- To all whom Lt may concern:

Be it known that I, ADOLPH G. HUPFEL, a citizen of the United States, resident of New York, county of New York, and State of 5 New York, have invented a new and useful Improvement in Keg-Handling Mechanism, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to lmprovements in mechanism for handling kegs, barrels, and the like, and has as its particular object the provision of means for conveying kegs around corners. In other words, it is designed to transfer kegs from one to the other of two tracks or skid-ways that are angularly disposed with respect to each other. It is of course understood that .in breweries and other manufacturing plants where kegs, er like containers, require to be handled in large numbers, such handling is expedited by the use of elevators, generally f the end- `less chain type, for transferring them from one floor to the other, and of inclined tracks or skid-ways for conveying them from one part to another on the same floor. In both cases the kegs are handled most conveniently lying on their sides, and in the latter, when thus disposed, it is obvious that they will roll along under the force of gravity alone and without attention except at the receiving and discharging ends of the particular section of track. Heretofore, how ever, so far as I am aware, it has not been possible to thus convey them around corners; for, inasmuch as it is only the slight bulge in the sides of the keg that keeps it in place on a straight-away track, it is evident that on even a slight curve it would be very apt to jump the track. It is also evident that the use of guide boards laterally of a track with the object of keeping the kegs in lace as they roll along is im racticable or such boards would tend to t ow the kegs diagonally of the track and so retard or stop entirely their progress thereon. My device, then, consisting of the means hereinafter fully described and particularly pointed out in the claims, is presented as a solution of the difficulties just enumerated.

The annexed drawing and the following descriptionset forth in detail certain mech anism embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing Figure 1 represents in perspective a view of one form of my improved keg-handling mechanism in its complete and assembled condition; Fig. 2 is a plan view of the keg-transferring member that forms an element of such mechanism; Fig. 3 is a cross-sectional view of a detail of the base of such mechanism 5 and Fig. 4 represents in perspective a detail of the transferring member shown in place in Fig. 2.

In such Fig. 1, sections of two regular tracks, A, B, are shown, either or both of which may becontinued beyond the transferring device if the situation so demands. A not infrequently desirable arrangement would be to have the one main track, in this instance B, extend continuously along one side of, or through, a room or building, and have lateral transversely-disposed tracks, as A, as feeders to discharge their kegs onto such mainV track. In the case in hand, then, tracks A and B are disposed and inclined to serve respectively as a keg-delivery and a keg-discharge track.

The transferring device consists, in a general way, of an oscillatory member adapted to receive a keg from the first of such tracks and discharge it onto the second thereof. Structurally the device comprises as its base a track formed of a single curved rail C disposed on the arc of a circle tangent to tracks A and B, respectively, and firmly secured to the floor by means of bolts c passing through the rail base. The preferred cross-sectional form of such rail C appears from the end view given in Fig. 1. The web of the rail decreases gradually in height from the end adjacent to keg-delivery track A to the end adjacent to discharge-track B. In other words, the rail is inclined downwardly from the one point to the other. Centrally mounted on the floor with respect to the circle, on an arc of which rail C is disposed, is a post or block C that, in addition to being itself secured to the floor, is braced with respect to such rail by two radially disposed arms C2. These latter consist preferably of pipe sections properly threaded to be screwed into openings tapped out in bosses c2 and c3, respectively formed on rail C and block C.

Boss c3 on block C is formed, in addition to the two laterally disposed openings designed to receive the inner ends of pipe-sections C2, with a vertical bore c4, Fig'. 3, in which is mounted a pin c5 provided with a spherical head c6. This pin is held against rotation by means of a set-screw c7, as shown, and upon its head is mounted the socketed inner end of an arm or link-shaft D, to the outer free end of which is attached the kegtransferring member proper. The details of the construction of the ball and socket bear-A ing thus formed are shown in Fig. 3 already referred to. As reference to such figure will disclose, the aforesaid inner end of arm D consists of a casting d provided with an opening d therethrough that is adapted to receive pin c5 and that is further provided with a semi-spherical bearing in which the head c6 of such pin is seated when the latter is secured in place in boss c3. The upper portion of the opening d is of increased diameter and is adapted to receive a plug d2 that is formed on its under face with a semispherical bearing adapted to form a bearing for the top of the pin head c6. Thus it is seen that-not only is arm D free to oscillate in a horizontal plane about the pivotal axis formed by pin c5 but that a certain range of vertical movement is also permitted it. The necessity for this will appear presently.

