RAMMlNG-IVIACHINE.

Specification of Letters Patent.

Patented Oct. 31, 1905.

To all whom it nuty concern:

Be it known that we, JOHN WRIGHT SEAVER and ALFRED ERNST, residents of Cleveland, in

the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Ramming-Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to an improved ramming-machine more particularly adapted for compressing coal for by-product coke-ovens, the object of the invention being to provide a car or carriage carrying its own motor, which latter also automatically operates rammers at both ends of the car or carriage as well as propels the car back and forth over the coal being compressed, and provide handlevers whereby the entire operation of the apparatus is always under the complete control of the operator.

With these and other objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a top plan view. Fig. 2 is a view in side elevation. Fig. 3 is a fragmentary end view, and Figs. 1 and 5 are enlarged views in section, illustrating the plunger-bar clutch mechanism.

1 represents beams or framework on which rails 2 are located, and on which rails the wheels 3 of a car or carriage 4 are mounted to run. At each end of the carriage is a vertical frame or head 5, strengthened by bracebars 6 and having angle-iron bars 7 secured in opposite sides of its open center and forming ways for guides 8, secured to the vertically-movable plunger-bars 9. The bars 9 carry plungers 10 at their lower ends and are operated by our improved mechanism hereinafter described.

On the car or carriage 1 an electric motor 11 is located,vand its shaft 12 has a balancewheel 13 thereon. A pinion 14: on shaft 12 transmits motion to a larger gear 14 on a shaft 15, and a smaller gear 16 on the shaft meshes with a large gear 17 on a shaft 18, parallel with shaft 15 and located near the center of the carriage or car. On the ends of the shaft 18 sleeves 19 are mounted and locked to turn with the shaft by clutches 20, operated by hand-levers 21 and 4:2, respectively, which latter extend to one side of the carriage and in convenient reach of the operator. On the ends of these sleeves 19, which project outside of the carriage, crank-arms 23 are secured and are connected by rods or links 24; with crank-arms 25 on shafts 26, near the ends of the carriage, and as the crankarms 25 are considerably longer than crankarms 23 the turning of the latter simply oscillates the shafts 26. At the center of shafts 26 crank-arms 27 are secured and are connected by rods or links 28 with clutch-operating arms 29.

Sleeves 30 are mounted loosely on the plunger-bars 9 and are provided with webs 31, which carry pins 32, and on these pins the arms 29 are pivoted. The arms 29 have sleeves or hubs 33, located on the pins 32, and said hubs or sleeves are cut away or recessed, forming shoulders 34 in the path of grip pins or pieces 35, loosely mounted in openings in the sleeves 30, and when the arms 29 are elevated the shoulders 3 1 engage the grip-pieces 35 and force them into tight engagement with the plunger-bars and securely lock them to the sleeves 30, so that when the latter are elevated by the crank-shafts 26 and arms 29 the plungers are likewise elevated.

Laterally-projecting pins 36 are provided at the upper ends of webs 31, and bell-crank trip-levers 37 are fulcrumed on the pins 36, one member of each lever connected by short links 38 with the pivotal connection between the links 28 and arms 29 of its respective mechanism, and the other members of the trip-levers are slotted to move on the plungerbars and project across the upper ends of the sleeves 30.

Suitably spaced apart and in the path of tripping-levers 37 stops 39 and 40, respectively, are located, the former or lower stop serving as a gripping-stop and the latter or upper stop constituting a releasing-stop, as will now be explained.

Assuming the parts to be in the position plunger-bar 9, locking the sleeve and bar together. Acontinued upward movement of the link 28 elevates sleeve 30 and bar 9 until the trip iing-lever 37 engages the releasingstop 40, when the contacting end of the tripping-lever will be forced downward, as shown in Fig. 5, and through the medium of the short link 38 will force arm 29 downward and release pressure on the gripping-piece 35, and the plunger-bar and plunger of their own weight will fall to compress the coal. The reverse movement'of shaft 26 will force the sleeve 30 downward until the tripping-lever 37 engages gripping-stop 39, whichengagement compels upward movement of the end of the lever 37 in contact therewith. This movement of lever 37 through the medium of link 38 causes the initial upward movevment of arm 29, causing the grip-piece to bind against the plunger-bar 9, when the operation above described is repeated.

The parts shown are so arranged that the plungers at the ends of the car or carriage will be operated alternately; but it is to be understood that they may be operated simultaneouslythat is to say, while the construction shown will raise one plunger while the other falls the plungers might be respectively raised and lowered simultaneously.

On shaft 18 an eccentric 47 is loosely mounted and is locked to the shaft by a clutch 41, controlled by a hand-lever 22, and the band or strap around this eccentric 47 is connected with an arm 43, secured on a shaft 44. A shaft is mounted in the carriage parallel with shaft 44, and said shafts 44 and 45 have intermeshing gear-segments 46, which compel them to be simultaneously oscillated when arm 43is oscillated by the eccentric 47. Each of these shafts 44 and 45 has a depending arm 47, to the lower end of which dogs 48 are pivotally secured, and counterbalanced levers 49 are provided to hold the dogs in or out of operative position.

A notched rack 50 is provided on the framework, .and the dogs 48 project in opposite directions, so as to propel the carriage in both directions, according to which dog is in op eration. I/Vith the parts shown in Fig. 2 the left-handdog 48 at each movement of the shaft 44 engages in a notch of the rack and propels the carriage forward a distance of one notch, which is of the same or less space than the width of the plunger. The other dog is held out of operation byits counterbalanced lever until the carriage reaches its extreme movement in one direction, when the counterweighted levers 49 engage stops 51 and are thrown to their opposite positions, thus throwing out the dog which had been in operation and throwing in the other dog and reversing the direction of movement of the carriage.

In the upper portions of the plunger frames or heads cams 52 are secured upon cross-shafts 53 and are adapted to engage the plungerbars 9 and hold the plungers out of operation. These cams 52 are operated by levers 54, connected with levers 55 at the center of the carriage by rods 56, and weighted arms 57 are secured on the shafts 53 to normally hold the cams out of engagement with the plungerbars.

It will be seen that with our improvements all of the controlling-levers are located adjacent to each other and enable the operator at one position to control the entire operation of the apparatus.

A great many slight changes might be made in the general form and arrangement of the parts described without departing from our invention, and hence we do not restrict ourselves to the precise details set forth, but consider ourselves at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of our invention.
