JOHN CHANTRELL, OF READING, PENNSYLVANIA, ASSIGNOR TO THE READING HARDWVARE COMPANY, OF SAME PLACE.

FASTENER FOR MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 362,936, dated May 17, 1887. Application filed January 14, 1887. Serial No. 224,819. (Modem To aZZ whom it may concern:

Beit known that I, JOHN OHANTRELL, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Locks for Meeting-Rails of Sashes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the class of fasteners for meeting-rails of sashes in which a swinging catch pivoted to one of the rails engages a stump upon the other rail and then acts to draw the two meeting-rails together, the construction being such that the catch is locked at both extremes of its movement.

The object of my invention is to simplify and strengthen the construction, while at the same time the cost of production shall be reduced. XVith these ends in view I have devised the novel construction of which the following description, in connection with the accompanying drawings, is a specification, numbers being used to indicate the several parts of the device.

An important feature of my present construction is that the swinging catch may be applied with equal convenience to either the lower rail of the upper sash or the upper rail of the lower sash. I have shown it in the drawings as applied to the lower rail of the upper sash, the stump being upon the upper rail of the lower sash.

Figure l is a plan view showing the swinging catch as locked in its disengaged position; Fig. 2, a plan view, partly in section, showing the swinging catch as thrown into engagement with the stump, the final movement to draw the two rails together and lock them not having been made; Fig. 3, a similar view showing the meeting-rails drawn together and the parts as locked in the engaged position; Fig. 4, a section on the line w w in Fig. 1; Fig. 5, an inverted plan view of the operatingknob or thumb-piece detached; Fig. 6, a plan view, and Fig. 7 an edge view, of the carrying-disk detached; Fig. 8, a plan view, and Fig. 9 an edge view, of the catch detached; Fig. 10. a plan view of the base-plate detached; Fig.

11, a section corresponding with Fig. 4, illustrating a slight modification in construction; Fig. 12, a view corresponding with Fig. 5, illustrating the modification in construction; and Fig. 13 is a plan view of the base-plate in the modified form.

1 denotes the base-plate, which, as already stated, may be attached to either sash, but is shown as attached to the lower rail of the upper sash, and is provided with notches 2 and 3, for a purpose presently to be explained.

at denotes the carrying-disk, which is provided with a cross-slot, 5, and a notch, 6, the purposes of which will presently be explained.

7 denotes the swinging catch, which is provided with a hook or projection, 8, to engage the stump, a longitudinal slot, 9, a lug or pin, 10, upon its upper side, the purposes of which Will presently be explained, and a lug or pin, 11, on its under side, which is adapted to engage notches 2 and 3 in the base-plate,whereby the catch is locked either in its engaged or disengaged position.

12 denotes the operatingknob or thumbpiece, the base of which is preferably made circular and of just sufficient size to cover the carrying-disk. It is provided with a central stud, 13, which passes through slot 9 in the catch, central openings in the disk and the base-plate, and is headed upon the under side of the base-plate, as clearly shown in Figs. 4 and 11, at 14, being left free to turn in the base-plate and the disk.

15 and 16 denote inclined slots in the under side of the operatingkuob, the outer ends of which are connected by a curved slot, 17. These slots are engaged by pin 10 on the up per side of the catch, slot 15 acting to draw the catch inward and lock it in its disengaged position and slot 16 acting to draw it inward and lock it in its engaged position. It will be seen that pin 11 is made long enough to extend below the disk and engage the edge of the base-plate and notch 2 when the catch is swung to the disengaged position, and to engage projection 18 and notch 3 when swung to the engaged position. This, however, is not essential, and, if preferred, pins 19 may be provided on the base-plate as stops for the catch at the two extremes of its movement.

It will of course be understood that the catch ing-knob is provided on its under side with pins 21, which engage corresponding holes, 22, in plate or disk 20, the said disk of course being made the same diameter as the base of the operating-knob, and a curve, 23, being provided between slots 15 and 16, over which thepin rides while passing from one slot to the other.

24 denotes a stump, which may be of any suitable or convenient shape, is preferably made upon a base-plate, and is attached to the meeting-rail of the other sash in position to be engaged by the catch to draw the sashes together and lock them.

It will be seen that the act of assembling is reduced to the heading of a singlestud. The disk and catch are simply placed in the positlons shown and the stud upon the operatingknob passed through the catch, disk, and base-plate, and'headed on the under side of the latter.

The operation is as follows: Suppose the parts to be in the position shown in Fig. 1- that is, locked in the disengaged positionthe catch being drawn inward, the central stud at the end of slot 9, pin 11 engaged in notch 6 in the carrying-disk and notch 2 in the base-plate, pin 10 lying at the inner end of slot 16, and the catch resting against one of the pins 19. Rotation of the operating -knob causes pin 10 to ride out of inclined slot 15, which of course throws the catch out radially and disengages pin 11 from notches 2 and 6, slot 9 in the catch permitting ample movement in or out. As soon as pin 10 passes out of slot 15, the outward movement of the catch ceases and the pin travels along slot 17 until it reaches the straight wall at the outer end of inclined slot 16. Continued rotation of the operating-knob now causes the catch to swing around toward the front until the catch strikes the other of the pins 19, if used, and pin 11 strikes projection 18 on the base-plate. The parts are now in the position shown in Fig. 2, the catch being engaged with the stump, but not drawn in and locked. Continued rotation of the operating-knob now causes pin 10 to ride down to the end of inclined slot 16, which acts to draw the catch inward until the hook engages the stump and pin 11 again engages notch 6 in the carryingdisk, and also notch 3 in the base-plate, thus locking the catch in the engaged position. The movements to unlock the catch, throw it to the disengaged position, and lock it there again are simply the reverse of those just described. Movement of the operating-knob backward causes pin 10 to ride up the straight wall of inclined slot 16, which throws the catch outward, disengaging pin 11 from notches 3 and 6. After passing out of slot .16, pin 10 travels along slot 17 until it reaches the outer end of inclined slot 15.

Continued rotation of the operating-knob swings the carrying-disk and the catch around until the latter strikes pin 19, and then draws it inward aspin 10 passes to the inner end of inclined slot 15, which causes pin 11 to engage slot 6 in the carrying-disk and slot 2 in the base-plate, thus locking the parts in the position shown in Fig. 1.

It will be seen that the catch 7 is guided in its longitudinal movements by the slot or.

groove 5 in the carrying-disk 4, the said catch, when disengaged from the locking slots and notches 15, 16, 2, 3, and 6, being held free from lateral movements by the said groove 5 in the said disk. It will thus be apparent that without the said disk, which carries or supports and turns with the catch, there would be nothing but the pin 13 to prevent lateral movement of the catch when unlocked, and it would therefore not be so steadied as to be practically operative.

It will of course be understood that the details of construction may be varied within reasonable limits without departing from the spirit of my invention.

I claim-- l 1. The combination,with the base-plate having a locking-notch, as 3, of the carrying-disk 4, having the cross slot or groove 5 and notch 6, the catch 7, fitted to slide in the said slot or groove and having the pin 10 on its upper side, the pin 11 on its under side, and the longitudinal slot 9, and an operating-knob or thumb-piece, 12, having an inclined lockingslot, as 16, a curved slot, as 17, and a central pin, 13, substantially as set forth.
