FREDERICK O. DAVIS, OF AUSTIN, TEXAS.
SIDE GUIDE FOR PRINTING AND LITHOGRAPHIC PRESSES.
JQECIFICATION forming part of Letters Patent No. 475,677, dated May 24, 1892. Application filed November 28, 1891. Serial No. 413,413. (No model.)
To all whom it may concern.-
Be it known that I, FREDERICK O. DAVIS, a citizen of the United States, residing at Austin, in the county of Travis and State of Texas, have invented certain new and useful Improvements in Side Guides for Printing and LithographicPresses; 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.
My invention relates to side feedguides for printing or lithographic presses; and it consists in a novel construction of such feedguides, as will be hereinafter described and specifically claimed, whereby simplicity of construction, facility of adjustment, and greater effectiveness are secured and a double guide on a single support is provided, and which may be adjusted a short distance or entirely across the feed board or base of a printing or other press and can be used either on the right or left hand side of the press.
In the accompanying drawings, Figure 1 is a perspective View showing the feed-board of a printing-press which is provided with my improved adjustable side guide, the guide being shown as permanently adjusted in place. Fig. 2 is a broken top view of the front end of the feed-board, my improved side guide, and a portion of the press. Fig. 3 is a vertical transverse section of the side guide. Fig. 4 is an end view of the guide and a sectional view of its track-plates. Fig. 5 is a section of the track-plates and side elevation of one of the conducting and guarding plates of the side guide proper as entered into the track of the guide; and Fig. 6 is a section of one of the directing,guiding, and guarding plates in the line :0 0c of Fig. 3, showing the square hole in same for fitting on one of the square ends of the adjustingscrew.
A in the drawings designates the feedboard or base-feed portion of a printing or lithographic press.
B is a metal grooved track extended entirely across the press and graduated by scalemarks for the purpose of making large or small or very nice adjustments to suit the diiferent sizes of sheets guided and fed to the press.
0 is a side guide fitted to travel laterally in the track B, the extentof travel being either entirely across the feed-board or feed-base or a partof the way across, as occasion may require.
The guide-track is formed by means of two metal plates at b of a length equal to the width of the feed board A. The plate Cb has an angular groove 0, having a slight curvature at 0', formed in its top surface from end to end, and theplate b is secured to the depressed portion of the plate a by screws d, so as to overhang a portion of said groove 0 and stand flush with the top surface of the plate a. The heads of the screws cl, which fasten the plate I) to the plate a, are depressed, so as to be level with the plates at and b or a little below the same, and thus offer no obstruction. The track thus formed is fastened in a groove of the feed board or base by means of screws in such a manner that itself, as well as its fastening-screws, lies flush with the board and offers no obstruction to the guide or paper being fed into the press.
The guide is of metal and in form of an oblong block, rounded on top, vertical on its sides, and horizontal at its bottom. The bottom portion is formed with an angular tongue f, which exactly fits the track-groove 0, its shape being such that when it is enteredinto the groove and confined by plate Z) a firm connection is maintained between the guide and the track-plates, and at the same time the guide is steadied in the most perfect manner during its use or manipulations.
