New or Improved Means and Apparatus for Rasping Heated, Iron
or Steel.
We HENRY GREEN, of Ecclesfield Forge, Butterthwaite, near Sheffield, in the
County of York. Manufacturer, and THOMAS HURDLEY, of Grange Lane Forge,
Grange Lane, near Rotherham, in the County aforesaid, Manufacturer, 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 relates to means and apparatus for rasping heated iron and steel.
Hitherto the rasping of heated iron or steel has been mostly performed by the
forgeman or smith using an ordinary rasp and pressing it backwards and forwards
upon the heated iron or steel. The object of our present invention is to arrange an
apparatus which will perform the rasping of heated iron or steel in a more efficient
and economical manner than by the means hitherto employed; to attain which we
employ apparatus as illustrated in the accompanying sheet of drawings, in which
Fig. 1 is a side elevation of our improved apparatus,
Fig. 2 a cross sectional elevation taken on line a-a of Fig. 1, and
Fig. 3 a cross sectional elevation taken on line b-b of Fig. 1.
Similar letters of reference denote corresponding parts in each view.
We mount upon a suitable frame or bracket C, arranged with bearings e¹, a
suitable horizontal spindle D, having at one end fast and loose pullies c² and c³ for
driving the same, and at the other a disc E, to the outer side of which is secured by
means of countersunk bolts e³, or other ordinary means, segments of a circular disc
rasp G. An adjustable bench H is carried upon the frame c, and has pivotted to it
a pressure lever h', and upon the bench H is also arranged a feed table or
traveller 2, which may be operated by any ordinary feed mechanism as will be well
understood. Upon the spindle D and preferably between the bearings c¹ we secure
a drum J, made with a series of longitudinal grooves j¹ (see Fig. 3) upon its
periphery which receive suitable wedge shaped rasps G. Under the drum J aud
upon the bracket or frame C we arrange an adjustable table or bench H', also
arranged with a travelling table 2, and any ordinary feed mechanism. In order to
rasp a piece of heated iron or steel K we either place it on the feed table with
its part to be rasped bearing against the disc rasp G and its opposite part receiving
pressure from the pressure lever ', and we press it along, or the feed mechanism
travels it along the table H, and as it travels along one side becomes efficiently
rasped; or the piece of heated iron or steel K may be placed on the table H', and
forced under the drum J when the rasps G₁ will efficiently rasp the upper side of
the said piece of heated iron or steel K. It will be obvious that our improved
apparatus could be made in a variety of forms without departing from the essential
feature of our invention namely the use of revolving rasps for rasping heated iron
or steel, therefore
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 :-
1. The means of rasping heated iron and steel substantially as described.
2. In apparatus for rasping heated iron and steel the combination of a segmental
or other disc rasp G with a revolving disc E substantially as described and
illustrated.
3. In apparatus for rasping heated iron and steel the use of a revolving drum J
having rasps fitted to its neriphery substantially as described.

page_text: 4. The combination of a mounted rasp E with an adjustable table or bench H
and pressure lever h¹ substantially as described and illustrated and for the purpose
stated.
5. The combination of a revolving drum J mounted with rasps G¹ with an
adjustable bench H* substantially as described and illustrated and used for the 5
purpose stated.
