Specification of Letters Patent.

Patented Mar. 7, 1916.

Application filed October 13, 1915. Serial No. 56,637.

To all whom it may concern Be it known that I, CLEVELAND A. MEIS- WINKEL, a citizen of the United States, residing in the city and county of San F rancisco and State of California, have invented a new and useful Improvement in Printing- Presses, of which the following is a specification.

My invention relates to improvements in printing presses wherein an inverted horizontally reciprocating chase operates in conjunction with a vertically reciprocating platen and consists of the particular construction hereinafter set forth, and the objects of'my invention are: First, to provide an improved printing press adapted to print small matter such as menus, bills and the like, and which shall be extremely simple, cheap and effective in operation as well as construction. Second, to provide a simple and efiective means whereby an inverted chase will be moved onto a horizontal platen. Third, to provide a printing press having a horizontal and readily accessible platen. Fourth, to provide a printing press wherein no precise adjustment of the platen relatively to the chase is required. Fifth, to provide a printing press wherein the platen will be automatically adjusted to the type in the chase during an impression.

Sixth, to provide simple and efiective means for inking the type within the chase. Seventh, to provide a simple and effective means whereby the face of the inking roller may be adjusted to the face of the type. Eighth, to provide improved means whereby the ink on the inking roller may be distributed automatically. Ninth, to provide improved means whereby the ink may be applied and distributed onto the inking roller previous to the operation of the press. I accomplish these several features by means of the device disclosed in the drawings forming a part of the present specification wherein like characters of reference are used to designate similar parts throughout the said specification and drawings vand in which Figure l is a broken plan view of the improved press. Fig. 2 is a broken side olevation of the press with the parts disclosed in a normal or starting position. Fig. '8 is a broken longitudinal sectional view disclosing the position of the chase and operating parts therefor just previous to an impression. Fig. 4 is a view similar to Fig.

3 but with the inking mechanism removed and the platen raised to receive an impressum from the type within the chase. Fig. 5 1s a transverse sectional view of the press disclosing the inking mechanism with the distributer removed, and the manner in which the chase and carriage therefor are slidably mounted within the frame. Fig. 6 is an enlarged detailed transverse sectional view of the inking mechanism disclosing the attachment whereby the ink is applied to said mechanism.

The present state of the art discloses varlous types of printing presses having horizontally reciprocating chases operating in conjunction with suitable platens. The

present invention is designed to provide a simple, cheap and readily accessible press having few parts, which may be operated by one not necessarily skilled.

Referring to the drawings, the numeral 1 is used to designate a suitable frame preferably rectangular in shape and having longitudinal upper members 2 provided with longitudinal grooves 3 in the inner face thereof. The lower longitudinal members t are rigidly secured to the upper members 2 by means of the vertical members 6 and the guides 7. Between the guides 7 is slidably mounted a vertically reciprocating platen'8 having a felt or other suitable pad 9 surmounted by a suitable rubber blanket 11 over which a paper covering 10 may be secured in any suitable manner. The lower portion of the platen 8 has supporting lugs 12 formed integral therewith, resting on a transverse bar 14 which has the ends thereof secured to the ends of levers 16 pivotally mounted as at 17 to the lower members 4:, the other ends of said levers 16 being connected by means of a bar 18 the ends of which extend beyond the frame 1.

An inverted U-shaped operating handle 21 is pivotally mounted at 22 to two of the vertical members 6 and is provided with a suitable grip 23. Connecting rods 24 each having one end connected-to the operating handle 21 as at 26 are provided at the opposite ends with slots 27 which slidably engage pins 28 securedto a carriage 29 slidand to the said connecting rods 24, the pur-' pose of which will hereinafter be more fully set forth. chase 31 is also slidably mounted within the grooves 3 and'is'adapted' to receive'and' re tain type 32 therein. The chase 31 is pro-.. vided on one side of the under surface there'- of with a rack 33 wiich is alined with a similar rack 34 secured to the underside of the carriage 29. The chase 31 is detachably secured to the carriage 29 by means of a suitable hook 30 which engages a recess 35'- in the top surface of the said chase 31 as disclosed in Figs. 1, 3 and 4 of the drawings.

The racks 33 and 34 are arranged to err gage a gear 36 rotatably mounted upon rod 37 secured between two of the vertical members 6 of the frame 1. Bars 38 are pivotally mounted upon the rod 37 and are provided with lugs 39 which loosely engage 1 the lower ends of screws 41 screwedinto lugs 42 on the outer sides of the fram'e mem bers 2 and immediately above the lugs 39 so that the ends of the bars 38 may be raised or lowered, the purpose of which will herei inafter be more fully described.

Rotatably mounted'between the bars 38 is shaft 43 having a pin 44 arranged to engage a slot in a metallic distributing roller '47 ,slidably mounted thereon so that the said roller 47 will rotate with said shaft= 43. The shaft 43 is also provided with a gear 48 which meshes with the gear 36 on the rod 37. A. rubber inking roller 49 is rotatably mounted between the bars 38 and is provided with a gear 51 which meshes with the gear '48. The gear 48 is wider than either of the gears 36 and 51 so that the gear 51 may be placed out of alinement with the gear 36 and still be in mesh with the gear 48. The object of this arrangement is that when the bars 38 are raised by the screws 41 for the purpose of providing proper contact of the rubber inking roller 49 with the face of the type 32, the gear 51will not come into contact with. the rack 33 which is alined and in mesh with the gear 36.

