CHURN AND BUTTER-WORKER.

Specification of Letters Patent. Patented Mar. 22, 191%.,

Application filed January 11, 1909. Serial No. 471,798.

This invention relates particularly to churns and butter-workers of the type comprising a drum rotatably supported at its ends. Such drums are liable to distortion from various causes.

' In the constructions commonly used at the present time the distortion just referred to injuriously affects the bearin s for the drum, throws the drum out o proper relation to its driving mechanism, and may throw the parts of the driving mechanism It is one of the objects of this invention to provide im-- out of proper position.

proved bearings for the drum or body of the churn or butter -worker, which L shall properly support the body notwithstanding the latter may become somewhat distorted.

Another object of the invention is to provide an improved driving means for churns and butter-workers.

In the accompanying drawings, Figure 1 is a front end elevation of a combined churn and butter-worker embodying the features of my invention. Fig. 2 is a rear elevation thereof. Fig. 3 is a vertical central section through the machine, parts being broken away to shorten the view. Fig. 4 is a detail sectional view of thevrear end bearing for the drum. Fig. 5 is a top plan view of said bearing.

The frame of the machine, in the present embodiment, comprises the front end frame land the rear end frame 2, said end frames being rigidly secured together by means of rods 3 extending through distance tubes 4. It will be understood, however, that the particular construction of the supporting framework is not material to the invention.

The drum or body 5 consists of the cylinder 6 and heads 7 and 8. As herein shown, the drum is supported at its ends. To the rear head 8 of the drum is fixed a gudgeon 9 which is supported in a bearing that is free-to oscillate in vertical and horizontal planes. In the construction herein illusthe end frame 1.

| trated a cage or frame 10 is secured in the rear end'frame 2 by means of bolts 11 extending through the portion 12 of said end frame into the base of said cage. The latter may be adjusted in height by placing spacing plates between said cage and the portion 12 of said end frame.

13 is a bearing block which may be atwopart construction, as shown in Fig. 2-,'said bearing block receiving the gudgeon 9 and being mounted in the cage or frame 10. Upon its lower side, the bearing block 13 has a frusto-conical stud 1 1 (Fig. 4) which is pivotally mounted in a socket 15 in the cage-10. The side walls of said socket are tapered at a greater angle than the stud 14 in order to permit said stud to rock in said socket.

Upon the upper side of the bearing block 13 is a lug 16 which lies within a groove 17 in the cage 10. As shown in Fig. 5, the side walls of said groove are straight, while the sides of the lug 16 are rounded to permit the bearing block 13 to rock in a horizontal plane. As indicated in Fig. 4, the upper end of the lug 16 is rounded to permit the bearing block 13 to oscillate in a vertical plane.

18 are screws seated in the cage 10 at opposite sides of the groove 17 the inner ends of said screws being arranged to lie at opposite sides of the lug 16. Said screws provide means for taking up any wear that may occur upon the lug 16 and the walls of the groove 17. and thus prevent side motion of the bearing block 13. The screws 18 may be locked in adjust-ed position by means of the lock nuts 19.

Referring now .to the front end bearing, as illustrated in Fig. 3: 20 is a sprocket wheel having a hub 21, one end of which hub is rotatably mounted in a bearing. 22 in The other end 21 of the hub 21 is adapted to support the adjacent end of' the drum 5. Upon the drum head 7 is fixed a spider having a central bearing 91 to receive the hub 21 of the sprocket wheel 20. The walls of said bearing are convex, as shown, in order that theside bearing -1nay rock upon the hub 21*. A driving engagement between the drum 5 and the sprocket wheel 20 is effected by suitable means, as, for example, lugs 25 upon the spider 23, fitting within recesses .supported near one end in abearing 30 in said bracket and carries upon its outer end a drive pulley 31. A hub 32 is rotatably mounted in a bearing 33 in the end frame 2 and rotatably supports the inner end of the drive shaft 29. Fixed to said hub is a sprocket wheel 34 to receive a chain (not shown) extending over the sprocket wheel 20. In one end of the hub 32 are formed recesses 35 to receive clutch teeth 36 upon a pinion 37 that has a spline connection with the drive shaft 29 and 1S slidable longitudinally of said shaft. When the pinion 37 is clutched to, the hub 32 as shown in Fig. 3, power is communicated directly from the pulley 31 through the shaft 29, the pinion 37 and the hub 32 to the sprocket wheel 34 for rotating the drum,as during the churning operation.

When the butter is to be worked, it is desirable to rotate the drum at a lower speed than that used for churning. To this end, I have provided back gearing comprising a gear wheel 38 fixed upon a shaft 39 that is rotatably mounted in bearings 40 and 41. in the end frame 1 and the bracket 26, respectively. Said gear wheel is arranged to mesh with the pinion 37. Upon the shaft 39 is fixed a pinion 42 that meshes with a spur gear wheel 43 which is rotatably mounted upon the hub 32. The means for clutching the gear wheel 43 to the hub 32, in this instance, is arranged to operate automatically upon the disengagement of the pinion 37 from said hub. 44 are keysslidably mounted in the hub 32, and adapted to engage in recesses '45 in the spur gear wheel 43. Springs 46 tend to move the keys 44 into engagement with the gear wheel 43. One end of each of the keys 44 is arranged to extend into a recess 35 when the opposite end is within a recess 45. It will be seen that when the inion 37 is moved into clutch engagement wlth the hub 32 the teeth 36 on said pinion push the keys 44 inwardly to uncouple the spur gear wheel 43 from the hub 32, and that when the pinion 37 is slid away from the hub 32 the springs 46 automatically move the keys 44 to connect the spur gear wheel 43 with the hub 32. The pinion 37 may be slid longitudinally of the drive shaft 29 by suitable means such as afork 47 provided with an operating arm 48 (Fig. 1).

The butter working mechanism includes two shafts 49 extending longitudinally of and journaled in the drum 5 and bearing upon their outer ends intermeshing gear wheels 50 and 51. The gear wheel 51 meshes at all times with a gear wheel 52 fixed upon the inner end of a shaft 53 which is journaled in the hub of the sprocket wheel 20 andin a bearing 54 in the bracket 26. The shaft 53 is driven only during the butterworking operation.

Rotatably mounted upon the shaft 53 is a pinion 55 that meshes with the spur gear wheel 38 upon the shaft 39. Slidably supported upon the shaft 53 is a clutch member 56 having a spline connection with said shaft, said clutch member being adapted to engage the hub of the pinion 55 to clutch the shaft 53 to said pinion when the butter Working rolls are to be rotated. 57 is a hand lever for operating the clutch member 56.

In use, distortion of the drum heads or the cylindrical walls of the drum will not interfere with the proper operation of the machine. The bearing block 13 is free to oscillate invertical and horizontal planes with relation to the cage or frame 10, and the bearing 24 likewise is free to rock with relation to the hub 21. It will be seen that the driving mechanism is not rigidly connected to the drum, the latter being free to move slightly with relation to the sprocket wheel 20. The shafts 29, 39 and 53 being mounted in a rigid framework and being yieldingly I the drum and can not get out of alinement with one another.

I would have it understood that I do not limit myself to the details of construction herein set forth, for various modifications will occur to persons skilled in the art.
