SEEIFICATION forming part of Letters Patent No. 668,100. dated Feblualy 12, 1901 Application tiled November 12, 1900. Serial No. 36,253. (No modela Be it known that I, CHARLES HILBERT, a citizen ofthe United States, residing at Cincinnati, in the county of I'Iamilton and State of Ohio, have invented certain new and useful Improvements in Driving Mechanism for Ice-Cream Freezers, of which the following is a specication.

The object of my invention is to provide a power device for driving the flasher-shaft and can of an ice-cream freezer in opposite directions, with the devices so arranged that the driving-shalj'ts maybe elevated, leaving the can and freezer portion free for removal with ont disturbing the relative arrangements of the driving devices.

The features of my invention are more fully setforth in the description of the accompanying drawings, forming a part of this specification, in which- Figure l is a central vertical section, partly in elevation, of my improvement in position for use. Fig. 2 is a central vert-ical section of parts of Fig. l, showing the shafts in their elevated position. Ilig. is an enlarged vertical section of the driving-shafts, their gears, and the elevating mechanism. Fig. et is an enlarged section on line a' at', Fig. l. l

A represents the supporting-base, upon which the freezer-tub B is supported. C represents a standard erected on said base.

d represents a means projected from the standard for engaging and holding the tub.

o represents a stud projected from the standard, upon which is a sleeve-shaft c. The said sleeve-shaft supports a fly-wheel d, fast and loose pulleys e e', and a spur-gear f, the flywheel, fast pulley, and spur-gear being' fixed to turn with said sleeve-shaft. D represents a shaft journaled in the standard above the said sleeve-shaft and substantially parallel therewith, having iixcd to its outerend a spurgear g, meshing with the s1;iur-gearfon sleeveshaftc. On the opposite end of shaft D is a bevel-gear h. The upper end of the said stan dard is curved over the supporting-base and terminates in substantially if-shaped joui'- nal-arnis the upper limb 7c of which forms a journal-bearing for the bevel-gear t' and the lower limb Z forming a journal-bearing for the bevel-gearj, said gears being in mesh with the bevel-gear @whereby they are revolved in opposite directions. The bevel-gearj is feathered and splined to a sleeve-shaft fm, revolving in the journal-bearing Z. The lower end of sleeve-shaft m is provided with a socket/1L.

E represents the ordinary freezer-can jou rnaled in the tub B and provided with a topE.

o represents a boss or stem projected from the can-top, which lfits the socket n of the sleeve-shaft on. NVithin this sleeve-shaft on is a shaftp, feathered and splined to the bevelgear z', the lower end of this shaft being provided with a socket q, which fits the boss fr' of the flasher-shaft s, projected through the boss oi' the can-tcp.

The sleeve-shaft m has an internal offset t, and the shaft p has a shoulder u bearing against the saine, so that when the shaft p is raised it raises with it the sleeve-shaft fm.

In order to lift the two shafts m p, respectively, from the can-top, I provide the following instrumentalities; F represents a sleeve seated on the upper limb 7a of the standard and around the upper end of the shaft p. It is provided With a worm groove or slot G. H represents a stud on the shaft p, projected into said worm-groove. I represents a hand-wheel attached to the top of said sleeve F. It will be observed that the groove is inclined in the direction reverse to the direction o'l' revolution of the shaft p, so that the stud on said shaft will bear against the lower extremity of the groove when the shaft is revolved and carries said wheel with it in its revolution. When it is desired to lift the driving-shafts, however, the handwheel is turned in the same direction and the stud on sh'aft p will travel up the incline and into the straight end of the incline II, which forms a rest, thus lifting the shafts p fm, which slide respectively through their bevelgears t' j and free their sockets, respectively7 from the dasher-shaft and can-top. The can is thus permitted to be taken from the tub without in any wise disturbing the arrangement of the driving parts. It will be observed that the upward movement of the said shafts is represented by the opposing faces of the bevel-gears t' j; but this is suiiicient to provide space for the removal of the can or tub.

Having described my invention, I claiml. The combination in a power device for ice-cream freezers of a standard, right and IOO left hand bevel-gearsjournaled one abovethe other o'n the standard, a sieeve-shaft splined to the lower gear and adapted to be socketed to the can-top, an internal shaft splined to the upper gear and adapted to be socketed to the flasher-shaft, the said shaft being offset into the sleeve-shaft, whereby they will both be raised with the internal shaft, a sleeve mounted o n the internal shaft above the journaled support for the upper gear, a worm-groove formed in the said sleeve, a projection on the internal shaft vengaging into this groove, and a hand-wheel on the said worm-sleeve adapted to raise the said shaft, substantially as specified.

2. The combination in 'a power devicefor ice-.cream freezers of a standard, right and left handl bevel-gears journaled one above the other on the standard, asleeve-shaft splined to the lower gearz and adapted to be socketed to the can-top, an internal shaft splined to the upper'k geary and adapted to be socketed to the dasher-shaft, the saidshaft being offset into thesleeve-shaft, whereby they Will both be raised with the internal shaft, a sleeve mounted on the internal shafty above thev journaled support for the upper gear, a worin-groove formed in the said sleeve, in a direction of inclination the reverse to the esame direction o f rotation of the said shaft, a projection of the internalI shaft engaging into this groove, and a hand-wheel on the said worm-sleeve adapted to raise the said shaft, substantially as specified.

3. I n combination with a power device for ice-cream freezers, a standard, right and left hand bevel-gears journaled thereon, a sleeveshaft and anl internal shaft splined respectively to the said gears and adapted to be socketed respectively to the can-top and the dashershaft, said shafts being adapted to be raised in unison, the internal'shaft projected upwardlythrough the sleeve-shaft and having a projection thereon, a worm-sleeve journaled around the upper end of said internal shaft having a groove inclined in a direction reverse to the rotation ofthe yshaft which receives thel said-S projection in the shaft, the said groove terminatingv in a straight horizontal plane forming a; rest forA the internal shaftwhen itis raised, and aWorm-wheel on the sleeve, substantially as speciiied.

In testimony whereof I have hereunto set my hand.
