STAMP-MILL.
Application filed. December 1, 1911.
To all whom it may concern:
Be it known that we, CHARLES M. MUL- LEN and RAY E. HALL, both citizens of the United States, residing in the city of Portland, county of Multnomah, and State of Oregon, have invented certain new and useful Improvements in Stamp-Mills, of which the following is a specification.
Our invention relates to stamp mills, although it can be applied to certain other machines where a mechanical lift and a gravity drop is used in connection with a vertically reciprocating element which performs its real function under the operation of gravity.
In most machines of this character with which we are familiar, such as a stamp mill, pile driver, certain pumps, and the like, the operating element is lifted by power operated cams, levers or the like and then released for a gravity drop. This method requires a great deal of machinery and is necessarily accompanied with more or less friction, wear and tear.
We have conceived the idea of using an electro-magnet or solenoid with which to accomplish these successive lifts, thereby greatly simplifying the mechanism neces sary to perform this function, and reducing the wear and tear to a minimum.
In order that others may fully understand our invention, we have illustrated it embodied in a stamp mill on the accompanying sheet of drawings, in which,-
Figure 1 is a side elevation of a stamp mill embodying the invention;
Fig. 2 is a diagrammatic view illustrating the electric mechanisms and connections for lifting the stamp; and
Fig. 3 is an end view of a commutator for making and breaking the electric circuit through the various solenoids.
Referring now to the drawings, we have shown a plurality of gravity stamps mounted upon carrying stems 1, 2, 3, 4, and 5, movably supported in a suitable frame made up of upright pieces, as 6 and 7 and cross beams 8 and 9, as indicated. The stamp stems 1, 2, 3, 4L and 5 are made in sections in the present showing, the upper portions 1*, 2 3 44 and 5 respectively, being of soft iron or other suitable material, and are connected with the lower portions thereof by nonmagnetic sleeves 1, 2, 3, 4 and 5. The upper ends of said stems consti- Specification of Letters Patent.

tute cores working in coils 1 2 3 1 and 5 The coils are connected, respectively, through conductors 1 2 3, P and 5 with five segments, 1 2 3*, et and 5 of a commutator shown in Figs. 2- and 3, through brushes 1 2, 33, a and 5 and contact rings l 2 3 et and 5 mounted upon the shaft of the commutator, which contact rings are in turn connected, respectively, with the segments of the commutator. The opposite terminals of said coils are connected, respectively, with a conductor 10 through connections 11, 12, 13, 1% and 15, and through said conductor 10 to a generator 19. Returning from the generator, a conductor 10 connects with brush 10 of the commutator. Thus there is provided, as illustrated in Fig. 2, a circuit extending from the generator 19 and adapted to include, in the present showing, any one of the different coils or solenoids, the commutator and back to the generator. This circuit is completed successively through the respective coils as the brush 10 of the commutator contacts with the respective segments of said commutator, as the latter is revolved. The commutator shaft is mechanically revolved through a pulley 20, and to this end is provided with bearings 2121. The revolving of the commutator, therefore, successively completes and breaks the several circuits through the several solenoids, attracts the respective cores or stamp stems and lifts them in the manner indicated by stamp 5, Fig. 1. The revolving movement of the commutator successively makes and breaks a circuit through the suc cessive coils, thereby successively magnetizing and demagnetizing the coils and consequently lifting and dropping the stamps as the commutator is revolved.
An important feature of the invention is means for automatically turning the stamp heads slightly with each stroke and thereby equalizing the wear on both the stamp and the die. This means, in the present embodiment of the invention, comprises a coiled spring 16 mounted, one upon each stem, above the head 17 and adapted to engage the cross beam 9 and be compressed as the stem is being lifted, and when compressed between the head and the beam, and the current is cut off, operates to accelerate the gravity drop of the stamp. The compression of these springs and their the spring.
recoil between the stamp head and the beam 9, not only operates to accelerate the drop of the stamp, but operates also to slightly turn the stamp head with each stroke thereof. This is due to the fact that as the coiled spring is compressed with one end thereof against the stationary beam 9 and its other end against the stamp head which is rotatably mounted, said stamp is turned or rotated slightly under the compression of This equalizes the wear between the stamp and the die, which dies are designated 18.
The several dies are mounted in any suitable mortar, here designated in section, as 22, and supported upon beams or timbers 23 set endwise, as indicated. Any suitable foundation can be made and any style of mortar can be used, as can any style of stamp head or die. 7
We are aware that the invention can be embodied in other machines than a stamp mill, and that changes and modifications can be made therein without departing from the spirit thereof, and we do not, therefore limit the invention to the showing here made, but intend that it shall cover all constructions upon which the claim hereto reads when broadly construed.
We claim:
A stamp mill of the character shown and described, comprising in combination, a supporting frame, a serles of solenoids mounted upon said frame, core members mounted to be reciprocated through said solenoids, a series of stamp members mounted to be reciprocated in said frame and having stems connected with said core members and separated therefrom by non-magnetic material, a source of electric energy with circuit c0nnections, to each of said solenoids, a revoluble commutator having a series of segments corresponding in number to said solenoids, said commutator segments being connected through said circuits, respectively, to said solenoids, and a brush member connected 1n said clrcuit and adapted to successively engage sald commutator segments as the latter are revolved, whereby to independently complete circuits through said several solenoids, substantially as and for the purpose described.
