CHRISTENSEN,'OF CHICAGO, ILLINOIS, ASSIGNOR TO NATIONAL ENGINEER- ING COMPANY, OF CHICAGO, ILLINOIS, A CORFORATION OF ILLINOIS DOOR-OPERATING MECHANISM FOR MIXING MACHINES Application filed September 10, 1928. Serial No. 304,990.
This invention relates to door operating mechanism for mixing machines, and concerns itself primarily with a novel arrangement whereby the doors may be manually actuated in one direction and power operated in the opposite direction.` K v The invention comprises a` novel structure and combination of parts hereinafter described and more particularly pointed out andy defined in the appended claims. p
In the accompanying drawings which illustrate a preferred embodimentJ of this invention and in which similar reference numerals refer to similar features in the different views. I p u Figure 1 is'an elevational view of a mixing machine involving this invention illustrating merely the mixing receptacle.
Figure 2 is a View similar to Figure 1 with parts broken away to` more clearly illustrate the discharge doors on the bottomvof the receptacle.
Figure 3 is an enlarged fragmentary sectional view taken on the line III-III of Figure 1.
Figure 4 is an enlarged fragmentary sectional view taken on the line IV-IV of Figure 1 looking in the direction of the arrows.
In referring tothe drawings which illustrate an embodiment of this invention, thev reference numeral 1 indicates the mixing receptacle of the machine whichis providedV with a bottom 2. In the present instance the bottom of the mixing receptacle is provided '35' with a pair of discharge openings 3 which are adapted to be closed by discharge doors 4. Adjacent the inner margin of each door opening 3 there is a rod 5 which is journaled in suitable depending lugs or bearings upon the "l0 bottom of the receptacle as shown in Figure tached to the extended end of each rod 5.
Each arm 7 is connected by an adjustable link 8 with a disc 9 which is rotatably mounted upon a driving shaft or power shaft 10 which is journaled in the supporting legs 11 of the receptacle. It might be mentioned that the shaft 10is designed to drive the mechanism for the mixing machine, and to this end it is shown as provided with a gear 10a for operating the same. The aforementioned disc 9 p is provided with'a clutch drum 12 adapted for cooperation with a clutch member 13 splined `or slidably keyed upon the shaft 10. The
The operating rod 17 is provided with an Vadjustable nut 2O below one of the keepers 18 for limiting the upward movement of the lug 16 and thereby limiting the rotation of the disc 9 in a clockwise direction.
.In the operation of the heretoforel described mechanism,let it be assumed that the parts are inthe position shown in Figure 1 and that it is desired to open the discharge doors for discharging the contents of the mixing receptacle. In order to accomplish this,V the operator will slide the plunger 17 downwardly and rotate the disc 9 in an anticlockwise direction 'as viewed in Figure 1, independently ofthe shaft 10. This rotation of the disc `9'wi ll swing the arms 7 downwardly as shownl in dotted lines in Figure 2.
and since the arms 7 are rigidly connected with the rods 5 the latter will be rotated for swinging the discharge doors downwardly into open position as shown in dotted lines in Figure 2. f
Now if it is desired to close vthe doors, the "l" operator will shift the lever 14 to engage the clutch 13 with the drum 12 of the disc 9, thereby clutching the disc 9 to the shaft- 10. As the shaft 10 normally rotates in a clochwise ldirection it will rotate the disc 9 in the same direction and swing the doors to their closed position through the instrumentality of the links 8 and arms Z Gf course, the disc 9 can only be rotated by the shaft 10 'until'it taken from the'operatino shaft of the machine.
I am aware that many changes; may be made and numerous details of 'construction may be variedthrough wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise Vthan necessitated by the `prior art.
I claim as my invention: K
