WILLIAM BARTLETT, or DERBY, NEW HAMPSHIRE.
FEED-GAGE FOR PRlNTlNG-PRESSES.
SPECIFICATION forming part of Letters Patent No. 452,022, dated May 12, 1891.
Application filed March 15,1889. fierial No. 808,368. (No model.)
To all whom, it may concern.-
Be it known that I, WILLIAM BARTLETT, a citizen of the United States, residing at Derry, in the county of Rockingham and State of New Hampshire, have invented certain new and useful Improvements in Feed-Gages for Printing-Presses, of which the following is a specification.
This invention relates to the registeringgages of a printing-press, and has for its object to provide such a gage as can be quickly and easily adjusted upon the tympan-plate.
The invention will be readily understood by reference to the accompanying drawings, forming an inseparable part of the following specification and claim, of which-- Figure 1 is a plan view of a tympan-plate, showing my improved adjustable guides applied thereto. Fig. 2is an enlarged sectional view of the same.
Similarletters indicate corresponding parts.
A is the tympan-plate, upon which may be placed in the ordinary manner the blanket and the tympan-sheet B, these being secured thereon by the common clamps C.
To carry my invention into practice I may employ a pair of jointed arms for holding the guides to feed to; or with this pair I may also employ a single-jointed arm carrying a guide to feed one side to,
The supporting -piece D is preferably formed of spring brass or steel bent so as to present normally the shape of the usual curve, and upon its top edge is provided an ear d, which is bent at right angles with the part D and perforated for the reception of a screw or rivet E, which also passes through a perforation in one end of the sections F of the jointed arms.
The opposite end of either section F is piv oted by means of screws or rivets fto one end of the sectionsG of the jointed arms, the free ends of which are adapted to carry the guides to feed to. The jointed arm carrying the side guide may have its section F riveted to an independent support D, the latter being placed at one end of the tympanplate A, while the support carrying the doublejointed arms is more conveniently located at the back side of said tympamplate, both said supports D being compressed between the edge of the tympan'plate and a clamp C.
My improved guide, which is secured to the free end of the section G, consists of a fiat base I and a folded portion 1, which stands out from the base, making aV-shaped guide, with the outer portion adapted to be folded down against the base under the gripperwhen the press is in use. The guide is preferably provided with an ear or projection K upon one side of its base or bottom, by means of which it is pivotally connected with the end of the section G. By making the guide movable in relation to the sections F and G it can be adjusted to the various changes of position to which the arm or section and guide must necessarily be putin the different kinds of work done on the press. All the joints are made sufficiently tight to remain as adjusted by friction, and the parts are preferably made of spring metal, and the sections may be slightly curved inward in the usual manner to cause the guide to bear with some force upon the tympan-sheet B and prevent it from being accidentally misplaced.
All of the arms upon the press may be provided with the V-shaped guides, as above described, or some of them may be provided with the ordinary cup shaped guides, as shown at II in Fig. 1, and the V-shaped guides used for the adjustment of the paper in relation to the cup-shaped guides.
Having described my improved devices, what I claim as new, and desire to secure by Letters Patent, is
In an attachment for printing-presses, the combination, with a base or supporting-piece D, of a jointed arm F G, pivotally secured thereto at one end, and a flat guide of folded spring metal I, pivotally secured to the opposite end of the arm, whereby the guide may be adjusted or changed in relation to the arm,
substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
'WILLIAM BARTLETT.
