FASTENER FOR MEETING-RAILS OF SASHES.

SPECIFICATION forming part f Letters Patent No. 370,560, dated September 27', 1887.

Application filed February 21, 1887. Serial No. 228,333. (Model.)

To aZZ whom it may concern.-

Beit known that I, ADoLPH RIPPrEN, a citizen of the United States, residing in Reading, Berks county, Pennsylvania, have invented certain Improvements in Sash-Fasteners, of which the following is a specification.

My invention consists of certain improvements in that class of sash-fasteners in which a hooked latch-bolt on the lower sash is swung around into engagement with a hooked keeper on the upper sash, and the two are then drawn together, so as to bring the sashes into contact, said sashes being thus not only locked together, but also prevented from rattling.

My improvements comprise certain constructions and combinations of parts, fully set forth and claimed hereinafter, the results of the improvements being that the fastener presents a ener detached from each other.

neat external appearance, is powerful in its action, yet easy of operation, andwhen in the locked position effectually prevents either the spreading apart of the sashes or the forcing back of the latch-bolt out of engagement with the keeper.

In the accompanying drawings, Figure l is a perspective view of my improved fastener, parts of the upper and lower sashes being shown by dotted lines. Figs. 2, 3, and 4 are sectional pla-n views of the fastener, showing the parts in different positions. Fig. 5 is a perspective view showing the parts of the fast- Fig. 6 is an inverted perspective view of the latch-bolt,

and Fig. 7 is an inverted perspective view of tubular stud and having a head, d, which iscontained in arecess, e, in the top of the hood,

the pin being secured to the base by riveting the lower end of the same, or by providing the same with a suitable nut or other retainer. On the base are also three studs, f g 7i, the purpose of which will be explained hereinafter.

The latch-bolt B has a projecting hook, 7c, at the outer end, shoulders It k3 upon opposite sides, a recess, 7c', in one side, a central elongated slot, z', and lugs j and m projecting from its upper face, while in the under side of said latch bolt is a radial groove, h', and a segmental groove, f,- the outer Wall of the lattewi1 having a notch, f2.

The cam-disk D has a projecting arm, D', by which the manipulation of the disk is eected, and said disk has a cam-slot, j', while on the under side of the disk is a beveled shoulder, m', terminating at the ends in recesses ml and ma.

The hood F has in its side wall a recess for the reception of the arm Dlof the cam-disk, and a slot, F', for the projecting latch-bolt, this slot being of sufficient dimensions to permit the necessary movement of the latch-bolt.

The hood, however, partakes of the rotating movement ofthe cam-disk. Hence this slot can be much less in dimensions than if the hood were stationary.

A spring, H, is interposed between the under side of the hood and the top of the camdisk D, so as to press said cam-disk firmly upon the latch-bolt and the latter upon the base-plate, and thus prevent any loose fit of the parts, such as would cause them to rattle.

When the fastening is open, the parts ar-e in the position shown in Fig. 2, and in order to close the fastening the cam-disk is turned in `the direction of the arrow shown in said figure. cause the shoulder m on the under side of the cam-disk to bear upon the lugv m of the latchbolt, and thereby cause the turning of said bolt with the disk, any longitudinal sliding movement of the bolt being prevented by contact of the segmental inner end ofthe bolt with the stud g on the base-plate, and also by engagement of the stud j' on the base-plate with the segmental groovej in the under side The first effect of this movement is to of the latch-bolt. The rotating movement of the latch-bolt with the cam-disk continues until the projecting stem of the bolt strikes the keeper G, as shown in Fig. 3, whereupon a longitudinal-sliding movement is imparted to the bolt by reason of the action of the camslot j upon the lug j, which projects from the upper1 side of the bolt. rlhis longitudinalsliding movement is permitted when the parts reach the position shownin Fig. 3, for the stud g of the base-plate is now in line with the recess k of the bolt, the stud It is in line with the groove 7L', and the stud f is in line with the notch f2 at the end of the groove f. When the parts reach the position shown in Fig. 4, the fastening ofthe sashes is completed, the longitudinal-sliding movement ofthe bolt after its engagement with the keeper having had the effect of drawing the meetingrails of the sashes closely together.

