LOUIS AUGUST SENGELE, OF VICTORIA, TEXAS, ASSIGNOR 0F ONE-THIRD TO LACY T. STEELE, OF VICTGRIA, TEXAS.

POT-FEEDER FOR TYPE-CASTING MACHINES.

To all whom "it may concern:

Be it known that I, LOUIS AUGUST SEN- onnn, a citizen of the United States, and a resident of Victoria, in the COllllly of Victoria and State of Texas, have invented anew and Improved Pot-Feeder for Type Casting Machines, of which the following is a full, clear, and exact description.

My invention relates to type-setting and type-casting machines, and more particularly to such machines as are employed to cast slugs provided with impression characters, each slug representing the line, or its equivalent, to be printed.

The main purposes of my invention are as follows: 1. To produce for a casting machine, in which there is a metal pot containing the type metal to be cast up into slugs, a

device provided with means for dropping into the metal pot old and useless slugs, one at a time, as the molten metal in the metal pot is used up in making new slugs. 2. To render the pot feeder adjustable for slugs of different len ths. 3. To prevent breakage of any movable part, due to difficulty in ejecting slug. In this connection it may not be amiss to state one or two facts concerning the operation of casting machines of the general type above mentioned.

To obtain the best results it is absolutely.

requisite that the metal in the metal-pot should be kept at an even temperature, neither too hot nor too cool. It is also essential that the molten metal in the pot be maintained at a. certain height. If the temperature of the metal is too high, it will cause hollow slugs, and will also cause the slugs to adhere to the mold. Too hot metal will also soon break down the matrices. If, on the other hand, the temperature is too low, the plunger cannot force the metal into the mold properly, causing a bad and useless slug. If the metal gets low in the pot it will also cause ill results. Ordinarily, the operator feeds the metal in the pot by hand, which necessitates his loaving the keyboard, causing loss of time and inconvenience during the day. If too much metal is added to what is in the metal-pot, such fresh metal being cool will lower the temperature of the molten metal. The regularity with which the gain and loss is equalized by this contrivance, both as to quantity and time, proves its capability of maintaining, not only a regular supply of metal but a uni- Specification of Letters Patent.

formity of temperature of the molten metal. Operators sometimes forget to put metal in the pot at the required time, which produces the ill effects of low metal. By my pot-feeder all these disadvantages are overcome, enabling the operator to remain at the keyboard, thereby greatly increasing the output of the machine. My invention seeks, therefore, upon each occasion when a supply of metal is forced out of the metal pot for the purpose of casting a slug, to add to the metal inside of the metal pot a quantity of cold metal, equal to that ejected for the purpose of casting a new slug. As a convenient means for doing this I simply cause the old slugs, which have already been used, to be fed one at a time into the metal pot, substantially the same movement of mechanism used for forcing out a charge of metal sufficient to fill the slug mold, sufficing also to drop into the metal pot an old slug or an equivalent quantity of cold metal. By this arrangement I replenish the metal contained in the metal pot as fast as it is used, thereby maintaining approximately constant the quantity contained in the metal pot, and also maintaining the temperature of the metal pot and its contents as nearly as practicable uniform.

Reference is to be had to the acconipanying drawings forming a partof this specifi ation, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a. fragmentary elevation show ing my device as applied to" a so-called linotype machine, this View showing the melting pot, a galley mounted thereover and extending upwardly therefrom for the purpose of retaining the old slugs to be used in the replenishing of the'melting pot; the view further showing lever mechanism connected with the lifting arm of the elevator for the purpose of enabling the movements of this arm to actuate my improved mechanisn'i; Fig. 2 is a fragmentary view partly in eleva- 'tion and partly in section, showing the mechanism appearing in Fig. 1, but viewed as from the right of Fig. 1; Fig. 3 is a fragmentary view partly in side elevation and partly in vertical section, showing the galley containing the slugs to be melted, and shows the ejecting blade and bell crank lever for actuating said plate in order to eject. the slugs one at a time from the galley and into the metal pot; Fig. 1 is an elevation showing the galley and the ejecting mechanism for handling the slugs to be melted; Fig. 5 is a horizontal section upon the line of Fig. 3, looking in the direction of the arrow, and showing how the ejector plate is operated by aid of a bell crank lever for the purpose of ejecting the slugs; Fig. (3 is a fragmentary elevation somewhat similar to Fig. l, but showing the device operated in connection with a comparatively wide galley and wide ejector plate, for the purpose of operating upon slugs of greater length than those ap pearing in Figs. 1 to inclusive; Fig. 7 is a horizontal section upon the line 77 of Fig. 3, looking in the direction of the arrow, and showing how the potfeeder is adjusted for slugs of different lengths; Fig. 8 is a fragmentary vertical section through the galley containing the slugs to be melted; and Fig. 9 is a detail showing how certain movable parts are automatically disconnected in order to prevent breakage in case a slug becomes fastened and is not easily dislodged from the galley.

