Specification of Letters Patent.

Patented Sept. 18, 1906.

Application filed March l2 1906. Serial No. 305,465,

To all whom it may concern.-

Be it known that I, CHARLES J CALEY, a citizen of the United States, residing at New Britain, Hartford county, Connecticut, have invented certain new and useful Improvements in Bolts, of which the following is a full, clear, and exact description.

My invention relates to improvements in bolts; and in the accompanying drawings I have shown it as applied to what is known as a Cremorne bolt, as applied to doors or swinging windows.

As is well known, in windows the sash being comparatively light becomes warped and twisted on drying out, causing much trouble, making it necessary to readjust the keeperplates and otherwise causing much annoyance in keeping said windows effectively closed and tight. To meet these conditions, I have devised simple and effective means whereby the objections are remedied.

In the accompanying drawings, Figure 1 is a front elevation of my invention as it appears in place, one of the finishing-pieces being removed. Fig. 2 is a side elevation partly in section. Fig. 3 is a relatively enlarged view of the bolt end and the adjacent keeper-plate viewed from in front. Fig. 4 is a side elevation of the same, partly in section. Fig. 5 is an elevation of the'bolt-operating means. Fig. 6 is a relatively enlarged detail of construction in elevation. Fig. 7 is a relatively enlarged view of the inner end of one of the bolt-rods.

A A represent bolts, the former bein arranged to lock the lower edge of a win owsash or door, the latter being arranged to B represents an operatinghandle which when turned in one direction projects both of said bolts A A and when turned in an opposite direction retracts the same.

To fully comprehend the nature of the in vention, it is only necessary to describe one of the bolts. To that end it will be seen that the bolt A is provided at its lower or looking extremity with a longitudinal groove or recess C, in which reciprocates a wedge member D, the same being guided by pins E E, carried by the bolt and passing through a slot in the wedge. F is a shank for the wedge D, said shank moving in a recess in the bolt A coiled spring G, the function of which is to normally project the wedge toward the free end of the bolt or into the position shown in Figs. 3 and 4. II is the usual keeper-plate, the bolt-opening therein being, however, considerably larger than the end of the bolt A, so that when said keeper is fitted in place there will still be suflicient clearance for the bolt end to properly enter, even though the door swells or shrinks. As such a construction would permit the door or sash to rattle, in the absence of effective means to prevent it I have provided the wedge member D, above referred to, the size of which is such that when the bolt is projected into the hole in the keeper H the wedge will freely enter, but will finally become tightly engaged with the edges of the bolt-hole therein. The swell of the wedge D is preferably on one side only of a vertical line, so that it will be unnecessary to cut into the door to provide clearance when the bolt is applied thereto.

As will be seen by reference to Figs. 1, 2, and 4, the slot in the wedge in which the guide-pins E E are located is sufficiently long to permit the bolt to enter into the recessin the keeper-plate II to a greater de ree than the wedge member. l/Vhen the we( ge member is checked by engagement with the keeper, any further movement of the bolt will simply cause the spring G to compress. By this arrangement, as before indicated, su'l'licient clearance is provided to avoid readjustment of the keeper-plate when the door or sash swells or shrinks and rattling is absolutely prevented. In the drawin s, the upper bolt A is provided with a simi ar arrangement for locking the upper edge and preventing it from rattling. The handle B is provided at its inner end with a plate I, having two studs J J, which project into transverse grooves K K in the inner ends of the bolts A A, respectively. L is a stop ar ranged to prevent the handle B from being turned-backwardly beyond a positionwhere the studs J J are in vertical alinement.

As shown in Fig. 5, the opposite sides of the ends of the bolts A A are cut away, so that they will clear each other as said bolts are retracted. The turning of the knob in one direction will cause the studs J J to move in the grooves K K, respectively, and will and being springpressedfor example, by a 1 thus retract the bolts. A reverse movement will project the bolts. M is a finishing-plate affording a bearing for theknob B. N is an end plate arranged to cover that end of the bolt adjacent to the upper or lower edge of the door. This plate N is provided with a clearance-recess for the wedge D. In the drawings the lower one of these plates N is omitted. Intermediate guide and finishing platesO 0 may be provided, if desired.

While of course this invention has particular value in connection with a bolt of this type, it need not necessarily be confined thereto. 7

What I claim, and desire to secure by Letters Patent,.is

1. In a bolt, a wedge member carried by the bolt and slidable relatively thereto, and guiding means therefor.

2. In a bolt, a longitudinal groove or recess, a wedge member carried by the bolt and slidable in said groove, guiding means therefor, and a spring normally projecting said geldge member toward the free end of the 3. In a bolt, alongitudinal groove or re cess, a wedge member carried by the bolt and slidable in the groove, and guiding means therefor, in combination with a keeper-plate having a bolt-opening therein of substantially greater diameter than the end of the bolt proper, but of less diameter than the greatest thickness of the bolt plus the wedge member.

4. In a bolt, a longitudinal groove or recess, a wedge member carried by the bolt and slidable in the groove, and guiding means therefor, in combination with a keeper-plate having a bolt-opening furnishing substantially greater clearance than required by the end'of the bolt proper but less than required for the free passage of the boltplus wedge member, and a spring tending to project said wedge outwardly or toward the free end of the bolt.

5. In a bolt, a longitudinal groove or recess therein at the locking end thereof, and a tapered wedge member guided in said groove or recess, the tapered surface of said wedge member standing above the outer surface of the bolt.

6. In a bolt, a longitudinal groove or recess therein at the locking end thereof, a tapered wedge member guided in said groove or recess, the tapered surface of said wedge member standing above the adjacent outer surface of the bolt, a shank carried by said wedge member, and a recess in the bolt arranged to receive said shank.

7. In a bolt, a longitudinal groove or recess therein at the locking end thereof, and a tapered wedge member guided in said groove or recess, the tapered surface of said wedge member standing above the adjacent outer surface of the bolt, a shank carried by said wedge member, a recess in the bolt arranged to receive said shank, and a spring in said recess bearing against said shank and arranged to project the wedge toward the free end of the bolt.

8. In a locking device, two oppositely-arranged bolts, a guide therefor, a rotary operating device carried by said guide, two studs carried by said operating device and oppositely placed relatively to the aXis of rotation thereof, and transversely-extending grooves in the adjacent ends of said bolt members, said studs projecting into said grooves.
