As shown, a stand 3 ismounted upon the top of the base 1 and .securedt-hereto'in any desired manner. A longitudinal channel is formed along the top of the stand 3,- and a cover plate i is provided, rigidly attached to the marginal walls 5 and-botthe .stand channel and, in the form shown, comprises a bottom plate 7 to which the side'plates- 89 are rigidly attached, .a' bottom part and a top part. Intermediate the top and I bottom parts a body piece 11- is positioned correspondingin thickness with the size of type tobe cast. A plurality of such body ieces are preferably provided? each corre sizes of type the machine "is adapted-to produce. 1

The top and spondlng in thickness with a particular 817.8 of tvpe, thus accommodating the various or plate 7, ancLbottom jet block 12, and an.

upper mold blbck or plate 10. and upper jet block 13. A jet' piece 14 is provided adapted to cooperate "with the bodypiece 11 and po- Y sitioned in thecayity formed between thetop and bottom jet blocks. The cross-section of the jet piece 14 .preferably corres ioc sponds. and is proportionate, to the size of;

the'body piece 11, or in other word's,'to the size of type ,to be cast.

movable-in relationzto the side plates 8 and The upper .mold ,block and jet block' are vertically'movable in relation to each other and also vertically 9 respectively to conform to the thickness of a l the body piece' and jet piece respectively with which they are temporarily Cotipiat: mg.

Any suitable means may be rovided for controlling the movements of the body piece maintaining the mold block an .jet block in and jet piece. In the form shown, the suitable longitudinal relation to each other body piece 11and jet piece 14 are each reand also for retaining these parts in their movably attached to a common pusher plate 5 proper position in relation to the side plates 21, by means of. pins 22 or other suitable 70 8 and 9. In the form shown, the side pieces means upon the pusher plate extending into 8 and 9 are each provided with a suitable suitableopenings in the body iece and jet vertical groove or.channel 15, upon their iece. A shaft 24 is mounted in suitable A inner faces and the mold block and jet block earings 24-24 on the stand 3, and a bell 10 are each provided with a projection crank lever 23-.23 is rotatably mounted on 75 15 is also provided with a transverse groove 15 Suitable meansare provided to control 25 near its extremities to force the same down- 8Q erably near its center to draw the mold block A substantially similar arrangement may I 4 ,strated that'the cap screw may be omitted equiva ent means 10 on its lower face arpiece 11 to receive the rib 10 and cooperate thickness of the members 11 and 14.. The

adapted to cooperate with these grooves rethe shaft 24. A shaft- 25 isalso mounted in spectively to control the longitudinal posuitable bearings 26-'26" on the base 1 and a sition of the parts and permit the vertical cotiperating bell crank lever 27-;27 is romovement above described. The jet block tatabl mountedon the shaft 25. The arm I 2 27 o the bell-crank'lever' 27- 27. is progo and the mold block with a projection adaptvided with a bevel segmental gear adapte ed to eooperate'therewith to lock the same. to cooperate with a similar gear upon the together and yet permit the desired vertical arm 23 of the bell-crank lever 23-23. The movement between them. free end of the arm 27 of the bell-crank SKI--27 is provided with a suitable roller 28 35 ada ted to coiiperate with a cam 29 upon a sha t 30 rotatably mounted in suitable bear-.- ings upon the base 1.- v ,7 1

Any suitable -means may be empolyed to adjustably connect the pusher plate 21 and 9'0 the lever 23.- As sho'wn,a link 31 is pivotally attached to the plate with a part threaded to fit the threads upon the interior of a. sleeve nut 32, which in turn is threaded externally to fit an opening in a block 33,

which is pivotally connected -to the extremity of the lever 2 3 by a pin 34., The threads upon the interior and exterior of the nut 32 are pitched oppositely, that is, one is right hand and the other is left hand,- so that a rotation-of the nut will change'the distance'between the block 33 and the pusher plate the combined pitch of the threads upon the nut.

I-norder to adjust the mold cavity to produce type of varying set widths, the nut- 32 is rotated to change the distance between the plate 21 and the block 33.

