Complete Specification Left, 4th May, 1899-Accepted, 10th June, 1899
We, CHARLES DAWSON, of No. 230, St. Joseph Street, of the Town of Lachine, in
the County of Jacques Cartier, Province of Quebec, Dominion of Canada, Machinist,
and ELI ADLER, of 39, Dominion Avenue, in said Town of Lachine, Superintendent,
do hereby declare the nature of this invention to be as follows:-
This invention has for its object to provide means for shipping a belt, as, for
instance, from a loose to a tight pulley, or vice versa, that will be neither liable to
become heated itself, nor to cause the belt being shipped to become heated, owing to
the friction between it and the shipper, besides providing an exceedingly durable,
and therefore inexpensive article.
The invention may be said, briefly, to consist of a forked bracket adjustably secured
to the shipper rod, the prongs whereof are adjustable toward and away from one
another, in order to accommodate various widths of belts, said prongs preferably con-
sisting of a rigid core or trunnion upon which a sleeve is rotatably mounted in a
novel and advantageous manner.
More specifically speaking, the shipper, which rod may be of any approved con-
struction, but preferably round, receives an oblong block transversely perforated, to
take over it, and held in place by a set screw, and provided with a transverse opening
at right angles to the perforation.
This opening receives the shank of the shipper bracket, which is also held against
displacement by a set screw, and is formed with a flat cross bar, having slots
adapted to receive the diminished screw-threaded inner end of the rigid cores or
trunnion.
The inner end of each of these cores or trunnions is diminished to form a concave
shoulder or rigid collar, while the main portion is tapered, and the end thereof
longitudinally grooved, and screw-threaded to receive a nut having a concave edge,
and a jam nut, between which latter and the first mentioned nut, a flexible washer
having a spline is located, the spline taking into the groove in the trunnion.
A rotatable sleeve takes over each of these cores, and has its outer ends flared, to
form concavities adapted to, in conjunction with the concave collar and concave nut,
form run-ways for two series of balls, the outer end of the sleeve being extended
sufficiently in length to overlap the end of the core or trunnion, and be closed,
against dust &c., by a cap.

We, CHARLES DAWSON, of No. 230, St. Joseph Street, of the Town of Lachine, in the
County of Jacques Cartier, Province of Quebec, Dominion of Canada, Machinist, and
ELI ADLER, of 39, Dominion Avenue, in said Town of Lachine, Superintendent, 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:-
The invention has for its object to provide means for shipping a belt,-as, for
instance, from a loose to a tight pulley, or vice versa,-that will be neither liable to
become heated itself, nor.to cause the belt being shipped to become heated, owing to
the friction between it and the shipper, besides providing an exceedingly durable, and,
therefore, inexpensive article.
The invention may be said, briefly, to consist of a forked bracket, having a single
arm adjustably secured to the shipper-rod, the. prongs whereof are adjustable toward
and away from one another, in order to accommodate various widths of belts,―said
prongs preferably consisting of a rigid core or trunnion, upon which a sleeve is
rotatably mounted in a novel and advantageous manner, for full comprehension
whereof, and of our invention, in its entirety, reference must be had to the ac-
companying drawings, forming a part of this specification, in which like symbols
indicate the same parts, and wherein :-
Figure 1 is a plan view of our improved shipper, illustrating one of the prongs
thereof in longitudinal section; Fig. 2, a side elevation thereof; Fig. 3, a plan view
of the uut-locking washer; Fig. 4, a plan view of the split bushing, for retaining the
balls at the outer end of the prong against displacement; and Fig. 5, a transverse
sectional view, taken on line 5--5, Fig. 1.
The shipper-rod 5 may be of any approved construction, but is preferably round.
It receives an oblong block 6, which is transversely pierced, as at 7, to take over the
rod 5, wherein it is held in place by a set-screw 6*. The block 6 is also provided
with a transverse opening 8, at right angles to the hole 7. This opening 8 receives
the shank, 9, of the shipper-bracket, which is adjustably fixed therein at the desired
length by a set screw 9. 10 is a flat crose-bar formed on the shank 9, and having
slots, 11, adapted to receive the diminished screw-threaded inner end 12 of the rigid
cores or trunnions 13, the inner end of each of which is diminished to form a concave
shoulder or rigid collar 14, while the main portion is tapered, and the end thereof
longitudinally grooved, as at 15, and screw-threaded to receive a nut 16, having a
concave edge 17 and a jam-nut 18, between which and the nut 16 is a flexible
washer 19, having a spline 20, the spline taking into the groove 15 in the
trunnion 13.
21 is a rotatable sleeve, which has its inner and outer ends flared, as at 22 and 23,
respectively, to form concavities, as shown adapted in conjunction with the concave
shoulder 14 and the nut 16, to form run-ways for two series of balls 24 and 25
respectively, the end 23 being extended sufficiently in length to overlap the end of
the core or trunnion, and be closed against dust, &c., by a cap 26.
In assembling the parts of this improved shipper, the sleeves 21 are first slipped
over the core or trunnions.
They are then turned, with end 22 of the sleeve uppermost, the series 24 of balls
dropped in place, and the sleeve slipped to its normal position. The trunnion and
sleeve are then reversed and set with the tapered end of the core or trunnion
uppermost.
A split bushing 30 is then sprung over said tapered end, and forced along it, until
its outer face is approximately on a line with the inner edge of the concavity at 23.

