UNITED STATES PATENT OFFICE.
JOHN MCQUILLAN, OF HEOKER, ILLINOIS.
sAsH-FASV'TEN ER.
SPECIFICATION forming part of Letters Patent No. 580,093, dated April 6, 1 897'. Application filed December 21, 1896. SerialNo. 616,509. (No model.)
To @ZZ whom if; may concern:
Be it known that I, JOHN MCQUILLAN,a citizen of the United States, residing at Hecker, in the county of Monroe and State of Illinois, have invented a new and useful Sash-Lock, of which the following is a specification.
The object of this invention is to provide a lock by which the upper and lower sashes of a window may be securely locked together and prevented from rattling.
The invention consists in certain novel features and details ofconstruction and arrangement of parts, as hereinafter fully described, illustrated in the drawings, and pointed out in the claims hereto appended.
In the drawings, Figure l is a plan View showing my invention in connection with portions of the upper and lower window-sashes and in the locked position. Fig. 2 is a plan view of the device unlocked. Fig. 3 is an end view. Fig. 4 is a plan view showing a modification. Fig. 5 is a bottom view of the locking device. Fig. 6 is a section on the line c c of Fig. l.
Similar numerals of reference designate corresponding parts in the several iigures of the drawings.
l and 2 represent the meeting-rails of the lower and upper sashes, respectively. To the rail I is iirmly secured by screws or other suitable devices a part of the locking device which consists of a plate portion 3, having an upwardly-extending projection, (indicated by 4,) which projection is wedge-shaped longitudinally and has one of its sides undercut, as indicated at To the rail 2 is secured a plate 8, having an upwardly-extending wedgeshaped projection 9, similar to the projection 4, having an undercut side IO. The plates 3 and S are so located as to bring their wedgeshaped projections opposite to each other when the sashes are closed.
ll represents the sliding clamp, which is provided with a longitudinal groove 12, of dovetail outline in cross-section, to fit over the projections 4 and 9 of the plates 3 and 8. An ear or lug 13 projects from the clamp, and to this lug the thumb-bolt 7a is secured.
The plate 8 is provided with an undercut groove having the straight portion 14 and the deflected portion l5. The thumb-bolt 7 has an enlarged end 7, adapted to slide in this undercut groove. The straight portion 14 of the groove is for the purpose of causing the clamp 1l to engage the projections 4 and 9 and slide on them, and the deflected portion 15 is for the purpose of withdrawing the clamp out of the way of the sash 2, and this deected portion may be at a right angle to the portion 14, as indicated in Fig. l, or it may be at an obtuse angle, as shown in Fig. 4.
The plates 3 and 8 are recessed on their lower faces forA the reception of a bolt 16, and said bolt 16 is provided with a finger-hold 17, which projects through a slot 1S in the plate 3. This bolt, when extended across on both rails l and 2, beneath the plates 3 and 8, serves as an additional lock to prevent the opening of the sashes.
From the foregoing description it will be understood that the projections 4 and 9 form,
when the sashes are closed, a dovetail tongue, slightly tapering or wedge-shaped longitudinally, and that the clamp 1l has a dovetail groove which also tapers slightly longitudinally. It is obvious, therefore, that when the clamp ll is slid on the projections 4 and 9 they will be drawn toward each other and thereby bring the rails l and 2 together to form a close joint, thereby preventing rattling and also leaving no space between them through which a device could be inserted to tamper with the lock. It is also obvious that the sashes are also securely locked against vertical movement and that the bolt 16 serves as au additional preventive to the vertical movement. j To unlock the sashes, the clamp is withdrawn from the projections 4 and 9 and moved along the groove 14 15 until it is entirely clear of the rail l.
It willbe apparent that changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.
l. The combination with the sashes of a window, of two plates secured to said sashes at their meeting-rails, said plates having upwardly-extending projections forminga dovetail tongue when they register with each other, and a clamp slidably connected to one IOO of the plates and having a dovetail groove to engage the projections, substantially as described.
2. The combination with the sashes of a window, of plates secured to said sashes at their meeting-rails, each plate having an lupwardly-extending projection tapering longitudinally, said projections being shaped to form a dovetail tongue when they register,
1o and a clamp having a dovetail groove tapersaid clamp and provided with an enlargement on its lower end to fit within the groove in the plate, substantially as described.
4L. The combination with the meeting-rails of two window-sashes each having a plate secured thereto, said plates being recessed on their lower Jfaces and one of said plates having a slot extending through it to communicate with the recess in its lower face, suitable means to lock the two plates together, a bolt working in said recesses, and a projection extending frorn the bolt up through said slot, substantially as described.
In testimony that I claim the foregoing as my own I have hereto axed mysignature in the presence of two witnesses.
JOHN MCQUILLAN.