The .vertically movable member 19 is adapted to be depressed after each type has been cast in the mold to permit its ejection therefrom, the top face of the member 19 forming in its depressed position a support for the type as it istransferred across the recess in the stand'3. I

Any suitable means may be employed for periodically elevating and depressing the member 19, and controlling the extent of'its movement. As shown, a stem 35 is attached to the lower end of the member 19 by a,pin 36, a-suitable opening in the base 1 being provided to guide the lower. end of the stem 35. A collar 37 is attached rigidly to the stem 35 and a bushing 38, and a spring 39,

the vertical position of the mold block 10 and jet block 13. As shown, a air of set screws 16-16 are provided ine plate 4 positioned to engage the mold block 10 ward, and a 'cap screw 18 is positioned in a suitable opening near the center of the plate 4: and arranged to engage a suitable threaded opening'in the mold block 10 prefupward and hold the same firmly in contactwith the'ends of the set screws 16-16 thus accurately controlling the vertical position of the mold block.

be provided for the jet block 13, but in the form shown, only the screws 17-'-17' are provided to force the jet-block downward, as in actual practice it has been demonwithout materially interfering with the operation of the device. 7 r v In the form shown, the'upper. mold block .10 is rovided with one or more ribsior ranged to extend across the mold space an adapted to form the characteristic nicks on one side of the type. A recess 01' groove 11 is formed in the upper face of the body therewith. v The parts above described form three walls of the type andjet cavities, the body- "wise size of which 18 determined by the remaining side of the mold is formed by a vertically movable member 19 positioned in 1 aslot 20 in the stand 3, and dapted to fit against the ends of the moldan jet blocks 50 to close the open side of the mold. The setwisevsize of the type isdetermi'ncd by the distance the body piece 11- is positioned from the vertical member 19 during the casting operation. 35 Any suitable means may emplwedfor are loosely mounted on the stemabove the Any suitable means may be employedfor adjusting the vertical movement of the mem-' ber 19 and providing a positive stop to bring the'top of the member 19 substantially to the level of the bottom of the mold cavity. As shown,ablock 44 is positioned in a diagonal groove 44 in the stand 3, and provided witha diagonal rib 45 on onqgof its faces,the rib 45 is adapted to engage a shoulder 46 on the member 19 when the member is depressed and form a limit to its downward movement.

The arts are so proportioned that the l ver 40-40 is given excessive movement so as to cause a compression of the spring 39 to take up any lost motion in the parts and insure the proper, seating of the shoulder 46 upon the rib 45 each time the vertical member is depressed. In the form shown,.the adjustment of the stop44 is accomplished by means of a screw 47 extending into the recess 44 and threaded into theblock 44.

A suitable head or handle is provided upon the screw '47 having two concentric flanges 47-47 adapted to engagethe opposite sides of a bearing 48 on the stand 3. By rotating the screw 47 a very close and accurate ad: justment of the stop block 44 may be made. Any suitable form of matrix may he employed, and held in position to cotiperate with the mold in any desired manner. As

shown, the'matrix 49 consists of a flat rectangular plate having a character. or die on its flat side. The matrix 49 is mounted upon a matrix carrier comprising a carriage 50 provided with a groove or depression 51 upon each side, or other suitable means,

adapted to cooperate with guides or wa s 52 upon the standto accurately guided. e

movement of the carriage 50, preferably'in' a horizontal direction at substantially right angles to the mold. Y

The vertical position of the matrix upon the carriage is preferably controlled by an inverted T-sha ed block or matrix support 53; one arm 0 which is adapted to extend beneath and support the matrix. The block 53 is positioned in a suitable chamber or recess in the bottom and front of the carriage and provided with suitable means cotiperating with the sidesof the carriage to permit the desired vertical adjustment of the block. A screw 54 or other suit'ablemeans connects the block and carriage, and controls the vertical'adjustment of t 1e block, thus providing convenient means for accurately adjusting the'posit-ion of the character .upon the matrix tothe mold. I

Any desired means may be employed for clamping the matrix. upon theblock. As

shown, afilling block 55 is mounted in suit able waysupon the block 53 and a bent plate '56, is attached to the top of the block 53, and adapted to hold the block 55 firmly in place. Thematri'x 49 is inserted in a groove 57 -in the block 55, and an upturned lip 58 on the block 53 engages the lower edge of the matrix, providing a suitable seat for the matrix and preventing its vertical or lateral movement on the block 53'.

