IMPROVEMENT IN sAsH-HoLDERs Een RAinRAp-CRS.

The Schedule referred to in theseLetters Patent and making part of the same.

We, ADAM LOEFFELHOLZ and ANTON Parnu, of l the city of Milwaukee, in the State'of Wisconsin, have invent-ed certain Improvements on Locks and Fasteners for Railroad-Car Window-Sash and Blinds,

of which the following is a specification.

The object of this invention is to provide the sashv of the car with an economical and useful lock or fastener, having as a leading feature the ready and easy aixing or attaching ofthe sash in the frame, and the ready detaching thereof, in addition to the usual features of such fasteners, of securing the sash, when down or when up, and of holding the sash at interme-` mediate points of elevation between the lower and upper partsof the frame and consists in an arrangement of a tumbler having a key-hole, in combination with the lift and levers, whereby, when the lift is elevated, the keyhole is exposed, allowing the key to be pnt in use, and to s0 further withdraw the bolts as to allow of the detaching of the sash 'or blind.

Explanation of 4the Drawing.

Figure l isa perspective view showing the position of the lock on the blind or sash. l

Figure 2, plan showing grooves for the bolts and notches in the iframe for fthe-ends of the bolts,secnring the blinds or sash in place whenK closed-or opened.

Figure 3, front plate ofthe lock, with the key, and claspior the ends of the bolts, shown by front View and by section.

Figure 4, internal arrangement of the parts.

Figure 5, sectional view, showing kneed bolts and lift.

Figure 6, view of the'back plate of the lock.

Figure 7 section through the center of the lock, with space for the bolts. p I

Figure 8, section showing the ends of the bolts and lift.

Figure 9, section showing .the position of the partsv by action of the lift for raising or lowering the blind or sash.

Figure 10, section showing the position of the parts by action of the key, which admits ef the removal oi" the sash or blind when so desired.

The. other unnumbered views of parts will readily berecognized as v1ews of detached pieces or parts.

The letters on the dra-win g refer to the several parts thus.

A, front plate of the lock.

B, back plate of the lock.`

0, lift. l

d, angle-levers, face view.

e, angle-levers, edge view.'-

f, pin for angle-levers,- which levers actuate the bolts g, bolts, kneed at eachend.

h, recess on the inner ends of the bolts for the ends ofthe angle-levers.

fi, front side and' section of the tumbler with the key-hole.

k, pin of the tumbler, operatingiin and witlrthe lift.

piece.

m, slot-inzthc lift-piece for the guide-piece. u, key-hole in the tumbler. o, springs for the bolts.

p, grooves in the frame, in which the end of the bolts slide.

r, notchesin the frame holding the sash or blind in,

place, either up or down.

Other-'notches may be at such intermediate pointev thus the sashprblind may be in conditionfto be raised Y or lowered, and when the pressure from the litt-is removed the springs will ,come intoplay and force ontv the bolts, so that thesash or blind will be held closed or opened, as may be desired; v

In'order to act still `further upon theholts, so as to relievetheir ends from Athe recesses in the frame, and' allow of the detaching'andremoval of thesash or blind.

from the frame, when the-lift` O is fully elevated' the key is inserted, and then, by the action ot the key on the tumbler fi, the bolts are drawn further inward, f and the ends of the'boltsremoved fromtthe recesses.

We are aware that an arrangement of springs and levers, to be actuated by a .thumb-piece or lifts, or by a key, has been used to operate the bolts of sash-holdgrs, and we therefore do not claim such arrangement; ut-

What we do claim is- An arrangement `of lifts, levers, springs, and bolts, in combination with a tumbler, fi, to be operated upon bya key, for the purpose of allowing the sash to be detached or removed from the frame, substantially as herein recited. v lslhis specification signedl this 17th day of January,

lADAM LOEFFELHOLZ.
