Abstract
Abstract The invention relates to a window latch with a lockable bolt axially slideably mounted in a housing. The locking means for the bolt is a keyless combination lock incorporating rotatable slotted annular locking collars located in the bolt housing and disposed coaxially around the bolt. The bolt in the locked position is received in bolt receiving means, there being a pivotable latch on the bolt receiving means which has a surface having a co-operative relation with a tapered surface on the housing so that when the bolt is in the locked position the latch holds the bolt receiving means and housing securely together.

Claim 1
Independent Claim
317 words
A window latch comprising: housing means; bolt means axially slideably mounted in said housing means; bolt receiver means; an integral keyless combination lock means on the housing means capable of locking said bolt means in a first position in said housing means, in which first position axial sliding motion of the bolt means out of the bolt receiver means is prevented, said integral keyless combination lock means also being capable of allowing said bolt means to be withdrawn to a second position in which said bolt means is withdrawn from said bolt receiver means; pivotable lever arm means provided on the bolt receiver means and having a surface for engagement with a complementary surface of the housing means to releasably hold the housing means and bolt receiving means together when said bolt means is in said first position; said integral keyless combination lock means comprising a plurality of collars disposed coaxially with said bolt means and mounted in said housing means, said bolt means also comprising lug means protruding from the surface thereof, and said plurality of rotatable collar means each including surface slot means, said lugs each being adapted for engagement with one of said plurality of rotatably collar means in said first position, whereby to move said bolt means axially from said first position to said second position said rotatable collar means are rotated so that said slot means are in alignment with each other and with said lug means so that the bolt means when engaged in said bolt receiver means in said first position can be withdrawn to said second position; and wherein heads of screw threaded means which secure said housing means and said bolt receiver means to respective ones of a window casement and a window frame are so disposed as to be covered by said bolt receiver means and said housing means in said second position of said bolt means.

A window latch comprising: housing means; bolt means axially slideably mounted in said housing means; bolt receiver means; an integral keyless combination lock means on the housing means capable of locking said bolt means in a first position in said housing means, in which first position axial sliding motion of the bolt means out of the bolt receiver means is prevented, said integral keyless combination lock means also being capable of allowing said bolt means to be withdrawn to a second position in which said bolt means is withdrawn from said bolt receiver means; pivotable lever arm means provided on the bolt receiver means and having a surface for engagement with a complementary surface of the housing means to releasably hold the housing means and bolt receiving means together when said bolt means is in said first position; said integral keyless combination lock means comprising a plurality of collars disposed coaxially with said bolt means and mounted in said housing means, said bolt means also comprising lug means protruding from the surface thereof, and said plurality of rotatable collar means each including surface slot means, said lugs each being adapted for engagement with one of said plurality of rotatably collar means in said first position, whereby to move said bolt means axially from said first position to said second position said rotatable collar means are rotated so that said slot means are in alignment with each other and with said lug means so that the bolt means when engaged in said bolt receiver means in said first position can be withdrawn to said second position; and wherein heads of screw threaded means which secure said housing means and said bolt receiver means to respective ones of a window casement and a window frame are so disposed as to be covered by said bolt receiver means and said housing means in said second position of said bolt means.
Claim 3
Dependent Claim
180 words
A window latch having a sliding bolt, a bolt housing, a bolt receiver and an integral keyless combination lock by means of which the bolt may be locked, in which the heads of the screws which secure the bolt housing and bolt receiver to a window casement and a window frame are so disposed as to be covered by the bolt housing and bolt receiver when in the locked position, in which the bolt may be prevented from axial displacement by means of two or more collars disposed coaxially with the bolt in the bolt housing, the bolt being provided with lugs on its side which are engageable with the collars so as to prevent axial movement of the bolt, slots being provided in part of the collars so that when the slots are aligned with each other and with the lugs the bolt may be moved in an axial direction, and in which a pivotable lever arm is provided on the bolt receiver and is adapted to engage the bolt housing to hold the receiver and bolt housing together.
Claim 4
