be Used for Driving Belts or other Purposes.
I, SAM HALEY of the firm of Thomas Haley and Company of Bramley, near
Leeds, Yorkshire Machine Makers do hereby declare the nature of this invention to
be as follows:-
-
This invention has reference to prior Letters Patent granted to me bearing date
the 7th day of September A.D. 1883 No. 4301.
My present invention consists in means to be employed for placing pressure upon
the leather passing over the cutting gauge or roller, and in means for keeping the
pressure equal during the process of splicing.
In carrying out my present invention I make use of the hinged inclined table
carrying the cutting gauge or rollers as set forth in my prior patent above referred
to, but instead of having a roller on the top of the leather as previously I make use
of a series of spring blades (or one long blade) carried by a hinged cross bar or rail,
such spring blades being so arranged that their extreme points press upon that part
of the leather which is being spliced.
When commencing to splice, the leather is placed over the cutting gauge or roller
and under the spring blades, the pressure thereon for cutting being adjusted by the
inclined table, and in order to keep the pressure equal throughout the whole length
of the splice the cutting gauge or roller which is carried by the inclined table comes
into contact with an adjustable screw projecting from the hinged cross bar carrying
the spring blades, so that as the splice is being made the cutting gauge or roller
follows up to the spring blades which are allowed to rise by the oscillating of the
hinged cross bar which equalizes the pressure throughout the whole length of splice.
India rubber or other cushions are employed to soften the pressure.

be Used for Driving Belts or other Purposes.
I, SAM HALEY, of the firm of Thomas Haley and Company, of Bramley, near
Leeds, Yorkshire, Machine Makers, do hereby declare the nature of my invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SPLICING LEATHER TO BE USED
FOR DRIVING BELTS OR OTHER PURPOSES," 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 reference to prior Letters Patent granted to me bearing date
the 7th day of September 1883, No. 4301.
My present invention consists in means to be employed for placing pressure
upon the leather passing over the cutting or gauge roller, and in means for keeping
the pressure equal during the process of splicing.
In order that my invention may be better understood I herein give reference to the
accompanying sheet of drawings, wherein Fig. 1 is end view of a leather splicing
machine having my improvements applied thereto. Fig. 2 is plan view of same, and
Fig. 3 is section taken through the line A, B, in Fig. 2. Cis framing of machine,
D the reciprocatory cutting knife, receiving its motion by eccentric from the main driving
pulleys E, all arranged in the ordinary manner. F is a carriage caused to travel
backward and forward by means of rack G and pinion H, operated when required by
gearing I and "swaife
or handle J. The hinged inclined table referred to in my
previous specification No. 4301 of 1883 is shewn at K, and is hinged at a to
bracket b, projecting from the carriage F, the front edge of which inclined table bears
upon the wedges forming part of racks M, also secured to the carriage F, such said
racks being in gear with pinion wheel N, fixed onto the cross shaft c, carrying
toothed wheel O, held in position, and prevented from rotating when required by
catch d, all of which are supported by brackets e, carried by the said carriage F.
The cutting roller P and bottom roller P₁, are carried at each end by blocks or
pedestals f, and are caused to rotate in the proper direction on the movement of the
carriage F by pinion g, working in the rack h, fixed at one end of the inclined
table K. A piece of leather under operation for splicing is shewn at Q, and in
order to place and to maintain equal pressure upon the said leather during the whole
of the cutting operation, I employ one blade or a series of steel spring blades m,
attached by set screws n to the cross bar or rail R, capable of rocking or oscillating
upon studs p, working in pedestals r, attached to the main framework."
The hinged cross bar R carries two adjustable set screws s, the points of which
rest upon the top of the blocks or brackets f, so that the said blocks are caused to
rise as hereinafter explained, and the cross bar R made to rock or oscillate upon
the studs p in such manner as to equalize the pressure of the blades m upon the
leather throughout the whole length of splicing when cutting the taper. The amount
of elasticity or spring which the blades m are allowed to have is regulated by set
screws t.

page_text: The modus operandi is as follows :-
When commencing to splice a piece of leather it is passed between the nipping
rollers S, and placed with its front edge against the adjustable stop piece or gauge u,
the rollers S which are eccentric upon their shaft, are operated by handle T so as to
nip the leather tightly between the said rollers, and prevent slipping. The rack M
and pinion N are operated by moving wheel O with the hand of the operator, so as
to place the wedge L under the inclined table K in such manner, that the cutting
rollers P are caused to rise and bear with sufficient pressure under the leather, at
the same time the flat springs m force the leather upon the top of the roller, so that
the grip upon the leather is sufficient for the cutting operation.
The carriage F is also placed inward as shewn in section Fig. 4, and all the parts
are ready for a cutting operation, which is effected by the movement of the handle J,
causing the carriage and all the parts carried thereby, to move in the direction of the
arrow.
The outward movement of the carriage will pull the leather against the knife, and a
splice will be made at such an angle as will correspond to the angle of the table K,
and as the rear end of the table is higher than the forward end which rests upon the
wedge; it follows that the cutting rollers P, and their pedestals would be propor-
tionately raised during their forward movement, in doing which the said pedestals
which are acting against the adjustable set screws, would also be raised, consequently
the cross bar R would oscillate to exactly the same extent, so that the pressure of the
steel blades m upon the leather remains the same throughout the cutting operation.
When the splice is completed the handle is reversed, the leather removed, and the
carriage wound back for another operation, and so on, one time after another.
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 as my
invention is:-
The hinged cross bar R carrying one or more flat spring blades m in combination
with the hinged table K, all operated in the manner and for purposes substantially as
set forth.