A horizontally disposed inclined arm 53' is pivot-ally secured as at 54 and has an offset" end 56 which engages one end of the metallic distributing roller 47 slidably mounted upon the shaft 43. A depending arm 57 is secured to the under side of the carriage 29 and is provided with a roller 58 arranged to engage and move the-inclined'arm 53 as the said carriage travels toward the platen 8' which in turn will cause the roller 47 to move against and compress a spring 59 interposed between the opposite end of the roller 47 and the bar 38 on that'end. When the carriage 29 is returned to a normal'position the roller 58 will release the inclined arm 53 and the tension of the spring 59 will return the inking roller 47 to a normal position as indicated in Fig. l of the drawings.

In order to provide a simple and effective means for inking the distributing roller '47,

A. hollow inverted rectangular 'pipe 66. "or other sultabledetergent 1S poured over I have loosely mounted a member 61 having a concaved surface 62 adapted to engage and match with" said-rolle'r-47, onto the rod 37. The member 61 is some what shorter than the roller47 and is adapted to slide on the rod 37 so as to engage the full length of said "roller'47. 'The ink is applied to the concaved surface 62 and the member 61 is partially rotated on the rod 37 until said concaved surface 62 engages the periphery of the roller 47. The roller 47 is rotated by means of asuitable handle 63 detachably secured to the end of the shaft 43 as indicated in dotted lines in Fig. 1 of the drawings, and the member 61' moved longitudinally on the rotating roller 47 until the same is properly and sufliciently inked. I have also provided --a pan- 64 which is suspended under the rollers 47 and 49 and is provided with a drain In cleaning the rollers, gasolene said rollerswhile being rotated by the tem porary handle or crank 63. The detergent carries all inkfrom the rollers into the pan '64 from whence said ink and detergent is drainedinto a suitable receptacle not shown, by means of said drain pipe 66.

Theoperation is as follows: The inking rollers having been properly inked and the proper type placed within th ch ass, a sheet of paper is properly placed upon the surface of the paper-l0 on the platen 8 and is alined-withsuitable stops or pins, not shown, in the usual manner. The several partsof the printing press will be in the positions shown in Figs. 1 and 2 of the drawings.- By pulling the operating handle 21 forward, the springs 25 operating= on the pins 28, will move the carriage 29 and'the chase 31 forward and cause the 'alinedmacks 33 and 34 to engage andfigure'it will-be observed that the chase 31 is directly over the platen 8 and a sheet of paperthereon, and also that the operating handle rests upon the extremities of the bar '18. A further downward movement of the handle 21 will depress said bar 18 and there by raise the platen 8 upward and into contact'with the face of the type 32 in the in- "verted chase 31 and cause an impression of 1 said typeto be made, the slots 27 meanwhile traveling on the 13111828 against the tension of the springs 25, said tension being utilized to retain the chase 31' and type 32 therein in proper position by retaining the carriage 29 against thestops 67. The platen 8 is raised until the proper impression is obtained and it should'be noted that the proper alinement or contact of the said platen 8 with the face of the type 32 is automatically obtained for the reason that said laten 8 is capable of a slight lateral movement within the guides 7 thereby insuring an even pressure of every portion of the matter upon said platen against the face of the type 32. This impression may be easily regulated by the pressure upon the handle 21. By raising the operating handle 21 the bar 18 will first be released and the platen 8 thereby lowered, the tension of the springs 25 meanwhile retaining the chase 31 in position until the inner ends of the slots 27 engage the pins 28 and return the carriage 29 and chase 31 to normal position. Upon the return movement .of the chase 31 and carriage 29 the racks 33 and at will again rotate the inking mechanism and the face of the type 32 will be re-inked by the inking roller L9. This arrangement insures a proper and thorough inking of the face of the type. The platen 8 is supported in its lower osition by means of the levers 16 which engage one lower edge of said platen 8 as well as the lugs 12 thereon.

Referring to Figs. 1 and 2 it will be noted that the platen is readily and easily accessible to the operator. In order to change the type 32 the chase 31 is detached from the carriage 29 when it may be easily removed from the grooves 3.

It is obvious from the foregoing that I have provided an improved printing press which is simple, cheap and effective in construction as well as in operation.

It is also evident that I have provided improved means for automatically alining' the platen with the faceof the type as well as improved means for regulating the contact of the inking mechanism with the face of the type and means whereby the ink distributing roller is operated automatically.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is- 1. A printing press comprising a hori zontally disposed vertically reciprocating platen; a horizontally reciprocating inverted chase having suitable type therein and normally positioned away from the platen; an

inking roller arranged to engage the face of the type; a distributing roller operatively connected to and incontact with the inking roller; means operatively connecting the distributing roller with the chase; means adapted to move the chase over the platen and to move the platen into contact with the type within the chase; and means adapted to move the distributing roller longitudinally when the chase is reciprocated.

2. A printing press comprising a hori-.

zontally disposed vertically reciprocating platen; a horizontally reciprocating inverted chase having suitable type therein and normally positionedaway from the platen; an inking roller arranged to engage the face of the type; a distributing roller operatively connected to and in contact with the inking roller; means operatively connecting the distributing roller with the chase; means adapted to move the chaseover the platen and to move the platen intocontact with the type within the chase; means adapted to move the distributing roller longitudinally when the chase is reciprocated; and means adapted to adjust the inking roller relatively to the face of the type.

3. A printing ress comprising a suitable 7 frame; a horizontally disposed vertically reciprocating platen slidably mounted within the frame; a horizontally reciprocating chase slidably mounted within the frame and having suitable type therein and normally positioned away from the platen; an

' inking roller arranged to engage the face of the type; adistributing roller operatively connected to the inking roller and'in -contact therewith; means operatively connecting the distributing roller with the chase; means adapted to move thechase over the platen and to move the platen upward and into contact with the face of the type within the chase; means adapted to adjust the inking roller relatively to the face of the type; and means adapted to move the distributing roller longitudinally when the chase is reciprocated.

In witness whereof I hereunto set my signature.
