To all whom, it may concern:

Be it known that I, ALFRED MAnsHALL, printer and gold-blocker, a subject of the King of Great Britain, residing at 36 Friar Lane, Leicester, in the county of Leicester, England, have invented certain new and useful Improvements in or Relating to Presses, of which the following is a specification.

This invention relates to presses such as are used in gold blocking or embossing i. 6., printing in gold, silver, and the like letters and designs such as are used on the top bands and socks of boots and shoes and upon the bindings of books, hat sweat-bands, and labels for crowns of hats and for other purposes hereinafter referred to as the work.

In machines as at present employed the chase, which carries the type or design, is furnished with a handle by which the operator inserts it by hand into the fire-box and removes it therefrom at each blocking operation. I

In a press constructed according to this invention a carrier for the chase is provided which obviates the frequent handling in the manner hereinbefore mentioned of the chase and the loss of time incident thereto, and this carrier may be of a somewhat different con.- struction, according to the type of press to which it is applied.

According to one form of press a track or carrier for the chase is provided, so that the chase may be slid along into a position-into alinement with the gold or other leaf (hereinafter referred to as gold-leaf) to be trans.

ferred to the work, or instead of being slid the chase may be connected to a carrier, so that it can be swung into position to receive The pileor sheets of gold-leaf the gold-leaf. to be applied to the face of the chase may be supported on a table having a universal adjustment in relation to the chase.

The invention will be more clearly under{ stood from the following description, in which reference is made to the accompanying drawings.

Figure 1 is a front view of a complete press constructed according to one form of this inf ventlon, and Fig. 2 is an end view of the same. Fig. 3 shows a plan. of the feed-table for carrying the gold-leaf and its supports. Fig. 4 is a section on the line a b of Fig. 2 through the fire-box, showing the manner in which it is supported; and Fig. 5 is an under side view of the head of the press from which the fire-box is supported. Fig. 6 shows the arrangement of the oil-pad. Fi 's. 7 and S are a plan and vertical section, respectively, of the platen and frisket-fingers Figs. 9 and 10 are similar views to Figs. 1 and 2 of a modified arrangen'ient; and Figs. 11 and 12 show in end view and plan, respectively, a further method of supporting and operating the chase.

Like parts are designated by similar reference-numerals in all the figures, and Figs. A to 8 are drawn to a larger scale than the other figures.

In the drawings, 5 is the chase, which carries the die 2, the face of which is supplied with gold or other leaf without the chase being removed from the press for that purpose,- and for brevitys sake both the chase and the die are hereinafter referred to as the chase.

3 is a feed-table carried by the machine and adapted to support the pile of sheets of gold or other leaf between which table 8 and the lire-box the chase is adapted to be rowiprocated, and 4 is the platen, which is adapter to be moved and pressed up against the chase,

so that the work carried thereon may receive the impressions and leaf from the heated chase.

The type or die 2 is located in and carrled by the chase 5, in which it is securely held in its correct position relatively to the platen i by means of a screw 5*, Fig. 1, in the wellknown manner. The chase 5 is supported from the fire-box 6 by having its upper surface grooved or recessed to adapt it to engage the said fire-box, and also a carrier, track, or race projecting laterally therefrom along whi ch it is rec procated, as herenafter described. The chase 5 is held in place, so as to have a sl, ding fit on the track by means of overhang'ng metal strips 5 Fig. 2, attached one at each side thereof by screws 5 The fire-box 6, by which the chase F s heated, is 2 supported from the head 7 of the ma n frame 7 of the press by spiral springs, here nafter referred to. For th' s purpose the rpper surface of the sad fire-box ,s provided w th upstanding studs 9, and in fitt ng the fire-box 11 postion these studs are passed through corresponding holes in the head 7 and provided each w. th a sp'ral spr ng 8 and a nut 10. The said firebox i s formed with chambers to recelve the perforated gas-pipes 11 or other sui table means for heat ng the same. The adjustment of the chase rclat'vely to the platen is effected by means of the sa, d spr. and nuts aforesad and also by means of wedges 12, Fig. 4. The said wedges 12 are located in taper grooves 13, formed in the under surface of the said head 7- and bear against the upper surface of the fire-box 6.

The wedges are forced in by means of screws 14 or in any other well-known manner and their action is opposite to that of the sprfngs 8. The said carrier track or race consists of a longitudinal metal plate 15, which, in the form shown most clearly in Figs. 1 and 4, is

cast integrally with the fire-box 6 and proj ects laterally horizontally therefrom. The longitudinal edges are trued .so'as to form an even surface for the chase 5 to slide on, as

