PROVISIONAL SPECIFICATION.
Improvement in the Slide Rests or Bed Slides of Lathes and similar
Machine Tools,
I, JASPER WETTER, Patent Agent, of 37 & 39, Essex Street, Strand, in the
County of London, do hereby declare the nature of this invention, a communica-
tion from Wilhelm von Pittler, Mechanical Engineer, of Gohlis, near Leipzig,
in the Kingdom of Saxony, to be as follows:-
This invention has for its object to construct the slide rests or bed slides of
lathes and similar machine tools in such a manner, that chips and tools which
are deposited or allowed to drop on the machine, will not come in contact with
the faced guide cheeks of the same.
In the accompanying drawings:-
Fig. 1 is a longitudinal section of a slide rest and bed embodying this invention:
along line Z-Z of Fig. 2: Fig. 2 is a section along line Y-Y of Fig. 1: Fig. 3
a plan of the slide rest and lathe bed; Fig. 4 a plan of the bed slide forming part
of the slide rest.
It is well-known, that the bed slide of the slide rest should be as long as pos-
sible, while the cross-slide should be as narrow as possible, in order that the
tail stock may be placed in close proximity to the head stock. The guide faces
of the lathe bed are exposed to chips dropping from the piece of work, which
chips may easily fall between the stationary and the movable guide. Moreover,
the guide faces may be damaged by tools placed on the same.
According to the present invention, the guide faces a¹ of the lathe bed a are
placed so far down that they can pass below the head stock and the tail
stock h, the long bed slide b of the slide rest extending immediately underneath
the head stock d, and a very large bearing or supporting surface b¹ being obtained,
although the top of the bed slide is brought close to the head stock d, and the
guide faces or cheeks a¹ of the lathe bed are always protected at the place, where
chips are likely to drop, so that the latter cannot get between the fixed and mov-
able guides. The shape of the uide faces may be varied according to require-
ments. The bed slide b is provided with apertures c, through which chips may
drop into a box formed in the lathe bed. The lathe spindle f is completely pro-
tected by the bed slide, so that chips dropping from the piece of work cannot.
touch the same.

page_text: tion from Wilhelm von Pittler, Mechanical Engineer, of Gohlis, near Leipzig,
in the Kingdom of Saxony, 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 for its object to construct the slide rests or bed slides of
lathes and similar machine tools in such a manner, that chips and tools which
are deposited or allowed to drop on the machine, will not come in contact with
the faced guide cheeks of the same.
In the drawings filed with the Provisional Specification:
Fig. 1 is a longitudinal section of a slide rest and bed embodying this invention,
along line Z-Z of Fig. 2; Fig. 2 is a section along line Y-Y of Fig. 1; Fig. 3
a plan of the slide rest and lathe bed; Fig. 4 a plan of the bed slide forming part
of the slide rest.
It is well-known, that the bed slide of the slide rest should be as long as pos-
sible, while the cross-slide should be as narrow as possible, in order that the
tail stock may be placed in close proximity to the head stock. For this purpose
the guide cheeks of the lathe bed on which the bed slide moves are generally
arranged outside the head stock and tail stock right and left of the same, and
the guides of the slide rest may be extended on both sides of the head stock or
tail stock, but must always be very narrow. The guide faces of the lathe bed
are exposed to chips dropping from the piece of work, which chips may easily
fall between the stationary and the moveable guide. Moreover, the guide faces
may be damaged by tools placed on the same.
According to the present invention, the guide faces of the lathe bed a are
placed so far down, that they can pass below the head stock d and the tail
stock h, the guide cheeks of the long bed slide of the slide rest extending
immediately underneath the head stock d, and a very large bearing or support-
ing surface being obtained, although the top of the bed slide is brought close
to the head stock d, and the guide faces or cheeks a of the lathe bed are always
protected at the place where chips are likely to drop, so that the latter cannot
get between the fixed and moveable guides. The shape of the guide faces may
be varied according to requirements. The guide pieces or cheeks 1 of the bed
slides are provided with apertures c, through which chips may drop into a box
formed in the lathe bed. The lathe spindle f is completely protected by the
bed slide, so that chips dropping from the piece of work cannot touch the same.
In some cases the bed slide may be made to extend underneath the tail
stock h.
Having now particularly described and ascertained the nature of the said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:-
:-
In lathes and similar machine tools, a bed slide having guide cheeks extend-
ing underneath the head stock d or the tail stock h, in order to protect the guide
faces a¹ of the lathe bed from chips which may drop on the machine, and at
the same to obtain a large bearing surface.
