FRANK A. WOOL AND WILLIAM"`BOHLIN, OF NEAR SAN JOSE, CALIFORNIA@ CANNINGr MACHINERY.

Application filed September WLLLIAM BOHLIN, citizens of the Unitedv States, and residing, respectively, near San J ose, in the county of Santa Clara. and State of California, have invented certa-in new and useful Improvements in Canning Machinery, of which the following is a specification.

It is one object of our invention to provide a simple automatic device for feeding cans at spaced intervals from one mechanism to another.

It is another object of our invention to provide a device of the character indicated that will space the cans accurately without injury thereto and without spilling the contents o-f the can if the can be open.

It is still a further object of our invention to provide a device of the character indicated that will be simple in form and construction, economical to manufacture, positive in action and highly eiiicient in its practical application.

In the drawing Figure 1 is a plan view of the device.

Figure 2 is a section on line 2-2 of Figure 1. Y

Figure 3 is an enlarged detail of one of the carrier arms and the mounting therefor.

In the embodiment of the invention herein disclosed we show the device used in conjunction with a cooker, a portion of which is indicated at 17 2 being one of the transfer gears therein, and an endless chain 3 provided with upsta-nding lugs 4 for carrying the cans to the capper not shown.

At 5 is shown a transfer platform, semicircular in plan and supported on a level with transfer gear 2 and chain 3 by any suitable means not shown, the same being continued along both sides of chain 3 as shown at 6.

A guide rail 5 is mounted on the outer edge of platform 5 by supp-erts 7 and eX- tends from the cooker around the said platform and along the outer edge of parts 6. A second rail is provided at 8 to guide the cans to the transfer device, and a third rail is provided at 9 to insure the passage o-f the cans squarely on to chain 3.

On any suitable support is mounted a vertically disposed rod 10 carrying a head 11 upon which is revolubly mounted a plate 12 by means of bearing 13. Plate 12 lies in a horizont-al plane with its upper surface Hush 13, 1923. Serial No. 662,534,1-

with the upper surfa-ceaof. platform :5, andfi'sr circular in aplan,A its :edge `closely approaelr. ing but not touching the inner edge of plat-- form 5.

Spaced equally about the upper surface Y of plate 12 and arranged radially thereon are a plurality of pairs of upstanding lugs 1li, each pair of lugs having a rod 15 slidably mounted therein. On each rod 15 and between the lugs 14 through which it passes is a coiled spring 16. A pin 17 is inserted in each rod 15 inside of the outer lug 14 to receive the thrust of the spring thereon, and a second pin 18 is inserted in each rod on the outer side of the inner lug. By means of this arrangement the rod is normally held in an extended position as sho-wn whereby it will pass over the platform 5 and engage a can thereon, but will readily slide inwardly against the outward pressure of spring 16 if pressure `is applied to its outer end.

The lugs a on chain 3 are spaced to engage the ends of the several rods 15 in succession thereby rotating the plate 12 in the direction indicated by the arrow, the movements of the chain 3 and gear 2 being synchronized so that the cans are removed from the platform 5 at the same rate of speed that they are fed thereon.

Assuming the gear 2 and chain 3 to be in operation and moving in the direction indicated by the arrows the action of the device is as follows:v v

A' can 19 carried forward lby gear 2 contacts with rail 5a and is urged outwardly onto platform 5 where an arm 15 engages it and pushes it around onto chain 3 where it is engaged by a lug 4L and carried forward to the capping machine.

Since the cans on gear 2 are not spaced but are carried along singly or in groups in which one can contacts with another, it sometimes happens that a can is pushed on to platform 5 with an arm 15 pressing against its inner side instead of behind it. In this case the arm is pushed inagainst spring 16 as indicated in dotted lines at 20 until the movement ofthe can causes it to slide ofi its rounded side, whereupon the spring again returns the rod to its normal position. i

In this manner the cans are properly spaced for feeding onto carrier chain 3 without danger of injury or spilling of their content-s. lVhere fixed rods or arms of anv kind are used the feeding is not accomplished Without occasional injury to cans and loss, or partial loss, of their contents.

It is to be understood, of course, that While We have herein sho-Wn and described one specific embodiment of our invention, changes in form, construction and method of operation may be made Within the scope of the appended claim.

We claim:

A can transfer device comprising a plate and means for rotating the same, a plurality of radially arranged pairs of stops mounted on said plate, a spring inserted between each pair of stops, a rod extending through each pair of stops and the spring therebetween, and spring engaging means Carried by each rod whereby to compress the spring thereon when moved toward the center of said plate.