At 7 is a galley having generally the form of a tall box. The galley is provided with a door 8 connected with it by hinges 9 and provided with fastenings 10 whereby it may be temporarily secured in closed position. it 11 are shown the slugs which are to be melted up. The galley is removable and is provided at its bottom with a slug stay 12 of the form shown in Fig. 6. This slug stay is simply a plate having a curved handle 13 and extending through slots 1%, 15 so as to support the slugs 11. When the galley is otf the machine the slug stay prevents the slug from dropping out of the bottom of the galley. When the galley is placed within the machine the operator grasps the handle 13 and withdraws the slug stay.

The door 8 and the back of the galley 7 are provided with peep holes 16, 17 to enable the operator to see the slugs in the galley and thus ascertain when the galley needs replenishing. A pair of angle strips 18 are fitted with metallic ways 19 (see Figs. 3, t), and connected with these ways are clips 20 bent toward each other, as will be understood .from Fig. 5. These clips are provided with inwardly extending bearing arms 21. L-shaped brackets 22 are connected with the clips 20 by aid of bolts 23.

At 24: is shown an ejector plate which fits slidably into the ways 19 and is adapted to reciprocate.

The ejector plate 24 is provided with a projecting portion 25 carrying a pin 26. A bearing 27 of substantially U-shape fits over this pin and is carried upon the lower end of an arm 28. This arm is journaled upon a pivot rod 29 and is integral with an arm 30. The arms'28. 30 may be considered as a bell crank lever. As this lever rocks upon the pivot rod 29, the ejector plate 24 reciprocates in a horizontal plane, ejecting the slugs 11, one at a time, simply pushing them out dgewise, the lower end of the galley being adjusted far enough above the angle strips 18 for this purpose. These slugs drop through an opening 31 into the metal pot 32 and are melted up.

Brackets 33 are mounted upon the clips 20 and are provided with portions 34 extending hcrizoptally therefrom. Bolts 35 extend upwardly through these portions. Brackets 36 are mounted upon opposite sides of the galley and engage the bolts 35, the weight of the galley thus resting upon these bolts. The hei ht of the galley above the angle strips is thus controllable by aid of the bolts 35, and ditferent thicknesses of slugs thus allowed for, as desired. hen the operator wishes to change the thickness of the slugs, he turns the screw bolts As shown in Fig. 6, the device may be employed in connection with wider galleys, so as to accon'unodate slugs of greater length. In Fig. 6 the galley is shown at '7, and except as to width is exactly like the galley 7 shown in other views. The pivot rod 29 provided with set collars 29 held rigidly but detachably in position by aid of set screws 29. In order to substitute the galley 7* for the galley 7, the latter lifted out and the galley 7 put in place as shown in Fig. This is easily done by moving the angle strips 18 farther apart, as hereinafter described, setting the collars 2S) in new positions and replacing the ejector plate 24. with a wider ejector plate 2 1. The arm 30 is journaled to a rod 37. The angle strips 18 support the weight off the melting pot and brackets 18 are secured upon these angle strips by aid of fastenings 18". These brackets )artially encircle stationary arm 18 mounted upon the framework.

