S IDING BOLT.

Application filed June 22, 1921. Serial No. 4=79, 632.

This invention relates to sliding bolts for closures and more particularly to a dead bolt which is adapted to be supported in a suitable guide and to be moved into engagement with a guide loop or the like tolock the closure in'any desired position. Such bolts are usually mounted to slide freely in their'supports and trouble has been experienced with the same when mounted at the top or the bottom of a: door, for example, for the reason that they would accidentally fall orslide into looking or unlocking position when such movement was not intended or desired. When such abolt is mounted at the top of a doorv to slide vertically into its keeper or guide loop, it would very often fall from the force of gravity 'to unlocking position. Likewise, when such a bolt was mounted at the bottom of the door, it would be apt to fall accidentally into engagement I with its keeper to lock the door closed.

Moreover,'whether the bolt wasmounted to move vertically or horizontally, sufficient playwithin its mountings has usually been allowed so that the bolt itself often would come in contact with the surface of the door or closure upon which it was mounted to scratch orscar the same. My invention is particularly concerned with overcoming these disadvantages One object of my invention is to provlde a bolt of this character which'shall be so mounted that it will be frictionally held against accidental movementand will at the same time be secured tightly Within its mountings to obviate any objectionable looseness.

Another object of my invention is to provide a suitable mounting for a bolt of this character, so that it will be resiliently or yieldably held against 'looseness or accidental movement, which may be efficient, practical and inexpensive to manufacture.

A further object of my invention is to provide a half-round or: flat-sided bolt so as to bring about a more effective engagement between the bolt and the flexible members which are designed to frictionally engage the same. I y

' To these and other ends the invention consists in the novel features and combinations of parts to 'be hereinafter described and claimed.

In the accompanying drawings;

' Fig. 1 is a'front elevational view of a bolt embodying the principles of my invention suitably mounted in operative position; Flg. 2 is a view partly in section along line 22 of Fig. 1; I

Fig. 3 is a sectional view of Fig. 1; and

along line 3-3 F 'g. 4' is a detail perspective view of one of the guides in which the bolt is mounted.

The preferred embodiment selected to illustrate the-principles" of my iiivention comprises a sliding or reciprocable bolt 9' suitably mounted in a guide 10 upon a door or other suitable closure 1.1 and adapted to be moved into engagement with a similar guide 12mounted upon thedoorc'asing 13. the latter' guide'serving as a keeper, a1

though substantially identical in form with cross-section, as shown more particularly in Fig. 3, and is in this manner provided with the flat side or surface '15, which is of particular importance in combination with certain other features of my invention.

The guides 10 and 12, as shown inFigA,

consist of a base portion 16, which has an intermediate part 17 struck therefrom to i i provide alloop. Thisloop is substantially half-round inshape to correspond with the shape of the bolt in cross-section and is slightly larger than the bolt to permit the latter to move freely therethrough. Upon each side of the loop 17 is left a more or lessnarrow strip of metal which, as shown,

is cut or slit at '18 to' provide the two tongues 19 at each side thereof. As is clearly shown in Figs. 3 and 4, these tongues are bent up slightly from the plane of the base 16 of the guide to frictionally engage the lower flat side of the bolt and resiliently urge the same into contact with the upper wall of the loop.

The metal from which the guides 10 and 12 are made is preferably of such acharacter that when the tongues 19 are formed in this manner, they will be slightly resilient in order that the bolt may befrictionally held 1 against loose play within the loop and yet be readilyreciprocably movable w thin the loop to locking and unlocking positlon.

The friction resulting from the forcing ment or movement either when engaged with both of the members andlQ, as shown in full linesin Fig. ,1, or when engaged with the guide 10' only and withdrawn from the keeper, as shown 'in dotted, lines in this figure. Thetongues 19 are preferably formed upon both sides of the .loop 17, so that when the bolt is withdrawn from the keeper and is held in one only of the guides 10, it will be efieotively retained in position and will notbe' allowed to swing into contact with the surface of the door or closure niember'upon which it is mounted. I The two points of contact'of the tongues 19 upon either side; of the loop 17 will effectively Y maintain the bolt against such swinging mot-ion. It will be apparent, therefore, that .while I have provided an. effective and ellicient means to frictionallyand resiliently retain the bolt within its guides against any looseness or accidental movement, at the same time my improved bolt, together with its supporting guides, will be economical to manufacture, sotliat a practical structure is obtained from the standpoint both of economy and eflici'ency.

' While I have shown and. described a preferred embodiment of my invention, it is to be understood that the saineis not limited thereto in all of its details, but is capable of modifications and variations which lie Within the spiritof the'in vention and within the scopeof thejappended claims.

What I claim is: I

1'. A guide for a movable bolt comprising a base portion, having a guide loop struck up from the intermediate portion thereof whereby a strip of material is left attached to said base portion-along each open side of said loop, each of said strips being divided to provide apair of tongues, said tongues being bent slightly out of the plane at the base portion for the purpose described. 2. A guide member for sliding bolts comprising a base portion, a loopstruck up therefrom to provide a passageway for the bolt between the loop and. base, a portion of the base at each side of said loopbeing bent upwardly transversely of the bolt to I bear tlierea'g'ainst and cut o r slit longitudinally of the bolt to provide in each portion two opposing tongues, substantially as described, I

3. The combination of a sliding bolt of the type described,'and means to retain and guide said bolt, comprising a of aligned guides, each having a base portion, a looped portion secured to said base and transversely;

"guide for said bolt, having a loopedmember thereon through which the bolt passes, and an upwardly projecting pair of opposed transverse tongues struck up 'at each side of said loop member, from the material form; ing the guide member, to bear againstsaid' bolt to retain it inlengagementxwith said loo.

A guide fora movable bolt, comprising abase p'orti-on'and aloop struck up, therefrom to provide a-passagewayfor the bolt between the base and the. loop and apair of oppositely projecting and, transversely entnding resilient tongues formed upon the base portion at at least two. points in the length ofthev bolt to, bear against theunder surface thereof" to urge said bolt upwardly and parallelwith the surface of said base.

6 A guide for a movable bolt, comprising a. baseha'ving a, looped portion thereon through which the bolt passes, and means extending. across the mouths of said looped portion and bearing against the bolt to force the same into contact with said loop throughout the length thereof to frictionallyretain l the bolt in position.

, 7, A guide for a movable bolt, comprising a base portion having a longitudinally disposed loopedportion struck up therefrom,

and a pair of opposed upwardly projecting tongues extending transversely across each mouth of said looped. portion for the purpose described.

8. A guide. for a sliding boltr, comprising a base having portions for resting against a support, a loop through which the bolt passes conne'ctingsaid base portions, and a pair of tongues extending from each of said base portions and slightly bent upwardly out of theplane of said base portionsto bear against and frictionally engage the bolt in two. places to retain the. same in position parallel with" the support upon which said base rests within the loop. 1

9. A guide for a sliding bolt comprising a the bolt passes connectedto said base por-' t on, and means extending across each mouth of said loop adapted to bearagainst the bolt base portion, a looped portion through which pair of transversely extending spring fingers disposed across each open end of said loop, and adapted to engage the flat under surface of said bolt to urge said bolt into contact With the curved inner surface of said loop throughout the length thereof.

11. A guide for a bolt half round in cross section, comprising a base portion having a semi-circular loop portion secured thereto to embrace said bolt, and upwardly springing means disposed across each of the open ends of said loop beneath said bolt to engage the flat under surface thereof at two points in its length'to urge the bolt into contact with the inner surface of said loop, throughout the length thereof, whereby said bolt Will be retained in parallel With the plane of said base While being moved through said loop.
