PROVISIONAL SPECIFICATION.
Improvements in Rollers, Wheels, Pulleys, and like articles.
I MAURICE LACHMAN of St. George's Club, Hanover Square in the County of
Middlesex, Gentleman, do hereby declare the nature of this invention to be as
follows:-
My invention relates principally to the construction of rollers or wheels for small
articles such as for furniture castors but it is applicable also to pulleys and articles
of a like nature.
In making such articles and carrying out my invention I propose to form same in
parts or halves which are stamped or pressed from sheets or discs of metal, suitable
shoulders or Hanges being formed to strengthen the parts when joined together by
soldering brazing or in other suitable ways.
To strengthen the article and to provide an increased bearing surface on the
spindle or shaft, flanges or turned in edges are provided about the central opening
through which the spindle or shaft is inserted.
The stamping is preferably effected by suitably shaped dies or plungers.

COMPLETE SPECIFICATION.
Improvements in Rollers, Wheels, Pulleys, and like articles.
I, MAURICE LACHMAN of St. George's Club, Hanover Square, in the County
of Middlesex, Gentleman, 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 :-
My invention relates principally to the construction of rollers or wheels for small
articles such as for furniture castors, but it is applicable also to pulleys and articles
of a like nature.
In making such articles and carrying out my invention I propose to form same
in parts or halves which are stamped or pressed from sheets or discs of metal,
suitable shoulders or flanges being formed to strengthen the parts when joined
together by soldering, brazing or in other suitable ways.
To strengthen the article and to provide an increased bearing surface for the
spindle or shaft, flanges or turned in edges are provided about the central opening
through which the spindle or shaft is inserted. The stamping is preferably effected
by suitably shaped dies or plungers.
In order that the method of carrying the invention into effect may be clearly
understood reference is made to the accompanying drawings which form part of
this Specification, and which illustrate the invention as applied to the wheel of a
furniture castor, and from which the application to pulleys and the like will be
readily understood.
Fig. 1 represents in sectional elevation the two halves of the castor.
Fig. 2 represents the halves when placed together.
Fig. 3 is a side elevation, and
Fig. 4 represents a modification of the form of joint shown in Fig. 2.
Suitably shaped metal or other discs are placed between dies and stamped up
into the half wheels A A the centre haine pressed in to form an increased bearing

page_text: surface B for a spindle or shaft. The recessed half wheels are then placed in a
lathe chuck and turned so as to form inside and outside recesses and shoulders c, d.
The halves are then pressed and soldered together, and if desired may be held in a
vice until the solder is thoroughly hard. The external face of the joint may then
be polished, lacquered, or otherwise finished as desired.
In the form of wheel shown in Figs. 1 and 2 the two halves are counterparts so
far as the stamping is-concerned, and consequently both can be made in one set of
dies. In the form illustrated in Fig. 4 nearly all lathe work is avoided, but the
halves not being counterparts two or more sets of dies are necessary.
It will be evident that other forms of joint may be made, as for instance_a
V shaped recess in one edge and a corresponding projection in the other, or the
edges of the parts may be smooth or only slightly recessed internally, and a
supplemental ring or band may be used to effect the join, also that countersunk
screws may be employed to secure the halves of large wheels.
my said
Having now particularly described and ascertained the nature of
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improvements in rollers, wheels, pulleys, and like articles, which consist
in forming them in two parts provided with recesses and shoulders adapted when
fitted together to form a smooth external face, substantially as set forth.
2. The improvements in rollers, wheels, pulleys and like articles, which consist
in first stamping up the halves, then forming the recesses and shoulders therein,
and then securing said halves together, substantially as set forth.
3. The improvements in rollers, wheels, pulleys and like articles, which consist
in forming the parts thereof so as to produce a considerable bearing surface for the
shaft or spindle, said parts being also provided with recesses and shoulders, all sub-
stantially as set forth.
4. The improved roller, wheel, or pulley, substantially as described.
