I useful. Improvements in Stock-Feeders, of
which the following is a specification.
7 My invention relates to stock feeders for automatically feeding stock by the pressure of the animals nose against a portion or the feedingmechanism. j v
he objects of my invention are; First, to provide device of thisclass'which is simple and economical of construction, durable, easily installed and does not readily get out of order-;,second, to provide a device of this class in which, when a certai n quantity of food ,isvin the trough it will automatically stop the feed.
;l /Yith these vand other objects in view as will appear hereinafter, my invention cons'ists ofcertain novel features of construction,- combination and arrangement of parts as will be hereinafter described in detail and particularly set forth in the appended claims, reference being'i had to 'the accompanying drawings and to the characters'of reference thereon which form apart of this specification; in which Figure 1, is a sectionalview of my feeder 1 shown in connection with a fragmentary portionof a; feed hopper, and Fig. 2, is'a frontelevational view thereof. 7
Similar characters of referencefrefer to similar parts throughout the several views.
The' ybini 1, spiral 2, shaft 3, clutch piece 1, lever 5, link 6, clutch collar 7 feeding spider 8,- ratchet'wlieelafii, ratchet pawl 10, shield 11 and brace 12 constitute the principal parts of my stock feeder.
The bin 1 may be any shape desired and in the lower end is provided an aperture 1 and a cylindrical piece 1 adapted for the spiral 2 to revolve therein. From the inner edge of this cylindrical piece 1 is a slanting partition 1 adapted to conduct the feed in said bin to the exposed end of this spiral 2. On the other side of the bin 1 is provided a slanting portion 1 upon which is mounted a bearing 1 adapted for a bearing for one end of the shaft 3. The other end of said shaft is supported by means of the brace 12 which acts as a support for said shaft and is pro- Application filed February 1, Seriai fie. 2i4,8
I Specification of Letters Patent- Patented liiig; 27, 191 8 Which isadapted to eon duet the feed item the'bin 1 out through the. cylindrical piece to the trough 1 with, the revolution of saidspiral; Secured to the; outward end of the shaft just insidethe heating 12?- is a ratehet wheel 9 which ei igag'es with the ratchet pawl 10' whichi's pivotally mounted iliiinediately above said shaft on the brace 12 soth'a't itengeges with theeteeth in said ratchet wheel so that when said ratchet wheel tuiiied in one direction, the ratc lietfpawl engag s with its teeth and holds it in its turned osition, Revoli'ibly inoiiiited, on this Shaft, adjacent this ratchet wheel, isthe spider s which is prov'ide'd with a plur alit'y' of arms; 8EL extending radially therefrom. This; spider s is' prfoyided with hiib 8 which is provided with a plurality of lugs 8 which have faces perpendicular to the face of said hub on one side, and aiigled rates on the'pppesit side. Slidably mounted on the shaft 3" and provided with a key 4, is a clutch piece 4 which is rovided withhotehe's conforming to, and adapted to engage with the lugs 8 on the hub 8 when said clutch piece tisin the proper relative position to saidhub iece 8". This clutch piec 4 is provided with n annular groove 4} adapted for the collar 7 To one side efthe collar 7 is pivotalljy connected the link 6 tad to the othr'end of s'aidli'nk is piveten tehheetea theflever' 5Qwhich is pivetaliy i oh eden the. hinge 5. secured to the bin 1, adjacent theshaft 3. Thislever 5 is adapted to hold the chitchpiec'e gt normally in ehgegemeht with'theihijih s thus p'r'evidfiig' a, ravity eettieted C'lilfli, however, if es'tifiieieht qti'ehtit-yof foodis in the trough to presstheexdisengaging the clutch and allowing the to spider 8 to be revolved without revolving the shaft 3 and spider 2 but when there is not sufiicient quantity of food in the trough, the spiral and shaft will revolve with the spider 8. This spider 8 is covered by means of the shield 11 so that only two or three of the arms are exposed so that the stock in feeding can only press on one or two of these arms at a time. Vertically mounted on the shaft 3 on the crank 3 is a rod 3 which is adapted to agitate the food and keep it from packing and it is supported by a bracket 3.
Though I have shown and described a particular construction, combination and arrangement of parts, I do not wish to be limited to thi particular construction, combination and arrangement but desire to include in the purview of my invention, the
combination, construction and arrangementv substantially as set forth claims.
It is obvious that with this construction, there is provided a stock feeder in which the animal, by revolving the spider 8 when there is only a small quantity of food in the troughl will turn the spiral 2 causingthe food in the bin to move outwardly through the cylindrical piece l to the trough; that when sufi'icient quantity of food is in the trough to press the extended end of the lever 5 upwardly, the clutch piece 4; will be disengaged from the hub piece 8 and the turning of the spider will then not affect the feeding mechanism; that the device is simple and economical of construction, clurable, easily installed and does not readily get out of order.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. In a. stock feeder, the combination of a bin, provided with an aperture and a trough extending therefrom, a cylindrical piece secured in the bottom of said bin, providing communication between said bin and said aperture, a spiral revolubly mounted therein, a spider mounted in front of said bin over said trough and means for engaging and disengaging said spider with said spiral. 2. In a stock feeder, the combination of a bin provided with an aperture and a trough extending therefrom, a cylindrical piece secured in the bottom ofv saidbin providing communication between said bin and said aperture, a spiral revolubly mounted therein, a spider mounted in front of said bin over said trough, means for engaging and disengaging said spider with said spiral and in the appended Copies of this patent may be obtained for cured in the bottom of said bin, providing communication between said bin and said aperture, a spiral revolubly mounted therein, a spider mounted in front of said bin over said trough, means forengaging and disengaging said spider with said spiral, means for preventing said spider from turning in one direction and means for covering a portion of said spider.
l. In a stock feeder, the combination of a bin provided with an aperture and a trough extending therefrom, a spiral revolubly mounted in the bottom thereof, a feeding mechanism mounted in front of said bin over said trough adjacent the aperture in said bin, gravity actuated means'adapted to connect said; feeding mechanism with said spiral and means in connection with said connection means whereby, when there is sufficient quantity of food in the trough, said spiral and said mechanism will disconnect.
5. In a stock feeder, the combination of a bin provided with an aperture and a trough extending therefrom, a spiral revolubly mounted in the bottom thereof, a feeding mechanism mounted in front of said bin over said trough adjacent the aperture in said bin, gravity actuated means adapted to connect said feeding mechanism with said spiral, means in connection with said connecting means whereby, When there is sufficient quantity of food in the trough, said spiral and said mechanism will disconnect and means in connection with said spiral for agitating the food in said bin.

In testimony whereof, I havehereunto set my hand at Kansas City, Missouri, this 19th day of January, 1918.
