SPECIFICATION forming part of Letters Patent No. 666,409, dated January 22, 1901.
Application filed February 10, 1899. Serial No. 705,219. (No model.)
To all whom it may concern:
Be it known that I, GEORGE D. COLEMAN, a citizen of the United States, residing at Boston, in the county of Sn [folk and State of Massachusetts, have invented certain new and useful Improvements in Comminuting-Machines; and I 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.
The present invention relates to a comminuting-machine,and particularly to a machine for producing comminuted particles of metal, such as copper and lead.
The objects of the present invention are to produce a machine of simple design and arrangement adapted to produce from pigs of lead or copper comminuted particles and to so arrange the mechanism of the said machine that the pig of metal will be progressively advanced and properly guided to the comininuting-tool.
To the above ends the present invention consists of the devices and combinations of devices which will be hereinafter described, and particularly pointed out in the claims.
The present invention is illustrated in the accompanying drawings, wherein- Figure 1 shows in broken side elevation a machine embodying the same. Fig. 2 shows in front elevation and partial section, taken on the line to a; of Fig. 1, portions of the machine.
Similar reference characters will be used throughout the following specification and drawings to designate corresponding parts of the machine.
As shown in the illustrated embodiment of the present invention, the machine comprises a suitable framework, which may consist of the vertical standards 1 and 2 and the horizontal table 3, secured to the vertical standard 1. Secured to the front of the vertical standard 1 are suitable guides 4, and arranged to reciprocate vertically in said guides 4 is a tool-carrier 5, consisting of a suitable rectangular plate, to the front of which is secured the comminuting-tool 6, which, in the illustrated embodiment of the present invention, consists of a plurality of coarse rasps, the
lower ends of which rest upon a flange of the tool-carrier 5 and the upper ends of which are secured beneath a clamping-plate 7, held to the tool-carrier 5 by suitable headed bolts 8. The tool-carrier 5 is designed to be reciprocated in the guides 4, and such reciprocations maybe secured by any suitable mechanism, that shown in the illustrated embodiment of the present invention comprising a link 9, pivotally secured by a bolt 10 between ears 11 on the upper end of the toolcarrier 5, and at its upper end said link is pivotally connected with a crank-pin 12 on a disk 13, secured to the outer end of a shaft 14, mounted to rotate in suitable bearings 15, secured to the vertical uprights land 2, and said shaft 14 is provided with pulleys 16, by means of which the shaft 14 may be driven by a belt from any suitable source of power to impart vertical reciprocations to the toolcarrier 5 and the comminutiug-tool 6, supported by said carrier.
The piece of metal, such as a pig of lead or copper, to be subjected to the comminutingtools 6 is designed to rest upon the table 3 and to be fed against the working face of the comminuting-tools 6, and to secure this supporting and advancing of the piece of metal I have in the illustrated embodiment of the present invention arranged a suitable clamp to engage the rear end of the piece of metal and progressively advance the metal toward the working face of the comminuting-tools 6.
As shown in Fig. 2 of the drawings, the table 3 comprises angular members 17, consisting of vertical plates 18 and horizontal plates 19, and the members 17 are secured by bolts 20 to the opposite sides of the upright l, and when in position, as shown in Fig. 2 of the drawings, leaving a space 21 between the adjacent edges of the horizontalplates 19. The outer ends of the members 17 of the table 3 are connected by a suitable cross-piece 22, it being understood that the members 17 and the cross-piece 22 may be formed as a single casting or of separate pieces suitably secured together. Secured to the upper surface of the horizontal plates 19 of the table 3 are guide-plates 23, which, as shown in Fig. 2 of the drawings, are held in position by suitable bolts 24, passing through slots 25,
formed in said guide-plates, whereby they may be adjusted toward and from each other, according to the width of the piece of metal which rests upon the upper surface of the horizontal plates 19 of the table 3, between which guide-plates 23 the piece of metal will be guided as it is advanced toward the commin uting-tool 6. For the purpose of advancing the piece of metal toward the comminutingtool 6 there is provided a clamp 26, which comprises a horizontal base-plate 27, which rests upon'the upper surface of the horizontal plates 19 of the table 3 and is guided between the guide-plates 23. end of the horizontal base-plate 27 of the clamp 26 there is formed a roughened clamping-jaw 28, which cooperates with a complementary roughened clampingj aw 29, pivoted at 30 to a vertical post 31, projected from the base-plate 27. In order to securely grip the reduced end of a pieceof metal and hold the same while it is being advanced toward the comminuting-tool 6, the pivoted clampingjaw 29 may be arranged to be elevated by means of a spiral spring 32, placed between said jaws and surrounding the bolt 33, which passes through the pivoted jaw 29 and is tapped into a threaded bearing (not shown) in the base-plate 27 and by means of which the pivoted jaw 29 maybe forcibly moved toward the jaw 28 toclamp the piece of metal. The clamp 26 is advanced along the table 3 by means of a weight 34, which is connected by means of a cord 35, passing over rollers 36 and 37, (see Fig. 1,) to a lug 38,depending from the under side of the clamp 26, the ar rangement being such that the weight 34constantly and progressivelyadvances the clamp 26 and the piece of metal clamped thereby toward the reciprocating comminuting-tool 6.
