MACHINES"
COMPLETE SPECIFICATION filed by the said Charles Henry Trask at the
Office of the Commissioners of Patents on the 13th June 1881.
CHARLES HENRY TRASK, of the City of Lynn and State of Massachusetts, in
the United States of America. "IMPROVEMENTS IN BOOT AND SHOE SOLE EDGE
SETTING AND BURNISHING MACHINES,"
This Invention relates to improvements in boot and shoo sole edge setting
machines, wherein a reciprocating burnisher is employed to set and burnish the
edges of the soles of, boots and shoes.
In carrying out this Invention I construct a horizontal tilting frame, having an
adjustable counterbalance, and provided with suitable belt pulleys, which are
journalled in hangers secured to the ceiling over head, and I provide one end of
said frame with smaller belt pulleys, which are journalled within a horizontal
yoke-frame connected thereto by means of a swivel-joint, and 1 suspend from the
journals of said belt pulleys a yoke-frame, to which is connected a vertical tube,
the lower end of which is provided with a ball-and-socket-joint having a belt
pulley and eccentric journalled within the ball at or near the axial line thereof.
Extending downward from said ball is a hollow operating handle having enclosed
a centrally pivoted bar, the upper end being connected with the eccentric and the
lower end provided with one or more burnishers, which may be supplied with heat
from a suitable gas-jet or burner. Power and motion being communicated to the
burnisher, it is guided by hand over the edge of the sole of a boot or shoe; the
ball-and-socket-joint thus arranged permits the free movement of the suspended
reciprocating burnisher over the various curves and angles of the edge of the sole
of a boot or shoe held in a suitable jack so as to set and burnish the same with
great rapidity and in a very superior manner.
But in order that my Invention may be fully understood I will proceed to
describe the same in detail by the aid of the accompanying Drawing, in which
Figure 1 represents a side elevation of a burnishing machine constructed
according to my Invention.
Figure 2 represents a top view of the same.

page_text: Figure 3 represents an end elevation of automatic shipping mechanism for
controling the action of the burnisher.
Figure 4 represents in elevation the ball-and-socket-joint with the burnishing
devices connected therewith.
Figure 5 represents a vertical section of the ball-and-socket-joint and handlo
and an elevation of the reciprocating-bar and burnishers.
Figure 6 represents a vertical section of the same taken at a right angle to the
former.
A represents a belt pulley journalled in the hangers B, which are secured to the
ceiling or beams over head and support the horizontal tilting frame C, one end of
which is provided with an extension bar D, upon which is secured the adjustable
counterbalance or weight E, the opposite end of said frame being provided with a
socket F, into which is fitted the end of the yoke-frame G, and secured by a pin,
which operates in an oblong hole so as to permit said yoke-frame G to swivel
therein. Within said yoke frame G is journalled the belt pulley H, and to the
journals thereof is suspended the yoke-frame I, which sustains the vertical pendant
tube J, to the lower end of which is secured the skeleton socket K, which partially
encloses the ball L, within which is journalled the grooved belt pulley M secured
upon its journal, which is provided with an eccentric N, which fits within the
bifurcated upper end of the reciprocating bar P, which bar is pivoted at or near
its central portion within the hollow operating handle O, and its lower end provided
with one or more burnishers R secured thereto by screw bolts and thumb nuts S,
and adapted to be heated by gas from the burner T pivoted beneath the shield U,
so as to operate as a stop-cock whon turned horizontally to shut off the gas which
passes downward through said pendent tubo J, and is conducted around tho said
ball-and-socket-joint K, L, by the flexible gas tube Q and thence through the
hollow handle O to the said burner T.
Motion being given to the pulley A, it is communicated to the pulley H by the
belt V and thence by the vertical belt W to the grooved pulley M, thereby rotating
the eccentric N, which actuates the vertical bar P, through which a very rapid
reciprocating movement is imparted to the burnisher R.
Now in order that the reciprocating movement of the burnisher may be regulated
or adjusted according to the nature of the work being burnished, the said
reciprocating-bar is provided with an adjustable or variable pivotal bearing,
consisting of a screw bolt a, which may be inserted through either one of several
holes c formed in the handle and reciprocating bar to correspond, thereby permitting
a longer or shorter movement to be imparted to the burnisher, as may be
desired.
The shaft b, upon which the pulley A. is secured, is extended beyond the hangers,
and has fastened upon it near its end a friction disc f, and is provided with a loose
pulley d, having a friction face plate e, and is driven by the belt Y, and may be
slid longitudinally upon said shaft b by the interposition of the bevel edged
clutch-wheel g acting between the beveled ond of the pulley hub and the beveled
end of the collar h secured upon the said shaft b so as to cause said pulley face
plate e to make contact with the said friction disc f, and thereby rotate the shaft b
and thus actuate the burnisher. This clutch-wheel g is journalled within the
frame suspended from the horizontal bent lover arm i, which is pivoted to the
hanger n, its opposite end being pivoted to the vertical rod k, adjustably attached
to the tilting framo C, so that when the same is at or about in a horizontal
position the said mechanism is brought into position so as to operate the
burnisher.
Now, if the burnisher and pendant mechanism is raised upward sufficiently the
frame C is thereby tilted so as to disengage the friction clutch-wheel and permit
the friction pulley d to be revolved upon said shaft b and thereby arrest the
movements of the burnisher.
I contemplate arranging and connecting the above described mechanism with the
tilting frame C at the opposite side of its journal or pivotal bearings in said

page_text: hanger, so that an excessive movement of the end of said tilting frame in the
opposite direction or downward will serve the same purpose of arresting the
movements of the burnisher, as before described.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I claim,—
1. The reciprocating bar, having an adjustable pivotal bearing, and adapted to
receive horizontal movement at its upper end from an eccentric, and having its
lower end provided with means for attaching a burnishing device, substantially as
described.
2. The reciprocating bar, pivoted at or near its central portion, and having its
upper end bifurcated and adapted to receive therein an eccentric, and having its
lower end provided with clamping devices adapted to secure thereto one or more
burnishers, substantially as and for the purposes set forth.
3. The combination with the ball-and-socket-joint, having a belt pulley and
eccentric journalled at or near the axial line thereof, of the reciprocating bar
pivoted at or near its central portion, and provided with one or more burnishers,
substantially as described and for the purposes specified.
4. The ball-and-socket-joint, having a belt pulley journalled within the ball at
or near the axial line thereof, substantially as described and for the purposes set
