1, ALEXANDER BEAUDRY, of 70, Kilby Street, in the City of Boston and State of
Massachusetts, United States of America, Mechanical Engineer, do hereby declare
the nature of my invention for "IMPROVEMENTS IN MACHINES OR PRESSES FOR
PUNCHING, SHEARING AND OTHERWISE WORKING METALS" to be as follows:-
My invention relates to that class of metal-working machines which have recipro-
cating rams constructed to carry punches, shears, dies and similar tools, and which
operate on the metal placed on a bed or stationary die under or in front of the
ram; and the first part of my invention has for its object to provide a convenient
means of modifying the stroke of the ram, and of wholly disengaging the ram from
its operating mechanism when desired. The second part of my invention relates to
improvements in the die-holder and shoe.
I usually mount two or more rams in one machine, so that one may be used for
pressing or swaging the metal, another for shearing, another for punching, and
so on.
A
So far as relates to the first part of my invention:In a strong cast iron frame I
mount the crank-shaft, and I drive this shaft through gears from a main driving
shaft in the same frame. The ram is mounted in guides in this frame, usually to
play vertically. The ram is not coupled directly to the connecting rod, but said rod
is coupled to a slide block, which plays in a longitudinal bore or way in the ram.
cross-slide mounted in keepers on the ram is adapted to be moved in over the top of
said slide-block, so as to compel the ram to partake of the upward movement of said
slide-block, or to be moved out so that said slide-block may reciprocate freely without
moving the ram. The ram carries a suitable tool at its lower end, and is measurably
counterbalanced by a spring or weight; so that when disengaged, it may be drawn
down and held in place by suitable means. The lower end of the slide-block is
bevelled, and there is a cross-mortise in the ram, wherein is mounted a transverse
slide with a bevelled surface. When this transverse slide in the ram is drawn back
or out, the downward movement of the slide-block does not depress the ram; but
1

page_text: when this transverse slide is pushed in to its fullest extent, the bevelled end of the
slide-block bears thereon and the ram must partake in full of the movements of said
slide-block.
The transverse bevelled slide is operated by the foot of the workman through the
medium of a treadle, rod and chain. In one lateral face of the transverse slide is a
straight vertical groove, and in this groove takes a crank-pin on a crank rotatively
mounted in suitable lugs on the ram. By a half revolution of the crank, the
transverse slide is moved in one direction to its fullest extent, and by a half revolu-
tion in the other direction said slide is moved back. At each end of its stroke the
crank is on
center," and no downward pressure on the bevelled face of the slide can
move it. To impart a half revolution to the crank so as to move the slide out, I
employ a coiled spring embracing the crank-shaft; to drive or move the said slide
in, the chain from the treadle is wound around and secured at its end to the crank-
shaft. Pressure on the treadle drives the slide on; and when this pressure is relieved,
the spring retracts the slide.
I may use known equivalents for these mechanical devices for operating the
transverse slide.
So far as relates to the second part of my invention:-My object is to provide the
press or machine with a stationary or counter die or tool-holder that may be con-
veniently and quickly adjusted up or down, right or left, forward or backward. To
effect this, I form a recess in the machine-bed below the ram, mount a slide-wedge in
same with a screw to move it in or out, place a bevelled shoe on said slide-wedge
having a groove formed in it to receive the die or tool-holder, and mount the latter
in this. Set-screws are provided to fix the parts in place. The slide-wedge secures
vertical adjustment The shoe is square, and may be turned quarter way round so
that the groove for the tool-holder will run either from right to left or from front to
back. Thus the tool or die may be adjusted quickly in any way desired.

I, ALEXANDER BEAUDRY, of 70 Kilby Street, in the City of Boston and State of
Massachusetts, United States of America, Mechanical Engineer, do hereby declare
the nature of my invention for "IMPROVEMENTS IN MACHINES OR PRESSES FOR
PUNCHING, SHEARING AND OTHERWISE WORKING METALS," and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:-
My invention relates to that class of metal-working machines which have recipro-
cating rams constructed to carry punches, shears, dies and similar tools, and which
operate on the metal placed on a bed or stationary die under or in front of the ram.
The first part of my invention has for its object to provide a convenient means of
modifying the stroke of the ram, and of wholly disengaging the ram from its
operating mechanism when desired. Means are also provided for automatically
loosening the fly-wheel so that it may rotate on its shaft in case of the sudden stoppage
of the latter, as by an accident. The second part of my invention relates to improve-
ments in the die-holder and shoe.
There may be one ram or several rams arranged to be operated from one shaft in
common. In the present case I have shown two rams and their appurtenances in
a gang.
In the accompanying drawings which serve to illustrate my invention,―
Figure 1 is a front elevation of one of my machines, and Figure 2 is a vertical
section or sectional elevation of same taken on line 2, 2, in Figure 1.
Figure 3 is a sectional plan of the ram and its appurtenances on a scale double
that of Figures 1 and 2, and Figure 4 is a side view of the same on the same scale
as Figure 3.

