Year: 1858

page_text: LETTERS PATENT to Samuel Taylor and David Taylor, of Rochdale, in the
County of Lancaster, Machinists, for the Invention of "IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR PUTTING MACHINE STRAPS OR BELTS ON TO
PULLIES OR DRUMS, AND FOR REMOVING THE SAME."
Sealed the 17th December 1858, and dated the 17th June 1858.
PROVISIONAL SPECIFICATION left by the said Samuel Taylor and David
Taylor at the Office of the Commissioners of Patents, with their Petition,
on the 17th June 1858.
We, SAMUEL TAYLOR and DAVID TAYLOR, of Rochdale, in the County of
Lancaster, Machinists, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PUTTING MACHINE STRAPS
OR BELTS ON TO PULLIES OR DRUMS, AND FOR REMOVING THE SAME," to be as
follows:-
Our Invention consists in the adaptation to pullies or drums of apparatus,
whereby an attendant may put on the strap or band, or remove it without
handling the same, by which means a liability to accident is avoided. For
this purpose we employ a surface adjacent to the drum or pulley, upon which
the strap will rest when off. This surface is caused to rise by a lever or other
apparatus, and when at the proper level, the strap is pushed forward on to the

page_text: pulley by projecting parts which slide laterally. A method we adopt for
effecting these motions consists in the employment of a shaft, capable of being
turned by a lever. On this shaft is the contrivance for carrying the strap
forward. This part of the apparatus is provided with pins that are situate in
inclined slots, whereby it is caused to move sideways, at the same time
drawing the shaft in the like direction; and this motion of the shaft acts
through the agency of an inclined plane, so as simultaneously to raise the
surface which supports the strap.
To the above we add a lever, so arranged as to draw the strap from the
pulley on to the supporting surface above described.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Taylor and David Taylor in the Great Seal Patent
Office on the 17th December 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, SAMUEL
TAYLOR and DAVID TAYLOR, of Rochdale, in the County of Lancaster,
Machinists, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of June, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Samuel Taylor and David Taylor, Her especial licence that we, the said
Samuel Taylor and David Taylor, our executors, administrators, and assigns,
or such others as we, the said Samuel Taylor and David Taylor, our
executors, administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR PUTTING MACHINE STRAPS OR BELTS ON TO PULLIES OR DRUMS, AND FOR
REMOVING THE SAME," upon the condition, amongst others, that we, the said
Samuel Taylor and David Taylor, or one of us, by an instrument in writing
under our hands and seals, or under the hand and seal of one of us,. should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Samuel Taylor, do hereby declare the
nature of our said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, and accompanying Drawing, that is to say :-
Fig. 1 represents the apparatus in vertical section; Fig. 2 is a view taken
at right angles to Fig. 1; and Fig. 3 is a top view in section. a is.a plate
constituting the framework of the apparatus, and which is fixed to a beam or
other convenient part. The surface intended to receive the strap when thrown
off the pulley is shewn at b, its periphery corresponding to a portion of the
circumference of the drum. This surface is mounted upon pins c, which are
situate within inclined slots d, (shewn by dots in Fig. 1), formed in the
stationary framing. An axle e is carried by the plate a, and a bracket f, and
is provided on its outward end with a lever handle g, by which it may therefore
be turned. On this axle is a cam h, designed to act against a rod i, which is
connected at its other end to the surface b, and is governed in its motion by a
guide k, upon the cam therefore being caused to revolve, the rod i will be
thrust forward, and the surface b will be brought into a position level with the
drum. Upon the axle e is fixed a rod l, which passes through a slot m,
formed in the surface b, and is attached at its end to a hoop n, mounted so as
to slide on the said surface, and provided with a flange by which the strap is
carried forward on to the drum. Upon the axle e is also a cylinder p, furnished
with slots q, so as to constitute a grooved cam. Within these slots are pins 1,
attached to the bracket f, so that upon the cylinder p being turned by means
of the handle g, the shaft e is carried inward, and the rod 7 moving therewith,
causes the flange piece n to slide upon the surface, and for the purpose of
steadying this motion, the rod 1 passes through the slot m, the same effect
being also gained by two other guide slots s, s, within which pins fixed to the
flange piece are situate. The action of the apparatus is as follows:-According
to the position shewn in the Drawing, the strap (represented by the red line)
is thrown from the drum, and is resting upon the stationary receiving surface b,
in order to put it on the handle g, is turned, by which means the cam h will,
by thrusting forward the rod i, bring the surface b coincident with the drum t.
During this the grooved camp will also be turned, but the pins will at first
remain within concentric parts of their slots, and the shafte will therefore
simply turn upon its centre without being drawn inward; at the same time
also, the rod will move in a concentric part of the slot m, so as to allow.the
flange piece n to remain in the position shewn, but the level of the drum
having been attained by the surface b, then the camp will bring the inclined
portions of its slots to bear upon the pins r, so as to cause the shaft e to move

