narran HENRY c. irnosr, or nr. Paso, TEXAS.
Application led April 17,
To all whom t may concern Be it known that i, HENRY C. Tnosnfa citizen of the United States, residing at El` Paso, in the county of El Paso, State of Texas, have invented certain new and useful improvements in ifiutoniatic interlocking .-fiittachments for VindowSashes; 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 saine. n
My invention relates to improvements in automatic interlocking attachments for usein connecting sliding window sashes, or the like, to each other so that the two maybe moved asone, but at the same time may be held in the predetermined relation to each other; thus permitting the s'ashes to be slid together up or down, leaving an air space below or above, or both belowv and above, the interlocked sashes.
' My invention will be more fully under-y of the arrows, the framework of the window being omitted for the sake of clearness in the drawings, and the partsbeing shown on a larger scale.
Figure 8 is a similar view to Fig. 2, eX- cept that the two sashes have been moved relative to each other, and are in the interlocked position, but both'may now be moved by pressure applied toeitherone.
Figure 4 is a view of the parts shown in Fig. 3, as seen from the right of said figure.
Figure 5 is a similar view to Fig. 4 but shows the parts inthe position just before the sashes are iiiterlocked.
Figures 6 and 7 are detail views showing on a larger scale the voppositely disposed trip plates which areused in my invention.
Figure 8 is a detail showingk one of the pendulum locks and the strip carrying th same used in my invention. Y
Figure 9 is a view of the'device shown in Fig. 8, as seen from the left of said fgure,.the pendulum lock being shown in usual way.

full lines in the inoperative position and in .dotted lines in the operative and displaced positions, respectively.
yFigure l() is a similar view to Fig. 2, but
shows the trip plate applied to the lower sash, and the pendulum lock applied to vthe upper sash, certain details being slightly altered from lthe preceding gures.
iiigure il is a detail showing a modified forni of trip plate which may be used in my invention; and i yFigure l2 shows a modied form of pendulum lock which may be used in connection witli'the 'trip plate shown in Figs. .l toll inclusive. y f
K fr represents the window frame which maybe ofthe usual or preferred construee tion provided with the usual guide strip or separating strip a, which is mounted between tlie'sashes, and is shown .only in Figs. i andy 5. This separating stripis a com-y mon .expedient 'with 'window frames, and
is not shown in Figs. 2', 3 and l0 in order to more clearlyrbring fout the other parts.
B represents the lower sash `of :the window,` and C theupper sash ofthe window which is ymounted to slide vertically in the iis thus described Vthe `parts Aare all old and well known in the art, and it is my purpose to. apply the invention to windows and window frames of standard construction without requiring any alterations inA the manufacture of the same by the builder or yContractor. My invention is more especiallyintended to provide the removable attachnient or attachments vwhich will now be described. e 1 i Y i in Figs. l tot i have shown mounted on opposite sides of the -upper window sash C the reversely disposed tripplates'l) and D which are adapted to be respectively engaged bythevlugs F, carried by the pendulum locks F, which are pivoted tothe strips E, attached to the lower window sash.
As will be shown later, it is immaterial whether the trip plates be attached to the upper sash and the pendulum lock to the' through to the upperfsash frame; These screws pass through perforations (Z in the CJi base plate D2. rlfhis base plate is provided with the upwardly projecting portions DE i 4 anu D ing the ca laces cl2 'terminating inthe hook al, which hooi; iorins the outer wall of the poclet di, which pocket is adjacent to the rib di whose end is ,'ire't'erablyrounded somewhatas at d". The oppositely disposed projectingportion D4 is provided with similar, but reversely disposed, wedge portions du, dlg, (Z13 anddlt, andwith a rib 651.5, preferably rounded at am. tween these ribs Z5 and d is a passage or channel D".
The construction of the two trip plates D and B is the saine, except that the parts are reversed as shown in Figs. G and 7. rlfhe locking` arrangement coacting with the trip plate comprises the metal strip E which is provided with a tail e, perforated, as at e', to receive the screws Gr by means of which the strips E may be fastened to the lower sash of the window. The strip lil is bent outwards, as at e2, and is provided at its upper end with a loop e3 through which passes the bolt et, to which the stem ot the pendulum lock F is pivoted. This lock carries the loc-hing lug F which is shown in Figs; l to l0 as .hexagonal in shape, but this locking lug may be ofany cross section, i'or instance or the elliptical cross section shown `in F ig. 12.