15 above described. The chase may be moved along this race or track by the hand of the operator to the point where it receives the gold or other leaf from the table 3 and back to the fire-box 6, and vice versa, or mechan- 2o ism may be employed for that purpose. Ac cording to one arrangement the reciprocating movement of the chase 5 is obtained through intermediate mechanism from a foot pedal or lever (not shown) and a spring 25. For this 2 5 purpose a bell-crank lever is-employed, one arm 16 of which is connected by a rod 17, reaching down to the said foot-pedal. The other arm 18 of the bell-crank lever has formed on its free end a cam edge 18 which bears edgewise against the adjacent curved arm 19 of a second lever, the other arm 20 of which projects upward toward the chase 5 and is connected by a link 21 to a pin 22, projecting from the said chase.

lever 16 18 and the second lever 19 20 are each mounted on pivots 16 19 respectively, supported by a bracket 23, bolted to'the ma n frame of the press. The arm 18 is prevented moving laterally relatively to the edge of the curved arm 19 by means of two plates 24, bolted or otherwise secured one on each face of the said curved arm 19. The edges of the plates 24 project beyond the edge of the arm 19, so as to form a guide for the cam edge of the said arm 18 of the bell-crank lever. It will be seen that on depressing the foot-pedal so as to lower the rod 17, and hence the arm 16 of the bell-crank lever, the end of the arm 18 will, as it moves to the right, slide along the curved edge of the arm 19 and in doing so will move the said arm 19 to the right also and its opposite arm 20, connected to the chase 5, to the left, thus eflecting the outward movement of the. chase from the firebox to 5 5 the feed-table. The return motion of the lever 19 20, and therefore of the chase, to the fire-box is effected by the spring 25, attached at one end to an intermediate point in the arm 20 and at the other end to the framework of the press. The chase during its travel along the track or carrier 15 and before it comes opposite the table 3 makes a rubbing contact with an oiling-pad, which greases the surface of the same, and thereby enables it to pick up and retain the gold-leaf with more The bell-crank st mcertainty than if such surface had not been greased.

The chase as it comes opposite the oilingpad raises the latter automatically, so as to make contact therewith, after which the pad drops down of its own weight out of the path of the chase as the latter returns from the gold-leaf table 3. The upward movement of the oiling-pad is effected upon the outward motion of the chase along thetrack 15, as will be hereinafter pointed out. 7

The oiling-pad 26 is carried by an arm 27, Figs. 2 and 6, hinged at 27 to the lower extremity of a bracket 28, secured by screws or the like to the track 15. Between the pad 26 and the hinge 27 a the arm 27 is provided with an upstanding lifting-plate 29, the upper end of which is reduced to pass through a hole in the upper portion of the bracket 28 and carries a nut or equivalent 30, forming a stop. The said lifting-plate is slotted to carry a lug 31, and the pad is raised by means of a hinged cam-piece 32, Fig. 1, carried by the forward end of the chase, engaging and lifting the said lug 31 as the chase passes along. The extent of the upward movement of the pad may be adjusted by altering the position of the said lug 31 in its slot by means of the nut 33, as shown in Fig. 6. to and fro along the track 15 are limited by a stop 34 on the said carrier in the outward di rection and by the fire-box in the return direction.

The pile of sheets of gold or other leaf is supported upon the feed-table 3, which comprises an open box or framing 3, the floor of which consists of two wedge-shaped blocks 35 37, oppositely disposed. The movement of the lower block 35in one direction, by the turning of the adjusting-screw 36 or other well-known means, raises the upper block 37, upon which the gold-leaf is carried, so that notwithstanding the reduction in the height of the pile of sheets, due to their being taken one by one by the chase, the top sheet is always maintained capable of making contact with or is raised sufficiently high to meet the chase. The said feed-table is arranged to have a universal adjustmenti. (2., it is adjustable in transverse, lateral, and vertical directions to insure the gold-leaf coming into contact with the whole surface of the chase when the operator raises the table or its supporting-rod by hand for that purpose.

The transverse direction of adjustment is effected by mounting the table upon a transverse rod 38, supported at one end by a standard 11, projecting laterally from one end of the press, the said feed-table being provided at its under side with a socket 39,'whi ch is squared to engage a similar squared portion of the rod 38. The table when adjusted to its required position on this rod 1S locked, so far as transverse adjustment is concerned, by a set-screw 40. The lateral adjustment The movements of the chase ICC IIO

of the table is obtained by mounting the rod 38 on the laterallyprojecting standard 41 by a socket connection, so that t may be slid therealong. and locked in any desired positi on by means of a thumb-nut 42, which engages a thread on the reduced outer end of the said standardand bears against the sock- '41 to raise-the table up to the chase.

eted extremity of the rod 38. A spring 43, embracing a reduced portion of the standard, normally forces tne rod 38 toward the outer end of the standard and permits of the said rod 38 beinglturned about the standqaid e said standard is carried by a bracket 41", bolted to the framework 7 of the press and provided with a vertical slot, so that the bolts 41 on being loosened permit the said bracket and standard and hence the rod 38 and table 3 to be adjusted in a vertical direction.

The gold-leaf table 3 normally rests on a stop 45, carried by one end 01 an arm 46, the

other end of which screws into and is carried by one end of the frame of the press.