is a sectional view of the coupling-slide, on a scale double that of
Let A represent a strong frame or bed-piece, provided with uprights A', cast
integrally therewith. These uprights are connected by tubular ties A³, in which are
provided journals for a driving-shaft B. In the heads of the uprights A' are formed
bearings in which is rotatively mounted a crank-shaft C, which is driven from shaft B,
through the medium of a pinion B', on the latter, and a spur-wheel C¹, on the former.
D is a fly-wheel on shaft B, and E are tight and loose driving pulleys on said
shaft.
F, F, are the two rams mounted to play in vertical guides G, G ; as the rams and
their accessories are substantially alike in construction a description of one will serve
for both.
C' is a crank in shaft C, and to this crank is coupled a connecting-rod_H, the
lower end of which is coupled to a pin i, in a cylindrical coupling-slide, or sliding-
block, I, (seen enlarged and detached in Fig. 5), which fits and plays in a bore or
way in the upper part of ram F. Mounted on the top of the ram, (see Fig. 3), is a
plate J, which is mounted on the ram in undercut or dovetail guides, j, so as to slide
forward and back, when actuated by a suitable knob or handle j¹. This plate J is

page_text: forked, and is provided with inside shoulders, 3, on its branches which, when the
slide-plate is pushed in, take over the upper end of the sliding-block I; but when
said slide plate J is drawn out, room is provided for the block I to draw out from the
ram between the branches of said plate J. The purpose of this device is to enable
the ram to be conveniently disengaged from the reciprocating mechanism for reasons
that will he hereinafter explained.
Through the ram F is formed an aperture extending transversely from front to
rear, the upper face of which is inclined, and into this transverse aperture opens the
mortise or way in which the slide I plays. The lower end of this slide I is bevelled
or inclined, the inclination of the bevel being the same as that of the incline of the
upper face of the transverse aperture in the ram.
K is a transverse slide, with an incline formed on its upper face corresponding to
that on the upper face of the transverse aperture in the ram, and this slide K is
mounted in a suitable guide or guides at k. The slide K in the ram is free to play in
and out under the coupling-slide I.
L is a spring, secured to the tubular tie A, and its free end arranged to take under
a shoulder on the ram. This spring is designed to counterbalance the weight of the
rain and its accessories, but a weight or weighted lever may be used as well.
The operation, so far as described, is as follows:-Shaft C being set in motion, the
connecting-rod H imparts an uniform reciprocating motion to the coupling-slide I.
If the plate J be set as in Figs. 2 and 3, and the transverse slide K stands at the
forward end of its path, then the ram F must partake in full of the movement of the
slide I, as the latter will be closely embraced between the said slide-plate J and
transverse slide K, and no vertical play of slide I, independently of the ram, will be
permitted. Now if the transverse slide K be moved back to the other end of its
path, (as seen in Fig. 2), the coupling-slide I will find nothing below it in the path,
and it will merely play up and down in the ram without the latter partaking of the
movement. The spring L will support and uphold the ram. If the transverse slide K
be moved only part of the way back, the slide I will act on the ram to depress it only
at the latter part of the downward movement of said slide, the whole extent of
movement of the ram being then equal to the whole extent of movement of the
slide I, less the space left below slide I at the end of its upstroke by the displacement
of slide K.
If the operator desires to lower the ram at any time, or stop its movement, for the
time, in order to adjust the die or tool it carries, he draws plate J out or forward by
means of the handle thereon, and this allows slide I to play freely through said
plate. Thus the ram is practically uncoupled from the crank, although the proportion
of the parts will usually be such that the slide I will never be wholly withdrawn from
the ram, no matter what may be the respective positions of the parts.
The transverse slide K is actuated by mechanism that I will now describe, premising
that the said slide is carried by the ram in the reciprocating movements of the
latter.
M is a provision formed on, or secured to, the back of the ram in which is
rotatively mounted a crank-shaft, n, which engages a vertical crank-slot in the rear
end of slide K. The throw of this crank equals the travel of said slide; and when
the crank is on its horizontal centers, the slide will be at the respective ends of its
stroke. On the projecting end of the crank-shaft is secured a pinion, m, which gears
with a rack, o, mounted to play in guides on the ram. Mounted on the frame of
the machine is a slide-plate p, which has a long fork, that engages a stud, g, on the
rack, (see Fig. 4,), so that slide-plate p may be reciprocated by a bell-crank, r,
connected with a treadle N, by a rod s, and the rack be thus caused to move slide K
back and forth. The operator effects and controls this movement of slide K by his
foot, a spring t, serving to retract the parts when he removes his foot from the
treadle.
The long fork in the slide-plate p allows the ram to move up and down without
disengaging the stud
9.
If the workman depresses the treadle N far enough to move the slide K inward,