page_text: inward, and this carrying with it the arm 7, will slide the flange piece n along
the surface b, and push forward the strap on to the drum t. The strap may
be thrown off the pulley by any ordinary means, but we employ a sliding bar u,
to which a stud v is affixed, when the bar u is therefore caused to slide by
means of a chain w, the strap is carried forward by the said stud on to the
supporting surface. The apparatus is brought back to the position shewn in
the Drawing by turning the handle in the other direction, the supporting
surface being brought back by a chain x attached to it, the other end being
fixed to the cam h, but this chain may be dispensed with when the apparatus
is not applied to a bottom strap. Figs. 4 and 5 represent another arrangement
by which our Invention may be carried into operation. The drum is shewn
at a, and the shaft upon which it is mounted at b. On this shaft is a collar c,
capable of turning loosely and carrying two rods d. On these rods are placed
arms e, so as to slide thereon, and their other ends carry the supporting
surface f, which in this instance is an entire circle. To the arms e are fixed
pins g, which are situated within slots h, which are eccentric to the drum for
a portion of their length, and afterwards concentric. In the cylinder con-
stituting the supporting surface is an inclined slot i, within which is a pin k,
attached to the sliding flange piece 7, the said flange is also furnished with a
pin m, projecting through the framework n. Supposing the strap to be
thrown off, and resting upon the surface f, a handle o, attached to the collar c,
is turned, by this means the pins 9 will be caused to move in the eccentric
parts of the slots h, so as to move the arms è upon the rods d, and bring the
cylinder concentric with the drum. During this movement the cylinder
will also be carried round, and with it the flange piece 1, but the coincidence
of the circumferences having been gained, the pin m will arrive in contact
with a stop p, and the flange piece being no longer capable of revolving, will
be forced forward by the slot i, so as to put on the strap, during which move-
ment the pins g will move in the concentric portions of their slots.
Having thus described and ascertained the nature of our said Invention,
and the manner in which the same is to be performed, we desire it to be
understood that although we have shewn and described certain methods
of carrying our Invention into effect, yet we do not confine ourselves
thereto, as many well known mechanical agents may be employed as
equivalents, and it will be evident that the position of the supporting sur-
face will be regulated by the direction in which the strap runs. In Fig. 1
it is supposed to run horizontally as indicated by the red line, but by
turning the drawing so that the top thereof shall be at A, the apparatus is
adapted for a vertical strap. We would also remark that there are two

page_text: operations in our Invention, the one consisting in bringing the supporting
surface coincident with the drum, and the other in pushing the strap thereon.
The former of these may, if desired, be used separately, in which case the
strap may be put on by any ordinary means, and when off it will be supported
without consuming power, as in the case of loose drums or pullies, and
without the risk of accident arising from putting on by hand. That which we
claim as secured to us under the above in part recited Letters Patent is,
the use of a supporting surface for receiving the strap capable of being
removed from and brought into coincidence with the periphery of the drum,
and also the sliding apparatus described therewith for pushing forward the
strap.
In witness whereof, I, the said Samuel Taylor, have hereunto set my
hand and seal, this Sixteenth day of December, in the year of our
Lord One thousand eight hundred and fifty-eight.
SAMUEL TAYLOR. (L.S.)
