Description
UNITED STATES PATENT OFFICE.
RIGHD. M.
HOE, OF NEXV YORK, N. Y.
DOUBLE-CYLINDER PRINTING-PRESS.
Specification of Letters Patent No. 2,629, dated May 20, 1842.
To all 'Lu/wm it may concern:
Be it known that I, RICHARD M. HoE, civil engineer and machinist, of the city of New York, in the State of New York, have invented certain Improvements in Double- Cylinder Power Printing-Presses; and I do hereby declare that the following` is a full and eXact description thereof.
In its general construction this press combines what have been found to be the most valuable of the properties contained in the well known presses invented and patented in England by Applegath, by Cooper and tMiller, and by Napier, upon the particular manner y of arranging the respective improvements in these presses, which I have combined in my press. I do not now found any claim to an exclusive right; b-ut I have made certain new and useful improvements in presses of this description, the first of which improvements consists in a novel and etficient arrangement of the levers and Springs which are used to stop the momentum of the bed of the press at the end of its traversing` motion in either direct-ion; and the second is an improvement in the manner of l'aising` and lowering the pressing cylinders, so as to cause them to rise and fall with the most perfect steadiness, 'without the `possibility of their being subjected to those jerks, to which they have been liable under a. rapid motion of the press as heretofore constructed.
In the accompanying drawing Figures 1 and 2 represent two side elevations of my press; Fig. 3 an end view thereof; and Fig. a a representation in outline of such parts Vas contain my new improvements; those portions of the press which are not necessary to an explanation of these improvements being omitted in this figure. In the respective Figs. 1, 2 and 3 I shall give references to those parts only which I believe to be substantially new, the others being already known to those who are conversant with modern printing' machinery.
For preventing` the injurious efiects upon the machinery which under the ordinary arrangement of the press are produced by the stopping' of the moment-um of the bed, when its motion is to be reversed, the following` is the plan adopted by me. On the lower part or basis of the frame work of the press I inclose, within suitable tubes or cases (or arrange on the outside or around lron or other rods), three, four or any other desired number of spiral springs, which are laid'horizontally in the direction of the length of the press each spring' being contained within a separate case or tube (or on a sep'arate rod) on, or within, which it may move freely. InFig. 4, A A reprcsents one of these Springs, and B B the tube, or case, within which it is contained; the latter being shown in section for the purpose of exhibiting the Springs within it. Into each end of the tubes, or cases, containing' the Springs, there enters a follower, or piston D, D, the e-nds of which bear'against the Springs ft A; each set of these pistons is connected to a piece of metal C C` by which they are made to operate together, either as a bearing to sustain the reaction of the Springs, or as followers pressing them inward.
E `E, in each of the figures, is a lever working on a fulcrum pin F, in standards G G, there being several ho-les through the ;lever and standard to vary the fulcrum of thelever. The levers E are connected to the pieces O by a jointed rod H H. As the bed traverses back and forth, a stop on the underside of the bed, is brought into contact, alternately, with the upper ends E/ E', of the levers, and the bed is, by the recoil of the springs, efect-ively checked, without any injurious jarring of the machinery.
Fig. 5 is a top view of the case, or tubes, containing` the Springs, these being represented as four in number, with their pist-ons, the pieces C, C by which the pistons are combined together` and the connecting rods i H H. By the foregoing arrangement of the respective parts, the bed may be arrested at any required period of its progress and that with but little play in the Springs which consequently retain their elasticity unimpaired for a great length of time. Although I have named, and prepared, spiral Springs, others may be used which may be similarly combined, and operate so as to produce a like effect.
My improvement in the manner of raising and lowering the pressing cylinders consists in placing a pinion on the main driving shaft which pinion gears into a wheel having' a cam on its axis that rocks two horizontal rock shafts, which raise and. lower the pressingcylinders alternately, with a perfectly smooth and equab'le motion. To effect this I place a pinion upon the main driving shaft J which pinion gears into a toothed wheel K Figs. 1, 3 and 4:. The situ- VL being` a portion of the interior surface of the side frame L L, upon the exterior surface of which the wheel K, and the pinion L', are situated. M, Fig. 4 is a cam on the aXis of the wheel. K, which cam opera-tes within an opening` hh in the rocking' piece O, the arms of which rocking' piece are jointed at P P, tothe toggles or progressive levers Q Q Q' Q'V; the latter turn on stationary pins R R, affixed to the frame L;
'and theI lower ends of the former are firmly attached to vibrating' or rockinp,` shafts S', S', which cross from side to side of the machine, their ends S, S` bearing' on the connecting pieces T, T, which are alternately forced down by them, as one or other of the shafts is depressed by the toggles.
U, U, are pairs of rods made fast to the connecting' pieces T T, and to the brasses V, V, which constitute the bearings of the AQ'udg'eons of the pressing' cylinders; the rods U, U, slide up and down freely in suitable guides, pass through spiral Springs VV, 7, and have on them adjusting' nuts X X` by which the tension of the Springs, and the position of the rods, may be readily adjusted. The form given to the cam M, and to the cavity N, within which it revo'lyes, as shown in the drawing` is such as will alternately raise and lower the two arms of the roclring` piece O, and will consequently, through the intermedium of the parts above described` compel the pressing cylinders to ris-e and fall with an equable motion, witha out its being possible that those jerks should occur to which they are liable under the construction of the apparatus by which their motion has heretofore been effected.
Having thus fully described the nature of my improyements in the double cylinder power printing` press what I claim therein as new and desire to secure by Letters Patent is-- l. The particular arrangement of the spiral or other Springs, levers, pistons, and their appendag'es, for arresting the molnentum of the bed the Springs being' placed on, or near to, the foundation or base of the machine and being connected with the levers which receive the blow of the bed at either end, as its motion is about to be reversed; the whole arranlg'ement and operation being substantially the same with that herein described.
' 2. I claim the manner herein set forth of combining' and arranging` the apparatus for raising and lowering' the pressing' cylinders; that is to say, I claim the manner of lgoverning` and l'eg'ulating` this motion by means of a pinion placed on the main driying` shaft and Operating' upon aewheel carryingz,l a cam which actuates. a rocking' piece connected with tog'g'le joints or progressive levers that raise and'lower the respective cylinders alternately through the intermedium of an apparatus arrang'ed substantially in the mannei' herein fully made known.
