IMPROVEMENT IN PRINTERS GALLEYS.

Specification forming part of Letters Patent No. 121,041, dated November 21, 1871.

To all whom it may concern:

Be it known that I, JOHN F. BRONSON, of

Waterbury, in the county of New Haven and State of Connecticut, have invented a new and valuable Improvement in Printers Galleys and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this spec ification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a top view of my galley, with longitudinal clamp-screw. Fig. 2 is a vertical longitudinal section.

This invention has relation to an improvement in galleys for printers use; and it consists in the construction and novel arrangement of the jointed and pivoted arms which connect the side of the galley and the side-stick with the central or parallel-motion bar.

In the accompanying drawing, A designates the galley; B B, the sides; and C, the end thereof. 1) represents the sidestick, provided with a projection or tongue, 6, which slides in a slot, a, formed in the end piece 0 of the galley. E represents a central or parallel-motion bar, situated between the galley-side and the side-stick. F F represent connecting-arms, which are pivoted at their divergent ends, respectively, to the galleyside and the side-stick, and at their other ends said arms are pivoted together and to the bar E by means of the clamp-screws b.

It should be borne in mind in constructing this galley that the length of the slot at in the end thereof determines the capacity of the galley with reference to the breadth of matter which can be placed therein. The length of this slot also determines the length of the arms F F. These arms, when spread to the greatest extent which the length of the slot will allow, are designed to have an angular position with respect to each other.

As above described, my galley is capable of useful and efficient operation; but sometimes, for greater security, I employ the locking-screw now to be described.

The locking-screw G passes through a slot, a, which extends entirely through the end C of the galley. It is provided with a milled head, and has a shoulder, c, which works against a face-plate secured to the outer side of the end of the'galley. H represents a nut or sleeve hav ing a female screw-thread formed within it, and pivoted or otherwise secured to the bar E; or it may be formed in one piece with said bar. The locking-screw G works within the nut H, and'the efi'ect of its operation is to spread the arms F F thereby forcing the side-stick against the matter in the galley with great power.

I have described the best method of constructing my galley; but it is evident that the arins'F F may be pivoted independently to the bar E at different points along its length. When such an arrangement is used the arms should be placed, alternately, on each side of the bar E, and each arm is required to be secured with a separate clamp-screw. The tongue 6, which slides in the slot or, isusually provided with a cross-piece or head, which keeps it in place and prevents the side-stick from beingforced out of position lengthwise.

' I claim as my invention In a printers galley the arms F F, pivoted at their outer ends, respectively, to the galley-edge B and the side-stick D, and at their other ends pivoted to the longitudinal bar E, substantially as specified.

In testimony thatI claim the above I have hereunto subscribed my name in the presence of two Witnesses.
