JACB SUTER, OF JERSEY CITY, NEW JERSEY.

DOOR AND WINDOW CHECK.

To all whom t may concern:

Be it known that I, JACOB SUTER, a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of' New Jersey, have invented a new and Improved Door and Window Check, of which the following is a Jfull, clear, and exact description.

The invention relates to doorchecks, such as shown and described in the Letters Patent of the United States, No. 97 5,805, granted to me November 15, 1910.

The object of the present invention is to provide a new and improved door and window check arranged to permit of securely locking the door or window against opening from the outside by unauthorized persons, and to allow of partly opening the door or either window sash for Ventilating or other purposes.

In order to accomplish the desired result use is made of two arms pivotally connected with the parts ofthe door or window, and pivotal means Vfor pivotally and detachably connecting the said arms with each other at their free ends to allow of det-aching the arms one from the other whenever it is desired to fully open the door or window, or to permit of pivotally connecting the arms with each other to limit the opening of the door or window or for locking the same in closed position.

A practical embodiment of the inventio-n is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a face view of the check as applied to a door, the parts being in position to allow of partly opening the door; Fig. 2 is a cross section of the same on the line 2 2 of Fig. 1; Fig. 3 is a sectional plan view of the same on the line 3-3 of Fig. 1; Fig. 3a is a similar view ofthe same on the line 3a-3a of Fig. 1; Fig. L1 is a reduced plan view of thecheck as applied to the meeting rails of upper and lower sashes, the parts being in position with the sashes closed and ready for partly opening either of the sashes or both; Fig. 5 is a face view of the same and showing in dotted lines the lower sash partly raised; Fig. 6 is a plan view of'the check as applied to a French window, the sashes being shown in section; Fig. 7 is a plan View of the check applied to a door casing and door and showing the Specification of Letters Patent.

arms in horizontalv position instead of in vertical position as disclosed in Fig. 1; Fig. 8 is a front elevation of the same; Fig. 9 is a sectional front elevation of the same; Fig. 10 is a cross section of the same on the line 10H10 of Fig. 8; Fig. 11 is a similar view of the same on the line 11-11 of Fig. 8; and Fig. 12 is a plan view'of the arms at their pivotal connection and showing a modified form of switch.

The door check shown in Figs. 1, 2, 3 and 3a is mounted on hinge plates A and B secured to the jamb C and the door D, respectively, and the hinge plate A is provided with a longitudinally-extending pivot E on which is mounted to swing up or down an arm F, and on the hinge plate B` is arranged a transversely-extending pivot E on which is mounted to swing sidewise an arm G made in two sections G and G2 pivotally connected with each other by a pivot G3 extending longitudinally, the section G being mounted to swing on the pivot E. On the free end of the ar'm`F is arranged a longitudinally-extending pivot H adapted to be engaged by a bearing G4 formed on the free end of the arm section G2 so as to pivotally connect the arm F with the arm 'section G2 to allow of swingingthe door D into a partly open position. When it is desired to swing the door D fully open then the arm G is swung to the right'into the position shown in dotted lines in Fig. 1, to detach the arm G from the arm F by moving the bearing G4 out of engagement with the pivot H. Itl is understood that when the door D is partly opened, as above mentioned, and at the time the parts of the door check are in the position shownV in Figs. 1, 2.J 3 and 3a then the arm F swings upward on its pivot E and the arm section G2V swings upward onto the pivot G3, but when the door D is to be opened to its full extent the arm G is swung to the right, turning at the time on the pivot E. In order to prevent the arm F and the arm section G2 from becoming accidentally detached when the door D is partly opened, as above described, use is made of a lug H extending from the peripheral face of the pivot H and adapted to travel in an annular recess G5 formed in the free end of the arm section G2 concentric with the bearing G4. A notch G6 is formed in the arm section G2 and intersects the bearing G* and the recess G5 forthe passage of the lug H at the time the arms F and G are in vertical position, and the door D is closed to permit of disconnecting the arm G from the arm F as above explained. When the arm G is pivotally connected with the arm vF and the door D is swung open, as above explained, then the lug H moves out of register with the notch G6 and en# gages the recess G5 so that the arm section G2 cannot be disengaged from the pivot H during the time the door is `in partlyopen position. The arm sectiongG2 can also be held against disconnectionfrom the arm F at the time the arms F and G are in vertical position with the door D closed, and for this purpose use is lmade of a retaining arm I provided with a shaft I mounted to turn centrally in the pivot H, and the said shaft I is pressed on by a spring I2 so as to hold the retaining arm I in sufficient frictional contact with the end of the pivot pin H to prevent accidental turning of the said retaining arm I. The operator, however, can turn the retaining arm .I to register with the notch G6 at t-he time'the arms F and G are in vertical position so that the arm G can be swung out of engagement with the arm F, as previously explained, but when the arm I is turned out of register with the notch G6 at the time the arms F and G are in vertical position then the arm G cannot be disconnected from the arm F, until the retaining` arm I is swung back by the operator into register with the notch G6 and the lug H. The face of the arm section G2 at the retaining arm I is preferably provided with an incline G7 for engagement by the said arm I, to permit of locking the arm section G2 firmly to the arm F at the time the arms F and G are in vertical position. lIn order to prevent the arm section G2 from swinging in the wrong direction on the arm section G, use is made of a stop pin J secured to the arm section G and adapted to be engaged by a shoulder Gs formed on the arm section G2 adjacentA the pivot G3, as plainly indicated in Fig. 2. In order to securely lock the arms F and G together to prevent movement of either of them at the time the door` D is closed, use is made of a locking catch K pivoted at K to the front face of the arm F and provided at its free end with a knob K2 adapted to be taken hold of bythe operator to enable the latter to swing the catch K into or out of engagement with a stud K3 held on the front face of the arm section G2, as plainly indicated in the drawings. Normally the catch K is in the posit-ion shown in full lines in Fig. l, to permit of partly or wholly opening the door D, as above explained, but when itI is desired to lock the door D against opening the catch K is swung into engagement with the stud K3, as indicated in dotted lines iu Fig. 1, to pre` vent movement of the arms F and G. As illustrated in Figs. 4 and 5, the check is applied to the meeting rails of the upper and lower sashes D2 and D2 of a window, that is, the hinge plate A is secured to the meeting rail of the upper sash D2 and the hinge plate B is attached to the meeting rail of the lower sash D3, and the'arms F and G are pivoted on the hinge plates A and B to permit of swinging the said arms when it is desired to partly raise either or both sashes D2 or D3. When it is desired to disconnect the arm G from the arm F the arm G is swung forward away from the meeting rail of the upper sash D2 so as to overlie the meeting rail of the lower sash D3 and thus permit full opening and clos`Y ing of the sashes D2 and D3 whenever it is desired to do so. It is understood that the check itself is exactly the same as the one described above in relation to the door casing C and the door D, and further descrip tion of the same is not deemed necessary.

