AGITATING DEVICE.

Specification of Letters Patent.

Patented Feb. 25, 1913.

To all whom it may concern:

Be it known that I, JOHN H. Ha'rirawar, a citizen ot the United States, and a resident of the city of hlaywood, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Agitating Devices, of which the following is a specification.

My invention relates to agitating devices and more specifically to that class thereof which are designed for employment in the breaking of lead or paint.

The object of my invention is the production of an agitating device as mentioned which will be of improved construction and eitlicient in operation.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements oit' parts hereinafter described and claimed.

The invention will be more readily understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a frontelevatjion of an agitating device embodying my invention, the upper end portion of the operating handle and the dasher plate shaft being broken away, the device being shown arranged in operative position in a paint keg, the latter being shown in section, Fig. 2 is a top plan view, Fig. 3 is a section taken on substantially line -fa of Fig. 2, Fig. et is an enlarged detail central section of the dasher shaft bearing and the supporting arms therefor, Fig. 5 is a section taken on substantially line q/-g/ of Fig. 4l, and F 6 is a section taken on substantially line z--s of Fig. Il.

The preferred form of construction as illustrated in the drawings comprises a shaft or bar l which is of elongated rectangular form. Arranged at 'the lower end of the shaft t1 is a dasher plate 2 which is of rectangular form and provided with rectangular perforations asA shown, the perforations in one end being larger than those provided in the other. The dasher plate 2 is secured at its center to the shaft 1 by means of a rivet 3 which permits ot' rotatable adjustment of said plate in a vertical plane. Said plate is held in positions of adjustment by means of bolts and nuts 4t which pass through alining perforations provided in the shaft 1 and the respective ends of said d asher plate; there being perforations 5 pro vided medially in the longitudinal edges of the plate arranged at the same distance from the pivot point of said plate `as the perforations engaged by the bolts and nuts 1l as shown. rlhe arrangement is such as will be observed that the member 2 may be rotatably adjusted so as to position the longitudinal sides thereof in a horizontal plane, the plate, when thus positioned being adapted for employment in a paint keg larger than that in conjunction with which it is shown inthe drawings. The preferred arrangement of the plate is that shown in which the smaller` perforations and those which are spaced farthest apart are positioned at the lower end of the plate. Vhen thus arranged the dasher is adapted when oscillated in the keg to break the lead, paint, or other solid matter in which the same is operated. The denser mixture of lead and oil or of the paint pigment and the oil remains at the bottom of the keg, the less dense mixture remaining at the top, hence the reason for positioning the plate with the end containing the smaller pertorations spaced farthest apart below, to etlectually agitate the portion of the mixture most needing agitation. Also, with this ar 'angement the thicker liquid will low through the perli'orations in the upper end of the plate faster than will the denser mixture passing through the perforations in the lower end. This being so an upward flow or current in the liquid will be created from the lower end ot' the plate toward the upper, thereby effecting a more etlicient and thorough mixing and agitation ot the substance which is being operated upon. lllowever, where the lead or paint Vpigment is exceptionally thick at the bottom it is advisable to invert the dasher during the eomniencement of the operation. The adjustments referred to may evidently be made with ease and expedition by simply removing the bolts and nuts 4.

The upper end portion of the shaft l is mounted in a holder consisting of the tube 6, the lower end of said tube being plugged and provided with a rectangular slot or recess 7 adapted to snugly receive the upper end of shaft l., thus serving to lock the shaft to said tube. The tube G is rotatably mounted in a bearing member 8,longitudinal movement of said tube in the member 8 being prevented by means of thrust bearings which consist of the annular bearing members 9 and 9, the former being pinned to the lower end of the tube G and the latter threaded upon the upper end of said tube, said members 9 and 9 cooperating with

members

10 and 10 rigidly secured in the respective ends of the member 8, there being bearing balls 11 interposed between the adjacent ends of the

members

9 and 10 and 9 and 10. The bearing member 9 being threaded upon the tube G affords adjustment of the thrust bearing, that is of the

members

9 and 10 and 9 and 10 relative to the balls 11, said member 9 being locked in positions of adjustment by means of a lock nut 12 between which and the member 9 is interposed a washer 13, an inwardly projecting finger- 111 provided upon said washer engaging a longitudinally extending slot 14 provided in the tube 6 to hold said washer against rotary movement. Shaft 1, it will be observed, is free for vertical movement in the bearing and so that if desired the device may be operated with the dasher member 2 resting directly upon the bottom or lower head of the keg. If

this is not desired because of roughness of j the keg, the shaft 1 and hence the dasher may be held in slightly elevated position by means of a cotter pin 15 which is adapted to engage with any one of a series of perforations 16 provided in the upper end of said shaft, said cotter pin when in position abutting against the upper extremity of the tube 6 as clearly shown in Figs. 1 and 3.