page_text: The series of balls 25 are then dropped into place, and the nut 16 screwed upon the
end of the trunnion, until it comes into contact with the bushing 30, thus retaining
and establishing a run-way for said series of balls 25, the washer 19 being then placed
next to said nut 16, and the jam-nut screwed in place tightly against said washer,
after which the cap 26 is secured in place.
It is evident that a shipper constructed according to this invention obviates the
great defect in belt-shippers heretofore used, in that there will be practically no
friction between it and the belt, and therefore neither will become heated during the
shipping of the belt, thus allowing the use of belts manufactured of rubber
fibre and other material, that could not heretofore be used if shipping were
necessary.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
for
1. A belt-shipper having a shipper-rod, a forked bracket having a single arm
adjustably secured to said shipper-rod transversely thereof, and means
adjusting said bracket transversely of said shipper-rod, substantially as set forth.
2. A belt-shipper having a shipper-rod, a forked bracket adjustably secured to said
shipper-rod transversely thereof, means for adjusting said bracket transversely, and
means for adjusting said bracket longitudinally of said shipper-rod, substantially as
set forth.
3. A belt-shipper having a shipper-rod, a forked bracket having a single arm
adjustably secured to said shipper-rod, transversely thereof, the prongs of said bracket
being adjustable toward and away from one another, means for adjusting said prongs,
means for adjusting said bracket transversely, and means for adjusting said bracket
longitudinally of said shipper-rod, substantially as set forth.
4. A belt-shipper having a shipper-rod, a forked bracket secured to said rod, and
consisting of a shank and a cross-piece formed integrally with one another, and a pair

substantially as set forth.
5. In a belt-shipper, a pair of prongs, each consisting of a core or trunnion, and an
elongated sleeve rotatably mounted thereon, with means for retaining said sleeve in
place, substantially as set forth.
6. A belt-shipper having a shipper-rod, a forked bracket secured to said rod, and
consisting of a shank and a cross-piece formed integrally with one another, and a pair
of prongs mounted upon said cross piece, and projecting laterally therefrom, said
prongs each consisting of a core or trunnion formed near one end with a rigid collar
having a concave face, the ends being screw threaded, and the end adjacent to said
collar taking through a slot in said cross-piece, a nut to secure said core or trunnion
in place, a nut having a concave edge adapted to take over the other end, means for
retaining said latter nut against displacement, a sleeve adapted to take over said
core or trunnion, and having its ends flared to provide concavities to register with
said concave collar and concave nut, and form run-ways for series of balls, .and a
series of balls in each of said runways, substantially as described and for the purpose
set forth.
