PRINTING-PRESS.

Specification of Letters Patent.

Patented Sept; 3, 1907.

Application nea March 25, 1907. serai No. 364,247.

To all 'whom 'it 'may concern:

Bc it known that we, ARTHUR GEORGE HALFPENNY, a citizen of the United States, and a resident of West Hoboken, in the county of Hudson and State of New Jersey, and ALBERT ALLIs HOPKINS, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the countyl and State of New York, have invented a new and Improved Printing- Press, of which the following is a full, clear, and exact description. i i

The obj ect of the invention is to provide a new and improved printing press, more especially designed for use in business houses and other establishments, to permit accurate printing of small circulars, bill heads, 'letwithout requiring the ter heads, envelops and the like aid of an expert printer.

The invention con sists of novel features and'parts and combinations of the same, which willbe more fully described hereinafter and then pointed out in the claims. A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar `characters of reference indicate corresponding parts in all the views.

Figure l` is a plan view of the improvemeritf Fig. 2

is a Atransverse section of the same on the line 2 2 of `Fig. 3; Fig. 3 is a sectional side elevation of the same;

l Fig. 4 is a sectional plan view of the same on the line 4-'4 of Fig. 3, and Fig. 5 is a like .View of the same on the line 5 5 ofQFig. 3.' i

On a suitably constructed frame A is journaled a transversely extending shaft B provided at one outer end with a crank arm C or other means for imparting a i continuous rotary motion to the shaft B inthe direction of the arrow a. On Athe shaft B is secured asegmental support D for carrying Von its peripheral face an electro-plate or plates E from which the impressions are made on sheets Ofpaper, envelops or like articles to be printed. The electro-plate or plates E are removably secured in position on the support D by the use of bolts F extending through apertures D formed in the segmental support D, Aeach bolt F being provided at its outer end with ahead F having a beveled face or faces for engaging correspondingly beveled ends of the plate E, as plainly indicated in Fig. 3, sovthat the top-of the head does not project lto or above the type face of the plate E. The nut F2 of each bolt F screws on the inner end vof the bolt against the inner face of the support D,

and as the latter is made of segmental shape it is evident that convenient access is had at all times to the Aby a spider D2 arranged nearthe sides of the suppbrt D.

pression roller G, made of felt or other suitable material, and. having its shaft G journaled .in bearings'H ariyanged on the frame A. The bearings H rest on adjacent screws H screwing in the frame and engaging the bottoms of the bearings H, the tops of thelatter being pressed on by springs H2, so as to hold .the bearings in-position on the adjacent screws H. Now by adjusting' the screws H the top peripheral face of the impression roller G can be brought in proper relation to the :top or printing face of the plate or plates E 'held on the support D. i

On the shaft G is secured a gear wheel G2 in mesh with a gear wheel G3 secured on the shaft B, so that .when the latter is rotated a rotary motion is given to the impression roller G, so that the latter rotates with the same peripheral speed as the type or printing face of the vplate or plates E.

The gear wheels G2, G3 are preferably soiproportioned that the impression roller G makes two revolutions for each revolution of the shaft B, and hence the type mounted to slide up and down in vertical guideways A or printing face of the plate or plates E always contactswith the same'portion of the peripheral face of the impression roller AG, and consequently a 'proper printing of a large number of sheets or the-like is obtained, as the same yportion or the impression face of the impression roller G is in register with the printing face of the plate or plates E for each impression.

l' Now in case the impression face of the impression L.

roller G has become worn, the impression roller G can be changed on its shaft'G, so as'to bring the other half portion of theimpression roller G in registerfwith the printing face of the plate or plates E. I Thus the impression roller G can be u sedvfor a long time without requiring recovering or refelting of the same. I

AThe sheets or other articles to be printed are fed by hand over a feed table I supported on the main frame A and provided with transverse slots 1 engaged by clamping bolts I2 attached to longitudinally extending gages I3,-spaced apart a distance corresponding to the width of the sheets or other articles to'be printed, and fed over the table I betweenl the gages I3. By the arrangement described the sheets or other articles to be printed are always guided between the printing face of the plate or plates E and the top of the impression roller Gat the same place, with a view to properly locate/ the impression on each sheet or other article printedi Across the top of the impression roller G and immediately in front of the feed table I extends a transverse stop or gage .I against which abuts the front end of the sheet or other article fed by the operator over the table I, so that the beginning of the impression on the sheet roo is always the desired distance from the front edge of the sheet, as will be readily understood by reference to Fig. 3.