The platen 4, Figs. 2, 7, and 8, upon which the work to be blocked or embossed is placed, is fulcrumed at 47 to the framework, so as to move in an arc of a circle relatively to the chase. This platen may be raised up to the chase by any suitable mechanism; but a convenient'arrangement consists of toggle-levers 48 49, operated by a hand-wheel 50. The toggle-lever 49 is secured at one end to the spindle 54 of the hand-wheel, and at the other end it is hinged to the adjacent end of the other toggle-lever 48, whose opposite end is pivoted to the under side of the platen. The hand-wheel 50 is provided on its periphery with a stud 51, adapted to come in contact witha stop 52 when the toggles are in line with one another and full force thereby contained. The stop 52 is bolted to the table or bed upon which the press is supported.

. On the face of the platen is a pair of frisketfingers 55 or equivalent, Figs. 7 and 8 under which the work to be embossed or blocked is held, and these fingers are caused to press upon the work and hold it in position on the platen 4 as the latter rises to the chase, and thus prevent the work shifting as the platen becomes more inclined. One method of effecting this is by. attaching to the slotted base-strip 56, to which the said fingers are adjustably secured by thumb-screws 57, a tail or extension 58, which contacts with a projection 59, bolted to the frame 7 of the press, and forces the fingers 55 down onto the work as the platen r'ses. The said basestrip 56 is pivoted at 60 to an intermediate point in the under part 01 the platen.

The operation of the press is as follows: A pile of sheets of gold or other leaf having been placed upon the feed-table 3, one operator depresses the foot-pedal, which, through the medium of the rod 17 and levers 16 18 and 19 20, causes the chase to be moved outward away from the fire-box along the track 15, passing in contact with the oiling-pad and finally coming to rest in a position in alinement with the feed-table 3. The same operator now raises the table by hand up to the chase by means of the projecting outer end of the rod 38, soas to feed the gold or other leaf to the surface 2 of the chase. During this operation a second operator places the work to be embossed on the platen 4 beneath the frisket-fingers, and by the time this is accomplished the first operator has released the foot-pedal, whereupon the spring 25 returns the chase to the firebox. The second operator now rotates the hand-wheel 50, thus raising the platen up against the chase with more or less pressure, with the result that the work carried thereon is embossed or blocked ac cording to the design of the die 2.

In an alternative arrangement (shown in Figs. 9 and 10) the chase when moved outward into alinement with the table 3 is adapted to be swung down onto the said table instead of the latter being raised up to meet it, as above described. For this purpose the track preferably comprises two horizontal bars 66, Figs. 9 and 10, supported at one end bya bracket 67, carried at the outer end of a horizontal stay 68, proj ecting laterally from the framework 7, into which its other end is screwed or otherwise securely fixed thereto. The chase is supported on the track-bars 65 66 by means of split lugs 69, arranged, say, two on one side of the chase and one on the other side. At a point 65 on the track-bar 65 opposite the table 3 the diameter of the bar is reduced, so that when the chase is moved along the track by the means and in the manner substantially as described the single split lug 69 on that side the chase when it reaches the re duced part 65 of the bar 65 allows the said chase to swing down onto the'table 3, the other bar 66 acting as a pivot or hinge, as shown in broken lines in Fig. 10. When it is desired to move the chase altogether from the track, it must be moved farther to the left, Fig. 9, until the split lugs 69 on the other side of the said chase reach the reduced portions 66 of the bar 66, on which they ride, when the whole chase may be removed. The universal adjustment of the table is the same in this construction as hereinbefore described.

Figs. 11 and 12 illustrate a further method of supporting and operating the chase. In this arrangement the chase is rigidly connected to or formed integral with an arm or carrier 70, so that it can be swung thereby into position to receive the gold-leaf. To effect this purpose, the said carrier is pivoted at its free end on a pin 71, carried by a bracket '72, bolted to the framework 7 of the press, as shown. The arrangement is such that the chase when in the position indicated in full lines in Fig. 12 is in its correct position beneath the fire-box and above the platen 4. In order to feed the face 2 of the chase with gold or other leaf, the carrier with the chase is swung round on the pivot 71 along the curvilinear path (shown in dotted lines in Fig. 12) until the chase 5 occupies the position shown in dotted lines in the same figure, where it is in alinement with the feed-table 3. The movement of the carrier in this latter di rection is limited by a stop 73, carried by the bracket 72. The feed-table 3 is now raised by hand, so as to feed a sheet of gold or other leaf to the surface of the chase, after which the latter is swung back until it again occupies the position beneath the fire-box 6. (Shown in full lines in Fig. 12.) The movement of the chase in this direction also is limited by a stop 74, carried by the fire-box. The movements of the chase may be facilitated by means of a handle 75, fitted to the carrier, as shown. The construction and adjustment of the table are the same as that described for the press, (illustrated in Figs. 1 and 2,) as are also the arrangement and operation of the platen in relation to the chase.
