PROVISIONAL SPECIFICATION left by the said Samuel Allmark, John Hayes,
and Joseph Allmark, at the Office of the Commissioners of Patents on the 28th
November 1879.
SAMUEL ALLMARK and JOHN HAYES, both of Oldham, and JOSEPH ALLMARK, of
Middleton, all in the County of Lancaster. "IMPROVEMENTS IN THE CONSTRUCTION
OF TRAM-CARRIAGES FOR MILLS, WORKSHOPS, AND OTHER PLACES, PART OF WHICH
IS APPLICABLE TO THE CONSTRUCTION OF RACKS FOR STORING ROLLERS, DRILLS,
RIMERS, GUNS, AND OTHER ARTICLES."
Our improvement consists principally in so constructing and arranging tram-
carriages that each article to be carried (such as rollers, cans, or other portions of
machinery) has its own separate carriage, and that any number of these carriages
may be readily joined together to form a train, two being the minimum.
The connections are so arranged that the carriages will pass round a curve of
twelve inches radius, or run in a serpentine or zigzag form, as well as in a straight
line.
For this purpose each carriage is provided with he and she joints, or half taps,
both at top and bottom, with a vertical pin passing through the centre of both,
thus holding them firmly together, yet allowing them to swivel when the line is
curved.
This pin is made of sufficient length above to support the top rail of the
carriage, which receives the upper end of the roller or other article.
The top rail is similar in construction, to the lower part of the carriage so far
as the joints are concerned, so that it works on the top of the before mentioned

page_text: pins in unison with the carriage. We use a rod supported by the wall or upon
pillars for guiding the top of the carriage similar to those now in use.
The lower part of the carriage is constructed with two jaws or an open bearing
to receive a wheel or sheave in the ordinary manner, which allows for any
unevenness of the rails upon which the wheels run.
The carriage is also provided with recessed cups to receive the lower end of the
rollers, or other articles to be carried similar to those now in use.
The top rail is provided with recesses or notches to receive the upper end of the
roller or other article, a catch lever being attached working on a stud in such a
manner as to swivel clear of the recess whilst the roller or other article is being put
into position, and so weighted that when released it will fall down by its own
weight across the recess or notch, and thus effectually secure the roller or other
article in an upright position.
This latter arrangement is suitable also for existing tram carriages, and for
stationary racks for storing rollers, drills, rimers, gnns, or other articles requiring
to be held in any given position.
The method of coupling the carriages together may also be adapted to flat topped
trucks for carrying skips or other like articles.

by the said Samuel Allmark, John Hayes, and Joseph Allmark in the Great
Seal Patent Office on the 28th May 1880.
SAMUEL ALLMARK and JOHN HAYES, both of Oldham, and JOSEPH ALLMARK, of
Middleton, all in the County of Lancaster. "IMPROVEMENTS IN THE CONSTRUCTION
OF TRAM CARRIAGES FOR MILLS, WORKSHOPS, AND OTHER PLACES, PART OF WHICH
IS APPLICABLE TO THE CONSTRUCTION OF RACKS FOR STORING ROLLERS, DRILLS,
RIMERS, AND OTHER ARTICLES."
Our improvement. consists principally in so constructing and arranging such
tram carriages that each article to be carried (such as rollers, cans, or other portions
of machinery) has its own separate carriage, and that any number of these carriages
may be readily joined together to form a train, two being the minimum. The
connections are so arranged that the carriages will pass round a curve of twelve
inches radius, or run in a serpentine or zig zag form, as well as in a straight line.
Such being the nature and object of my said Invention, I will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect, and in order that the same may be clearly understood
I have annexed hereunto a Sheet of Drawings illustrative thereof, and have
inarked the same with figures and letters of reference corresponding with those in
the following explanation thereof.
Fig. 1 in the annexed Drawing is a side elevation, and Fig. 2 a sectional view
showing a train of our tram carriages.
To enable the train to pass round corners or to run in a serpentine form each
carriage a, a, is provided with he and she joints, or half laps, both at the top and
bottom, with a vertical pin b, b, passing through the centre of both, thus holding
them firmly together, yet allowing them to swivel when the line is curved.
This pin b, b, is made of sufficient length above to support the top ruil c, c, of
the carriage, which receives the upper end of the roller or other article.
The top rail c, c, (see plan view, Fig. 3), is similar in construction to the lower
part a, a, of the carriage (see plan view, Fig. 4) so far as the joints are concerned,
so that it works on the top of the before mentioned pins b, b, in unison with the
carriage. We use a rod d, d, supported by the wall or upon pillars for guiding the
top c, c, of the carriage similar to those now in use, except that the bracket ď³, ď¹,
carrying the bowls k, k, swivels on the rod d, d.
The lower part a, a, of the carriage is constructed with two jaws e, e, or an
open bearing to receive a wheel or sheave f, f, in the ordinary manner, which
allows for any unevenness of the rails upon which the wheels run.
The
The carriage a, a, is also provided with recessed cups g, g, to receive the lower
end of the rollers or other articles to be carried similar to those now in use.
top rail is provided with recesses or notches to receive the upper end of the roller
or other article, a catch lever h, h, being attached working on a stud in such a
manner as to swivel clear of the recess whilst the roller or other article is being
put into position, and so weighted that when released it will fall down by its own
weight across the recess or notch, and thus effectually secure the roller or other
article in an upright position.
This latter arrangement is suitable also for existing train carriages, as shown at
Fig. 5, in elevation and plan view, and for stationary racks for storing rollers,
drills, rimers, guns, or other articles requiring to be held in any given position.
In some cases we make the notches extend through the rail (instead of being at
one side only) as shown at i, i, so that the roller or other article can be removed
from either side, in which case two catch levers h, h¹ will be required.

page_text: The method of coupling the carriages together may also be adapted to flat
topped trucks for carrying rollers, skips, or other like articles (see plan view,
Fig. 6).
Having now described the nature and object of our said Invention, together with
the manner in which the same is to be or may be performed or carried into
practical effect, we wish it to be understood that we claim as our Invention the
construction of tram carriages and racks for mills, workshops, and other places,
substantially in the manner above described and illustrated by the Drawings
annexed, and for the purposes hereinbefore set forth.
In witness whereof, J, the said Joseph Allmark (on behalf of myself and the
said Samuel Allmark and John Hayes) have hereunto set my hand and
seal, this Twenty seventh day of May, in the year of our Lord One thousand
eight hundred and eighty.
JOSEPH ALLMARK. (L.S.)
