COMPLETE SPECIFICATION.
Templet for Drilling Wooden Railway Cross-sleepers.
I, LUDWIG GROSS, 661, Bahnhof, Mersig on the Saar, Germany, First Class
Station Master on the State Railway, do hereby declare the nature of this inven-
tion 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 an apparatus for enabling the wooden cross sleepers
laid down on railways to be previously ready drilled, in case of new construction,
reconstruction, or the interchanging of single sleepers, this arrangement being
suitable for all gauges and for every kind of bed plate.
As compared with the methods hitherto employed, that is those carried out
without the templet, there is a considerable saving of time and labour, the work,
besides being much more accurately performed.
The fact that the sleepers can be prepared apart from the rails is one of very
great importance, when an interchange of sleepers is effected in connection with
rails over which trains are being run. It being possible to have the sleepers
ready drilled before fixing them, it is also possible to employ a drilling machine,
which certainly produces better work than can be done by hand.
In the accompanying sheet of illustrative drawings;
Fig. 1 is a front view
Fig. 2 a plan view of the templet.

The templet consists substantially of a rail or bar composed of two parts and
longitudinally adjustable, to the end of which the pattern plates or templets are
removably attached. The principal part a formed of angle iron carries a pattern
plate S, and serves as guide for the other part b which is provided with a second
pattern plate S¹. At the left hand extremity, the screw bolts a² pass through
the flat iron additional piece a¹, which is of the same thickness as the part b of
the rail or har. By means of these screw bolts, the templet is removably fixed,
this being effected with the assistance of the flat piece s riveted to S. Near its
centre, the rail or bar a carries the block or trestle with the nut for the adjusting
screw C. Further to the right, on the vertical portion of the angle iron rail or
bar a is the scale d, the division of which is 0-40 millimetres. The zero point
corresponds with the normal gange of way. Finally, the screw bolts e for guiding
and fixing the second part 6 of the rail or bar are fastened to a. The part bis
made of flat iron and carries on its outer end the bolts for fixing the second
pattern plate, and the piece s¹. Further on in the part b the pointer which
acts in conjunction with the scale d is seated, and is held firmly at the end of
the block or trestle c¹, which receives the end of the adjusting screw C. Slots e¹
in surround the bolts e. When the nut is loosened, the adjusting screw C
can be turned and, with the assistance of the scale, the effective length of the
apparatus be fixed, whereupon the nuts are screwed up.
The pattern plates S S¹ correspond with each other. and with a certain form
of the bed plate, of which there about 15 to 20 sorts. The perforation correspond-
ing with the particular forms of bed plates is suitably indicated in a shield or

page_text: plate on each pattern plate or templet by figures such as 6. The pattern
plates or templets are furnished with recesses which define the gauge of way.
In addition to this the pattern plates or templets have holes in them, correspond-
ing with those to be drilled in the sleepers, preferably not of the same size how-
ever, as the centre must first be ascertained, but about 1 millimetre wide, in
which a pin-punch for marking the holes is inserted.
The apparatus is applied in the following manner:
For the normal gauge of way, the pointer is brought to or zero on the scale,
by turning the adjusting screw to the right. After the two nuts e² have been
loosened, the slide, with the pointer, moves to the right and simultaneously there-
with the right hand pattern plate or templet S and the gauge of ways, so that
any amplification of gauge necessary at curves for the perforation of the sleepers
as likewise for the gauge of way can be obtained. When the right gauge has
been determined, the two nuts are screwed up, and the marking of the sleepers
can be commenced, provided that the proper pattern plates or templets for the
bed plates are also introduced and firmly screwed.
The workman with the templet lies preferably on the sleeper and holds it fast,
whilst another workman with the prick-punch marks the holes to be drilled; two
other (or the same) workmen operating the drilling machine. In this manner, a
large number of sleepers, which have the advantage of keeping the rails exactly
to the gauge of way, can be made ready in a very short time. The changing of a
part of the templet requires but little time, the apparatus thus being, so to
speak, always ready for use.
It is obvious that, without departing from the scope of the invention, modifica-
tions could be made in many parts of the apparatus having the form here
described and illustrated, for instance, in the external form of the parts of the
rail or bar, in the mutual guiding, the adjustment and so on.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
-
1. Templet for drilling wooden railway sleepers, distinguished by a rail or bar,
consisting of two parts, adjustable in relation to each other and variable in length,
to the ends of which the interchangeable pattern plates with recesses for indice-
ting the gauge of way, and holes for the marking of those to be drilled in the
sleepers, are fixed.
2. A modification of the templet for drilling wooden railway sleepers, claimed
under Claim 1, distinguished by the part (a) of the rail or bar with screw bolts a²
for fixing a pattern plate S, a block or trestel e holding the nut for the adjusting
screw C and a scale d the nil or zero point of which corresponds to the normal
gauge of way, a second part b of the rail or bar, longitudinally adjustable on the
first, guided by slots and screw bolts e and fixed by means of the last named,
with screw bolts 1 on the outer end for fixing a second pattern plate S', with a
pointer acting in conjunction with the scale d and a block or trestle e' in which
the adjusting screw C is held, and interchangeable pattern plates or templets S S¹
furnished with recesses for determining the gauge of way, and holes for mark-
ing those to be drilled in the sleepers.