The gage J is provided at its sides with downwardly extending arms J fulcrumed loosely on the shaft G so that the gage J can swing rearwardly with the advancing sheet or` other article printed at the time. The side arms J of the gage J are connectedV with springs J 'l attached to the main frame A, so as to return the gage .l to its normal position across the top of the impression roller G after the impression has been made on the sheet or other article at the time. The return movement of the gage .l is limited by a stop pin J3 fastened to the main frame A and engaging one of the side arms J (see Figs. 3 and 4).

In order to ink Athe type or the printing face of the plate or plates E, an inlring roller K is employed, in peripheral contact with a distributing roller L, which in turn is in peripheral contact with the fountain roller N receiving the ink from a fountain O of any approved construction. TheA inking roller K has its shaft K journaled in bearings K2, mounted to slide longitudinally in guideways A'l arranged on the main frame A, and the outer sides of the bearings K2 are pressed on by springs P, the tension of which can be regulated by adjusting screws 1 as plainly shown in Fig. 3. Each of the bearings K'2 is provided with a friction roller K3 vin peripheral contact witha cam K4 supportedfrom the main shaft B `androtating with 'the saine, the ends of each cam K? terminating at the ends of the support D,

. so that when the shaitB is'rotated the inking roller K is'held in-a rearmost positionV and in contactwith the distributing roller L during lthe time the cams K4 engage the friction rollers K3, and when the friction rollers K3 reach the vendsV of the cams K4, then the springs P force the inking roller K inward towards the shaft B and the friction rollers K3 in contact with the peripheral face of the support D, thus moving the inking roller K out of contact with the distributing roller L and in contact with the type or printing face of the plate or plates E, so aste ink thesaid printing face." When the other end of the support D has been reached the friction -rollers K'a travel up the other ends of the cams K", whereby the inking roller -K'l`is caused to move bodily outwardly against the tension of thesprings P and back into .contact with the distributing roller L to receive a new supply of ink from the distributing roller L.

The shaft L of the distributing roller L is mounted to .turn and slide transversely in suitable bearings arranged on the main frame A, and one end of the shaft Lf is pressed on by a spring L', to hold the opposite end of the shaft in'contact with a cam N/ secured on the shaft N2 of .the fountain Aroller N. The shaft N2 of the.

fountain roller N is provided with a gear wheel N3 attached to the shaft B, so-thatwhen the latter is rotated a-rotary motion is given to the fountain roller N, lfor the latter to take up ink from the fountain O and to deliver this ink to the distributing roller L, which received a transverse motion in one direction by the cam N, and a retum transverse movement by the action of the spring L'.

The operation is as follows: When the several parts are in the position illustrated in the drawings, a rotary motion is given to the shaft B and a sheet or other article to beI printed is fed over the table I until its forward end abuts against the gage J, then the type or' printing face of the plate or plates E iiu'ally comes in Contact with the sheet directly on top of the impression roller G, so that the sheet is carried along and un iinpression is made on the same by the type face oi' the plate or plates E. Asr the sheet is printed it passes rearwardly and down at the rear of the impression roller G, to be discharged from the machine. In the meantime, the plate or plates E come in contact with the inking roller K, to be engaged by the same, and the gage J returns to its normal position by the action of the spring J 2, so that another sheet can be fed over the table l against the said gage or stop J to be printed by the plate E on the next 'revolution of the shaft B.

From the foregoing it. will be seen that the printing press is very simple and durable in construction, composed of comparatively few parts, and not liable to easily get out of order. It will also be seen that the plate or plates can be readily fastened in position on the bed or support D, or removed therefrom whenever desired, and the impression roller G can be readily adjusted, to bring the same in proper relation to the printing face of the plate or plates E, to insure a proper impression.

The printing press constructed as shown and described is very serviceable for a large number of business houses and other establishments, to permit the 'same to print from electro-plates small circulars, hand bills, envelops, bill heads, letter heads and the like withoutrequiring the aid of an expertprinter.

Having thus described our invention, we claim as new and desire to secure by Letters Patent:
