tion.

My invention relates to an improvement in tumbling barrels of that class known as tilting tumbling barrels and the object of my improvement is to provide a device which will be easier to operate than heretofore, more effective and of greater durabilit Y. I obtain these objects by the means il ustrated-in the accompanying drawings which show one way of carrying out my 1nvention, the features thereof being ancre particularly pointed out hereinafter in the claims.

In the drawings, Figure 1 is a side elevation of a device illustrating my invention, parts -being broken4 away and parts being lshown in section. Fig 2 is a plan View of the same with the upper half of the housing removed, parts being broken away and parts beingshown in section, and Fig. 3 is a sectional view along the line 3, 3 Fig. 2, with the -upper half of the housing attached.

Similar numerals of reference indicate similar parts throughout the several views.

1 indicates the bed plate supporting standards 2, 2.

3 is the driving shaft mounted in bearings 4, el on standards 2, 2, said shaft being driven by any suitable means, such as fast and loose pulleys 5 and 6 respectively.

7 is a worm shown here as keyed to shaft 3.

S is the driven shaft on the-end ofwhich is secured the hu-b S) of plate o r support 10.

11 is a key locking hub t) to shaft 8. Ilate 1() carries barrel 12 which is preferably formed of wooden stripsor staves 13 secured together' in any desired manner. Barrel 12 may be provided with a. brass lining 14 extending from the bottom of the barrel upward to any desired distance, as shownln Fig. 1. Shaft 8 carries a Worm wheel 15 secured thereto by key 16, said worm Wheel 15 being adapted to mesh with and be driven by worm 7 on shaft 3.

17, 17, 17, are suitable bearings for shaft 8, preferably of soft metal such as die cast Babbitt bearings, andconsequently interchangeable, and 18 isa ball-bearing adapted to act as a. thrust-bearing for shaft 8 and its load. Said bearings 17 and 18 are in turn supported in a housing, here shown as in three parts 19, 19, 15)". the bearings being held in position inthe housing by suitable lugs (not shown). The upper part 19 of the housing is removably secured to the intermediate part 15) by screws 20 and the lower part 19h of the vhbusing is removably secured to the intermediate part 19 by screws 20,

21 is a cap closing the end of the housing. The housing with cap 21 is adapted to completely inclosc shaft 8, worin 7, worm wheel 15 and bearings 17 and 18. Hubs 22 are formed in parts 19 and 19" of the housing,

as shown in Fig. 3.

23 is a toothed segment mounted on and preferably cast witlrthe intermediate portion 19 of the housing.

24; is a crank shaft mounted in standards 2, 2, carrying at one end a pinion 25 and at the other end a crank handle 26.

27 is a ratchet fast on standard 2. Crank handle 26 is pivotally mounted on the end of shafty 21 and carries a tooth or pawl 28 adapted to take into the teeth of ratchet 27.

2t) 4is a collar fast on the end of shaft 21 and forming a seat for spring 30 adapted to bea-r against the end of crank arm' 26 to normally throw pawl 28 into engagement with ratchet 27.

3l is a cross shaft carrying gear wheel`32 adapted to mesh with and be t riven by pinion 25. lross shaft 314 also carries a pinion 33 adapted to mesh with the teeth of segment 23.

34, 34 are suitable washers, preferably of wood ber, loosely mounted on shaft 3 between steel washers 34 and 3l", washers 34 being fast to worm 7 and washers 3l being fast to hub 22.

35, 35 are sleeves on shaft 3 extending as a center.

In the operation of the device,barrel 12 having been filled with the articles to be tumbled, the power is turned on driving shaft 3, which through Worm 7 and Worm wheel Acauses the barrel :to rotate at any l closing said barrel rotating vmechanism and desired speed. 'hen it is desired to tilt the barrel, crank arm 2G is moved away fronl the standard so as to release Apawl 28 from ratchet 27 and shaft 24 is rotated by means of crank arm 26; the rotation of ,the shaft through pinion `25, gear wheel 32 and pinion 33 on cross shaft 31,` causing segment 23 to be raised or lowered, carrying with it the barrel and its connecting parts, the housing being tiltedwith the shaft SA by having its trunnions movable about the driving shaft 3.

The housing may be packed with a suitable lubricating material, preferably a nonluid oil, in which the shaft S, worm 7 and worm wheel 15 turn, thus protecting them from wear and dust while permitting them to Work smoothly and easily and with less vibration than heretofore. The ball-bearings 18 and washers 34 assist in ease of operation and lessen wear.

36, 36 are oil cups in the top of hubs 22 i within the housing having oil holes 37 eX- tending through sleeves 35 to shaft 3, the shaft being provided with suitable oil channels (not shown) whereby the shaft and its bearings may be lubricated. Oil holes 38 on the under side of sleeves 35 permit the oil to reach bearings 4, thus lubricating them;

It is obvious that the details of arrangementand construction may be varied without departin .from the spirit of my invention. It is further obvious that the brass lining. 14 may be cast in one piece and may be made renovable, the barrel being, in such case, made of the same diameter throughout, as shown in the drawings, to provide for the easy slipping in and removing of the lining. Such lining not only protects and preserves the wooden portion of the barrel'but makes the Work of polishing much quicker as it gives a contact of brass on brass, where brass objects are those being tumbled.

lVhat I claim and desire to secure by Letters Patent is:

1. In a tumbling barrel, a barrel rotating mechanism, comprising a driving shaft, a gear thereon, a driven shaft on which the barrel is mounted, and a gear wheel onsaid driven shaft operably connected with the gear on the driving shaft, combined with means for tilting the barrel and its supporting and operating' shaft and its attached gear wheel, and a housing completely in- Worm thereon, a driven shaft on which thefga barrel is mounted, and a worm wheel on said driven shaft inmesh with the worm 011 the driving shaft, combined with means for tilting the barrel and its supporting and operating shaft and its attached worm wheel, and a housing completely inclosing said barrel rotating mechanism and movable therewith in the tilting movements of the barrel. y

3. In a tumbling barrel, a barrel rotating mechanism, comprising a driving shaft, a worm thereon barrel is axially supported, a worm Wheel on said driven shaft in mesh with the worm on the driving shaft, combined With means for tilting the barrel and its attached driven shaft and Wormwheeha housing completely inclosing said barrel rotating mechanism and movable therewith in the tilting movements of Vthe barrel, and a ball bearing thrust bearing for said driven shaft mounted in and protected by said housing.

4. In a tumbling barrel, a barrel rotating mechanism, comprising a driving shaft, a driven shaft on which the barrel is axially a driven shaft on which the mounted, and gearing connecting said shafts, e

combined with a housing completely inclosing said barrel' rotating mechanism, and means for tilting the barrel and its attached driven shaft and said housing, comprising a segment mounted on and carried by said housing, a crank shaft, a pinion `on said'A crank shaft, a cross shaft, a gear on said cross shaft meshing with said pinion, a pinion on said cross shaft meshing with said segment, and means for locking said crank shaft to hold the barrel in its tilted positions.

5. In a tumbling barrel, the combination with la barrel of the same diameter throughout, ofa removable one piece lbrass lining.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.
