IMPROVEMENT IN PRINTERS LEAD-SHAVING MACHINES.
Specification forming part of Letters Patent No. 193,315, dated July 24, 1877; application filed July 17, 1876.
To all lwhom it may concern:
Beit known that we, CLAUS G. BLOMGREN, OSCAR N. BLOMGREN, and SwnN A. HAW- KINSON, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Printers Lead-Shaving Machines; and we do hereby declare the following to be a full, clear, and
`exact description thereof, which will enable others skilled in the art to which our invention appertains to make and use thesame, reference being had to the accompanying drawon the line :vw in Fig. l; and Fig. 3 repre-v sents a vertical transverse section of the same, showing those parts which are at the left hand ofthe line y y in Fig. 1.
Like letters of reference indicate like parts.
The object of our invention is to provide a machine for shaving the leads and slugs used by printers in leading the type when setting up the form and our invention consists in so constructing and combining the operating parts of the machine as to admit of being adjusted to dress the leads or slugs to any desired uniform thickness while passing oncethrough the machine.
In the drawing, A represents the frame, which is made of wood or metal, in the form shown, or in any other form that will receive the operating parts of the machine. B is a cap or bed, which is made of metal and permanently attached to the frame in any suitable manner. C C' and D D' are the front feed-rollers, and E E' and F F are the rear feed-rollers, which extend upward through the bed B,and are respectively mounted on vertical shafts journaled in suitable boxes attached to the lower surface of the bed. G, H, I, and J aregear-wheels, mounted on the shafts of the feed-rollers C, D, E, and F, respectively, and adjusted to engage with corresponding gear-wheels on the shafts of the feed-rollers C', D', E', and F', by which means the latter feed-rollers are made to rotate uniformly with and by the' rotation of the feed-rollers C, D, E, and F. K, L, M, and N are beveled-gear wheels, which are also mounted on the shafts of the feed-rollers C, D, E, and F, respectively, and adjusted to engage with corresponding beveled-gear wheels K', L', M', and N', on a horizontal shaft, O,which is journaled in suitable boxes attached to the bed of the machine. P is the main driving-shaft, which is journaled in suitable bearings attached to the bed B, or to the frame of the machine. Q is a beveled-gear pinion, mounted on the inner end of the shaft l?, and adjusted to engage with a corresponding beveled gear wheel, Q', on shaft O, by which means a rotary motion is imparted to the said shaft O, and consequently to the feed-rollers, by the rotation of the main driving-shaftP. Mounted on the outer end of the said shaft P is a bandwheel, P', around which is passed a belt, (not shown,) communicating with any suitable motor for imparting motion to the said shaft. R is a transverse shaft, journaled within the bed B, and extending to a point near its center, as shown in Fig. 1.
Mounted upon the inner end of the shaft R .is a cutter-head, R', carrying a series of cutters, a, and adjusted to revolve with said shaft. S is a head-block, attached to the upper surface of the bed B, between the feedrollers C and F, and is adjustable, so as to admit of being moved toward or from the cutter-head, and is firmly secured in a fixed position at any desired point by means of setscrews d, arranged within the vertical uprights e on the bed, and adjusted to engage with lugs f on the outer edge of the headblock. S' is a guide-block, adj ustably attached to the upper surface of the bed, between the feed-roller C' and cutter-head, and is provided on its outer side with a pressure-spring, g, the elasticity of which is such as to hold the guideblock firmly against the lead, so as to press 1t against the head-block as the lead is moved forward by the feed-rollers.
The head-block S is provided with a cutter, h, adjustable, to cause its cutting-edge to project through the face of the block to, and 1n contact with, the back of the lead.
T is the finishing-cutter, which is adjustably attached toltheV headlblock S,.in aplaneA with the center of the cutter-head-andnis so-l arranged as to allow the lead being shaved' to pass between it and the head-block.
The object off thistclamp=plate is? toihold the lead against the head-block, so as to prevent the lead from being sprung by the friction of the revolving cutters.
m m are the edging-cutters, which are ad.
justably attached to a head-block, A', secured to the end of the bed, and are so arranged as to" admity of. being raised or! l`owered,.so. asy tov engagey the; edgeszo thelead 'as-' the' lead is moved forward' by. theffeed-rollers',I by which means the' lead iscut to any desiredwidth.
Mounted' upon they shaft: Ris: apulley, b, aroundwhich; isv passed a belt,-,(fnot shown` communicating with any suitable: motor, for imparting a-rotary movement tothe said shaft'.y In using. our` said machine, the leadsare first? cut` in strips'ory blanks ofz the desired size,l and upon motionbeingimpartedto Ithe several parts of the I machina, asv described, the.; said blanks are insertedconsecutively between-r thev feed-rollers O',andfthereby movedfonward to and between the rollers.DD',and.E against the cutter h', which cuts ai thin shaving-,from thebacle of they blank, andso as to `leave the'blank smoothand true. The; blanlrLv is then, by a further. movement of"therfeedro1lers, movediforward.l against'the face-of the headblock,and in contact with the revolving cuttersy a, by whichV the faceof the blanki is cutaway, so as' to leave the-lead` of ai uniform thickness: The lead, in its forward movement', thenpasses between the feedrollers E E', to and in contact -with the finishing-cutter T, by which the ridges formed on the face of the lead by the revolving cutters are; cut. orrshaved off-,t there- E by finishing the face of the lead; and by tlie'furt-'her'frward movement of the lead it passes between the feed-rollers F and F', and gbetween the cutterszm-jmg., by whichthe edges of the lead are shavedo smooth and true, so as to leave the lead of a uniform width its entire length. l n