In the modified form shown in Fig. 6, the hinge plates A and B are secured to the adjacent stiles of the window sashes D4 and D5 of a French window, and in this case the arm F is made in two sections F andF2, of which the section F is pivotally connected with the hinge plate A by a vertical pivot E2, and the sections F and F2 are pivotally connected with each other by a vertical pivot F2. The arm G is the same as above described in reference to Figs. lr to 5, that is, is formed vof two sections G and G2 pivotally connected with each other by a vertical pivot G3, the section G being pivot-ally connected by Va transverse pivot E2 with the plate B. The section F2 of the arm F carries a pivot H2 engaging the bearing G4t in the arm section G2, the same as above described in reference to the check shown in Figs. 1 to 5, and the pivot H2 is provided with a lug H3 adapted to pass through the notch G6 in the arm section G2. A retaining arm I4 is also mounted on the pivot H2 the same as the ann I, and this retaining Iarm is adapted to be engaged by a switch L pivoted at L on the arm section G2 and adapted to abut with its free end on shoulders L2, L3 formed on the free end of the arm section G2 on opposite sides of the notch G6. When the parts are in the position shown in Fig. 6, the sash D5 can be swung into a partly open position to the extent of the range of the arms F and G, it being understood that in this case the arm F is made in sections F and F2 to allow the section F2 to pass inside of the sash D4 when swinging the sash D5 into partly open position, as indicated in dotted linesin Fig. 6. By the use of the switch L the check can be used on either side of the window, that is, when it is desired to use the check on the window in 'which the sash D4 is swung open,

it is only necessary to reverse the switch L. It is understood that when the retaining arm I4 is moved into register with the notch G6 then the operator can disconnect the arm G from the arm F in the same manner as above described, but when the arm l4 is in this position and the window sash D is opened then the arm I4 comes in contact with the switch L and is lthen turned automatically into angular relation relative to the lng H3 to prevent the arms F and G from being disconnected.

In the check shown in Figs. 7, 8, 9, 10 and 11, the arms F and G are arranged horizontally and are pivoted on the pivots E and E held on the hinge plates A and B secured to the door jamb C and the door I), the pivot E in this case being arranged vertically while the pivot F/ is disposed transversely. The detail construction of the check is practically the same as above described, with the exception that the locking device for the arms F and G, that is, the locking device in this case is in the form of a wing nut N held on a threaded shank N screwing in the arm F (see Fig. l0), so that the wing nut N can be turned so as to stand with the Wings in alinement with the arm F or crosswise thereof to extend over the arm section G2 of the arm G to hold the arm G against opening. It is evident that this locking device N may be used on the check shown in Fig. 1 instead ot the locking catch K, or the latter may be used instead of the wing nut N on the device shown in Figs. 7 and 8.

Instead of the pivoted switch L use may be made of a pin O engaging apertures (Y, 02 arranged on opposite sides ot' the notch G6 in the arm section G2, as indicated in Fig. 12 to allow the-use ot'r the check on doors swinging in either direction, it being only necessary for the operator to change the pin from the aperture O to the aperture O2 or vice versa, according to the position in which the door is hung at the time.

As shown in Fig. 9, the pivot G3 screws in the section G to permit oi" using the check on doors swinging either from one side or the other. In this case the check can be used on either side as it is only necessary to screw the pivot G3 into the, section G from the other side of the screw hole.