The transverse thickness orp the locking arrangement is such that vthe coacting parts can be placed in the normal clearance space between the two sashes as they slide up or down.
The operation of the device as illustrated in Lligs. l to l0 is as follows Suppose the two sashes to be in the position assumed when the window is closed, which is the position shown in Figs. l and 2; now it will be obvious that the coacting locking members are then entirely apart and do not interfere in any way with the normal closing tight of the window. -Now ii the lower sash be raised, as inthe ordinary way, the locking lugs F on opposite `sides of the lowersash will strike the cam faces (Z2 on the two trip platesk D and D', and the pendulum locks will be swung to the outward position, as indicated to the right of Fig. 9. is soon as the lugs ll" pass the corresponding hooks cl3, the pendulum will` swing back against the rib Z5 and a slight downward movement oi' the lower sash will lock the two together. By pulling down the lower sash, the two sashes may be moved to the desired position with an air opening above the upper sash and below the lower sash. 4
lf it' is desired to make` the air opening through the window still larger, the lower sash is shoved still higher, when the in- 'lhe projection D* isprovided with a we( gri-shaped lower portion al, hav-y clined ribs di on the upper sash will wedge the lugs F to the outward position again, and the lower sash may be slid ireelypast the upper sash until-the lugs ll" are above the upper edge of the cani `faces dm. At this time the pendulum lugs will tend to swing back to the vertical position, and a slight downward movement of the lower sash will cause the pendulum lugs to swing inwards, as indicated to the left of Fig. 9, and these lugs will pass the hooks 65" and will swing into the pockets all?. At this time an upward movement of the lower sasliwill tend to closethe gap at the top of the two sashes, but will leave a large air space below the lower sash. A
li it is desired to close the window en tirely, push up on-the lower sash until the upper sash has reached its highest position, then pull down the lower sash again and the pendulum locli will automatically swing clear, riding down on the ribs d, pastv the channel D0, and the lower sash may be completely closed.
lf the upper sash is at any time in the desired position, the` lower sash may be closed without disturbing the upper sash by pushing on the saine until the lugs'llV register with the passages D0. At this time these lugs will `swing into said passages, and pulling down on the lower sash will simply permit the lug ll" to pass through said passages without disturbing the upper sash, and the `lower sash may be returned to the closed position.
Thus it will be seen that the lower sash may be moved independently of the upper sash, or'the two sashes may be moved togetheras desired,'without necessitating the operator touching the upper sash at all. rlhis is a great convenience especially with high windows, or short persons.
In the construction of the device shown in 'Figs l to the interlocking parts are shown as mounted on the inside of the window, but to meet the capricious requirements oit the user it may be preferred to mount the same on the outside of the window, in which case the parts would be reversed as vshown in Fig. l0, that is, the trip plates would be attached to the lower sash and the pendulum locli would be attached 'to the upper sash, the parts otherwise being the same as already described.
`While l have shown two sets oil' interlocking devices mounted, respectively, at opposite sides ol'l the window, it will be obvious that under certain conditions a single set on one side only of the window will sullice; but the parts will be better balanced and rwill operate more satisfactorily if the ydevices are mounted in pairs on opposite sides of the window.
It will be noted that the trip plates shown in detail 1n Figs. 6 and 7 are of the same 'Cil lil.:
straight; and in coaction with such trip plates l provide the locking pendulum of the form shown in Fig. l2, in which the locking pendulum F2 is provided with elliptical lugs F ln Figs. ll and l2 l have shown only one of the trip plates and corresponding locking pendulums. The other plates and pendulunis would be obviously reversely disposed.
The device constructed in this way will .operate somewhat more smoothly than if the locking lugs were angular in cross section as shown in F ig. 9.
Viith the arrangement shown in Figs. ll and l2 the parts may be assembled and will operate in the same way as the similar parts shown in Figs. l to l0.
ldhile I have shown the invention in its preferred form or forms, it will be obvious that various modifications might be made in the construction, combination and arrangement of parts which could be used without departing from the spirit of my invention; and I do not mean to limit the invention to such details except as particularly pointed out in the claims.
Having thus described my invention what l claim and desire to secure by Letters lPatent of the United States is:
