To all whom it may cof/wem.'

Be it known that l, EDWARD E. PoLLooK,

a citizen of the United States, and resident of lLos Angeles, in the county of Los Angeles and State of rCalifornia, have invented certain new and useful lmprovements in Embossing Presses, of which the following is a specification.

This invention relates to improvements in embossing presses, and more particularly to presses for forming signs, advertising cards, and the like by punching characters from paper and forcing the same into a sheet of cardboard or other backing of contrasting color.

The invention has for its principal objects to provide a simple and efficient type-holding means for the press; to provide means for holding lines of type in variably spaced relation; to provide independently adjustable and removable holders for lines of type; to provide type holding means shiftable to afford unobstructed access to the paper-supporting surface; and to provide means for 25, bodily shifting the set-up type between the pressure heads of the press.

To the foregoing and other ends, which will hereinafter appear, the invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and particularly pointed out in the appended claims.

In the accompanying drawings,

Figure 1 is a vertical sectional view on the line 1-1 of Fig. 2;y

Fig. 12 a section on the line 12-12 of Fig. 8; q

Fig. 13 a section on the line 13--13 ef Fig. 8; and

Fig. 14 a transverse sectional view showsal ing a slightly modified form of `type and paper supporting means, the section being taken on the same line as Fig. 6.

The main frame 20 of the press is of boirlike form, and a stationary platen or presshead 21 is held above the frame on four vertical posts 22, the platen being clamped between sleeves 23 on said posts and nuts 2e threaded on the upper ends of the posts, A. vertically reciprocable ressure head 25 is guided in the upper en of frame 20 and is movable toward and from the platen 21 by a rotatable cam bar 26 extending through the frame. Flanged'bnshings or collars 27 and 28 keyed on opposite ends of cam bar 26 work in vertically elongated bearing apertures 29 formed in the side walls of the frame 20, the bushing 28 being formed with a tubular extension or lever socket 30 in .t

which one end of a handle or press-operating lever 37 is inserted. Thrust plates 31 and 32 engage opposite sides of the cam bar. A cage 33 containing antifriction rollers 34E is inter osed between plate 31 and the bottom wal of the frame 20, while a similar cage 35 containing antifriction rollers 36 is interposed between late 32 and pressure head 25. The wider at sides of bar 28 nor= mally engage plates 31 and 32, and it will be obvious that when lever 37 is rocked toward the left, as viewed in Fig. 1, the cam bar will force head 25 upwardly toward the platen 21. The. parts above described are constructed and arranged substantially as shown and describedin my prior Patent No.

1,168,740, granted January 18, 1916, the present improvements consisting in the provision of the type and paper supporting means hereinafter described. l

V Countersunk in the'top face of the press head 25 is a rigid bar 38, held to the head by flanges 42 along its longitudinal edges only. l

Plate 40 is preferably as wide transversely as head and forms a trough-like table movable up and down with press head 25 and open at both ends.

A sliding and swinging type-carrying frame is provided, said frame comprisingv side bars 43 and 44, a yfront crossbar 45 formed with a handle 46, and a rear crossbar or pivot rod 47. Said frame may be slidably and pivotally supported on the table 40 in various ways to adapt the same to be slid between the press heads or to be slid out from between said heads and then swung upward away from the table. In the construction shown, the ends of rod 47 are journalled in vertically elongated bearing apertures 48 adjacent the rear ends of the side bars 49 of a U-shaped slidable support or frame removably and slidably mounted 'on and guided in the trough-like table, said slides or bars 49 being rigidly connected at their rear ends by a cross-bar 50. Slides 49 rest on the bottom of table 40 and engage the side flanges-42 of the table, said slides being higher than the anges 42. y.

The cross-bar 50 and the rod 47 are above the bottom of the slides 49 and above the table to leave the rear end of the 'table free and unobstructed. This permits the work sheet to be moved rearwardly over the table and beyond the rear open end thereof so that signr sheets longer than theftype carrying frame may be used.