Matrices of the kind shownin the draws ings are usually formed of uniform 'dimenr ever, merely for the purpose of illustration,

ranged for employing any kind of matrices as it is evident that mymachine may be-ar- I whether possessing thecharacteristics-above described or-otherwise;

- In the form shown, the vertically in'ovable member 19 is provided with a recess or depression 19 extending longitudinallyoithe member alongone comer, its front-edge .as shown in Fi s. 5 and9, the walls .of the recess being a apted' to engage-boththe front and one side of each matrix when in casti'ng position, it being understood that this side portion is of uniform width in all matrices of the character described. An

auxiliary member-59,fis'adjustably attachedtoithe pusherplate 21, and operates outside the mold cavity. This member is adapted to engage the opposite side of the matrix'at the mold and limit the movementof the pieces 11 and 14 toward the vertical member 19, and "thus control the setwise dimen-" sions of the mold cavity.

Any'desired means may be employed for adjusting the relation between the auxiliary mold member 59 and the mold piece 11. As shown, a suitably formed recess is pro ,vided between the plate 8 and the body piece 11 andthe block-59 is fitted in the recess and arranged to move longitudinally there- I In;

A lug 60 is formed upon the block 59 adapted-to extend intoan opening 61 in the pusher plate-21. The opening 61 is madeconsiderably longer than tlufldimension of the lug 60 to ermit longitudinal adjustmentbetween the lock 59 and-pusher 'late '21.

Iii-the form shown, a series ofp ates 60" -(see Fig.6) of various thicknesses, are-pros vided for insertion in the opening 61 hetweemthe end of the opening and the mg 60,

and a set screw 62 threaded into th'e'end' of the pusher late 21 is provided to clamp the parts tight y together toprevent I0ngitudi-- The plates A nal movement therebetween.

temporarily out of use may if desired be 911- venientlyplaced at the opposite side of the lug in the opening 61 and clamped in place by the set-screw 62, though of course thisrotated to cause mold member- 59 to contact with the;edge of is also preferably is not essential to the operation of the de-- vice. These plates are preferably numbered according to their thickness, and as each matrix is stamped upon its face with the width of its particular character in points, it is only necessary for the operator to place the plates corresponding to the number upon the matrix in the opening to produce the proper size of mold cavity-for the matrix. This being done, the matrix carrier 50 is advanced against the mold and the cam shaft 30 rotated to bring the mold members into casting position. -The sleeve-nut 32 is then the end of the auxiliary the matrix, and press its opposite edge firmly against the recessed wall of the vertical member 19. By this arrangement an extremely accurate adjustment of the mold cavity is secured and the type produced are of uniform sizeand accuracy.

Any preferred means may be employed to operate the matrix carrier. In the form shown, a stem 63 is rigidly attached to the carriage 50 and provided with a head 64, and a spring actuated collar 65 arranged to move longitudinally of the stem, and resiliently forced toward the head 64. A lever 69 is loosely mounted upon the shaft 25-with its upper end bored longitudinally to receive a cylindrical stem 66 having a forked head 67 adapted to engage the head 6 upon each side of the stem 63. A set screw 68 or other suitable means is provided to retain the stem 66 in its elevated position. The opposite end of the lever 69 is provided with a roller 70 arranged to cooperate with .a cam 71-, mounted upon the shaft.30, thus providing means for positively withdrawing the matrix carrier from the mold. The collar 63- engages the forked head 67 and resiliently maintains the same in contact with the head 64, the spring 65, forming a cushion which, when the machine is in operation. seats the matrix resiliently against-the mold, insuring a perfectly tight joint between the mold and matrix, and compensating for wear in theparts. The stem 66 is adapted to-b'e thrust into the opening. in the-lever 69 or lowered sufficiently to release the matrix carrier and facilitate vide convenient means as desired. 7

The metal pot may be of the usual or any preferred form or-eonstruction for storing a suitable quantity of metal and maintaining the same at a proper temperature,-and may be arranged in any desired-manner for for changing matrices periodically introducing a quantity of the metal contained in thepot into the mold. In the form shown, the metal pot comprises a reservoir or crucible 72-provided with a jacket or housing 73, a nozzle 74 projecting through the lower front side 01' the jacket. and means for controlling the. discharge of its removal, to prometal from said nozzle, the whole being preferably supported so that the nozzle opening will constantly be presented to a port eommunicatingwith the jet cavity of the mold. The nozzle 74 is connected to the reservoir 72 by apassage 75, a recess 76 and .a well or cylinder 77. A suitable valve or choker 78 1s positioned in the passage to control the opening therethrough, and the discharge of metal from the reservoir.

