mum number of parts, and with a minimum amount of manual manipulation. Inone form of our invention, we use a rotary bolt, and in a further modification. we use aconventional bolt of the sliding type. While the sliding type of bolt 'is' conventional in that More particularly, the invention; relates to a lock of the class described in which certain operations may be obtained with a'miniof the sliding type of latch bolt againstretraction to open the door, except when certain means are operated from either the outside or the inside of the door, and when'the door is slammed shut. As an important feature of our invention, we arrange for the dogging of the outside operated means, which in this case is a push button, by the inside operated means, which in this case is a lever. Moreover, the same lever that dogs the outside push button against operation, itself releases the latch bolt for retraction when operated in a particular manner.

As a further feature of our invention, we arrange for the releasing of the dogging of the outside operated button when the door is slammed shut, should the button be dogged'with the door in open position. As still a further feature of the invention, it is possible to assemble the lock relatively to the door and the usual sliding glass window, without the employment of relatively costly mechanism heretofore required for avoiding obstructing the window operation; All of this will be clear to those skilled in the art.

More in detail, the sliding bolt modification of our invention comprises a bolt which isspring projected into locking position, this bolt cooperating with a strike whereby it latches back and forth until it reaches a locking position. The

strike and bolt are so designed that a reverse pressure on the bolt by the strike is adapted to retract the latch so that the door may be opened.

' For preventing the retraction of thelatch in this manner, we use a dogging membenwhich in our preferred embodiment is a slide member, and this slide may be retracted from dogging pos tion by an inside operated lever, or by an outside operated lever. The inside operated lever, moreover, may dog the outside operated lever.

. latchback, we utilize a very unique and novel mechanism-for moving the dog ng slide out or dogging relation 'to the boltas the door is swung that. This mechanism, in apreferredform, comprisesfan auxiliary bolt member which is ro- .tatablyj,,mounted, preferably 'on the bolt itself, an'dwhichj impinges asamstthe strike in ad varice'of 'thebolt, Whenso' impinging, it rotates v and n'lovesthe slide-vertically and out o.f dog'-. m retractive movement of the bolt itself which fol-- 'lo'wsimmediately'thereafteni Because of the natureof our construction, we"

'ging relation to the boltiust in advance of the areableto use an L shapedbase plate 'for our lock, comprisingabaseplate member and an end 'platemember. The mounting of the outside operated levris such on the end plate that'the glass may come into juxtaposition to the endi "plate without interfering with the operation of the lock. f 1

In the second modification of our invention, we utilize a rotating bolt which is" dogged against rotation in an unlocking direction by a slide, very similar to the slide in the first modification. Because of the nature of the bolt, the bolt itself retracts the slide in a latching manner toallow the bolt to move into locked relation to the strike. Reverse rotation of the-bolt, however, is prevented by the slide member, and toallow this reverse rotation, it is necessary to retract the slide member by the inside or the outside lever,

much as in the first modification.

Of course, the inside and outside levers control one another as in the first modification. We utilize the latching back or retracting of the sliding dog member by the latch bolt as it moves into locked relation to the strike to release the outside lever from the inside lever, much as in the first modification; We have. thus described the two modifications of our invention generally, because we believe that this general description will be helpful in a proper appreciation of the detailed structure which follows.

In describing our invention in detail, we shall. refer-- to the 'drawingswherein Fig. 1 is an elevation showing our rotary bolt lock. and its relation to the operating structure. Figs. 2 and 3 are sections taken along lines 22 and 3-3 of Fig. 1.

Fig. 2a is a section taken alonglines 2w2a of Fig. 2. Fig. 4 is a view'of certain parts of Fig.

1 in a second position. Fig. 5 is a section taken along lines 5 5 of Fig. 4. Fig. 6 is a perspective .view of our entire lock assembly. Fig. 7 is a view similar to Fig. 1 of the sliding bolt lock of our invention, while Fig. 8 is a section along lines 8- 8 of Fig. '7. Fig. ,9 is a section along lines 9--9 of Fig. 7. Fig. 10 is a section along lines iii-i0 of Fig. 7. Fig. 11 is a view of certain parts of Fig. '7 in a slightly different position.

the particular structure.

For convenience, we shall first describe the sliding bolt lock of our invention. Referring now to Figs. 7-12, inclusive, and especially to Figs. 7 and 12, the frame of our lock is an L shaped member having a base plate portion l0, and an end plate portion ll. ofa nose l2 riveted at l3 to a tail H, the tail extending at I5 into a bearing member l6 carried on the base plate |0.- The nose of the bolt extends through an opening H in the end plate II, this opening l1 and the bearing l6 acting as guides for the bolt assembly. A coil spring l8 projects the bolt outwardly from the lock, this projection being limited-by a lug IS on the bolt tail |4 cooperating with a rubber lug 20. In Fig. 12, for convenience, thebase and end plates l0 and II respectively are not shown, nor is the tail of the bolt, only the nose l2 and the rivets l3 being illustrated.

