The iiy-wheel 53 is located upon the said shaft 51. The gear wheel 50 meshes with the worm gear 52. The beveled gear wheels 54 are loosely mounted upon the shaft 49. Said gear wheels 54 are provided with the clutch collars 55. The clutch members 56 are feathered upon the shaft 49 and are adapted to be slipped in order to engage and disengage the clutch collars 55. Vhen one clutch member 56 is in engagement with its clutch collar 55, the other member 56 is 4out of engagement with its clutch collar and vice versa. The non-rotating rings 57 are located upon the clutch members 56. Saidrings 57 are provided with the lugs 58. The outer ends of the links 59-are pivotally attached to the lugs 58. The inner ends of said links 59 are pivoted to the rocker 60. Said rocker 60 is pivoted upon the exterior of the bearing 12. The crank arm 61 is ournaled in the bearings 13, 13 and to the outer crank end of said arm 61 is xed the weight 62. The pins 63 are located on the outer side of the yoke 9 in the path of the crank end of the shaft 61 and are adapted to limit the rocking or swinging movement of the said shaft. The disk 64 is fixed to the inner end of the shaft 61. The dog 65 is pivoted to the disk 64 and is provided with the bifurcated end 66. The lower end of the rocker60 is located between the bifurcations 66 of the dog 65. rlhe'lower end of the dog is bent at an angle 67. The stops 68, 68 are adjustably attached to the side of the track rail 6 or to the side of the vat 2 and are located in the path of the bend 67. The gear bar 69 is IOO vlixed to the side of the track 6 and extends parallel with the same. The sha'lft 70 is journaled in the bearings 11 and 12. The gearwheel 71 is iixed to the shaft 70 and meshes with the gear of bar 69. The bevel gear wheel 72 is also Vlixe-d to the shalt 7() and is adapted to be in mesh with either' of the gearwheels 54, 54 on the shaft 49.

The mechanism so lar described is adapted to propel the agitator back and-forth over the vat. As the shaft 51 of the motor S rotates, the worm gear 52 meshing with the wheel 50 rotates the shaft 49, one of the clutch members 56 being in engagement with one clutch collar 55, the adjacent bevel gear wheel 54 is turning oppositely with the shaft while the opposite gear wheel 54 is turning upon the shaft 49 but in the opposite direction. The gear wheel 54 that is turning with the shaft 49 rotates the bevel gear wheel 72, shaft 79 and gear wheel 71 in one direction, the gear wheel 71 being in mesh wth the gear ofthe bar 69 and said bar being stationary, the agitator moves toward one end of the vat 2 until the bend 67 strikes the stop 68. Vhen this occurs, the said bend 67 is moved longitudinally and through the dog 65, the disk 64 describes a partial rotation. The shaft 61 being attached to the said disk also describes such a rotation and the weight 62 is elevated and when the crank end of the sha'lt 61 assumes a vertical position, the weight 62 is 1ried over said vertical line and by gravity falls until the end of the shaft 61 strikes the lug 63 located on the side of the yoke 9, it being understood that the lug 63 is located opposite to the said lug from which the said crank end of the shalt 61 is removed. In the meantime the biturca# tions 66 of the dog 65 carry the lower end of the rocker around and consequently the links 59 are moved longitudinally and through the rings 57, the clutch members 56 are moved along the shaft 49 and the gear wheel 54 which has heretofore been rotating with said shaft is released and the opposite gear wheel 54 is fixed to the shaft and caused to rotate with the same. Thus the rotary movement of the bevel wheel 72 is reversed and the bevel gear wheel 71 moves back over the gear rack 69 in the opposite direction. lhen the opposite end of the gear rack 69 is reached, the operation above described is repeated and thus the agitator' is caused to automatically reciprocate back and vforth over the edge of the vat. The dasher leaves being submerged in the contents of the vat, the said contents are worked longitudinally of the vat.

The bevel gear wheel 7 3 is lived te the end of the shaft 49. The shaft 74 is ournaled in the bearings 16 and 17. The bevel gear wheel 75 is iixed to the shaft 74 and meshes with the bevel gear wheel 73. The disk 76 l l l is fixed to the end el the shalt 74. The link 77 is pivoted at one end to the said disk 76 and is pivotally attached at its other end to the lower end of the rocker arm 7 8. Said rocker arm is fixed to the rocker shaft 79 which in turn is journaled in the bearing 20 and post bearing 1S. The gear segment S0 is Vlixed to the shalt 79 and meshes with the gear wheel 45. It will thus be seen that as the shaft 49 rotates, the shalt 74 through gear wheels 7 3 and 75 is rotated as is also its attached disk 76. The link 77 moves longitudinally and rocks the lower end of the arm '78 which in turn rocks the shalt 79. The gear segment S0 is gyrated back and lorth which in turn partially rotates the gear wheel 45 with which it is in mesh. rl`he pins 44 and 43 are correspomlingly turned in the bearings 21 and 22 and the dasher is given a rocking movement at the same time that it is reciprocated back and l'orth in the vat.

The rocking movement above described as being imparted to the dasher causes the movement thereof to move u'p` and down through the liquid contained within the vat and consequently said liquid is worked vertically at the same time that it is being worked horizontally.

Having thus described .my invention, what 1 claim new and desire to secure by Letters Patent is 1. An agitator adapted to be applied to a vat comprising a frame, means l'or adjusting said frame transversely of the vat, a prime mover mounted upon the frame, and a dasher carried by the lrame.

2. An agitator adapted to be applied to a vat comprising a l'rame, a prime mover located upon the Vtrame and actuating the same, a dasher attached to the iframe, and means for adjusting said dasher transversely ol" the vat.'