About midway of the guide-block a recess g is cut, and into this recess a ratchet-wheel h is fitted, and through this ratchet-wheel and the guide block an adjusting screwthreaded rod m is passed. The thread of the rod matches a screw-thread in the eye of the ratchet-wheel, while it passes snugly through unthreaded round holes in the block on each side of the ratchet-wheel. The teeth of the ratchet-wheel and the threads of the screw are constructed to work correspondingly with each other, so that any adjustment of the ratchet wheel will equal any adjustment given to the guiding, guarding, and directing plates 71., applied on the squared ends of the screw-rod. As shown, the ends of the screwrod extend a considerable distance beyond the ends of the guide-blocks, and on the extended ends the guiding, guarding, and directing plates n are secured by means of square formations p on the ends of the screwrod and in the plates themselves and confining-screws 19, passed into sockets in the ends of the screw-rod. This means of fastening the guiding, guarding, and directing plates 97. prevents their turning, and these plates in turn prevent the screw from turning when the ratchet-wheel is turned for the purpose of moving the screw longitudinally and adjusting the plates farther from or nearer to the guide-block, accordingly as the sizes of sheets being fed require. The plates n for a portion of their length are vertical with the feed-board, and at the center of their width they are formed with an approximately-V- shaped tonguej, having a slight ourvaturej, corresponding to the curvature c of the track-groove at the point where it bears, as shown. The curvatures c and j avoid an angular corner for the sheets to strike against, and thus hanging or detention of the sheets at the groove is avoided. The remainder of the plate is curved, as at 19 and extends around and abuts against the surface of the vertical portion at a point near its lower edge, thus forming a guard for preventing the sheet gliding upward and still leaving room enough for the passage of the sheets of paper, whose edges bear against the guiding, guarding, and directing plates n while theyare passing into the press. The V -shaped tongue guards against the sheets entering beneath the guide, While, as stated, the overhanging curved portion prevents upward gliding of the sheet and insures the direction of the sheet against the guiding part of the plate at, and said curved portion also tends to keep the sheet in its place.
By having a plate n on each end of the screw-rod m the guide 0 can be used on either the right or left hand side of the press. If desired, the guide may have only one plate 1 2, and a guide-block be used on each edge of the feed-board of the press; but of course it is far better to construct the guide-block with two plates 41, as shown.
In order to fasten the guide proper to the feed-board or base, a cam-lever D is provided on the block, and by turning up this lever the guide can be quickly moved laterally any distance desired by hand, and then nicer adj ustment made by turning the ratchet-wheel hon the screw-rod, and this done by turning down the cam-lever against the feed-board or the track-plate thereof the guide will be locked in its adjusted position.
For holding the ratchet-wheel h from turning a spring-pawl E is provided, and by turning this pawl away from the ratchet-Wheel said wheel can be turned to effect the nicer adjustments, and this done, by allowing the pawl to fall into gear with the ratchet-teeth the ratchet-wheel will be held from turning.
My improved side guide, with its trackplates, does not render the press unsightly,
but rather adds to its ornamentation, as all of the parts may be constructed of polished or brightened metal, and at the same time it protects the feed-board.
WVhat I claim as my invention is- 1. The combination, with a feed board or base of a printing-press, of a grooved guiding-track formed of plates extending entirely across the board, a single block having an angular guiding and retaining tongue, means for holding the block afterit is adjusted, and right and left hand adjustable side guideplates, which, with the block, are capable of being moved entirely across the feed-board, and when such adjustment is made the guide is at once ready for use, substantially as described.
2. In combination with a feeding board or base having a grooved track extended entirely across the board, a single block having right and left hand adjustable side guideplates, said block having an angular guiding and retaining tongue and said plates having, respectively, an approximately- V shaped guiding and guarding tongue, a screw-rod, means for operating said screw-rod, means for holding the rod after it has been operated, and means for holding the guide at any posi tion on the feed-board, substantially as described.
3. The side guide consisting of a block having an angular guiding and retaining tongue, right and left hand guarding and guiding plates, an adjusting screw-rod to which the plates are attached and which is held by said plates from turning, and means for operating said screw-rod for adjusting the plates 02, means for holding the screw from moving after the adjustment is made, and means for holding the guide in any desired position, substantially as described.
4. The combination of the feed-board and its track-plates and the side guide consisting of the block having an angular guiding and retaining tongue, a guarding and guiding plate n, the screw-rod, the ratchetwheel, the pawl, and the locking-lever, substantially as described.
5. The combination of the feed-board, a guide-track having its plate a curved, as at c, and a block having an angular guiding and retaining tongue, and a side guide-plate having a guiding-tongue curved, as at j, substantially as described.
6. The side guide comprising a block, a screw-rod, a guiding-plate, a ratchet-wheel, a pawl, and a locking-lever, all operating in combination with one another and with the feeding-board or feeding-base of a press, substantially as described.
In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