The cylinder 77 is preferably circular, of uniform section, and located vertically near the center of the bottom of the reservoir with ,its upper end open. The passage 75 extends from the nozzle to the cylinder an circular in section. .The recess 76 is formed in the bottom of the reservoir72 near the cylinder 7 7 and extends downward to a point slightly below the bottom of the passage 75, and communicates freely therewith. The valve or choker 78 is formed to snugly fit the passage'75 and is provided with a tip or point suitably formed to fit within and close the nozzle opening. A duct 79 extends longitudinally of the choker 78 and terminates near t etip or outer end in two'openin' 's 81-81. The choker 78 is referably so,f ormed that when in position c osing the nozzle, the tip oft-he choker will be just flush with the face of the nozzle, and the passage 75 open to the 76, so that metal in the reservoir is free to pass into the passage and the lower portion oft-he cylinder 77. \Vhen the choker is retracted to open thev nozzle, the body of the choker extends across the lower portion of the recess 76 and completely cuts off com recess munication between the passage 7 5 and the recess.

The operation of the choker 78 ispreferably controlled by a bell-crank lever 80-8O pivotally mounted at the top of the metal pot upon suitable brackets 8282 The arm 80 extends downward through the reservoir into the recess 76,. where it is suitably formed to engage an annular groove 83, or other suitable" means, upon the choker for positively controlling its position. The arm 80 extends forward, and near its free end is connected by means of a link 48 (see Fig. 11) to the arm 85 of the bell-crank 85---85 pivotally mounted upon the-shaft 25, with its arm 85 extending downward into the path of a projection or cam 86 upon the shaft 30. A spring 87, or other suitable means, extends from a support upon the arm 80 to a bracket 88 rigidly mounted -on the sup ort 82 and is adapted to normally hold t e link 84 .in an elevated position and the choker closed.

The cylinder 77 is fitted with a. plunger shaft 25. A downwardly extending central member .95 is provided upon the lever 95 with a roller 96 at its extremity adapted to sha ft- 30.

cooperate with a cam 97 mount-ed .upon the A spring 98 or other suitable means, is attached to the lever 95 tending to resiliently hold the lever and associated parts at the lower limit of their movement,

while the cam 97 is formed to engage the roller 96 and'elevate the parts to raise the plunger 89 to the upper limit of its move- 5 ment and hold it there until the parts are in position to receive a charge of metal from' the pot, when a depression in the cam per- -mit-s the plunger to drop suddenly'under the actionof the spring 98.

The metal pot' supporting arm 93 is preferably pivotally mounted at one end upon the pedestal 1. asat 99 and is formed to curve about the rear of the metal pot, with its-free end resting upon the opposite side of the base 1, and secured thereto by a suit- I v rotate the shaft 30. As shown, a motor 130 able pin 100 or other convenient means, so that when desired the connections between the levers 80 and 91 and their respectiveoperating links 84 and 94 may be released,

the pin 100 re'in0ved, and the entire metal pot swung back from the mold, .afi'ording convenient access to the back' of themoldand the front of the metal p'ot.

. The metal pot may be m'ountedupon the arm 93 in any suitable manner. As shown, two lugs or'brackets 101-101 are provided upon opposite sides of the pot, projecting through the jacket 73, and suitably formed to rest upon the arm 93 to support the pot; Each log is preferably provided with an adjusting screw 102 or equivalent means, adapted to engage the arm to adjust the I vertical position ofthe pot; The nozzle 74 communicatin vertical position of the plate 103 con-. trolled by a set screw 105 extending through the plate 4, and against sidewise movement 7 103 is providocl' with aconical seat forltheis secured in operative relation to the mold: by means of a nozzle plate 103 fitted toth'e back of the mold and hziving-arropening with the jet cz'ivity.- Y The by its position between the shoulders 104-404 of the adjacent parts. lfhe plate nozzle 74 adapted tohold the parts sot-ha the opening'in the nozzle will accurately register with the opening in the plate.

