AXEL C. BERNTZEN, OF EUGENE, GREGON.

AUTOMATIC CHICKEN-FEEDING MACHINE.

Specification of Letters Patent.

Patented Feb. 6, litri?.

Application filed February 9, 1915. Serial No. 7,202.

To all 'io/0m t may concern.'

Be it known that I, AXEL C. BERNTZEN, a citizen of the United States, residing at Eugene, in the county of Lane and State of Oregon, have invented certain new and useful Improvements in Automatic Chicken- Feeding Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to automatic chicken feeding machines and has for its principal object the production of a device which is so constructed as to intermittently distribute'a quantity of food carried thereby.

object of this invention is the Another production of a chicken feeding machine in which a number of cans are pivotally mount` ed so that when they are released they will independently swing downwardly for emptying the food carried thereby, said cans being provided with asimple means for intermittently releasing the same.

Another object of this invention is the production of an automatic chicken feeding machine wherein simple and efficient operating mechanism is provided for automatically swinging the trip arms for intermittently releasing the cans whereby the food positioned within the cans may be emptied therefrom.

With these and other objects in view, this invention consists of certain novel combinations, constructions, and arrangements of parts as will be lhereinafter fully described and claimed. Y

in the accompanying drawings:

Figure l is a matic chicken feeding machine as constructed in accordance with this invention.

Fig. 2 is a side elevation of the operating portions of the machinea portions of the device being broken away.

Fig. 3 is a section taken on the line 3 3 of Fig. 2 looking in the direction of the arrows.

Fig. L is a vertical section through a portion of the machine illustrating the manner in which the cans are supported.

Fig. 5 is a top plan view of the upper platform illustrating the manner in which the motor carried thereby, a portion of the cover plate being broken away.

Fig. 6 is a fragmentary detailed perspective view of the upper platform illustratside elevation of the autoing the manner in which one of the trip arms is supported.

Fig. 7 is a vertical sectional view one of the cans.

Fig. 8 is a detailed perspective view of a certain pivot bracket used for pivotally mounting the cans upon the device.

Fig. 9 is a fragmentary sectional view through the upper platform illustrating the manner in which the motor is carried thereby.

Fig. 10 is a top plan view of a certain drive wheel used in connection with this invention.

Referring to the accompanying drawings by numerals it will be seen that the automatic chicken feeding machine comprises a lower platform l and an upper platform 2. lThese platforms l and 2 are preferably made of wood. However, it is, of course, obvious that they may be made of any other suitable material. They are reinforced about their outer peripheries by means of the metallic bands 3 which efficiently reinforce the same and also reduce the friction thereon as well as the wear when the device is in use. The supporting standards d radiate toward their lower ends and are adapted to have their ends suitably secured to the lower platform l. The upper ends of the standards may fit into sockets formed in the platform l, so as to be quickly detached therefrom if desired. A plurality of curved fingers 5 have laterally bent ends 6 extending therefrom, these ends being secured in any suitable manner to the lower surface of the lower platform l, whereby7 the outer ends of the fingers pwill extend for a considerable distance beyond the plane of the outer peripheries of the lower platform l, as shown in Figs. l and 2.

A plurality of supporting rods 7 pass through the lower platform -1 and are secured in place by means of the nuts 8, whereby these rods 7 will extend for a considerable distance within the lower platform l ffor the purpose of retaining the upper platform l -in its correct position. These rods 7 are provided with heads attheir upper ends as shown at 9 in Fig. 5 whereby the upper platform is held against accidental displacement, and will, therefore, be retained in alinement with the lower platform l.

The hangerr b 1ackets il are carried by the lower portions of the upper platform 2 so as to extend for a considerable distance beyond the outer peripherics thereof, and these hanger brack- -tl are provided with upturned outer ends 42 whereby these brackets may support the hood 43 above the upper platform 2. Therefore, while this hood is detachably supported when it is car 1ied by the hanger brackets il it will protect the cans and upper platform from the weather when the device is used out of doors and will also prevent the fowls which may fly thereacross from accidentally engaging the trip arms and thereby cause the cans to accidentally empty the contents carried thereby.

`When this device is in operation the hood may be removed so as to allow the cans to be easily swung upwardly whereby the trip arms 2d may be swung` for engaging the plates 2l thereby releasably retaining the cans in their correct positions for retaining the cont-ents .carried thereby. The motor may be wound by means of the key 30 and then the cans may be filled. The hood may then be replaced upon the hanger brackets 41, at which time the device is in operation.-

It is, of course, obvious that the motor 29 may be geared so as to swing the trigger 33 as rapidly as desired, which is preferably about one revolution every eight or ten hours. As the trigger 33 comes into engagement with the trip arms, it will swing the same until the motion is limited by the adjacent pin 26. rlhe can being supported offcenter will swing downwardly, thereby emptying the food therefrom.

From the foregoing description it will be seen that a very simple and eflicient automatic chicken feeding machine has been produced, wherein the food carried by the cans will be easily emptied therefrom whenever the cans are released, whereby only a predetermined amount of food may be distributed for use.