Any attempt to pry the sashes apart without turning the cam-disk backward is resisted, first, by the engagement of the lug j of the bolt with the cam-slotj of the disk, and, second, by reason of the fact that the lug m of the bolt occupies a position in the recess m2 in the under side of the cam-disk, which recess is diametrically in line with the pivotal center of the diskfso that separation of the sashes is resisted by the full strength of the tubular pivotstud and latch-bolt.

The turning of the latch-bolt backward, so as to free it from engagement withv the keeper, is also effectually prevented by reason of the engagement of the stud 7L on the base-plate with the groove 71. in the under side of the latch-bolt, and by the presence of the stud g in the recess 7c of the bolt.

A positive stop limits the movement of the latch-bolt in either direction, and the movement of the cam-disk islikewise limited. Thus the forward-swinging movement of the latchbolt is limited by contact of the projecting stem of the bolt with the lug f on the base,

irrespective of the stop provided by the keeper G, as reliance cannot always be placed upon the latter being in proper line to serve of itself as a stop for the bolt.

The inward-sliding movement of the-bolt is restricted by contact of the shoulder k2 with the stud g on the base, and the outward-sliding movement is restricted by the contact of the stud f of the base with the inner wall of thesegmental groove f of thelatch-bolt, while the backward-swinging movement of said bolt is restricted by contact of the shoulder 7c3 of the same with the stud h on the base. The forward movement of the cam-disk D is restricted by the lugs j and msof the bolt, which respectively enter the slot j and recess m2, the contact of the side wall of the hood F with the back of the latch-bolt stem also serving to restrict this movement, while backward movement of the cam-disk is arrested by the stud m entering the recess m3 in the under side of the disk, and by the contact of the side wall of the hood with the front of the latch-bolt stem.

The hood F constitutes an important fea` ture of my improved fastener, as it covers, protects, and conceals the working parts of the fastener, and, as it is a separate piece, 1t is susceptible of being turned in a lathe and polished or otherwise ornamented, so as to impart a neat and attractive appearance to the fastener.

Strength, stability, durability, and ease of operation also characterize my improved fastener, owing to the precautions which I have taken for keeping the latchbolt properly centered during its swinging movement, to the fact that each movement is effected by a special cam, and because positive stops are employed to limit the movement of both the latch-bolt and cam-disk and to prevent either the longitudinal or swinging movement of the bolt without the operation of said cam-disk.

I claim as my invention- 1. The combination, in a sash-fastener, of the base-plate, the latch-bolt, and the camdisk, with a revolving hood which' covers and protects the cam-disk and the hub of the bolt, said hood being separate from the cam-disk and bolt and being slotted for the reception of the projecting stem of the bolt and the projecting arm of the cam-disk, all substantially as specified.

2. The combination of the base-plate having studs f and g, with the latch-bolt having a segmental end for bearing against the stud g, a segmental groove for the reception of the stud f, and a notch through which said stud can enter or leave the groove, all substantially as specied.

3. The combination of the base-plate having a pivot-stud, the latch-bolt having an'elongated slot for the reception kof said stud and having two projecting lugs upon its upper face, and the cam-disk having a shoulder for acting upon one of said lugs to turn the bolt, and a cam-slot for acting upon the other lug to impart a longitudinal sliding movement to the bolt, all substantially as specified.

4. The combination of the base-plate having a pivot-stud, the latch-bolt having an elongated slot for the reception of said stud and having projecting lugs upon its upper face, and the cam-disk having a slotd for acting upon one lug to move the bolt longitudinally, and a shoulder which acts upon the other lug to turn the bolt and terminates in a recess for the reception of said lug when the turning movement is completed, all substantially as specified.

5. The combination of the base-plate having a pivot-stud, the locking-bolt having an elongated slot for the reception of said stud and having projecting lugs upon its upper face, and the cam-disk having a slot for acting upon one lug to move the bolt longitudinally and a shoulder for acting upon the other lug to turn the bolt, said shoulder ter- ICO IIO

minating at its opposite ends in recesses, one of which receives the lug when the disk has reached the limit of its movement in one direction, the other receiving the lug when the disk has reached the limit 01" its movement in the opposite direction, ail substantially as specified.

In testimony whereof I have signed my name to this specification inthe presence of two subscribing Witnesses.

ADOLPH RIPPIEN.
