An Improved Drop-hammer Belt.
Year: 1898

page_text: An Improved Drop-hammer Belt.
I, JOHN TAYLOR, of 7, Strand Street, Liverpool, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to belts of drop-hammers, by which the hammer-
head or block is raised and allowed to fall, and which, in the raising action,
generally passes over a wheel or pulley.
The chief object of the present invention is to provide an improved belt for
this purpose, which will resist the stress and strain due to the alternations of
movement when in operation, and the tearing and destructive actions which go
on in, and happen to, the ends of the belts, where it is fastened to the hammer
head or block at the one end, and the lifting device or part at the other.
According to this invention, the body of the belt is preferably composed of a
lamina of leather, and a lamina of canvas (or several of them), or of other suit-
able material; and the end of one layer or lamina of leather is taken and doubled
or folded down over the other, and is tapered off, or made taper, in a suitable
way, so that the combined lamina at the extreme end of the belt is thicker or
wider than within the end. The ends are thus inwardly wedge shaped or of
dovetail form. Then to the outside of these parts a metal plate in the form of
a loop is clamped, being held by rivets or bolts passed through the metal sheet
on either side, and the belt laminae between them.
The metal plates of which the loops consist, are suitably made of channel form,
with outwardly turned flanges at the outside edges.
The loops may be extended the full width of the belt, or a greater portion
thereof; and a metal link, through which the required attachments are to be
made, may pass through them.
The different laminae of the belt from end to end will be stitched and fastened
together in any suitable way, and made substantially one.
By these fastenings, the belt is secured to the lifting or pulling up device, and
to the hammer head or block below.
By this belt, made as described, the fastening parts do not tear the ends or
destroy them rapidly, as happens at present; and an efficient, and relatively long-
lived belt is provided.

I, JOHN TAYLOR, of 7, Strand Street, Liverpool, in the County of Lancaster,
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 has reference to belts of drop-hammers, by which the hammer-
head or block is raised and allowed to fall, and which, in the raising action,
generally passes over a wheel or pulley...
The chief object of the present invention is to provide an improved belt for
this purpose, which will resist the stress and strain due to the alternations of
movement when in operation, and the tearing and destructive actions which go
on in, and happen to, the ends of the belts, where it. is. fastened to the hammer
head or block at the one end, and the lifting device or part at the other.
According to this invention, the body of the belt is composed of a lamina
viz., lamina of leather and canvas or canvas only, or of other suitable equivalent
material; and at the ends one layer or lamina is doubled or folded down over
the other, and tapered off, or made taper, in a suitable way, so that the combined
lamina at the extreme end of the belt is thicker or wider than within the ends.
The ends are thus, inwardly, wedge shaped or of dovetail form. Then to the
outside of these parts a metal plate, in the form of a loop, is clamped, being held
by rivets or bolts passed through the metal sheet on either side, and the belt
laminae between them.
The metal plates of which the loops consist, are suitably made of channel form,
with outwardly turned flanges at the outside edges.
The loops may be extended the full width of the belt, or a greater portion
thereof; and a metal link, through which the required attachments are to be
made, may pass through them.
The different laminae of the belt from end to end will be stitched and fastened
together in any suitable way, and made substantially one.
By these fastenings, the belt is secured to the lifting or pulling up device, and
to the hammer head or block below.
The invention is illustrated in the annexed drawings; in which Figure 1 is
a side elevation shewing the belt with an attaching link at one end; whilst
Figure 2 is a side elevation, and Figure 3 a plan partly in section, shewing in
detail the constructions of the ends of the belt.
Referring to the drawing, in the case shewn the belt proper consists of two
Jaminae a, b, the former being leather, and the latter of canvas, such as is used
for belting, or both may be of canvas, or of other suitable material. a is a third
lamina tapered off as shewn from the outer end inwards; and in the case shewn
this third lamina is folded over. the end of the lamina b. The, extremities of
the belt are thus the thickest or largest part, diminishing to the point where
the additional lamina or folded-over part terminates; that is, they are wedge
shaped or of dovetailed form.
Onto the outside of these end portions, the clamp fastenings care attached by
rivets d, the ends of the clamps at c¹ being in the form of a loop or eye; and
to this eye, the attachments and parts to be used in connection with the belt
are secured.
In the case shewn, within the loop or eye c¹ there is a ferrule of metal e, and
it is held by the loop or eye, and through this ferrule one end of the link f
is passed, and to which the hammer head or block or other part is attached.
In the case shewn, the outer edges of the clamps c are turned out or beaded

page_text: at, and the corrugation or rib c³ is provided in the centre. By this con-
struction the eye or loop is given strength, and also the ferrule e is held in
position.
The laminae a and b are stitched together by copper or other suitable stitching
throughout their lengths, these being indicated by the dotted lines i.
By this belt, made as described, the fastening parts do not tear the ends or
destroy them rapidly as happens at present, and an efficient and relatively long-
lived belt is provided.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is :-
1. The herein described improved drop hammer belt, consisting of laminae of
material, having tapered or enlarged ends to which the end fastenings are
attached; for the purposes set forth.
2. An improved drop hammer belt consisting of multiple laminae stitched
together, and additional end lamina a tapered off, forming a wedge shaped or
tapered end; and the clamp fastening c of metal, rivetted or equivalently fastened
thereon; substantially as set forth.
3. The improved drop hammer belt comprising the multiple laminae portions, .
and wedge shaped ends, and fastenings secured thereon; particularly as set forth
with reference to and shewn in the drawings.
