Specification Accepted, 25th Feb., 1887.
I, THOMAS EDWARD KEAVY, of the Incorporated Village of Kent, in the County of
Portage, and State of Ohio, in the United States of America, Machinist, 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 has relation to improvements in that class of button locating
machines in which a number of points bearing the relative positions desired for the
buttons, are arranged to be simultaneously forced upon the material to be marked.
It also has relation to improvements in devices of the character aforesaid wherein,
knives, being substituted for the marking points, cut by a single operation shoe-flies
and button-holes therein.
The object of this invention is to provide devices whereby the results hereinbefore
referred to may be more readily and perfectly accomplished; and to facilitate the
adjustment of said machine to different sizes and styles of shoe-flies.
The invention consists in the devices illustrated in the accompanying drawings, as
hereinafter described and specifically claimed.

Figure 14 a side elevation of Figure 13.
Figure 15 a modified device for binding the spring and
Figure 16 an elevation of the device shown in Figure 15, with part of the head.
Referring to Figures 1 to 8, the operative parts of said machine are connected with
a head, A; one face of which is plain, and from the other projects a collar by which
it can be attached to a press shaft, a part of which, N, is shown.
The apparatus is adapted to be used with any suitable press which has a vertically
reciprocating shaft to which it can be attached, and by which it can be forced upon
and withdrawn from a table which holds the material to be cut or marked, and, as its
operation is obvious, no press is shown.
Attached to the lead, A, by means of two arms, F, pivoted on two posts, G, is a
straight band spring, B, which is forced from its normal line by the screw, L,
meshing in a screw-threaded lug on the head, A, and turned by the land-wheel, M.
A series of posts, C, preferably cylindrical, and each provided at its lower end with
devices for holding a marking instrument, e, (as shown in Figure 4) or cutting tools
(as shown in Figures 5, 6, and 7), are mounted on said spring by means of longi-
tudinal cuts from their upper ends adapted to fit said spring: said upper ends above
said spring being closed by nuts, c.
By this construction and arrangement cach part can be at any time removed by
unscrewing the nut, e, without disturbing the other parts of the machine.
The central post, D, is fastened to the spring, B, by a set screw, d, and constitutes
an abutment for the screw, L.
The posts, C, on either side of the central post, D, are at all times equidistant from
each other, and are retained in their respective positions on the spring, 13, or moved
to new positions to adapt them to different curves by a series of levers, E, having
forked or slotted ends enclosing said posts.
These levers are pivoted on two plates, H, which are hinged on opposite sides of
the central posts, D, their outer ends having segmental slots mounted on the posts, G.
The inner ends of the levers, E, on each plate, H, are united by a yoke, J, which
is in turn connected with a thumbscrew, K, meshing in a nut, I, journaled in the
plate, H.
When the spring, B, is forced outward by the screw, L, into a curve of smaller
radius, carrying the inner ends of the plates, H; their ouier ends, sliding by means of
the curved slots on the posts, G, maintain the levers, F, and connected parts in
substantially the same relative position.
The positions of the posts, C, are adapted to the smaller curves, by turning
outward the screws, K, which swing the levers and simultaneously slide the posts
toward the centre.
The pivotal points of the several levers are at different distances from their outer
ends, the ones next the centre post being nearest, and thence by a regular progression
to the outer ones which are farthest; whence, their inner ends being swung the same
distance, by the yoke, J, the outer posts are moved the greatest distance, and each
succeeding post so much less as will constantly maintain them equidistant.
When used as a button locating machine the socket post shown in Figure 3, is
preferably used with the marking point, e.
To adapt it for cutting shoe flies and button holes therein, the part of the post
below the spring, B, is made larger than the upper part, as shown in Figures 5, 6, 7,
and 8, with a semi-circular face extending downward in a thin lip to afford a seat
for the knife; and a narrow flange, f, at its top which constitutes an abutment for the
top of the knife.
Centrally within the bottom is a socket in which rests the button hole knife, k, hell
in place by a screw, s

