'Letters Patent No. 109,362', dated November 15, 1870; antedated November 5, 1870.

IMPROVEMENT IN SSH-HOLDERS.

The Schedule referred 'to in these Letters Patentand making part of the lame.

vexact description thereof, reference heilig had to the accompanying drawing and lto the letters of reference marked thereon making apart ot' this specication. y

The nature of my invent-ion consists in the construction and arrangement of a sash-stop and lock, composed of an eccentric covered with gum, rubber, or leather,.being pressed toward the sash by a spring on the top end of which is a hook, which answers as a fastener to hold the sash down when closed. i Y

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in whichv Figure 1 is a longitudinal vertical section, and

Figure 2, an inside' view of my stop and lock.

A represents a portionof a window-fram c, and

B, a portion of the window-sasli.

In the inner edge of the frame A is a recess, into which is inserted a metallic box, C, and in this box is placed a solid eccentric, I).

The shaft upon which this cccentric'is placed pass-v es through on the inner side of the frame A, and is at its end providedwith a button, E,'by means of which the eccentric is turned.

The outer circumference of the eccentric D is surrounded by a band, n, of gum, rubber, or leather.

To the edge ot' the frame A is secured a spring, G, at one end, the other end. of thespring heilig provided with a hook, l), as shownr in fig. 1.'

The spring Gr is also slotted, so that the eccentric D may project through ythe same. 7

Through theprjecting end 'of' the eccentric D is passed a pin, fi, on the outer .side of said spring, and against which 'the spring bears .to yforce .the ecceitric outward. -Y

The edge of the sash Bis grooved itsentireheight, and at a suitable point in said groove is la recess for the hook b oi' the spring G. to enter into when the sash is closed to lock the same. 4 Y

At a suitable point in said grooveis also an indentation for the outer end of the eccentric'to enterinto, so as to allow the hook b to enter the recess formed for it. l

Ihe two great advantages of my sash-stop and lock are simplicity and durability.

. y Simplicity, from the fact that it-has but two directV parts to accomplish two direct objects, namely, as a stop to hold the sash at'any point rmly, and yet with such anelasticity as not to render the hold harsh, (in which case a continual wearing of both stop and sash must occur.)

It has but one spring, which forces both stop and lock to work.

This spring is not of the spiral form, but is made of either spring-steel or brass, and not one-twentieth part of the capacity of' the spring is required in or' der to forceboth stop and lock to do their respective work, and make both sure.

Ihe principle of the stop is of eceentricvform, closing up all the open space between the sash and post or frame in the form of a wedge, or as a key-stone closes an arch.

The elastic vsubstance which covers the stop will not admit of a griping hold, as heretofore referred to. .Y

' The lock is simple, from the fact that it is connected firmly at the top ot the spring in the form ot a hook, and so arranged that, when the sash is raised, it leaves the sash entirely, leaving no chance for wear of the'sash from the hook, and on leaving its position as a lock, the spring assumes its duty to keep the stop against the sash, so as to make it sure of working.

,In point of durability, the stop is made solid, of cast-brass or iron, oblong or egg-shape.

rIhe pressure or strain being no more than the weight of the sash, but little strength is required, when it hasstrength enough tosnpport fifty times the weight of an ordinary sash without overtasking it.

The lock and spring combined are durable, from the fact that the full capacity of the spring is not required, and when once locked the strain, when attempting to force the sash up, comes on the screws or where it isfastened to the post or frame, and on the hook, but so close to'the spring that the strain is so divided as to make the principle the same as'trying to force the spring in two in the center. p

' This stop and lock are particularly adapted for railroadcars, but can also be used on windows in houses, &c.', and can readily be changed to suit both an upper and lowersash.

Having thus fully described my invention,

What I claim as new, and desire to secure by Let tersPatent, is

The combination ot the solid eccentric D provided with elastic band a, and pin fl with the slotted spring G provided with hook b, lconstructed and arranged to operate substantially in the manner and for the purposes herein set forth.

In testimony that I claim the foregoing, I have hereunto set my hand this 7th day of April, 1870.

EDMUND H.' WHEELER.
