Year: 1888

page_text: I, WALTER SLICER JARBOR of Pittsburgh in the County of Alleghany, State of
Pennsylvania, United States of America, Mechanical Engineer, 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 :-
In two Letters Patent one of Great Britain Nod. 10631 year 1887 & the other of the
United States No. 367,637, granted August 2nd 1887, I have described a package
wrapping machine, wherein the paper which is to form the wrapper, is intermittently
fed to a pair of shears, which cut off a sheet of a size adapted to enfold the article to
be wrapped, the sheet so cut off being then manipulated and automatically folded over
and around, and in at the ends of the article being wrapped, by means of certain
peculiar mechanism, and moving parts, operated from a common shaft.
My present invention has relation to package wrapping machines, and is designed
as an improvement on the machine described and shown in my aforesaid application
for letters patent, and embraces many of the essential features of that application,
as well as certain new and novel features, which will be hereinafter fully described and
claimed.
In the following description I will refer as briefly as is consistent with a full and
clear understanding of my present invention, to the portion of the apparatus already
described and shown in my before mentioned two several Letters Patent, and will
more specifically describe those parts which I believe to be new.
My present invention has for its object the provision of novel means for auto-
matically wrapping packages or blocks of solid material, in paper or other flexible
material.
My invention has for its further object, the provision of means for automatically
wrapping articles packages or blocks of solid material, in a double wrapping of
paper or other flexible substance, that is, two separate sheets or sections of paper or
other suitable material one over the other, at a single operation.
My invention has for its still further object, the provision of means in a package
wrapping machine, for readily adjusting the machine to wrap packages, blocks, or
articles of different sizes.
My invention has for its still further object, the provision of novel means com-
prising the peculiar construction combination and arrangement of parts hereinafter

page_text: described, for more rapidly accurately and neatly enfolding and wrapping packages,
than has heretofore been possible.
.
My invention therefore consists in the construction, combination, and arrange-
ment of parts more fully described hereinafter, and specifically pointed out in the
claims.

embraces the folding appliances, Fig. 15, is a transverse sectional view on enlarged
scale, of the upper part of the machine on the line 2, 2, of 14; Fig. 16, is a series of
views representing a package in different stages, while being enfolded.
A, designates the table, upon which the working parts of the machine are mounted,
and a, a, a, the legs supporting the same, B, designates the main or driving shaft of
the machine, suitably journaled in bearings b, b, sustained by the legs a, a, and
carrying the cam wheels B1, B3, the mutilated gear wheel B³, and the band wheel B*,
through which and a crank B5, on the end of the shaft, motion is communicated to
the working parts of the machine.
Upon vertical arms c, c, and horizontal arms c¹, c¹, at one end of the table A, are
respectively journaled two rolls, or reels of paper or other material, suitable for
enfolding the article to be wrapped, said rolls or reels being lettered C¹, C', and
sustained on shafts c³,
The strips of paper or other wrapping material from the rolls C, C₁, are
designated d, e, and each strip passes through a pair of feed rolls, constructed and
operating in the manner of the feed rolls employed for, a like purpose in my before
mentioned letters patent, that is, each pair of feed rolls consists of a large roll, inter-
mittently operated by means of a dog upon a reciprocating arm, taking into teeth
upon a wheel, fixed on the shaft of the roll and a spring stop e', and a smaller roll
mounted in an elastic bearing; the paper passing between the rolls and being fed
positively but intermittently forward, by their motion. D, designates the upper and
smaller feeding roll for the strip d, journaled in bearings D¹, D', rising from the
table A, the journals of said rolls, being pressed upon by springs, fitted in
sockets d', d; and D, designates the lower feed roll, mounted on a shaft d², that is
journaled in hangers d³, d³, on the bottom of the table A. The shaft, projects
beyond the hanger on one side; and to the projecting end of the shaft, is secured a
wheel D³, having teeth d', d, d, d, with which engages a spring dog d³, on an
arm, loosely mounted on the shaft. The end of the arm de, is pivotally attached to
-the lower end of a vertical rod d', which is pivotally attached at or about its middle
to a curved pitman rod s, connected at its other end to the crank B, on the end of
the main driving shaft B. E, designates the larger feeding roll for the strip e,
mounted on a shaft e, journaled in standards E', E', and having a wheel E³, with
teeth e, e, e, e', a pivoted arm e, carrying a dog e, and pivotally secured to the end
of the vertical rod d. E³, designates the smaller feed roll of strip e, journaled in the
standards E', E', and sustained on springs in sockets e, e'. The feed roll D², of tho
strip d, is it will be observed somewhat larger than the feed roll E, of strip e, and by
reason of this difference in the size of these rolls the strip d, will be fed forward a
somewhat greater distance than the strip e, at each downward movement of the
-vertical rcd d'.
The several rolls D, E. D', E³, are grooved, and guiding wires f¹. fl. ƒ', ƒ¹, and on