page_text: Below its sink, which rests in the socket, this kite, k, has a follow tapering body
terminating in a sharp, hollow panch with a straight rearwardly-projecting blade.
Within the hollow of this knife body is a pin, o, which projects slightly beyond the
edge of the punch, and is constantly pressed outward by a coiled spring.
This pin recedes when the knife is forced through the material, but immediately
returns, as the head is withdrawn and pushes the particle of material from the punch.
The fly-knife, P, consists of a thin band of steel, having its lower edge sharpened;
bent into a series of short curves similar to the scalloped fly edge, and fastened to the
face of the post by screws and clamps, Q.
It is obvious that the scalloped outline will be omitted when it is used for cutting
flies for men's shoes.
In the lower face of the post, between the fly and button-hole knives is a socket in
which is a spring bolt, T, whose operation is similar to that of the pin, and whose
office is to strip the cut flies from the knives as the head is raised.
The material to be cut is placed upon a tapering table, R, Figure 9, the widest
part of which is at the front and which rests on a bed, S, held by a clamp, U.
The general line of the knives is across this table, and it is adapted to be moved
back and forward, transverse to said line so as to place beneath the knives a width
equal to the length of the desired fly.
By this device a fly of a certain length is cut; the material extending beyond the
sides of the table, being unsupported is not cut by the additional knives at either end
of the spring.
To facilitate the adjustment of this tapering table to any desired size the method of
attaching it to the bed and the system of gages shown in Figures 10, 11, and 12 may
be substituted for the simple device just described.
The bed, S', having a plane face at right angles to the motion of the cutting and
marking tools, is attached to the frame of the machine and supports the tapering
table, R, and the gages used with it. The narrow end of the table, R', is pivoted on
a stud, which slides in a slotted iron, r, attached to the bed, S.
Attached to the front of the table, it', is a slotted, segmental, graduated plate, U'
which slides on and is held by a thumb screw, ', which moves in the slotted graduated
plate, V, and may be locked at any point.
The article to be cut or marked is placed on the table, R¹, as indicated by dotted
lines in Figure 10, and its position regulated by gages W and Y.
The gage W, consists of a slotted strip of metal sliding on studs, w, w, connected
with the bed, S; its front end bent to project above and over the table, 1, and con-
nected at its other by a link with a graduated bar, W1, which slides in ways w¹, w¹,
and is locked by a thumb screw w².
The gage, Y, bears at its front end two upwardly projecting pins or equivalent
device which constitutes a rest for one end of the fly.
This gage slides on studs,, y, connected with a movable plate, Z, and is connected
at it outer end by a link with a graduated bar, Y, which slides in ways, y', y', and is
locked by a thumb-screw, 22.
The movable plate, Z, slides freely on the bed. S', and is connected with the pivoted
lever, Z, which rests on a graduated slotted segment, X, and is locked at any point
thereon by the thumb-screw, z.
In operation the marking or cutting tools being adjusted to the desired size, the
table, t, is moved to a position which will present the proper width to said tools;
which position is determined by suitable numbers on the graduated scales Ut and V.
The gages, W, and Y, are similarly located by means of the graduated bars, W¹,
and Y, and segment, X.
By this arrangement, the numbers on each gage, for any desired style, size or
shape, being once ascertained and tabulated, the machine can be, even by an inex-
perienced person rapidly adjusted by reference to the gages only.
In some instances, particularly where curves other than circular are desired, it is
found advantageous to unite the tool-carrying spring at its centre with the head, and
apply the bending device to the ends as shown in Figures 13 and 14.

page_text: The head, A', of the form shown has attached to its front lower face a slotted
post, D', in which the spring, B', is fastened by the screw, d.
But one adjustable post, C, is shown as, from the other drawings, their number and
arrangement will be obvious.
To each end of the spring, B', is hinged a bar, E', the other ends of said bars being
hinged to a nut, G, on the screw, H¹.
The front end of the screw, H, rests against the post, C, where it can be retained
by any suitable device; the other end passing through a bearing, I, terminates in a
thumb-screw, J, by turning which the spring. B', is bent into different curves.
The bearing, 1', holds the screw, H', laterally, and is attached to a nut, 11, by a
vertical pivot.
The nut, I, is mounted on a screw, K', attached to the head, A'.
By this arrangement the screw, K', retains the screw, H', in the central position
shown in Figure 13; or moves it to one side and enables it to bend the spring A' into
curves other than circular.
I do not however confine my invention to the particular device shown for bending
said spring, but any mechanical appliance which will accomplish the same end may be
employed, one form whereof is shown in Figures 15 and 16.
In these last named Figures, in the former of which the head is not shown, D" is
the fixed post and, B", the spring.
Connected with either end of said spring are flexible connections e", e", which may
be of cord, chain or metallic ribbon, their other ends being attached to a pulley, g",
upon a shaft, i, operated by a handle j", by turning which, the band, B", can be
bent to any desired curve.