type previously tacle. As each type viously cast A link 119 connects the free end of the arm 118, to one end of a lever 120 mounted intermediate its ends upon the shaft 25. A roller 120 is provided upon the opposite end of the lever 120 adapted to cooperate with a cam 121 upon the shaft 30,

and a spring 122 extending from the lever 120 to a suitable portion of the machineis adapted to resiliently force the roller into The cam thinnest type the machine is adapted to cast without engaging the-body piece 11. The thickest type will therefore only be enga ed at their forward edges, as it is obvious tat the operation of the mold as above described is such as to always bring the front edge of all type as discharged from the mold into exactly the same position, regardless of their thickness. Immediately after the retraction of the partsll and 14 the cam 116 is moved to release the type and the e'ection of the succeeding type from the mol advances the ing stick 123.

Any desired-means may be employed to break and remove the jets from the ty andthereafter tool or finish the feet. shown, an arm or breaker 124 is rigidly attached to the link 84 positioned to engage the jet attached to the foot of each type as it comes to rest after being ejected from the mold. A pocketor opening 125 is provided in the stand 3 directly beneath the jet ends of the type when in the above described position. At each operation of the link 84 the breaker 124 engages viously cast and presses ing the same from the type and forcing it into the pocket) 125, whence it is directed by the chute 126 into any convenient recepis ejected, the type preare pressed forward, and the in the foot of each type is acted it downwar breakrough break upon by the cutting lips of a plow or cutter -127,-attached to the stand 3. A projecting lip 127 (see Fig. 8) on the plow s adapted to engage the jets if for any reason they are not entirely removed by the breaker 124, and its curved under face forces any remaining portion of the jet downward before it reaches the cutting lips of the plow. 'lhe link 84,has a positive downward movement, and ordinarily the breaker 124, will thoroughlyremove the jets, so that in ractice it has been found that the projecting ip 12? ma be'omitted without interfering with the satisfactory operation of the machine. The plow 127 is preferably so mounted u on the stand 3 that the-same may be rea ily removed and replaced b another plow havg cutting lips of suitable dimensions to low the feet of type whose jets are of arger or smaller cross-section. Suitably that the space between them may cast toward the type receivthe jet of thet pe preformed trimming knives 128-428- are also attached to the plate 114 and shoe 115 adapted to operate simultaneously with the plow 127 to trim the front edges of the type' and remove any burs or fins of metal adhering to the type. The shoe 115 is vertically adjustable in relation to the plate 114 iii-order conformto the body-wise size of the 'mold cavity. this purpose suitably formed screws- 132 are provided, tapped and adapted to pass throughthe slots 1 133in the vertical supports 134 -134to clamp the shoe firmly thereto.

For

Any desired portion ofthe mold maybe rovided with suitable cooling means for reducing the temperature of the partswhile in operation, in the usual or any suitable manner. In the shown,-the jet block 13 is provided with one or more water channels 131 for this purpose, the remainder of the mold parts being preferred constructionwholly unprovided with cooling means.

When thus constructed the temperature of the several parts of the-mold reniain fairly even, that is, the jet blocks which are subject to the great-est heat are prevented from acquiring too high a temperature and the temperature of the body pieces of the mold approach more nearly 'the' temperature of' the jet blocks, and the type cast are preferablyparallel and the temperature of the parts are more readily controlled and maintained, greatly operation and the life of the parts.

It has been demonstrated in practice that the best results are obtained by changing the size of the jet to conform to changes in the size of the type mold so that larger type have correspondingly iarger-jets. The construction shown, ermits' ready removal of the jet piece an its replacement with another of suitable dimensions whenever desired.

In the foregoing specification I have described my improvement as a type-casting machine, but it i's'obvious that with various slight modifications, my device may be adapted to cast small objects of various shapes, and wherever in the specification or claims the word type is employe I desire to be understood as referring to such objects as well as type.

It .is also obvious that various immaterial modifications may be made in my device without departing from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact form and construction shown.