For locking the bolt |2 against retraction, I

employ a dogging slide 2| cut away at 22 for support on a pair of studs 23 and 24 extending from the base plate M. A spring 25 presses on the surface 26 of the slide 2|, and maintains it in its position of Figs. '7 and 12 in dogging relation to the bolt l2, with .its portion 2 la behind the shoulder |2a of the bolt.

An inside operated lever 21 is pivoted at 28 to the base plate I0, and has a portion 29 impinging against 9. lug 30 struck from the slide 2!. When the lever 21 rotates in a.counterclockwise direction in Figs. 7 and 12, it moves the dogging slide 2| out of dogging relation to the bolt l2. A

spring 3| cooperates with either one of two depressions 32 of a plate 33 forming part of the lever 21 for yieldingly holding the lever 21 in its position of Figs. 7 and 12, or in the positionof Fig. 11 clockwise from its position of Figs. 7 and 12, in which position it performs a further function, to be described presently.

The end plate II has pivoted thereto at 35 a lever 36 which has an arm 31 adapted to be contacted and operated by a push button, to be described presently, which push button is mounted on the outside of the door, and which rotates the lever 36 about its mounting 35. The arm 38 of the lever 36 is adapted through contact at point 33 with the slide 2|, to move the dogging slide out of dogging position in the same manner as it is moved by inside lever 21.

' The lever 36' has a further arm 40, and it is through this arm 40 that the lever 36 is dogged against operation by the arm 4| of the lever 21. Thus, when the lever 21 is rotated in a clockwise direction from its positions of Figs. 'I and 12, the arm 4| thereof moves in behind the arm 40, as shown in Fig. 11, and blocks rotation of the lever 36 intended to move the dogging slide 2| out of dogging position.

Because of this relation of the-parts, the lever 21 may rotate in one direction about pivot 28 to retract the slide 2|, and may rotate in another direction to block the operation of the outside lever 36 so as to prevent release of the locking mechanism from the outside ofthe car, thus contributing a form of protection which is valuable in this type of lock.

Glancing now at Fig. 12, it that the bolt I2 is dogged against retractive movement, and were the door slammed into shut position with no means present for retracting the dogging slide 2|, the door could not be shut except by operation limultaneomly of one of. the

The bolt isformed will be appreciated Fig. 12 is a perspective view of essential parts of levers 21 or 36. To allow the door to be slammed shut without operation of either the inside or outside levers, we utilize an auxiliary bolt 42 which is preferably pivoted at 43 on the bolt l2, and which has a tail 44 impinging against a cam piece 45 stamped out of the dogging slide 2|. This auxiliary bolt 42 is adapted to contact the strike with which the bolt l2 cooperates, in advance of the bolt l2, as is probably best illustrated in Figs. 8 and 10. In Fig. 8, the strike is designated by reference numeral 46, and has two locking portions 41 and 48, so as to give a double locking action which is deemed necessary in the art.

As the door is swung shut, the auxiliary bolt 42 first impinges against the strike and moves on its pivot 43, acting through its tail 44 and cam 45 to move the slide 2| upwardly and out of deadlocking relation to the bolt |2. This movement is repeated for the second locking at 48, as will,

be understood, thus bringing'the parts to the locking position illustrated in Fig. 8, all as is quite apparent.

We have found it desirable to provide means for releasing the outside lever 36, should that lever be locked against movement when the door is open, and the door then slammed shut. This is to prevent a locking out of the owner of the car. In order to describe this action, let us assume that the lever 21 has been rotated about its pivot 28 to bring its portion 4| in obstructing relation to the arm 40 of the lever 36, that is, to the position of Fig. 11. This, it will be noted, brings a cam piece 49 of lever 21 in rather close relation to a surface 50 on the bolt tail l4, all as is shown in Fig. 11.

Now, should the door be slammed and the auxiliary bolt 42 perform the function of moving the slide 2| out of dogging relation to the main bolt l2, the retractive movement of the main bolt will through cobperation ofthe surfaces 48 and 50, rotate the lever 21 back to its position of Figs. 7 and 12, or out of locking relation to the arm 40 of lever 36. This, of course, releases the lever 36 for operation from the outside, all as will i be clear.

For rotating the lever 21, about its pivot 28, we may use a standard type of remote control mechanism, although any other type of mechanism is For convenience, we have shown a rotating lever 5| connected through arm 52 and lever 53 to the lever. 21, it being obvious that rotationof the lever 5| by a suitable handle against the pressure of 'a'control spring 54 will serve to rotate the lever 21 either into a position to retract the dogging slide 2| from dogging position, or to rotate the lever 21 into position dogging the outside release mechanism against operation.