page_text: frames F, and F, projecting through the grooves, serve to guide the strips d, and e,
to the cutting shears. G, designates the stationary blade of the shears fixed on a
standard G; and Gs, designates the movable blade of the same, which is fixed on a
rock shaft G³, that is journaled in the standard G', and in a standard G, a lever G³,
is secured to the rock shaft G³, near the standard G*, and through said lever, the rock
shaft receives motion from a vertically moving portion of the folding devices.
Having thus briefly described the device for feeding the wrapping material, I will
now describe the frame work of the wrapping devices, and the manner in which the
same may be adjusted to accommodate articles or packages of different sizes, and will
then describe the moving parts of the wrapping devices. H, H, H, H³, H³, H³,
designates six posts or pillars rising from the table A, and jointed together by cross
pieces, h, h, upon top of the cross pieces h, 1, 12, are laid two "T" irons I, I,
which extend from the shears to near the end of the table A. These two irons are
secured upon top of the cross pieces, by means of laterally projecting flat strips i, i,
having slots,, near their ends, through which pass screws 1, 2, that rise from the
standards H, H, and H', H', fitted with thumb nuts ³, ³. By means of the slotted
strips i, i, and the thumb nuts 3, 3, the distance apart of the irons I, II, may be
readily adjusted and fixed, and as these irons support and carry the adjustablo portions
of the frame work of the wrapping devices, the whole adjustment of the frame is
accomplished by loosening the thumb nuts, and moving the irons I, 1¹, together or
apart.
From each of the irons I, I, near the rear end of the same, depend two vertical
posts K, K. K', K', and to the insides of these posts, are secured two metallic
plates K, K', whose forward ends are spirally curved, the curvature of the ends
serving as will presently appear, to from the last fold of the wrapping material upon
the article or package, and the straight portions of these plates, from the sides of the
chute or passage through which the wrapped articles are delivered from the
machine.
K², designates a wide flat plate, placed horizontally between the vertical
plates K, K, and forming a part of the top of delivery chute above referred to.
The plate K2, has a wide upturned end K³, the lower edge of said plate being rounded
off as shown, and this upturned end serves as a shield and stationary folder, acting
to fold down the horizontal flap of the wrapper, as the article is pushed under said
plate. To the plate K³, are secured two cross bars K³, K³, slotted near their ends,
and having uprights K, K, which fit into tubular sockets k, k, on the under side of
the cross pieces 1, 1. Spiral springs may be arranged within the tubular sockets ko, ko,
and the said sockets and spiral springs serve to guide and sustain the top of the
delivery chute, and permit the same to give, if any of the articles passing there-
through should be thicker than the others. To the said cross bars K³, K³, are secured
by screws ko, ko, passing through the slots in said cross bars, two plates ke, k, which
extend from just in the rear of the upturned end of the plate K², to the rear end of
the same. Upon top of the plates k, k, are pins h, k, which pass through holes
in lateral arms ka, k, on the standards or posts k, k, k², k².
!
Upon a line with the curved ends of the vertical side plates K', K', and affixed to
the edges of the plates ke, k, are two vertical ears 2, 2, having their forward ends
curved outwardly, and their lower forward corners turned up slightly, said ears acting
to turn in the last angle fold of the wrapping material, as shown at 4 Fig. 16.
The frame work of the wrapping devices above described, is capable of being
adjusted to accomodate different sized articles or packages as follows.
The thumb nuts 3, 3, and the screws k³, k, being loosened, the irons I, I, may be
set farther apart or closer together, in their movement, carrying with them the vertical
side plates K', K', and the plates k, k, thus increasing or diminishing the width of
the delivery chute accordingly, as said irons are moved closer together or farther
apart.
The web of the irons 1, 13, is turned in near the forward end of the same, and upon
the outside of the web on each side is secured a block of metal L, which is sub-
stantially triangular in cross section. Upon top of the block L, is secured an arm 7,

