Improvements in Stapling Machines.
A communication from abroad by AARON FREDERICK SMITH, of 111, Washington
Street, Lynn, in the County of Essex, AUGUSTUS SEAVER, of 28, Stanhope
Street, Boston, in the County of Suffolk, and WILLIAM SAMUEL HAMM, of
22, Pelham Street, Newton, in the County of Middlesex, all in the State of
Massachusetts, United States of America, Gentlemen.
.
I, WILLIAM LLOYD WISE, of 46 Lincoln's Inn Fields, in the County
of London, Consulting Engineer and Chartered Patent Agent, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to certain improvements in stapling machines for fastening
together laminæ of leather, rawhide, or other material, its object being to specially
adapt the machine for the manufacture of belting. To this end, the invention
consists in a novel arrangement of feed mechanism whereby a longitudinal row of
staples may be inserted, and also a transverse row of staples, all of which will .be
fully described hereinafter.
Referring to the accompanying drawings, which illustrate a construction for
carrying out the invention.
Figure 1 shows a front elevation of a machine, which embodies the invention.
Figure 2 shows a top plan view.
Figure 3 shows a longitudinal section.
Figure 4 shows a section on line 4-4 of Figure 2.
The letter a designates the supporting bed of the machine, and b a head which
supports staple-forming and inserting means, the details of which are not here
described, as they form no part of the present invention, and c an anvil which
co-acts with the staple-forming and inserting means.
The belting 2. whose lamina are to be fastened together by the staples passes
over the bed a and is fed through the machine by the following means: a pair of
feed-rolls d d', dd, are located at each side of the machine, and each of said rolls
is preferably formed of a round bar of iron cored out and faced with rubber.
The upper roller of each set is supported in stationary bearings, while each lower
roll is adjustably supported as follows:-
A
A hinged frame e forms a bearing for the roll, and carries at the central part an
anti-friction roller e adapted to yield, and being backed up by a spring
pivoted arm has an inclined projection f' on which said ruller e bears, and said
arm carries a pawl f* pivoted and spring-actuated, and adapted to be operated by a
handle pivoted to the arm f. Said pawl engages a stationary rack, and by
raising or lowering the said arm-which has a handle 7-the pawl may be engaged
with different portions of the rack and the lower feed roll adjusted with respect. to
the upper one.
An intermittent driver is employed to turn the feed-rollers and advance the work
step by step, and this driver and its adjuncts are of the following description.
One of the upper rollers, which is designated d, carries a ratchet y, and an arm g
pivoted on the journal of the roller carries a pawl g engaging said ratchet.
A pitman gl connects a crank-disc g on the driving-shaft g with the pivoted
arm, and through this means the pawl, which is the direct driver, is reciprocated
and the roll turned step by step.
The pawl g is reversible, and may move the roll in either direction. It is fitted
to slide longitudinally in a way formed in the arm g'. and is actuated by a spring 9*
into engagement with the ratchet, its end being bevelled on one side. Notches are

page_text: formed in the arm g', and a pin g' fixed transversely in the pawl engages said
notches, and the pawl is thereby prevented from turning.
A knob 98 in the end of the pawl affords means whereby the latter may be
withdrawn sufficiently to release its pin from the notches, and then turned around
and the pin again engaged with said notches. Under one adjustment of the pawl,
it will be seen that the roll will be moved in one direction, while under the other
adjustment of said pawl the roll is turned in the opposite direction; for under the
first-named adjustment one stroke of the pitman drives the roll, and the other
stroke of said pitman simply slides the pawl over a tooth of the ratchet, whereas
under the other adjustment the reverse is true.
The roll d carries a gear, and is connected through intermediate gears d³ do with
a gear on the roll d³, and through bevel-gears d' d³, shaft d', and bevel-gears dod",
with the roll d'; and the latter carries a gear d¹ and is connected through inter-
mediate gears d¹³ d" with a gear on the roll d³. Through these connections, all the
feed-rolls are operated simultaneously.
The operation of the mechanism thus far described is as follows:-
At this
One set of the feed-rolls, as d and d' (see Figure 3) is thrown into operative
relation and acts to draw the belting 2 through the machine step by step, the
staples being inserted while the pawl g slips over the teeth of the ratchet.
time the roll d is lowered out of operative position. When the longitudinal line of
staples has been inserted, the pawl gis reversed, the roll d is lowered out of operative
position, and the roll d' is brought up against the work. The feed is now reversed
and the belt fed through the machine, and another longitudinal line of staples
inserted. This saves running the work twice through the machine in the same
direction. After the first longitudinal line of staples has been inserted, the staple-
inserting means are shifted to position for inserting a new longitudinal line of
staples through means hereinafter described. Through these means, transverse
rows of staples may be inserted at intervals, and these means will now be
described.
The head is mounted on a carriage which fits slide-ways in the bed a, and
the anvil c is also mounted on this-carriage. The means for reciprocating the anvil
are as follows:-
28
A rock-shaft is supported in bearings on the carriage h, and the anvil rests on
an arm i affixed to said rock-shaft. Another arni affixed to said rock-shaft is
connected by a rod with an eccentric * on a counter-shaft to which a gear
is splined, and said gear is connected through an intermediate gear i7 with a gear
on the driving-shaft g³.
A rack is fastened to the carriage h, and a gear 1 meshes therewith, said gear
adapted to be shifted into and out of mesh with said rack by a shipper, and being
splined on a shaft which is connected through skew-gears j * with the journal of
the roll d.
The bevel-gear 8 (see Figure 2) is splined to the shaft do, and may be thrown
out of mesh with the bevel-gear a by means of a shipping-lever m, which is held
in its two positions by the engagement of a latch me with a stationary projection on
the machine frame. When a transverse line of staples is to be inserted, the bevel-
gear dis disconnected from the gear d'. The roll d' is lowered out of operative
position, and the roll d³ is brought up against the belting and clamps it against the
roll d, and the belting is held stationary, for these rolls d and d³ no longer revolve.
The gear is thrown into mesh with the rack i, and is moved step by step through
its connections with the roll d..
The invention may be embodied in different forms than here shown, and is not,
therefore, limited in this respect.
Having thus described and ascertained the nature of the said invention, and in
what manner the same is to be performed, it is declared that what is claimed is:-
1. A machine of the character described, comprising in its construction two sets
of feed-rollers at opposite sides of the machine, one roller of each set being