In order to retract the clamp 26 against the power of the weight 34, I have provided the said clamp with a suitable handle 39, which may be gripped by the operator and the clamp At the forward 26 moved backwardly toward the outer end of the table 3, and, if desirable, in order to end of the piece of metal comminuted parti-l cles.
In order to insure that the piece of metal to be comminuted will be positively guidedl in a proper direction toward the commin uting tool 6, and in order to prevent it being dis-Z placed vertically by the upward movement? of the comminuting-tool, I have provided a' clamp-guide arranged to engage the upper sur-i face of the piece of metal immediatelyin front .minuting-tool.
of the reciprocating comminuting-tool. As shown in the illustrated embodiment of the present invention, this clamp-guide consists of a cross-bar 41, provided at its central portion with a sharpened blade or point 42, adjusted to engage, and preferably so positioned that it will cut into, the upper surface of the piece of metal a slight distance to prevent any lateral displacement of the piece of metal and also prevent its vertical displacement by reason of its contact with the reciprocating com- This clam ping-bar 41 is preferably arranged to be moved up or down for the purpose of positioning the point 42 with reference to the thickness of the piece of m et-al being acted on by the machine, and in order to secure this result the crossbar 41 is supported by carriers 43, which are pivotally secured at 44 to the opposite sides of the frame supporting the guides 4 or to vertically-adj ustable plates 44 secured thereto, and at their rear ends the carriers 43 are connected by a cross-bar 45, in which is pivoted a nut 46, through which passes an adjusting-screw 47, arranged to turn in a suitable bearing 48 carried by a bracket secured to the rear of the standard 1, said adjusting-screw at its upper end being provided with a hand-wheel 49, whereby it may be turned in its bearing and by means of the nut 46 raise or lower the clamping-bar 41 and the guide-clamp 42.
From the foregoing description it will be seen that as the pig or pieceof metal advanced toward the reciprocatingcomminuting-tool 6 and held in contact with the raspi'ng face of said tool,sa id tool will,=on its down stroke, remove a portionof the end of the pig in the form of comminu-ted particles, which will fall through the opening in the table into a suitable box or receptacle 50, placed beneath the table 3 to receive thesame, andthat the pig of metal will be constantly and progressively advanced as the action of the comm i nuti ng-tool reduces the size of the pig, and this operation will be repeated untilsubstantially the entire pig of metal hasbeen reduced to comminuted particles. It is necessary that a stream of water he constantlydiseharged upon the cornminuting-tool 6 and the end of the pig of metal which is being acted on by said tool in order that the conrminu ted :par-
cles maybe Washed from the face of the comerally across the front of the machine, as shown at 52, slightly in frontof the reciprocating comminuting-tool 6, and the arm 52 of the pipe is provided with suitable apertures 53, arranged to-discharge jets of water on the face of the comminuting-tool 6.
It is thought that the operation of the machine has been sufiiciently described inconnection with the foregoing description of its form and arrangement and that a further description of its operation is unnecessary.
Having described the construction and mode of operation of my invention, I claim as new and desire to secure by Letters Patent of the United States- 1. Inacomminnting-machine,thecombination with a vertical standard, of a horizontal table secured thereto and projected at right angles therefrom thus providing a support for the metal to be comminuted, guides to direct the movement of the metal, a clamp having means for clamping it upon the metal and provided with a catch to hold it in its retracted position, a rope attached to the clamp, guide-rollers therefor and a weight for moving the clamp and metal toward the comminuting-tool, a eomminuting-tool consisting of a plurality of rasps fixedly secured to a carrier by means of a clampingplate, a flange on said carrier for supporting the lower ends of the rasps, suitable guides in the vertical standard for supporting said carrier, and means for actuating said tool, substantially as described.
