CAN-WASHING MACHINE."

T 0 it mag concern:

Beit known that I, CHARLES F. MOEVAN, a citizentof'the United States, and a resident of the city of Oak Park, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Can-Washing Machines, of which the following is a specification.

My invention relates-to improvements in can washing machines, and has for its object the provision of improved means for lessening the noise and shocks of the operation thereof.

Other objects will appear hereinafter,

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

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

Figure 1 is a side view of the discharge end of a can washing machine embodying my invention.

Fig- 2 is a partial view correspondlng with Fig. 1, but'showing the parts in dif ferent positions.

Fig. 3 is a partial top plan View of the device;

The preferred form of construction, as illustrated in the drawings, comprises the usual reversing and discharging saddle 4:, pivoted at 5 in the frame of the machine and connected by a link 6 with the upper end of a lever 7. The lever 7 is inturn connected by a link 8 with a-rocker arm 9 on a I fork 12, and it will be noticed that continued motion of the roller 13 to the. right will cause rocking of the arm 11, and consequently of the shaft 10 to operate the saddle 4 in the usual manner. During this operation the fork 12 will remain in constant engagement with the roller 13, thus preventing overbalancing and gravity operation of the Specification of Letters Patent.

saddle 1 to. violently invert and discharge the can, thus preventing shocks and jars and lessening the noise of theoperation of the machine. i

The machine-is operated through periodical horizontal reciprocations of the operat- 111g bar '14; which serves in the usual manner to feed the cans. through the machine in inverted positions, depositing one of said cans in the saddle 1 at each movement of said bar. At the time of the deposit of each can in said saddle, the roller 13 is just in the fork '12 as indicated in Fig. 2. Further movement of the bar 14 causes said roller to travel.

in said fork rocking the arm 12, and inverting and discharging the can as indicated in Fig. 1. At the end of its rocking motion the saddle 4:, still carrying the can, has a tendency to continue its motion under the force of gravity and the inertia or momentum of the parts so that, unless restrained, the can will be delivered with great force and violence causing considerable noise and injury to the can. This continuation of the movement of the saddle 4 and the contained can is restrained and prevented by the engagement of the fork 12 with the roller 13 preventing the same. Thus the can will be delivered gently and without undue noise or injury thereto.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of the construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A can washing machine, comprising can moving means; means engaging and disengaging said moving means for operating the same; and means for holding said operating and moving means in engagement during the operation of the latter, whereby con tinued operation of the latter under its own inertia is prevented, substantially as described.

2. A can washing machine, comprising can reversing and discharging means; means engaging and disengaging said reversing and discharging means for operating the a horizontally reciprocating operating bar; 20

same; and means for holding said operating means and said reversing and discharging means in engagement during the operation of the latter, whereby continued operation of the latter under its own inertia is prevented, substantially as described.

3. A can washing machine, comprising a can reversing and discharging saddle; a rocker arm arranged to operate said saddle; a reciprocating operating bar; a roller on said bar; and a fork on said rocker arm arranged to engage and disengage said roller and hold said rocker arm in engagement with said roller during operation of said saddle, substantially as described.

4. A can washing machine, comprising a can reversing and discharging saddle; a rocker arm arranged to operate said saddle;

a roller on said bar; and a fork on said rocker arm arranged to assume horizontal position to engage and disengage said roller, said fork being of sufficient length to permit of movement of said roller within said fork and arranged to assume substantially vertical position at the termination of move ment of said saddle, whereby continued operation of said saddle under its own inertia is prevented, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES F. MoE /VAN.
