HERBERT STERLING WILSON, OI" KIRKWOOD, MISSOURI, ASSIGNOR 'lO INLAND TYPE FOUNDRY, OF ST. LOUIS, MISSOURI, A CORPORATION TYPE-PERFEOTING MECHANISM.

T 0 all whom it me concern:

Be it known hat I, Hnnnnn'r STERLING WILSON, a citizen of the United States, and a resident of the cit of Kirkwood, county of St. Louis, and Sl t-ate of Missouri, have invented certain new and useful Improvements in TypePe-rfecting Mechanism, of which the followin is a specification.

My invention re ates to type perfecting and consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings, which form part of this specification, and wherein like symbols refer to like parts wherever they occur, Figure 1 is a side view of my perfecting mechanism; Fig. 2 is a diagrammatic view showin the connection of the perfecting mechanism to the actuating mechanism; Fi 3 is an end elevation of the perfecting mechanism; Fig. 4 is a plan view, partly sectional, of the actuating devices; and, Fig. 5 is a sectional detail of the resilient plate for sustaining type in the channel. Fig. 6 is a erspectlve view of the inner side of the side plate with parts mounted thereon. Fig. 7 is a perspective View of the type carrier. Fig. 8 is a cross section of the type carrier. ig. 9 is a de tail showing a modified form of the type gripping jaw of the type carrier, in which the upper inner surface of the gripping jaw is ofis'et and rovided with a resi ient p ate or s ring fins 1 with its inner surface.

The perfectin mechanism is preferably supported by a Eracket 1 fixed to the main frame 2 of the type casting machine, which is preferably constructed as shown in my Patent No. 828,080, granted August 7 1906. The support for the type perfecting mechanism has guides thereon in which a type carrier 3 reciprocates preferably in direct alinement with the line of motion of the mold cover 4. At one end of this type carrier is a type clamping device which consists of a bar 5 fitted with guides provided therefor in the sup orting racket so as to itself be idb relativel to the carrier. The endmost portion of t e slidin bar or jaw slide 5 projects beyond'the bonfy of the carrier an is arranged so as to he flush with the top of the carrier and has a lateral oifse't 6 opposite the end of said body. In order to give some resiliency to the action of the jaw slide, it 1s provided with a thin resilient Specification of Letters Patent.

plate 6 (as shown in Fi 9.) The top of this effect portion is fius with the top of the carrier. In the space intervening be tween the end of the body of the carrier and the overhanging end of the jaw slide 5, slides a vertically reciprocating ejectorbar 7 mounted on the carrier so as to move therewith. In order to provide friction suflicient to hold the ejector bar in its adjusted position, it is provided with a sprin 8 which bears against the wall of its gui e. A second spring 8 is mounted in the carrier in position to bear downwardly on said ejector bar and normally hold its top below the top of the carrier. The s ace between the end of the carrier body an the overhanging end of the jaw slide constitutes the chamber which receives the type ejected from the clamping jaw 9 at the end of the mold cover of the ty e casting machine when the jaw and cha m er come into vertical alinement, and the verticall reciprocating ejector bar 7 constitutes the ottom of this chamber.

The type casting mechanism may be of any usua construction, wherein there is a reciprocating mold cover, indicated at 4, equipped with a clam ing device here typified by the clam ing aw 9 and the ejector 99, for ejecting t e type from said jaw into the gripping jaw on the perfecting mechanism, when the mold cover has reached the right-hand limit of its throw and the carrier its left-hand limit. This mechanism, which handles the unfinished type prior to its transfer into the ty e perfecting mechanism proper, is hereina ter designated as type feeding mechanism, since it delivers the unfinished type directl to the perfectin mechanism and in tie manner describe further on.

Above the type carrier 3 and flush therewith is a cover 10 therefor. Fixed on one side of the cover is a erfecting knife 11 consisting of a plate aving a series of sharp teeth ad'usted to lie flush with or slightly below t e top edge of the type carrier and thereby be in position to tr1m the set shoulder of the type as the type is forced past it in the carrier. A second knife 12 is mounted with its teeth immediately under the teeth of the first mentioned knife for the nrpose of perfecting the easier set shou der of the type. By this arrangement, each type is rub ed and kerned separately. This last mentioned knife is mounted upon ion a bar 13 which reciprocates in guides provided therefor in the side plate 43 of the frame of the perfecting mechanism transverse to the line of motion of the carrier. This bar is normally held in its uppermost position by means of a spring 14- provided therefor, and carries at. its lower portion a laterally projecting plate 15 whose front and rear edges are beveled so as to constitute inclined planes. This plate is arranged with its upper surface parallel to the line of motion of the carrier and at such an elevation that a roller 16 provided for the purpose on the lower end of the ejector bar 7 will run flush with the upper surface of said plate, when said ejector bar is in its upper most position, consequently, when said ejector bar is depressed, said roller will strike against the inclined plane or bevel at the end of said plate 15,. and thereby force the beveled plate downwardly. The downward movement of the beveled late 15 carries with it the knife bar 13 an the lower knife 12. The urpose of this movement is to automatica lly adjust the position of the lower knife 12 to the set of the type: for, as the ejector bar 7 of the type carrier 3 is normally held by its spring in its uppermost osition, each type forced against it when injected into the clam by the ejector 99 of the type casting machme will depress said ejector bar 7 a distance exactly equal to the set of that particular type; and as the beveled plate 15 is likewise de ressed an amount equal to the depression of the roller on said e ector bar, the knife 12 which is movable with said plate 15 is itself depressed to an amount equal to the set of that particular type.