page_text: For
say to half the extent of its full movement, the ram will then have imparted to it a
movement equal to one-half that due to crank n. In this case, as the said crank
will then stand at right angles to the line of thrust, the operator is enabled to control,
with his foot the pressure of the punch or other tool carried by the ram.
example, if there is a punch in the ram, the workman may adjust the plate to be
punched on the bed or anvil as nearly as he can, and then depress treadle N gradually,
thus setting the ram in motion with a gradually increasing stroke; as the punch thus
nears the plate, the workman is enabled to adjust the latter to the punch. If the
punch should strike the plate no harm will be done as the resistance thus offered will
drive back slide K and the punch will not penetrate the plate. When the adjustment
of the plate is thus perfected, the workman depresses the treadle to the full extent
and the punching is effected.
If the punch or tool "sticks" in the plate after the punching operation, the
engagement of slide I with plate J will serve to withdraw it, as this engagement
compels the ram to rise with the said slide I.
When the ram is disengaged from the slide I by withdrawing plate J, as has been
described, the ram may be drawn down to the desired extent, and when down may be
temporarily held in that position by a set-screw or other equivalent means.
I contemplate, for convenience of operation, arranging two, three or more rams in
one series or gang, and providing one with shears for shearing metal, another with
a punch, and another with a press, die, or "former" for shaping or swaging the
metal.
In Fig. 1, I have shown the guide k, on ram F, arranged at the side of the
transverse slide K, and on ram Fi on the underside of the said slide K. Either
construction may be employed, or any good form of keeper or guide may be used.
In Figure 1, I have broken away the fly-wheel 1) and a part of one of the
pulleys E, in order to show how the fly-wheel is mounted on shaft B. On this shaft
is a collar, u, and a tapered portion which fits into the eye of the fly-wheel; and
exterior to the fly-wheel is cut a left-hand screw, v. A nut, w, serves to force the
boss of the fly-wheel up snugly on the taper and thus fix the wheel on the shaft.
If the shaft should be suddenly stopped by some impediment the tendency of the
fly-wheel to continue its revolutions will act by friction to unscrew nut w and thus
set the fly-wheel loose on the shaft and permit it to revolve freely without injury to
the machine from its great momentum. When the obstacle is removed the nut may
be again screwed up tightly.
The second part of my invention relates to the adjustable shoe and tool or die-
holder, and this feature is illustrated in Figs. 1 and 2.
In the bed A* of the machine is formed a rectangular recess, which is dressed or
planed out to receive a forked wedge, 1, which may be driven in or withdrawn by a
collared screw,
2. On this wedge rests the shoe, 3, provided with a slide-way in its
upper surface to receive a tool-holder, 4. In the sides of hed A* are driven set-
screws, 5, to hold the shoe 3, firmly when the vertical adjustment has been effected ;
and in the sides of the shoe 3 are driven set-screws, 6, to secure the holder 4 in
position after the horizontal adjustment has been effected. In Figs. 1 and 2, the
tools, 7, 7, one carried by ram F and the other carried by holder 4, are shears.
any suitable tool may be employed, and any suitable form of holder 4 may be used.
Holes or coinciding apertures 8, 8, are formed in the bed Ax, the shoe 3, and the
holder 4. These allow for the passage of a punch or other tool. They are not
absolutely essential.
But
In order to illustrate more fully the adaptation of my invention, I have shown the
shoe under ram F', in Fig. 1, as unprovided with a lifting-wedge, and have shown
the holder 4 arranged to be adjusted or moved in a direction at right angles to that
shown with respect to ram F. There may be two wedges under the shoe, if desired,
and in some cases I prefer this arrangement.
I do not wish to limit myself to the precise construction herein shown, as this
may be varied to some extent without any material departure from my invention.
For example, as before stated, a weight may be substituted for spring L as a counter-

page_text: balance for the ram. I have shown the ram arranged to play in a vertical path, but
it may move in an inclined or horizontal path. Other devices may also be employed
to compel the ram to partake of the upward movement of sliding-block I. The
forked slide J, is, however, a convenient and simple device. In Fig. 3, represents
a stop-screw to limit the movement of the plate J when it is drawn out. The
head of this screw engages a slot (see dotted lines) in the underside of plate J.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
First. The combination, with the ram, mounted in guides, of the coupling-slide,
