Description
@uiten tatra atent @ffice BNJAMIN O. WOODS AND WILLIAM S. TUTTLE, BOSTON, MASSACHUSETTS,
Letters Paten-t No. 67,475, dated August 6, 1867.
PRINTING-PRESS.
'.lO ALL WHOM I'L MAY CON CERN:
Beit known that we, BENJAMIN O. WOODS and WILLIAM S. TUTTLE, both of Boston, in the county of Suifolk, and State of Massachusetts, have invented certain new and useful improvements in Printing Presses; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings 'and to the letters of reference marked thereon.
Figure 1 of the drawings is a perspective view.
Figure 2 shows the lower attachment of the secondary toggle-joint lm at to the bed-plate or framework of the press.
Figure 3 shows the device for adjusting the tympan.
Like letters refer to the same or corresponding parts in all the gures.
A is the framework or bed-plate, having attached the form-receiver or bed b. c is the tympan, and has the arms d attached. These arms al are pivoted to the crank-arms e, which also are pivoted to the bed-plate or framework, (seef.) 'lhere are two of these arms, and corresponding parts, 'one arranged at each end of the tympan and each side of the press, and each crank-arm is furnished with an adjusting-screw, g. The turning Y of these screws g in one or the other direction throws the lower part of the tympan outward or inward, as the case may be, toward or from the plane of the type-bed b, and consequently furnishes the means for bringing them into position parallel to each other at the time the tympan is thrown into position to receive animpression. This arrangement furnishes a more perfect facility for accurate adjustment by the two screws than is usually attained with four or more screws, 82e., and constitutes an important feature of our improvement. A ltoggle-joint, 7L z', is jointed to the bed-plate or framework of the press at j, and to the tympan c at k. It will be noticed that by throwing the centre hinge of this toggle-joint in the direction of pins f, so as to bring the parts h z' to approach a line of coincidence, the tympan will be thrown toward the form-receiver or type-bed, while in the position shown in iig. l it has receded from it. Jointed to thefirst togglejoint h i', is a second one, m n, one end being attached to the-hinge of the iirst joint at p, and the other to the bed-plate or framework at q, figs. 1 and 2. A treadle or other rod, s, for working it isjointcd in common with w,its hinge at r. By depressing the rod s the toggle m 'n is made to operate the toggle 7L 'L' and throw the tympantoward thetype-bed b. The weight ofthe tympan returns it to the position shown.
This combination of the two toggles gives a very easy action to the parts, while the .arrangement is such that the parts m s are brought nearly in a common line, and in a line nearly transverse to the line formed by h z', at the pointof movement when the impression takes place, so that the full elfect of the toggle z' is realized at the point of impression, and still an easy and approximately equalized movement is secured in the-early part of the action. Other points in the construction, as well as thematerial, not already described, need not differ materially from other presses of the class Having therefore described our improvements, whatwe claim as our invention, and desire to secure by Letters Patent, is as follows:
Claim.
1. We cla-im adjusting the tympan, with reference to the type-bed, by appliances at w, the lower end of arms d, without intending to limit ourselves to the particular appliances shown, substantially as described.
2. The arrangement ofthe crank-arms e and screws g in combination with the tympan and bed-plate, substantially as described.
