the     grods counteract the weight of the cylinder obviating the
possibility of guttering. The cylinder is provided with shoo-
fly fingers, tympan clamp and two reel rods. The tympan clamp is controlled by a powerful spring. It is operated by a pin wrench and
3k.                               when opened remains open until the pressman is ready to close it. When closed, the tympan cannot work loose. The trip is simple and
oi                               conveniently placed. Depressing the trip lever before the form reaches the cylinder throws off the impression. This trip lever can be
51%.                             depressed at any time without injury to the press, and impression can be thrown off and trip locked for any desired length of time; a
icr.                             valuable feature for working up color while the form is in place.
itn                                  The reciprocating motion of the bed is controlled by air springs-simple, effective and noiseless. The compression of the air springs
der                              can be regulated for the different speeds without stopping the press. The air springs are provided with a suitable air release which is
Ns                       operated either automatically or by treadle on belt driven presses, and by treadle only on motor driven presses. This feature will be
cit                              found convenient while making ready and in turning the press by hand. The feed guides and tongues are fastened to the feed board,
which can be lifted at the cylinder edge, making it very convenient for make-ready. Pointed register screws fitting into permanent iron
I                  plate insure the feed board returning to its exact position. The rear half of the feed board lifts by simply turning two buttons to release
on                           it, giving free access to the bed.
.d-                                  The patented improved feed and side guides on feed table can be adjusted with the utmost precision. As far as possible all adjustments
I                  are made with thumbscrews. The mechanism is so perfectly timed that feed guides recede from sheet in exact unison with forward move-
ich  !ment of grippers, an essentiat feature for close register and a notable improvement over other makes. The feed guide rod is square, making
ai                              it possible to shift the feed guides to the right or left without effecting the register. The side guide has a variation of several inches
without the necessity of changing to another hole in feed board. Holes are provided clear across the board so that side guide can be used
ng                       either right or left hand.
ii                         The press is provided with rack, cam and table distribution. The four two-inch distributing rollers, set parallel to the table, are
Ir      I                        vibrated in pairs in opposite directions. The two three-inch form rollers clear the form at each end of the stroke. The gear driven
so                       steel vibrating roller vibrates in one direction during the forward stroke and in the opposite direction during the backward stroke of the
bed, reversing when form rollers are off the form. This prevents all danger of imperfect inking from end play of form rollers. Sockets
nd                       are provided above the vibrating roller so that one of the two-inch distributing rollers can be used as a rider roller, which further
enhances the inkingr efficiency. Suitable rests are provided for supporting the rollers off the form and ink table while the press is at rest.
A                        The fountain is easily accessible and can be adjusted while the press is running. The uniform flow of ink can be increased or decreased
to a nicety, or shut of entirely, by a simple movement of the controlling lever. Printed side up (carrier) or printed side down (fly)
he                               delivery will be furnished at option of the purchaser. Either style gives a positive and unfailing delivery of sheets. On the Printed side
ad                            up delivery three printed sheets are constantly exposed to the air, making it possible to carry a strong color without offset. Printed side
its                      (down fly) delivery will be furnished unless otherwise specified on order.
jWith each press is furnished: hard packing, muslin drawer sheet, one set of composition rollers, extra set of roller cores, a five-wheel
3counter, jogger, wrenches, screw driver and oiler. The jogger can be used either as a jogger or as an ordinary delivery board.. It is
noistess in operation and the wing boards can be easily adjusted in a moment without the aid of wrench or screwdriver. Provision is
rmade for the convenient removal of the printed sheets from the jogger. The material entering into the construction of the Stonemetz is
I                  selected with the utmost care and is the best obtainable. Steel is used wherever it is necessary.