Tt will be noted that the pivot rod 29 is of sufficient length to extend a little distance through the bearing arms 21 so as to permit the ready adjustment of the collars 25 1 where longer slugs are to be used. It. will also be noted that the ejector plates 24L are easily removed and other plates 2t substituted for them, as will be understood from Fig. 3. The bearing 27 is easily raised oft the pin 26 by lifting the arm 30 a sutlicient distance upward. The upper end of the rod 37 is provided with a slot 38 extending obliquely downward as indicated in Fig. 9. The rod 37 is also provided at its upper end with a leaf spring 38 bent slightly out "ard from the rod J and normally closing the outer opening of the slot 38. The arm 30 carries a pin 38" which is adapted to slip into the slot 38 by pressing the upper end of the spring 38 slightly away from the upper end of the rod 237. This rod is further provided with a rounded or beveled surface 38, the

curvature of this surface mating approximately the cnrvz-itnre of the upper end of the l af spring 38.

The purpose of the arrangement shown in Fig. 9 is to enable the rod 37, upon being awn downnuirdly, to extricate itself from i re arm 30, if for any reason it should hap' pen that this arm is momentarily unable to 1 form its stroke downward. For instance, i a s ug should happen to be unusually hard o move from the galley, there might be dauof breaking some movable part, unless the part in question or some other part were free to make its complete movement. As

37 is at all times free to move downwardly, v-ihethcr it can carry with it the arm 30 or not. it will also be seen that the connecion may be readily restored between the rod -37 and the arm 30 by merely forcing the rod 3? upward and guiding the curved surface 32% of the curved upper end of the leaf spring 3c in such manner that the pin forces the spring 88 slightly away from the up'ier end of the rod 87 and enters he slot 38. The machine therefore automatically pr from breakage in case anything goes wrong with the ejecting of the slugs from the galley.

The lower end of the rod 37 is connected to a lever by aid of a pivot pin 40. The lever 39 is journaled upon a pedestal 42 and provided with a number of holes 4C1 where- 't may be adjusted relatively to this ped- The pedestal is secured by a bolt 43 the floor 24. Journaled to the lever 39 d extending upwardly therefrom is a rod and a clamp 4:45 is mounted upon the upend of this rod, being secured thereto by of a pivot pin 47.

A clamping screw 4L8 secures the clamp at? upon the arn ll), this arm being connected with a plunger used for operating the first elevator at the machine, this plunger being connected by pivot pin 51 with the arm 4C9. upon rocking shaft of tubular form, this rocking shaft being supported upon the framework 53.

Extending upwardly from the shaft 52 is an arm A. lever is, by aid of a pivot pin so, journaled upon this arm 54 and is connected with the arm 49. The upper end of the lever is provided with a roller 58 and the latter is engaged by a revolnble cam 59 j ournaled upon the main shaft 59 of the machine. The mold wheel is shown at 0, and a bearing (31, mounted upon the stationary arm 18, supports the vise mechanism.

The operation of my device is as follows: The galley T is removed from the machine and tilled, or partially filled, with slugs 11 to be melted up. The slug stay 12 prevents the slugs from dropping out while the galley miv be seen from Fig. however, the rod The arm at?) is mounted rigidly is being handled. The galley having been replaced in the machine the slug stay is removed. ris different thicknesses of slugs may be employed, the bolts are adjusted every time the device is used in connection with slugs of different thicknesses. The lever 39 may also be adjusted relatively to the pedestal l2, and the rod 37 may be adjusted relatively to the arm 30 whenever de sired. Power being applied to the main shaft 59 the cam turns, and by acting upon the roller 58 causes the lever F5 to rock. This causes the arm l-t) to rock and the plunger 50 (for the first elevator) is thus caused to reciprocate vertically The arm acting through the rod il-5, causes the lever 39 to oscillate, and this lever, acting through the rod 3?, actuates the arm 30. The latter causes the ejector plate 24. to reciprocate so as to eject the slugs 11 one at a time throu h the opening 31 in the melting pct 32. The melting pot is thus periodically relieved of small charges of molten metal, and as ea h charge of metal is ejected the contents of the me al pot are replenished by the entrance of a single. slug.