page_text: which projects upward and outwardly, and to said arm is attached a spring P, to the
other end of which, is secured a plate of metal 1, that passes through a slot 1, in the
web of iron I. A pin 1, is fixed in the slanting under side of the block L, and in
one position of the plate 13, as in Fig. 6, its outer edge bears against the said pin.
The plate 13, has a pin 16, on its bottom, that passes through a triangular or wedge
shaped slot m, in the head m³, of a sliding plate M. This plate M, lies and slides upon
the outside of the iron I, and is held in position by a screw m², that passes into the
web of the iron and through a slot m³, in a vertical flange m', near the end of the
plate.
Upon top of the flange m³, and at each end of the same, is a lug m³, m³, and a
cross head N, upon a horizontally reciprocating rod, N¹, contacts with these lugs
alternately, thus imparting an intermittent reciprocating motion to the side plates M
on each side.
The plate, has a certain amount of lateral play in the slot 1, and is capable of
turning on the edge of said slot as on a pivot when its inner and lower edge is
pressed upwardly, and by this movement the plate is disengaged from the pin 15, and
when so disengaged, the spring 12, draws the plate back until its inner edge is just on
a line with the inner edge of the slot 1. The two positions of the plates 1³, 13, are
best seen in the detail views Figs. 6 and 7, and the manner in which the same are
operated is as follows: The plates 1³, 13, being in the position shown in Fig. 6, receive
and sustain the package to be wrapped until such time as a table T, which rises up
under the plates 1, 1, at certain regular intervals, contacts with said plates, and lifts
their inner edges. This causes the plates to become disengaged from the pins 1º, and
they fly back into the position shown in Fig. 7, thus allowing the article to rest upon
the wrapping material which projects over said table. The table T, and the plates I³, 13,
are restored to their former position by the backward motion of the side plates N,
the triangular slots m, acting upon the pins 1, and forcing the plates out through the
slot, and until their rear edges again engage with the pins 1, 1°.
O designates a flat horizontal apron, which is placed in the rear of the pivoted
plates 1, 1, and is secured to the inner edge of the "T" iron on one side, projecting
through an opening in the web of the iron on the other side, and beneath the bottom
of the chute p¹. P, designates a second table which rests upon the cross pieces h¹, h³,
and has a central rectangular cavity p, that lies under ends of the irons I, I. This
table P, serves to receive and sustain the wrapping material as it is fed forward from
the rolls; and at the side of the cavity p, are arranged adjustable guides p', p',
which hold the paper in position over the cavity p, while the table T is ascending.
In order to prevent the paper or other wrapping material from sagging down into
the opening p, in the table P, I provide two wire forks p, p, which extend over said
opening, while the paper is being fed forward, and which are turned out of the way
by appropriate mechanism when the paper is in proper position. These wire forks are
fast to the tops of upright rods p³, p, which are swiveled in the block p', to which is
hinged the first of the hinged plates which effect the folding of the first flap of the
wrapping material over the top of the article.
These rods p, p, are square in cross section, and are each given a quarter turn, so
that they form spirals, and they pass through square holes, in arms p³, po, projecting
from a cross bar p, which is secured to the tops of vertically reciprocating rods,
which carry the racks operating the folder Q, the result of which arrangement is that
upon the downward movement of the cross bar p', the wire forks p², p², are turned
aside from over the opening p1, and upon the upward movement of the same, the wires
are restored to their original position.
One of the features of the present device to which I will here call particular atten-
tion is that the weight of the article to be wrapped, is utilized to effect a portion of
folding of the wrapper and this is effected by having the article descend through the
opening p, in the plate P, taking down with it the two sheets of wrapping material
which have been previously cut from the strips d, and e, and folding up the sides of
the same against the sides of said opening. The table T, which has been previously
referred to and described as ascending beneath the plates 13, 13, and after operating the