The cover 1 of the type dresser has a channel 17 extending upwardly from the lower face thereof, said channel being of sufiicient width to admit type of different body thicknesses. One side of this channel has a metal spring 18 set therein, which spring consists of a flat plate mounted upon a suitable support and tapering downwardly to its end. The position of this spring can be adjusted by means of a screw bearing against 1t. Close to its lower end the inner side of this spring is beaded or otherwise provided with a slight protuberance 19 arranged to constitute a stricture for the bottom of the clhnnel, whereby said spring tends to clamp and prevent the droppm of the type forced into the mouth of sai channel from below. Alon the sides of the vertical portion of this c annel are arranged two knives 20 opposite each other and adjastably mounted to trim the body shoulders of the type.

Mounted to slide vertically in guides on the frame of the perfecting mechanism in alinement with the vertical channel is a bolt or bar 21 whose upper-end normally rests in such a position that the lower end of the ejector bar 7 in its lowermost position will just clear the upper end of said sliding bolt. The lower end of this sliding bolt is in )osition for the outer end of a lever 22 to )ear against it. The fulcrum of this lever is so )ported preferably on the frame work of the type casting machine and its inner end is provided with an antifriction wheel 23 arranged to bear against the periphery of an edge cam 24 provided therefor on the cam shaft 25 of the machine. The free end of this lever is provided with a vertically adjustable screw 26 which is the immediate device for transmitting motion from said lever to the vertically sliding bolt- 21. In consequence of this arrangement, the movement of the cam shaft 25 causes the rocking of the lever 22 whose motion in turn is transmitted into the vertical movement of the slidin bolt 21. The vertical movement of the sliding bolt 21 is transmitted through the adjustable screw 26 to the ejector bar 7, the various movements being so timed that the ejector bar is immediately above the sliding bolt while said sliding bolt is moving. Consequently, during the upward movement of the sliding bolt, the type, which at that time re isters with the vertical channel 1.7, is force upwardly into said channel. The protuberance 19 on the spring at the end of the channel prevents the dropping of the type when the ejector bar is returned to its normal position.

By the arrangement of the channel 17 vertically above the type carrier, the weight of the superimposed type in the channel steadies the successive type in their passage past the knives 20 and the vertically reciproeating bar 7, which serves as the bottom of the ty e chamber in the carrier and as a part 0 the automatic means for adjusting the knife 12, also serves as the ejector for removing the type from the carrier and forcing them past the knives 20.

he reciprocation of the type carrier is effected from the cam shaft 25. For this purpose the cam shaft has a cam 27 thereon against which bears the end of a drag bar 28 mounted to slide longitudinally in sup ports provided therefor in the frame of the type casting machine. An antifrietion wheel 23 on the end of said drag bar is held against said cam by means of a spring 29 provided for the purpose. On its outer end, the drag bar 28 has a laterall extendinghpin 30. On the frame of the per ecting mec anism is mounted a vertical lever 31 whose lower end is connected to the outer end of said drag bar and whose upper end is. connected by a link 32 to the carrier.

By this arrangement of ting devices the reciproeatlon of the type carrier is effected from the cam shaft. It is desirable, however, to provide means wherepower transmit-.

by the length of the stroke of the carrier may conform exactl to the distance between the clamping aw of the casting machine and the type channel; and it is also desirable to provide means whereby the limiting ositions of said type carrier shall coinci c with said clamping device of the casting machine and said type channel respectively. The length of the stroke of the type carrier is regulated by shifting the point at which the drag bar 28 is connected to the vertical lever 31. For this purpose, the lower end of the lever is slotted lengthwise and the link 32 which connects said drag bar to said lever, is provided with a transversely arranged clamping in 33 adapted to slide in said slot and be c amped at any desired position therein. In order to regulate the limiting positions of said type carrier, the link 32 which connects the drag bar to the vertical lever is made ad'ustable lengthwise, as bymeans of threa ed sections connected together b .a turnbuckle 34. The lengthening of this llnk has the elfect of moving the type carrier forward; and after the stroke of the ty e carrier has been properly adjusted, said ink is adjusted so as to get the limitin positions of said type carrier at the-desired points.

The type carrier has a lever 35 pivotally mounted on' its side. The upper end of this lever is slotted to receive.& pin' 36 which projects from the jaw slide 5. The lower end of this lever has an adjusting screw 37 extending-therethrough in position to strike against a projection-or abutment 38 provided therefor on the side of the frame of the perfecting mechanism immediately before the carrierreaches the forward limit of its stroke. When the adjusting screw on said lever strikes said projection, it causes the lever to swin on its pivot andthereby move, the jaw slide forwardly relative to said carrier. By this arrangement, the jaw slide,i:which is anormally held: against the end sof the. carrier bymeans of its spring 42,

is separated therefrema suflicient distance to :permit the type-to enter the space-"between-them.- w In order torelieve the shock due to the momentum of the 'earrier, .the supporting frame-is provided with a rod 39 which projects 'rearwardly therefrom through a yoke t0 mounted on said carrier. This rod, is screwd-hreaded' and" provided with adjust in g nuts 41 which are adjusted to the proper positions to bexstruck by'the carrier at the verw limit'otits movement. r t I Ubviously, the oonstruction hereinbefore described may be ichanged. considerably without de arting from-my invention, and I do not wish torestri ct myself to such con-- struoti-onae l. 1
