4 Claims.

This invention relates generally to drive mechanism for tools or the like and more particularly to drive mechanisms for devices for peeling potatoes and the like.

A primary object of the invention is to provide means for readily attaching and detaching a tool to the drive mechanism.

Another object is to provide means for securely holding the tool on the drive mechanism.

A still further object is to provide means for readily releasing the tool from the drive mechamsm.

My invention Will be better understod from the description thereof to follow taken in connection with the accompanying drawings in which- Figure 1 is a view partly in elevation and partly in section of my improved device.

Figure 2 is a front view of the tool mounting and driving mechanism with protecting hood thereover.

Figure 3 is a rear view of the mounting mechanism shown in Figure 2.

Figure 4 is a detail view showing the tool holding or clamping device.

Figure 5 is a side elevation of a potato peeler, one form of tool adapted to be used with my improved device.

Figure 6 is a sectional view of part of the peeler shown in Figure 5.

Figure 7 is a detail view showing the hood and holding means.

Figures 8 and 9 are a side elevation partly in section and an end view of a grater, another form of tool adapted to be used with my improved device.

Figure 10 is a side elevation partly in section of a grater similar to the grater of Figure 8 but having finer cutting edges.

Figure 11 is a sectional view of a tool for cutting potato adapted to be used with my improved device.

Figures 12 and 13 are side of another form of potato peeler.

Figures 14 and 15 are side and end elevations respectively of a tool for reaming oranges and the like.

Figures 16 and 17 are a front elevation and a sectional view respectively of a buffer and the I like, another form of tool adapted to be used with my improved device.

My improved mechanism may be mounted on a base or other support 20. A'stand 2| is fastened'to said base and an electric motor 22 is secured to a cradle portion on the upper end of and end elevations the stand by means of a bolt 23 passing through lugs 24 and the upper end'of the stand.

A pinion 25 is mounted on the outer end of the motor shaft 26. 1

Secured in a bushing 21 in the upper, portion of the motor casing is a hanger shaft 28 which extends outwardly in front of themotor casing. Loosely mounted on the outer end of this hanger shaft is a gear wheel 29 hereinafter called the power gear wheel. A nut 39 keeps this power gear wheel on its shaft, and when on the shaft it is in line with and on the motor shaft 26.

- .On the outer face of the rimof this power gear wheel at spaced intervals are stationary pins or studs 3|, and mounted rotatably on'said rim at points between the stationary pins 3!. are. pins or. studs 32. All of these pins are on the same circular plane. The stationary pins3l are beveled in shape, the thicker portion thereof being on the inner end.

Each of the rotatable studs 32 extends through meshes with the pinion 25 the rim of the power gear wheel and carries on its inner end a pinion 33 positioned close to the inner face of the rim of the power gear wheel.

'On the outer end of each of said rotatable studs 32 is'a cross piece or finger 34..

drive any sort of a cylindrical tool. For illus-' tration, in Figure 1 a tool for peelingv potatoes is shown on the machine. This tool comprises a cylindrical body portion 35 having an open end in which is a ring member 36, hereinafter called a power ring. This power'ring may be formed integrally withthe body portion or may be a separate ring mounted on the studs 3| and 32 or may be fastened the inside of therim- The power ring has a beveled body portion, with its thin edge positioned near the open edge of the cylindrical body portion, and its thick edge on the inside. The body portion is formed with projecting cutting edges 31 running lengthwisethereof and spaced from each other. Formed on' the body portion in the'space-between the cutting edges 31 are protuberances 38. Preferably two rows of these protuberances running lengthwise of the cylinder and disposed in staggered relation are used. The closed end of the cylinder is formed with a bulged blades 46. rounded.

Loosely mounted on the hind the power gear wheel 29 is a master gear wheel 42. This gear Wheel 42 is in constant mesh in any suitable way tohanger shaft (23 b with the pinions 33 on the revolvable' studs 32. A hand lever 43 secured to one of the pinions 33 is adapted to operate the master gear wheel 52 and the other pinions 33.

The tool, for instance the potato peeler described, is mounted in operative position by sliding the beveled portion of the ring 38 over the beveled stationary studs 3|. To securely hold the tool on the studs 3 I, the lever 43 is moved, which movement rocks the cross heads or finger pieces 35 into engagement with the broad edge of the power ring 36 thereby jamming said ring onto said studs and holding the same against displacement. To release the tool and permit its detachment from the studs, the lever 43 is moved in the opposite direction.

In operation, electric motive force is supplied to the motor 22 from any suitable source by means of the conductors M. A switch may be provided at any point in the circuit as is customary. l/iovement of the motor shaft 26 is imparted to the power gear wheel 29 through the pinion 25, This wheel 29 carries the tool, which is mounted on the studs 3i, around with it. The potato or other article is presented or fed to the cutting edges 31 and protuberances 33 by hand. The protuberances scratch the skin and the cutting edges 31 which are a trifie higher than the member 38 scrape off the skin. The bulged out portion 39 of the potato peeler cuts out the eyes or other defects in the potato. The rounded corner 4! of the potato peeler helps to cut off the skin in all declivities and irregular shaped portions of the potato.

A guard housing or hood may be provided to prevent the food from scattering. This guard is shown as detachably mounted on a frame 46 secured to the motor casing by means of'screws 41. One form of means for holding the guard on the frame is shown in Figure '7 as comprising a key member 48 fixed to the housing 45 and extending laterally therefrom. This key 48 v is adapted to enter a barrel member 49 fixed to the rear of the frame 46 through a slot in the frame.

The housing '45 is provided with a hopper opening 50 for feeding articles of food or the like downwardly against the tool by gravity or by hand pressure as desired. A block 5| having a knob 52 may be provided to snugly fit the hopper opening and force the food downwardly into contact with the cutting tool.

In Figure 8 the tool is shown in the form of a grater 53 having staggered protuberances 54 with cutting edges. A beveled ring 55 is fixed to the interior of one rim thereof.

The grating tool shown in Figure 10 is constructed similarly to the tool shown in Figure 8 but the protuberances 56 are finer.

The tool shown in Figure 11 is for cutting potato chips and comprises a cylindrical body portion similar to the graters shown in Figures 8 and 10, but has projecting knife edges '5'! spaced from each other and openings 58 in front of each knife edge leading to the interior of the body portion. Figure 12 illustrates another form of potato peeler and comprises a cylindrical body portion having cutting edges 59 and protuberances 60 between the cutting edges. A bulbous portion 6| extending from one end of the body portion and having blades 62 provides areamer for extracting foreign matter from the potato. This form of peeler is provided with the ring member 36 for mounting on the drive mechanism.

In Figures 14 and 15 a form of tool for reaming oranges is shown. It comprises a bulbous portion 63 having curved blades 64 terminating at a common point. The mounting ring 36 is secured to the interior of the open rim of the body portion.

A tool in the form of a buiTer (i5 is illustrated in Figures 16 and 17. This buffer is shown as a disc 66 comprising layers of fabric or other suitable material secured between a ring 61 and a plate 68. Bolts 69 passing through said ring 61 and plate 68 and a flanged finishing ring l0 hold the parts together. The wall of the opening in ring 32 is beveled for mounting on the beveled stationary studs 3| of gear 29.

7 Each of the forms of tools illustrated in Figures 8 to 1'7 inclusive is mounted on the stationary studs M of gear wheel 29 by means of the beveled ring secured to a rim of the body portion of each of said tools as will be understood.

Changes in details might be resorted to and parts of the invention may be used without others without departing from the principle of the in vention.