page_text: same receiving the article to be wrapped and the wrapping material; consists of a flat
plate mounted upon a vertical post or standard t, that is connected by a pitman t³,
with the gear wheel t, which receives motion from the mutilated
in the machine
described in my before mentioned patent, operated the tilting through and its
plunger.
shaft B, the table being thus operated by the same mechanism w B, on the main
It being premised that the folding devices are substantially the same as those
described in my aforesaid patent, it will be unnecessary to particularly describe the
same, but I will now describe the means whereby said folding devices may be
adjusted to operate upon packages of different sizes.
It will be seen that what I call the end wing folders which are marked R, R, in the
drawings, are hinged to a skeleton frame composed of the cross bars R³, R³, and
vertical rods R, R*, which reciprocate through holes in the table, the cross bar R³,
carrying an anti-friction roller, which travels in a cam groove $8, in the wheel B¹
Another and similar frame composed of vertical posts 2, 3, and cross bar U, the latter
carrying a roller, which engages with a cam groove, in the wheel B³, is provided
at its upper end with the vertical racks 8, 8, which engage with toothed segments S, S,
fixed to the pintals of the folding wings R, R, which latter are operated by the engage-
ment and co-operation of the racks and segments, while the frames are operated in a
differential manner under conditions and for the purpose designated in my patent
already referred to.
The rock shaft G', which actuates the shears, receives motion from the frame R2, R³,,
through a vertical rod g, connected to the bar R³.
In Fig. 8 of the drawing, I have illustrated the end wing folders, and the means
for adjusting the same. The said end wing folders which are lettered R, R, are
hinged to sliding blocks dovetailed into slots in the plate r³, and having on top
and at their inner ends, lugs 2, 3. The plate r¹, is formed with a piece, which is
in line with the lugs, ; and the lugs 2, 72, are formed with reverse screw threads
so as to receive a right and left screw 4, which passes through them, and through the
piece. The screw turns in the piece, without travelling, and a jamb screw ro,
serves to fasten the screw, when the proper adjustment has been secured.
As the toothed section S, S, by means of which the plates R, R, are turned, are fast
on the pintle of said plates, it is necessary to provide, for the difference in position of
the same, and accordingly I mount the racks s, s, with which the sections engage
upon arms s¹, s¹, which pass through slots in the head of the vertically movable
rods,, through which said racks receive motion from the cam wheel B¹, and secure
the arms in the slots by means of keys s', s', as shown.
The horizontally swinging side angle folders are constructed and operate substan-
tially in the manner shown and described in my previous application, but are made
adjustable by the following arrangement of devices.
n³.
The folders consist of the horizontally swinging arms W, W, which are secured at
their outer ends to short vertical shafts n, n, which pass through slots a, a, in table A,
and are journaled in blocks n², n', which move in dovetailed grooves in the table, the
said blocks being adjustable towards, and from the edge of the table, by screws n³,
To the lower ends of the shafts n, n, are secured arms n³, n³, which have friction
rollers n, n, that work in slots no, no, in a frame W₁, which is mounted on a horizon-
tally reciprocating rod W2, which receives motion from the cam, on the periphery of
the wheel B¹.
The rod W, is utilized for the purpose of giving motion to the rod N³, which carries
the cross head, and the plunger N³, projecting out beyond the end of the table A, and
connected to said rod by a frame W³. Operation
The article to be wrapped, which is, for instance, a cake of soap, is fed to the
table O, by the chute P₁, and is slid forward upon the supporting plates 1, 1, by the
plunger N. At the same time the two strips d, e, have been fed forward, (the lower
strip a somewhat greater distance than the other,) below the cake of soap a proper
length cut off by the shears. The forks p², p³, have been utilized to sustain and guide
the wrapping material, and are now turned aside out of the way. The table T, arising,

page_text: releases the plates 13, 1, and the soap and the wrapping material descend and rest upon
the table T. The latter now descends, and the two sides of the wrapper are folded up
into vertical position as seen at Fig. 16, by contacting with the sides of the
opening p, in table P. The table T continues its descent until its surface is level
with the surface of table A. The folder Q now comes into play, and folds down
the wrapping material at one side as seen at 2, Fig. 16. A plunger V, that
receives motion by means of V₁, from the cam upon the periphery of cam wheel B³,
now pushes the article along beneath the end K³, of plate K2 and the wrapping
material on the other side of the soap, is thereby folded down over the top, the end
wing folders R, R, now come into play, and the package then assumes the shape
shown at 3, Fig. 16, and then the movable side angle folders W, W, the package
then appearing as at 4, Fig. 16, the article is then pushed still farther under the
plate K, by the plunger, and the stationary side angle folders k², 12 give it the
shape shown at 5, Fig. 16, and the curved ends of the vertical plates K¹, complete
the folding operation. The parts now return to their former position, and the next
article is operated upon in like manner.
The manner of adjusting the several parts of the machine, has been hereinbefore
sufficiently described and need not be repeated.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declaro that what I
claim is.
