MECHANISM FOR LETTERING BOOK-COVERS.

SPECIFICATION forming part of Letters Patent No.354,253, dated December 14, 1886.

Application filed April 13, 1886. Serial No. 198,781. (No model.) i

To all whom it 17mg concern.-

Be it known that I, CHARLES H. SHRADER, a citizen of the United States, residing at Govington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Mechanisms for Lettering the Covers of Books; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improved mechanism for lettering the covers of books; and it has for its object to provide means whereby a bookbinders hand-pallet can be conveniently and expeditiously removably attached to a powermachine, in order that sufficient power may be applied to the pallet to give the required impression of the type in the article to be lettered.

The invention consists in the novel features of construction and arrangement of parts hereinafter described, and clearly pointed out in the claim.

In using a pallet by hand the back and side of the book-cover to belettered must be curved. If the side of the cover is to be lettered, it is bent over a rounded block, and then one end of the pallet is set upon it and the implement rocked around it without changing its position. The reason for this operation is that a man cannot apply sufficient power to give an impression on the whole line at once, and this expedient is resorted to for the purpose of applying the pressure to a small surface at a time. As the operative has a segment of a circle to work upon, he is apt to get the line of lettering crooked, and, furthermore, as he has frequently to go over the lettering several times, great care and considerable time are required to bring the succeeding impressions directly in the first impression. It is impossible to properly letter cloth-covered books by hand, because of the hardness of the material and the deep impression required. I

A common embossing-machine, whose head is adapted to receive several lines of type and to be heated by gas or steam, answers very well for ashop havingagreat number of books to letter alike 5 but such machine cannot be advantageously used in a shop running on jobwork, where frequent changes of the type are required, because, aside from other objections, the whole head has to be heated, even though but a single line of type is used, and then it must becooled every time the type are changed.

By my invention I avoid all of the above shows a common form of hand-pallet,and also so much of the plunger orhead of the machine as is necessary to illustrate the socket in which the pallet is fitted, both parts enlarged. Fig. 3 is a side elevation of another style of press with a pallet attached.

Referring to Figs. 1 and 2, A represents an ordinary embossing-press, which can be used either with or without a pallet, its head a being provided on its under side with ways (not shown) for the reception of a chase containing type, and a pipe, a, for conveying gas or steam to the inside of the head for heating it. In the front side of head a is formed a recess or socket, b, of a shape adapted to receive the upper per tion of a pallet, and from this socket projects a pin, 0, firmly secured in the head to pass through the pallet and hold it in place in the socket. Further description of the press is unnecessary, as its construction and operation are well known to book-binders.

Brepresentsahand-pallet, consistinginerely of a frame for holding a single line of type, d, which are firmly secured therein by SetscreWb' at each end. Through the pallet, preferably just below its handle it, I form a hole, i, of a size to fit snugly over pin 0 in head or plunger a, for the purpose above stated.

0, Fig. 3, represents another common form of press, with a pallet attached in the manner aboveindicated.v In this press the pallet has a very limited vertical movement; but the bed It may be adjusted by the hand-wheeled screw 1, resting on pedestal in, so as to adapt the press for books or larger articles, as valises, trunks, &c.

\Vhcn ajob oflettering is to be done,I set the type in the pallet,heat the palletin any convenient way, preferably on a gasstove, and then IOO bring the type in contact with gold-leaf, to take up astrip just the size of theline of type. I then quickly attach the pallet to the head or plunger, draw down the lever, and thus by the great power applied force the type into the cloth or other material operated on. Instead, however, of taking the gold-leaf up on the type, I may spread a sheet of it upon the surface to be lettered, and proceed in the same manner as when lettering with an embossing-press. Furthermore, instead of heating the pallet in the manner above stated when used with an embossing-press, it may be heated by heating the head of the press in the usual manner, in which case two or more pallets may be used alter nately to advantage.

It is to be understood that I do not limit my invention to the use of any particular press other than such as is provided with a bed, a movable head or plunger, and mechanism, screw, or other similar means for operating ger, of a book-binders hand-pa1let having a V hole formed through it, the front face of said head or plunger being recessed, substantially as shown, and provided within said recess with a pin adapted to enter the hole in thepallet, in the manner and for the purpose above set forth.

In testimony whereof I affix'my signature in presence of two witnesses.