As has been stated, the Akeg-transferring member is mounted uponI the outer end of arm or link-shaft D and consists of a rack or table D/ adapted to receive a keg from delivery-track A when adjacent thereto and when properly actuated to transfer and discharge the same upon track B Such rack D', preferably in the form of an integral casting, Fig. 2, the base Z3 of which is of inverted trough-shape and is curved laterally to conform with the curvature of rail C over which it is designed to fit. A plurality of rollers d4, Fig. 2, are mounted on transverse axes Within this trough-shaped base d3, whereby movement of the same along such rail C is much facilitated. 'On this base are supported two parallel skids d5 so disposed as to approximately register with the rails of tracks A and B, respectively, in the corresponding limiting positions of rack-member D on track C. Normally rack, D is maintained in the first of such positions, i. e. when skids dregister with the rails of kegdelivery track A, by means of a counterweight E that is connected therewith through a cable E passing over a suitable pulley e and connected with rack D in a manner presently to be set forth.

To retain the keg upon rack D pending the movement of the latter to its second position, arms d are provided, being secured upon a rock-shaft i7 that is transversely mounted in the front end of rack-member D. against rotation, and arms d6 maintained vertical, by a pawl d, Figs. 2 and 4, that is This rock-shaft is normally lockedy direction is given to the end of such cable to prevent it from leaving the groove of the pulley by a guide-pulley d on the base of member D. Pawl d8 is provided with a downwardly-projecting elongated lug, or pin, C112, that is adapted to be engaged, as the rackmember nears its second limiting position, the one adjacent to discharge-track B, by the cam edge of a plate C3 formed integral with rail C, Figs. l and 4. The eect of such engagement is to raise the pawl and thereby release ratchet-wheel C19; rock-shaft (Z7, it will be readily apparent, is then held against turning and the arms d mounted thereon sustained from falling by the pull of counterweight E upon pulley d10 alone.

The operation of the transferring mechanism, which is entirely automatic, may now be set forth, the details of its construction having been' fully described. Assuming at the commencement of such operation that the transferring member D is in its normal position with skids d5 in register with the rails of tracks A, it will follow from what has been just said, that arms d on rock-shaft (Z7 will be locked by pawl d8 in their vertical position. A keg now rolling down track A will accordingly be received by rack D and held thereon. The impetus of the keg thus deposited` on the rack, however, assisted by the slight downward inclination of the curved track rail C, is suflicient to cause such rack member as a whole to swing around its pivotal aXis, the counterweight E being properly gaged to achieve this result.` As, in the course of such swing, the skids of the rack, on which the keg is resting, are brought into alinement with the rails of the second, keg-discharge, track B, pawl d8 is tripped by the engagement of pin dlg with cam-plate C3 and rock-shaft CZ with arms d6 thus left free to turn. The weight of the keg is suliicient to bear the latter down against the slight resistance offered by the leverage which counterweight E is given on pulley d10. Such keg accordingly rolls off rack D', down the continuation of skid-way d5 formed by arms d and onto track B. lts further movement along the latter is Wholly gravitational and it hence continues therealong until stopped. Just as soon as rack member D is relieved of the weight of the keg its return oscillation under the iniiuence of counterweight E begins. An incidental effect of such ac- Adegrees here shown. Vmatter of design to adapt the device to tion on the part of the counterweight is the restoration of rock-shaft Z7 and arms d to their normal positions in which they are secured by pawl d8. Accordingly, when the rack again occupies its initial station, all is again ready for the reception of a second keg. If the feeding of the kegs to track A is properly timed, it will be evident that the cycle of operation just indicated can be made to recur With practically no loss of time and the transfer of kegs be thus made continuous. Such timing of the feeding of thekegs can be made automatic also, if desired, by suitable stop mechanism on track A connected to be controlled by the oscillations of member D. Perfect freedom in its oscillation, in spite of the inclination of rail C, is secured to member D by the construction of the ball and socket joint whereby it is pivotally attached to the base.

1t should be noted in conclusion that my keg-transferring mechanism is not only simple in construction and, as has just been explained, entirely automatic in its operation, but that it is readily adaptable to various situations about breweries and other plants where the handling of kegs assumes formidable proportions. Thus the angle through `which the transfer is made may he either greater or less than the one of ninety 1t is also simply a operative counter-clockwise instead o f in clockwise fashion as does the one chosen for the purposes of the foregoing description.

Similarly, the use ,of other means than a counterweight for normally positioning the transferringis contemplated as being included in my invention.
