PROVISIONAL SPECIFICATION.
Improved Devices and Means in the Manufacturing of Machine Belts
and Bands to Strengthen and Prevent them Stretching.
I JOHN ISRAEL HEMMINGWAY of Dixon Street Sheffield in the County of
York Engineer do hereby declare the nature of this invention to be as follows
--
By improved devices applied in the making of belts and bands whereby the
same are strengthened and the stretching thereof prevented. This is accomplished
in the following manner. Upon an ordinary flat belt or band which may be made
of leather hemp canvas or any suitable composition or compound place a
shielding or plating of iron steel brass or other suitable metal which is secured
upon the outside of the belt or band and by means of devices (some of which are
described and illustrated in the Patent Specification No. 5890 and dated
20th March 1893). The shielding or plating is so arranged that when it is by
means of the prongs or shanks formed thereon secured to the belts or bands it
strengthens and prevents them stretching. In applying this invention to the
making of link or chain belting a link made of leather papier-maché pulp or any
composition may be used as a foundation for the belt. The link may be of any
desired shape length depth or thickness and may have one two or more holes
therein. Plates or shields are secured to each side of the link by improved
devices similar to those shewn in Patent Specification No. 5890 dated 20th March
1893. The plates or shields are so arranged that only the pliable link comes in
contact with the face of the pulleys the plates being less than the pliable link
thus retaining the gripping power of the belting on the pulleys and with the rivets
or pins passing through all these links and the plates or shields thereon, greater
strength is given and the pliable links are prevented from stretching.
Dated this 4th day of April 1894.

Improved Devices and Means in the Manufacturing of Machine Belts
and Bands to Strengthen and Prevent them Stretching.
I, JOHN ISRAEL HEMMINGWAY of Dixon Street, Sheffield, in the County of
York 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 :-
This invention relates to improved devices, to be applied in the making or
construction of machine belts or bands, for the purpose of both strengthening, and
To attain this result I

form the belt or band (which may be of leather, hemp, canvas or paper, or a
combination of any of the said materials, or any other suitable composition or
compound) having on the outer side of the same, a covering, in whole or part, as
may be found most advantageous, of iron, steel, or any other approved metal,
secured to the belt, by means of devices (some of which are described and illustrated
in the Patent Specification No. 5890 and dated March 20th 1893.
By referring to the accompanying sheet of drawings, in the various figures of

page_text: which same or similar letters indicate same or similar parts or details, it will be
seen how I preferably adopt my improved devices to belts of different construction
and design, although I do not confine or bind myself to the arrangements shewn,
but which will be found sufficiently explanatory to illustrate the principle of my
invention.
Figures 1 and 2 shew an edge view and plan respectively of a belt or band
having an outer covering A. of steel, iron or other suitable metal, in segments or
parts, and which are securely joined together by pins B, or their equivalent, the
joints B', are preferably made like a hinge, and the outer edges A' of the metallic
sheathing A may be turned over, and made to engage with the lining C of said
belt, which may be of leather, hemp, canvas, paper mache, in pulp or otherwise, or
any other composition er material which may be deemed advisable.
The hinged portion B', allowing perfect freedom, and ensuring pliability, great
strength, together with additional gripping power is thereby gained.
Figures 3 and 4 illustrate an edge view and plan respectively of a belt or band
formed or composed of any desired number of separate and detachable links D,
made of leather, hemp canvas, or any other suitable material, or combination of the
same the said links being strengthened and protected by metallic plates D', through
which suitable holes E are punched or formed in such a manner that the displaced
portion E' bends inwardly, at right angles to the said plate, forming a continuous
metallic bearing, through the whole or part of the links D, against which the
connecting pins B may freely work.
It will be seen that the part or portion of the belt or band, composed of leather
hemp, canvas, or other suitable material or combination of materials C, which
comes in contact with the face of pulleys or drums, is larger than and projects
beyond the before described metallic side links D', by this means the gripping
and adhesive power of the belt is retained, while obtaining additional strength
and pliability, with entire immunity from stretching.
Figures 5 and 6 shew the metallic link detached and separate.
Figures 7 and 8 shew a modified form of metallic side link in which an elongated
hole E may be punched or formed the projecting points E', before described being
dispensed with. In lieu of the same I bend a flat piece of suitable material F (of
width equal to that of the compound link) to a similar configuration to that
illustrated, by this means also forming a continuous metallic bearing for the pins
or rivets.
Figures 9 and 10 shew a detachable metallic shield G which I adopt for the
purpose of strengthening and preventing any stretching of an ordinary flat belt or
band and which is shewn in position on Figures 11 and 12. The shields G may
be secured in position by prongs or projecting portions H, similar means or devices
for which are shewn in Patent Specification No. 5890 March 20 1893, and
previously mentioned herein. The shape or configuration of the shields may be
varied as circumstances demand.
Figures 13 and 14 illustrate a modification of the arrangement or method shewn
by Figures 1 and 2, but in which the hinged portion is made to butt up against,
instead of engaging with each other. This necessitates the joints B', being made by
the links or bent pins J as shewn in position and separate by Figure 21.
Figures 15 and 16 shews a further modified form of metallic covering, and in
which the hinged joints of the metallic sheathing are carried lengthways in addition
to across the belt, suitable for belts running over convex pulleys.
Figures 17 and 18 shew how the strengthening shields D¹, may be in part, turned
up K, and when in position on belt C, as shewn by Figures 19 and 20, constitute or
form an elevator or conveyor.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1st. In the making of belts or bands (composed of leather, hemp, canvas, paper

page_text: mache, or other suitable material or compound) the use of metallic plates to
strengthen and prevent them stretching, by the devices and means, as hereinbefore
described and illustrated on drawing.
2nd. In the manufacture of belts or bands (consisting of separate and detachable
links, which may be composed of leather, hemp, canvas, paper-mache or any com-
bination of materials) the use of metallic links and pins having a continuous metallic
bearing for the pins to bed upon, substantially as and for the purpose or purposes
hereinbefore described and illustrated.
3rd. The use and manufacture of the metallic shields, for the purpose of
strengthening and preventing the stretching of the ordinary belts or bands,
substantially as and for the purpose or purposes hereinbefore described and
illustrated.
Dated this Second day of January 1895.
