This invention'relates to new and useful improvements in vibrators and more particularly to a manually operated vibrator for concrete mixers. In using concrete mixers it is a wellknown fact that when feeding the material to be mixed into the mixing drum a great deal of material will adhere to the loading bucket and it is generallynecessary to impart a number of hammer-like blows to the bucket in order to dislodge the material so that it will discharge into the mixing drum.
One oi! the olnects of my invention is the provision of a device adapted to be used in connection with the loading bucket of a con crete mixer whereby to impart a series of vibrating or jarring movements to the loading bucket so as to prevent any of the material to be discharged therefrom from sticking or adhering to the bottom of the discharge chute of the bucket.
Another object of my invention is the provision of a device of the above character which can be readily incorporated in the structure y of well-known types of concrete mixers and can be manually operated in a very efiiclent manner.
lVith the above and other ob ects in view, the invention consists of novel features of construction, the combination and arrangement of parts herelnafter more fully set forth,
pointed out in the claims and shown in the accompanying drawings wherein:
Fig. 1 is a detailed sectional view taken on he line 11 of Fig. 2, illustrating the application of my improved vibrating member applied to a concrete mixer.
Fig. 2 is a rear elevation of the supporting frame, illustrating the relation between the vibrating member and the loading bucket.
In the accompanying drawings it will be noted that a portion of the supporting frame as used in connection with the concrete mixer is generally indicated at 1. This frame por- 192 Serial in, 360,483.
able rollers 11 mounted in the looped track ways 1-. From this itv will be apparent that when the bucket'is raised and lowered the rollers 11 will travel-within the looped trackways 4, the rollers being disposed at the inner ends of the trackways when the bucket is lowered and at the outer ends of the trackways when the bucket is raised, as illustrated in the drawing; I
r In order to impart a vibration or jarring movement tothebucket when in its raised position, I provide a pair of spaced bearings 12011 the channel bar 6 and rotatably mounted in these bearings is a shaft '13 which car ries an outwardly extending arm 14. The shaft 13 is not only rotatably but slidably mounted in the bearings 12, and is limited in its movement longitudinally by means of the collars 15 upon the inner side of the bearings 12, one of said collars carrying the arm 14.
The shaft 13 has its outer end disposed at right angles to form a hand-lever l6 which is adapted to be grasped by the operator for rotating the shaft 13 and intermittently engaging the outer end of the arm 14- with the shaft 10 when disposed in its dumping or un loading position, as shown in the drawing. It will be apparent that by intermittently engaging the arm 14 with the shaft 10 it will, by the jarring of the supporting frame, including the shaft 10 and arms 8, impart a vibration or jarring movement to the bucket 7 and cause the contents thereof to be discharged into the mixing drum of the mixer itself.
When the loading bucket is moved to its raised or discharging position its movement is limited by means of the crossbar 17 which is engaged by the parallel ends 8 of the side bars 9 and said stop cooperates with said bucket supportingframe to provide a reaction me1nher for assisting the jarring effect of said frame on said bucket. It will be apparent that when the loading bucket is lowered the shaft 10 will move the arm 14 out of its path, as shown by the dotted line in Fig. 1, but the arm 14 can be readily moved to operative position for engaging the shaft through manual actuation of the lever 16.
It Will be apparent from the foregoing that I have provided a simple and inexpensive device adapted to be used in connection with concrete mixers whereby to impart a vibration or jarring movement to the loading bucket when in its unloading or discharging position so as to prevent the contents thereof from sticking or adhering to the bottom of the discharging chute of the bucket.
I claim: 1. In a concrete mixer, the combination 0 15 a movable loading bucket, a pair'of spaced arms for supporting said bucket, a shaft at the lower ends of said arms, spaced bearing loops. rollers carried. by the shaft and movable in said loops, a fixed stop intermediate said shaft and the bucket, and oscillatory means for striking said shaft to cause the frame to react against said stop and impart a jarring movement to the bucket.
In a concrete mixed-the combination of a rockably and pivotally mounted bucket carrying frame, a bucket mounted on said frame, said frame having a transversely extending member at its lower end, a fixed stop intermediate said member and the bucket, and oscillatory means for strikingsaid member to cause said frame to react against said stop and impart a jarring movement to the bucket. In testimony whereof, I affix my signature.
JOHN P. GILSON.