Formed at the lower end of the bearing member 8 at opposite sides thereof are laterally vprojecting shanks or extensions 17, upon which are loosely mounted supporting arms 18, the shanks 17 slidably engaging sockets provided in the inner end portions of the members 18, said shanks and said sockets being preferably square in cross section to prevent 'relative rotary movement. The members 18 are locked in positions of adjustment upon the shanks 17 by means of cotter pins 19 which are adapted to engage alining perfor-ations 20 provided in opposite sides of the inner end portions of the members 18, said perforations being adapted to register with perforations 21 provided in the shank 17 as clearly shown in Fig. The outer end portions of the members 18 are formed with downwardly opening' recesses 22 which are adapted to accommodate or permit of the admission of the upper edge of the keg in conjunction withwhich the device is used. Outwardly projecting fingers 23 provided at the inner sides of the recesses 22 are adapted to engage the circumferential groove 24 which is provided within a usual paint keg at the respective extremities thereof, this groove being pro-vided for engagement with the periphery of the head of the keg when the latter is sealed.

\e5 Mounted upon the outer extremities of the arms 18 are cam members 25, the peripheries of the engaging portions of said cams which are circular in form being eccentric to the pivotal points 26 thereof, and so that upon proper rotation of said cam members the peripheries thereof will be brought into engagement with the outer sides of the keg to effect the secure clamping of the outer ends of arms 18 upon the keg. The cam members are operated by means of handles 27, spring detents or pawls 28 pro vided in the bifurcated ends of the handles 27 being adapted to engage with teeth 29 provided in the adjacent ends of the arms 18 to serve to lock the cams 25 in positions of adjustment. ith this arrangement it -will be seen that in fastening the device upon a keg it is only required after engagement ofthe fingers 23 with opposite sides of the groove 24k of the keg to swing the outer ends of the handles 27 downwardly until the cams 25 are forced into clamping engagement with the adjacent sides of the keg, the detents 28 automatically engaging the teeth 29 to lock said cams in position. When it is desired to remove the device the engaging ends of the detents 28 need only to be moved outwardly to disengagement, whereupon the handles 27 may be swung upwardly to effect release of the cams. The

adjustable connection of the arms 18 with the shanks 17 evidently renders the device applicable for use in conjunction with kegs of various sizes. Also formed at the lower end of the bearing member 8 is a. stud 30 which is disposed medially between the sha-nks 17. Rotatably mounted upon the stud 30 is a segmental gear 31, said gear being held in position by a cotter pin 32, a. washer 32 being interposed between said pin and the adjacent end of the hub of said gear. Said segmental gear meshes with a bevel pinion 33 which is formed integral with the bearing member 9 at the lower end of the tube 6. Projecting upwardly from the segmental gear 31 is a shank 34 adapted for engagement by the lower end of a tubular lever 35 as clearly shown in Fig. 3. The arrz ngement is such as will be observed that oscillation of the shaft 1 and hence of the dasher plate 2 is effected by oscillation of the lever 35, the oscillation of said lever being effected readily and easily by engaging the upper end thereof. By reason of the gear connection between the lower end of n lli/35 tached to a keg for use and as readily and expeditiously detached from the keg when desired. Y

By reason of the many adjustments afforded in the construction, the device is rendered applicable in conjunction with kegs of various sizes and proportions.

It will be clearly understood that the various elements of the present invention, such as the handles 37, may be folded inwardly and the remaining elements may be disconnected for the purposes of packing or storage when so desired, thereby economiaing space utilized.

1V hile I have illustrated and described the preferred forni of construction for carrying .my invention into effect, this is capable of variation and modification without departing from the spirit of the invention.
