(01. 2792-1675) This invention relates to means which are adapted to be actuated by push-pull handles to retract catches of sliding bolt type, which may be’ combined with lock mechanism and which is 5 usable on doors and other hinged structures. One object of this invention is to provide sim-' ple, e?ective, durable, and inexpensive means to retract sliding bolts of the type indicated. Another object of this invention is to provide 10 bolt retracting means which may be combined with lock mechanism of known construction without materially altering the construction of such mechanism. Control means for catches of sliding bolt type, 15 according to this invention, is characterized by a longitudinally slidable actuating bar or rod which is so constructed that when it is moved from a normal position it retracts a slidable bolt which is arranged at right angles to it or it actuates 20 means to retract such a bolt. In one embodiment of this invention the actu ating bar or rod is so formed that when moved longitudinally it rotates a rollback which in turn retracts a slidable catch or bolt. Preferably the 25 said bar or rod is a ?at strip which is twistedv helically and which slidably engages a slot of complementary shape in the boss of the rollback. In a modi?ed construction the bar may be of other suitable cross section or be screw threaded 30 and the tumbler is provided with a complemen Fig. '7 is a detail perspective view of rollback elements formed of sheet' metal. ' Fig. 8 is a perspective view of a rollback com prising elements as shown in Fig. 7 , in assembled position. 5 Fig. 9 is an end view of. a lock having modi?ed actuating means. 1 Fig. 10 is a side view at right angles to Fig. 9, with parts broken away to disclosethe. sliding bolt and parts associated therewith. 10 Fig. 11 is a sectional plan of the parts in Figs. 9 and 10. I In the arrangement illustrated in Figs. 1 to 6, I5 is a sliding bolt which is actuated toward its normal projecting position by a spring I6 in 15 known manner and which is retractable by a partially rotatable rollback II, also in known manner. An actuating rod [9 which is helically twisted at I9a engages a suitably shaped slot I 8 in the 20 boss Ila of the rollback IT. The respective ends of rod H) are pivotally connected to lever handles ‘ 26a, 20'’ by pins 22 each of which is located in a convenient hole 22*‘. There may be a plurality of holes 22a to facilitate ?tting to doors of dif ferent thickness- The upper end of each handle 20a, 20b is supported on a pivot pin 20° which en gages a lug 2|a on a plate 2| which is ?xed to a face of the door D. > The lower part of each handle. 20*‘, 20b is off 30 set at 20°‘ to facilitate access to a keyhole 20e tary hole. In a further modi?ed arrangement part of the ' that is associated with lock mechanism (not bar or rod is inclined or wedge-shaped to co-act shown) which may be of any suitable type. with part of a sliding bolt in such manner that ‘>5 when the said bar or rod is moved longitudinally from its normal position, the bolt is retracted. But in order that this invention may be more readily understood, practical embodiments there of will now be described With reference to the 40 accompanying drawings in which: Fig. 1 is an end elevation showing part of a door having a lock of mortise type ?tted therein, including twisted bar mechanism to actuate a and is adapted to be actuated by inward pres sure so that when it is pushed in the direction of arrow 20X it ?rst moves the bar [9 longitudi nally to rotate the rollback I1 and so retract the 35 bolt [5, and continuation of the pressure opens the door D. The upper part of handle 20b is normally parallel with the door D (or nearly so) and its lower part projects su?iciently to be Fig. 2 is a side View of the parts in Fig- 1. Figs. 3 and 4 are detail views including a spring bolt and retracting means therefor of the type illustrated in Figs. 1 and 2. In Fig. 3 the bolt is in normal projected position while in Fig. 4 it is retracted. Figs. 5 and 6 are detail views showing a roll gripped by a user. This handle is actuated by a pull in the direction of arrow my to move the bar I9 and so actuate the rollback I‘! to retract‘ 45 ' the bolt l5 and then open the door as before described. Each handle may be provided with a rubber or other suitable bu?er such as rubber block 23 to minimize noise and to absorb any jar. It will be apparent that the‘ form of bar I 9 50 may be modi?ed, for example the said bar may be replaced by a twisted rod of square or other back and an actuating bar or rod at right an gles to the positions shown in Figs. 3 and 4 re suitable cross section or a round bar having a screw thread on its exterior, may be used. In _ rollback to retract the lock bolt. r Handle 20a normally projects outwardly obliquely 55 spectively. any such case the hole in the rollback is suitably 55 2,181,458 modi?ed so that the rollback operatively engages the said bar in such manner that when the bar is moved longitudinally from normal position the rollback is partially rotated. The rollback I‘! may be cast or otherwise suit ably formed in one piece or it may comprise a back mounted on the twisted part of said bar, two members arranged to be ?xed to opposite faces of a door, two handles, means to pivotally connect one end of each handle to one of said members, and means to pivotally connect the ends of said bar to respective handles so that plurality of members l'lb, IF and I‘![1 formed of sheet metal as shown in Fig. 7 and ?xed together the free end of each handle'may be actuated in any suitable manner to form a rollback as to partially rotate the rollback. shown in Fig. 8. In the modi?ed arrangement shown in Figs. 9 to 11 the actuating bar or rod is arlongitudinal ly slidable bar 19*‘ on which is a wedge-shaped projection I95’. The said bar extends through a 2. A control means for catches of the sliding 10 bolt type, as claimed in claim 1, in which said reciprocable bar consists of a flat strip of oblong cross section which is twisted through 180 de 15 hole l5a in a bolt l5‘) and its wedge I9!’ opera tively engages a wall 15° thereof. Bolt l5b is slidably arranged in a casing l5d in known man ner and it is normally actuated to operative pro jecting position by a spring 16a. The ends of bar l9a are pivotally connected to lever handles as 20‘, 20g by which the bar is actuated in man ner previously described. Although no lock mech anism has been illustrated in Figs. 9 to 11 it will be apparent that the described arrangement may 25 be combined with such mechanism while retain ing features according to this invention. I claim: 1. Control means for catches of the sliding bolt type comprising a reciprocable bar the me 30 dial part of which is helically twisted through an angle that does not exceed 180 degrees, a roll as a lever to move the said bar longitudinally grees, in combination with a rollback having an aperture the shape of which is complementary to 15 the cross sectional shape of said strip. - 3. Control means for catches of the sliding bolt type comprising a reciprocable bar the me dial part of which is helically twisted, a roll back mounted on the twisted part of said bar, 20 two plates each thereof having apertures through which an end of the said bar is arranged to pro‘ ject, a lug on each said plate, two lever type handles, means to pivotally connect an end of each handle to one of said lugs, means to connect 25 the ends of said bar to respective handles where by either handle may be actuated as a lever to move the said bar longitudinally, the free end of each handle being o?set to facilitate access to a 30 key hole.