For rotating the lever 36 on its pivot 35 to move the dogging slide 2| out of dogging relation to'bolt l2, we utilize a push button 55, or a cylinder lock '55, as the case may be. In three doors of a four door sedan, we use a push button, but in the fourth door, we use a cylinder lock. In principle, this follows thepractice in the automobile industry today. As is illustrated in Fig. 8, the cylinder lock 55 is locked from the outside by therotation of a cam 56 thereon which interlocks at.56a with a sleeve 51 forming part'of the outer surface 58 of the door. This maintains the cylinder 55 against inward sliding movement necessary to operate'lever 36. When the cam part 56 is out of the notch 56a of the sleeve 51, the cylinder 55 may slide inwardly in Figs. 8

and 9 and rotate the lever 36, all as is quite apparent. In the case of the push button used on three of the doors, it will be possible always to apply pressure to the lever 36, but it will be impossible to rotate the lever 36 when it is locked by the arm ll of lever 21 from the inside.

We have now described the operation of bolt l2 and its locking by the slide 2|. We shall now describe how the bolt I2 is retracted from its locked position of .Fig. 8-to permit the opening of the door. Granted that in Fig. 8 the dogging slide 2! is'moved to releasethe bolt l2, it is necessary to 'understand how the bolt is retracted.

the bolt 62 and itspart 65 rotate in a locking direction, it being obvious that the slide will move up and downuntil, when the bolt is in the position of Fig. 2, theparts will assume the position of- Fig. 6. As was explained previously, reverse rotation of bolt-62 is of course prevented with theparts in the position of Fig. 6.-

If the door is open and the lever H is moved into position to lock the lever 36 against rota- Examination of bolt l2 will illustrate that it is I beveled-on both sides in such a manner that it will cooperate with the strike surfaces 41 and 48 in a manner to force the bolt l2 rearwardly against the pressure of its spring l6 when a pull is exerted on the outside handle 59, or when pressureis exerted against the door from the inside in the direction of the arrow 66' in Fig. .8. The,

operation from the outside will be as follows:

tion to retract the do ng slide 10 (Figs. 4 and '5), should the doo'rbe slammed shut,- the following action will take place: The bolt 02 [3nd its part 65 will be rotated into locking rela ion to the strike, and during this rotation will move ,the slide 10 upwardly against its spring .25, as

' was already described. This upward movement Should the ;1ever 36 not be dogged from the inside by an occupant of the car, pressurev on" push buttonorlock cylinder 55 from the outside rotate thelever 36, causing-it tomove dogging slide 2| out of dogging position. A-pull on the, handle 59 will now. cam the bolt l2 back, opening all ofwhich will of course be apparent to those who have studied the particular problem, and

who know of the, many costly mechanisms which have been developed to make possible a narrow window frame.

Weshall now refer to Figs. 1 6, inclusive, wherein we show a form of our invention in which we utilize a rotary latch bolt 62 formed with four teeth 63, and mountedfor rotation on end plate II on the axis of a shaft 66. The shape of the bolt 62 and its teeth 63 is probably best illustrated in Fig; 2a. Secured on the shaft 64 for rotation. therewith simultaneously with bolt 62 is member 65 having teeth 66 shaped similarly, but

not exactly like teeth 63 of bolt 62.

In Figs. 2a and 3, there is shown at 6'! a strike having portions 68 adapted to interlockwith the teeth 63 of the bolt 62. The operation of bolt 62 and the member 65 is such that the two parts 62 and 65 may rotate freely in a.direction to interlock the bolt and strike, that is, to the position of Fig. 2. A reverse rotation of the bolt 62 and its part 65 is prevented by a lug 69 on a dogging slide 70, which is similar todogging slide 2! in most particulars. mounted on thebase plate I0, is similarly spring pressed in a locking direction, and is similarly retracted out of dogging position through a lever 'H, which is almost identical with lever 2! of my first modification.

The lever Ii acts to lock a lever 36 against operation from the outside exactly the same way as in the first modification described (Figs. 4 and 5). The lever 36 in turn retracts the dogging slide 10 in the same manner as in the first modification through the use of arm 38. For throwing oi! the locking of the lever 36 by the lever '|l,'we'.utilize Thus, the slide 16 is similarly F s. 4 and 5 ,ouite apparent,- e I V The lever' ll is-controlled much: in the same manner'as is the lever 21 of the first modificawill cause the uppersurface 12 of the lug 63 to abut the under surface .13 of the arm ll of lever.

Ii, moving the lever from its locking-positions of into its position of Fi 6, all as is tion, thatis, by a remote control handle 15, illustrated in Fig. 1. Rotation of the handle I5 into the position marked deadlocked, wfll, through 1 suitable means rotate the lever II into its dot and dash line position of Fig. 1, in which position the outside operated lever 36 will'be locked againstoperation. If, on the other hand, the handle 15 is rotated into unlocking position, 'the slide."

will be moved vertically from the position of Fig. 6, releasing the member 65 for rotation. This, of course, releases the bolt 62 for rotation to release position.

The outside operated lever first modification. When the push button 55 operates lever 36, a pull on the handle 59, which is exactly like the handle of the first modification, causes a rotation of the bolt 62, allowing the a construction which is but slightly different in detail from that of the first modification. The

door to move to fully open position.

We believe that the operation of our invention will now be quite clear to those skilled in the art.
