G. JAEGER CONCRETE MIXING MACHINE Filed May 31 1924 GEBHARD JAEGER Patented I Apr. 27, 1926 UNITED STATES GEBHARD JAEGER, OF COLUMBUS, OHIO. f
CONCRETE-MIXING MACHINE.
Application fil ed May 31, 1924. i Serial No. 716,992.
To all whom it may concern:
Be it known that I, GEBHARD JAEGER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certainnew and usefulImprovement in Concrete-Mix ing Machines, of which the following is a specification.
One type of concrete mixing machine now extensively on the market includes a mixing vessel or drum having a single opening for supplying and discharging the materials to be mixed, said vessel beingimounted to be rotated on a swinging yoke, support or frame by means of which the drumcan be tilted to one side of a central or, vertical position to permit charging the drum with the materials to be mixed and to the opposite for discharging the mixed material. It is desirable that the swinging support or. frame carrying the mixing Vessel shall have means for latching it in several of the positions to which it may be swung, as for example, the charging position, one or more mixing positions, the vertical position and perhaps, though rarely, the discharging position; hence the object of the present invention is an improved and simpllfied device for accomplishing this purpose. Other' objects and advantages will appear from the disclosure herein.
The invention is embodied in the example herein specifically shown and described the features of novelty being finally claimed.
7, In the accompanying drawing Figure 1 is a view in side elevation of a mixing vessel having my invention applied thereto.
Fig. 2 is a detail view partly in elevation and partly in section looking at the left hand side of Fig. 1.
Fig. 8 is a detail partly in plan view looking down on the pinion, the latching and turning crank therefor being in horizontal section.
In theviews 5 designates the mixing vessel which has its feed and discharge opening at 5. The vessel 5 is supported to rotate on a central axial hearing as usual on a yoke 6 the vessel being provided with a circumanr bien't rack gear F" by means of which it is rotated by a pinion and power (not shown) as usual in such machines. The yoke 6 has trunnions such as shown at 6 supported being rotated.
in suitable bearings at the upper end of two upright members like that shown at 7 so that the n'iixing vessel can be oscillated while In the present instance the outer end of the trunnion is shown as having afiixed thereto or formed therewith an extended head 8 to which is secured by bolts 9 a large spur gear 10; The spur gear 10 has at its outer face a central hole 11 and a concentric groove 12 near its rim]. 13 designates a pinion that has cast with it a frame or keeper lfl between the sides; of which, is pivoted at 14 a crank arm 15 having a handle 15. The frame 13 is of such form, as show nthat the crank armcan be moved or oscillated in relation to the pinion and toward and fronr the outer face of the spur gear 10' as shown in broken lines Fig. 2. The pinion 13 is journaled on astud shaft 16 on the end of a bracket 16 that is bolted I as may be desired. Various positions of the mixing drum are indicated in full' and broken line Fig. l. 1
The crank arm 15 is, according to the example shown, provided (with a pin 15 positioned thereon or forming a part there of to enter central hole 11 of the larger gear 10 when the crankarm is pressed toward said gear; and when said pin 15 is engaged with said hole the pinion and large spurgear are locked from rotary movement because the pinion, being fixed to the crank arm, cannot rotate unless the crank arm can go with it. Likewise the pin15 may be engaged with the concentric groove 12 either at the right hand or left hand side of the center hole 11 and the pinion and spur gear locked from movement for the same reason. As the turning of the pinion die.
rectly from a position where tl'ie pin 15" engages the center hole to a position where it can engage the concentric groove at either side of that hole is effected by a movement of the large spur gear through an angle of small magnitude it is obvious that the mixing vessel may be locked and held in many diflerent positions in a largaangular move ment of the spur gear and in either direction, the number of such positions depending, of course upon the ratio of the diameter of the pinion to the diameter of the spur gear.
In order to hold releasably the pin 15 in or out of engagement as the case may be the shank of the crank arm is doubly beveled or made V-shaped at one edge, said edge when the lever is oscillated working past the V-shaped sliding pin 18 mounted on the free end of spring 19 held at its other end on the side of the pinion frame 13*, said pin projecting through a hole in the side of said pinion frame. As shown in Fig. 3 the shank of the crank arm is latched by the pin 18 at its inner or spur gear locking position. hen the crank arm is pulled outward, as shownby broken lines Fig. 2, to disengage the pin 15 from the center hole, r from the concentric groove of the spur gear, the latching pin 18 is sprung laterally outward and then inward to reengage the shank a the opposite bevel to hold the crank arm out of engagement with the spur gear. The action of said parts is similar when the crank arm is pushed in to enagage the pin 15 with the'aforesaid center hole or concentric groove of the spur gear. The move ment or the crank arm outward is limited by the closed end of the pinion frame 1 In practice therefore when it is desired to swing the mixing drum from a given position in which it is latched or locked to another the crank arm is pulled away from the spur gear as shown by broken line Fig. 2 to remove the pin 15 from engagement with said gear after which. the pinion 10 can be turned with the crank arm in the direction required to swing the'drum to the position desired. It it be desired to lock the drum in the new position such position must be such that the pin 15 alines withor stands opposite the center hole or a point in the concentric groove in order that the crank arm may be shoved toward the spur gear to cause the entrance of said pin 15" into said, hole or groove.
It will be observed that an advantage of the construction shown is that the same device, that is the crank arm, which is used to rotate the pinion and spur gear serves the purpose of locking those members in lixed position. hence it is not necessary to remove thehand from that device or to use the other hand. to operate some other and distinct device to lock said parts or the spur gear.
The forms and dimensions of the parts can be varied and parts omitted without de parting from the gist of the invention as claimed,
What I claim is:
1. A swinging member substantially as described and means for oscillating the same comprising a gear connected with said member, a driving means for said gear, a crank arm connected with the driving means, means operated by the crank arm to engage said gear to lock it from rotation, and yielding means distinct from the crank arm for holding that arm in gear locking position.
A. swinging member substantially as described and means for oscillating the same comprising a spur gear operably connected with the swinging member, a pinion engaging the spur gear, a crank arm connected with said pinion in pivoted relation thereto, and means on said crank arm for engaging the spur gear to lock itand the pinion from rotation.
23. A swinging member substantially as described, a spur gear operably connected therewith, a pinion engaging the spur gear. and a crank arm connected with the pinion for turning it, said crank arm being movable into engagement with the spur gear to lock the same from movement.
l A'swinging member substantially as described, a spur gear operably connected therewith, a pinion engaging the spur gear, and a crank arm connected with the pinion for turning it, said crank arm having means thereon for engaging the spur gear to lock it from rotation.
5.

6. A swinging member substantially as described, a spur gear connected therewith. said spur gear having on its face a central socket and a concentric recess, a pinion engaging said spur gear, a crank connected with the pinion in movable relation thereto and adapted to alternately engage said central socket and said recess.
7. A swinging member substantially as described, an oscillating actuator for said member, rotary means for actuating said oscillating actuator, a crank arm for rotating said rotary means, said crank arm being in movable relation to said rotary means and adapted to engage-said oscillating actuator to lock it from movement when moved with reference to the rotary means.
