BENJAMIN B. BLACKWELL, OF JAMAICA, NEW YORK.

IMPROVEMENT IN PRINTERS FURNITURE.

Specification forming part of Letters Patent No. 118,425, dated August 29, 1871.

To all whom it 'may concern: l

Be it known that I, BENJAmN B. BLAoKwELL, of Jamaica, Queens county, in the State of New York, have invented a new and useful Improvement in Means for Holding Stereotype and Electrotype Plates for Printing in Newspaper Columns; and I hereby declare that the following is a full, clear, and exact description of the same, referencebeing had to the accompanying drawing which forms part of this specification.

My invention consists in the combination of a iianged holdin g-plate, (one or more,) an ordinary column-rule, (one or more,) a stereotype or electrotype plate, and a block or bed upon which to transiently rest such stereotype or electrotype plate, whereby, in the printing of newspapers from unblocked stereotype or electrotype plates, a great saving in the printers furniture or paraphernalia necessary in such cases is effected.

In the accompanying drawing, Figure l is a face view of a printers form wherein stereotype plates are held to their blocks by means of my improved holding-plates. Fig. 2 is a transverse section of the same. Fig. 3 is an enlargement of a portion of Fig. 2.

A A designate the beds or blocks upon which the stereotype plates B B rest and are supported. C G are the holding-plates or rules, which I term flanged holding-plates. The upper edges a of these plates are bent over at an angle, so that when one side is placed against the block upon which the stereotype plate rests said deflected edge or flange `will enter V-shaped grooves b in the edges of said stereotype plates, as shown in Fig. 2, or will overlap downwardly-beveled edges of such plates. I prefer, however, to provide the side edges of the stereotype plates with grooves b, because this construction admits of the impression-surfaces of adj acent plates being brought close together. D l) represent colinnn-rules of the ordinary construction, one of which is placed between two .holding-plates, C C, the same as it would be between two colinnns of type or up against the right and left-hand holding-plates in a form where outsidev column-rules for the page' are desired.

I am aware of the fact that in a pending application (led by A. J. H. Duganne) for a patent there is described a column-rule which is provided with grooves in its sides, into which are slid the stereotype plates, and I will here remark that such a rule must necessarily be made quite thick in order to admit of sufficiently deep grooves being made in it on exactly opposite sides to receive the edges of adjacent stereotype plates; and further than this, where such rule is used it becomes impossible to leave more than a certain positive blank space upon the paper, between the printing and the colinnn-rule line, whereas with my invention justifying column-strips may be crowded in between the holding-plates O C and column-rule D, and hence permit adjusting for different widths of columns toany extent desired 5 and furthermore, when it is desired to use heavy or full-faced column-rules, as in the case ofthe death of a prominent person, my invention permits the ordinary rules being withdrawn and removed, or full-faced ones being quickly slid in between the holding-plates G. ThisI cannot be accomplished where the grooved column-rules are used without removing such rules as are adapted for ordinary use and substituting in their places the same style of rules specially constructedwith a full or broad face for the purpose. And besides all this, my improved holding-plates enable the publisher to still use the ordinary column-rules in his possession and previously in use in his paper, and the cost of my improved holding-plates is merely nominal as compared with the grooved column-rules.

It will, therefore, be seen that I effect the desired result-that of holding loose or unblocked stereotype plates to their blocks or beds by means of Banged holding-plates, the flanged or deflected parts of which either enter grooves in the edges ofthe stereotype plates or overlap beveled edges of saidplates-and I employ the ordinary column-rule for imprinting the column-lines on the paper. This is quite the reverse of the operation of the grooved column-rules above referred to; there the edges of the stereotype plate slide in a groove in the rule, and the rule is provided with a column-line impression-edge.

And I accomplish many advantages by my invention; for instance, a great saving in the first cost of the devices and a simplifying of such devices; the column-width-adjusting feature, the quick changing of colunmrules with one style of face to those With another style of face; greatan ordinary column-rule, a loose stereotype or er facility in adjusting the devices so that they eleetrotype plate7 and its block or bed, substan` Will remain in true position during the lockingtially as and for the purposes herein specified.

up operation. BENJAMIN B. BLAOKWELL.

What I claim as my invention, and desire to Witnesses: secure by Letters Patent, is- A. SmNEY DOANE,

The combination of a flanged holding-plate with JOHN H. MEEKER.