The side bars 43' and 44 of the swinging frame are provided with inwardly facing grooves or channels 51 and- 52, respectively, the lower sides of which are serrated, as shown, and bar 44 is providedy with atop section or p1ate'44a hinged at 53 to swing upwardly to uncover channel V5,2. Plate 44l 1s adapted to be locked at its forward end vto the main section ofbar 44 by a .spring clip or latch 54.

frame.

tudinal edgesv of the metallic type-holding bars 58. Each type-holder 58v has its lon- 75 gitudinal edges rolled laterally and thenin. wardly to form thechannels 57 and is rovided with flat end portions 59 adapted) tof engage in grooves '51 and 52 in bars 43 and 44, the under faces of said end portions being serrated. Sets of'type-holders'58 of various widths are provided jforv holding lines of type of different sizes, as shown in Figs. 1 and 2, and .an desired number of type-holders within t e capacity of the B5 frame may be inserted in the .swinging The operation is as follows:

The type 55 forming each line of reading matter are slid endwise into a type-holder 58 and are' held in the desired positionin the holder by sliding blocks 60 adapted to be locked vin place by set screws 6l. It will be understood, of course, that a pluralityV of groups of'type may be held in a singlej type holder by inserting additional blocks 60 in the holder. The type `holders are i n= serted in the swinging frame inthe desired spaced relation by passing one end 59 intov groove 51 in-bar 43' and lowering the other 100 'end 59 into groove 52 in bar 44, and are then locked in place by swinging down the top section 44a of bar 44 and locking` sa-ld section in place by means of latch 54. The

serrated edges of the end portions 59 of lth 105 holders are thus locked in engagement wi the serratededges of the grooves 51 and 52 and relative movement of the holders thereby prevented. The swinging frame 1s swung upward and rearward, as shown in dotted lines in Fig. 1, andthe sheet of cardboard 62 is placed upon the forward portion of table 40. A; sheet of colored paper 63 is then laid upon the sheet 'of cardboard.

If a multi-colored sign or the like is to be ll-rx made. pieces of different colored paper will` be laid over tHe proper portions of 'the cardboard sheet in position to be engaged by'the different groupsof type. The typecarrying frame is then swungdown until L0 the type rest on the paper. If the'paper or cardboard is not properly adjusted with relation to the type the fact will be obvious when the frame is lowered and proper atl-5 A justment may be made by again lifting the frame andshifting the paper or cardboard,

or both. When4 proper registration is obtained the cardboard, paper, sliding frame 49-50, and the swinging frame are all slid rearward in unison under the platen 21, and 100 the type-holders 58.

menare handle 37 is pulled forward to elevate head 25 and press the cutting faces of the type through the colored paper and into the cardboard sheet, thus cutting out characters from the colored paper and forcing them into the cardboard sheet. In making large signs a plurality of successive pressing operations are necessary, the frames and paper being slid rearward step by step to successively position groups of type holders under head 21. When the pressing operation, or operations, is completed the frame lil-*50, the swinging type-carrying frame,

and the cardboard and colored paper sheetsv are pulled forward from beneath head 21, the tyl'ie-carrying frame is swung upwardly, and the surplus colored paper is stripped from the cardboard sheet.

llhe platen 21 is formedwith a raised surface 2la at its under side adapted to pass between the bars forming the swinging frame and press against the upper faces of The loose pivots 48 permit relative downward movement between the hinged end of the type-carrying frame and slides 49 when pressure is applied to the type-holders. Slides 49 are adapted to engage the laten 21 to limit the upward movement of lead 25 and table- 4() and thereby prevent the type from being accidentally forced entirely through thel cardboard sheet. Any other suitable means may be provided for this latter purpose, for example` fixed or adjustable stopsmay be provided on head 21 adapted to engage the table 40er a part of head 25. By providing removable .holders for lines or 'groups of type, frequently used matter may be left set-up inholders and stored for use when desired, thus avoiding the labor of re-setting type for such matter at frequent intervals.

ln Fig. 14 a slightly modified construction is shown in which a fiat metal bottom plate 64 is nailed or otherwise fastened to the under sides of slides 49, said plate eX- tending from end to end of the slides and forming a sliding support for the cardboard and colored paper sheets. In this construction said sheets are clamped between the plate 64 and the type in the type-carrying frame during the sliding thereof rearward under the platen 21. y

1t will be obvious that signs, notices, or the like of any desired length may be formed with an apparatus "constructed as above described by advancing a long sheet through the press lstep by step and changing the type in the frame as successive port-ions of the sign are embossed. f
