COMPLETE SPECIFICATION.
Improvements in Machines for Covering Rolls with Leather.
I, JAMES SWIFT TURNER, residing upon Gay Street, North Chelmsford, Middlesex
County, Massachusetts, United States of America, Manager, 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 machines for applying leather coverings to rolls such as
those used in spinning-machines. The invention consists in the novel features of
construction and arrangement which I shall now proceed to describe and claim.
Of the accompanying drawings, forming a part of this specification :-
1
Figure represents a side elevation of a machine constructed in accordance with
my invention.
Figure 2 represents a detail end view of the acting portion of one of the
stretching-arms.
Figure 3 represents a section on line 3-3 of Figure 2.
Figure 4 represents a view of the under face of the parts shown in Figures 2
and 3.
The same reference characters indicate the same parts in all the figures.
The purpose of the machine is to stretch a leather band over the periphery of a
wooden or metal roll, the band being naturally shorter than the length of said
periphery; and to this end are employed a pair of oppositely disposed claws or arms
having provisions for engaging the ends of the leather band, and means for moving
said arms to draw the ends of the band together.
Referring to the drawings, I have represented a base a, upon which are mounted
two standards b b joined at their upper ends by a brace c and journalling a shaft d
on which are mounted two worm-gears e e having respectively right and left hand
threads. Between ears b¹ 61 on the two standards bare pivoted two levers fƒ formed
at their upper ends with worm-gear segments f¹¹, which mesh with the worms e e.
At the lower ends of said levers are pivoted the two stretching-arms or claws g g.
In the middle of the base are mounted standards supported on a slide h¹ which is
arranged to move transversely of the base. Through the center of said standards
extend posts i, having screw-threaded stems engaged by adjusting-nuts which may
be turned to raise and lower the posts. The posts i carry recessed blocks i¹ at their
upper ends, adapted to support the trunnions of a roll k which it is desired to
cover with leather.
The operating ends of the arms are provided with removable end-pieces g'
secured to the arms by screws 72, and thickly studded with pins g³ g³ having pointed
lower ends. When the arms are moved to stretch the leather band over the roll, the
pins g³ become embedded in and firmly engaged with said band.
The machine is operated by first placing the roll k in its supports, as shown in
Figure 1. The leather band m which is to form the peripheral covering of the
roll is then placed around the roll, its inner surface, or the surface of the roll,
having preferably been first coated with cement or glue, and the ends of the
arms g are brought into contact with the leather near its ends. Then by rotating
he shaft d in such a direction as to cause the arms to move toward each other,

page_text: the pins g3 become embedded in the leather, and a continued rotation of the
shaft causes the ends of the band to be brought together. The leather may then, if
desired, be secured to the roll by means in addition to the cement or glue, while
the stretching-arms are still engaged with its ends, and said arms then retracted
by a reverse movement of the shaft d. When a wooden roll is being covered, the
ends of the band may be tacked to the wood.
ccare two hooks suspended from the brace or cross-bar c, and designed to
support the ends of the arms g g when the latter are not in use.
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 is-
In a machine of the character described, a pair of oppositely disposed
stretching-arms, and end-pieces formed to fit said arms and removably secured
to the ends thereof, the said end-pieces being thickly studded on their acting
faces with pins which have pointed ends adapted to become embedded in the
ends of a leather band for the purpose of stretching the same over a roll.
