F. M. EDGAR ET AL DOOR LOCK Filed Jan. l2, 1924 Patented Aug. 25, 1925.
UNITED STATES i i isernia FRANK M. :EDGAR AND' THOMAS P. ARCHER, 0F DETROIT, MICHIGAN', ASSIN TO TERN'STEDT MANUFACTURING COMPANY, OF DETROIT, MICHIGAN, A ORRA- TION 0F MICHIGAN.
DOOR LOCK.
T o all whom/1? may concern:
Be it known that we, FRANK M. EDGAR and THOMAS P. ARCHER, citizens of the United States, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in Door Locks, of which the following is a specification.
This invention relates to an improved form of automobile door lock construction. The object of the present invention is to save material by eliminating the back plate, which, of course, leaves the lock parts eX- posed. Suitable means are'carried by the front plate, however, to guide the moving parts of the lock which are ordinarily guided by the back plate. This makes a cheap lock suitable for cheap body construction suoli as the recently produced coachesf7 Another object of the invention is to provide means for lubricating the sliding surfaces between the bolt and front plate.
A further object is to provide a guide for the lock lever which will prevent rattling of the same. The bolt at times is not projected to its fullest extent and as a result there is a slight play of thel lever and it 1s the purpose of this invention to provide means for frictionally engaging the lever to prevent rattling. In addition, a simple form of saddle is carried by the latch bolt, which is engaged by the lever for retracting the bolt.
In the drawings:
Fig. 1 is an elevation of our improved form of lock. l
Fig. 2 is a section on the line 2--2 of Fig. 1.
Fig. 3 is a section on the line 83 of Fig. l.
Fig. 4 is a section on the line 4-4 of Fig. l. u
Fig. 5 is a section on the line 5-5 of Fig. l. l
Fig. 6 is a detail in perspective of a fragment of the latch bolt, showing the saddle secured thereto.
Fig. 7 is a detail of a modiiied form of the lever guide.
Fig. 8 is a section on the line 8 8 of Fig. l.
The lock comprises the usual form of vfront plate` a and the face plate I); a bolt c is at the front slidably guided by the front plate.
Application filed. January 12, 192e. Serial No. 685,758.
The bolt is well adapted to a lock of this character as the body of the bolt is formed of sheet metal. The rear of the bolt is carried within the guide plate cZ, said guide plate provided with tongues e which are projected through slots in the front plate, and then bent over as shown in Fig. 5 to secure the guide plate to the front plate. The front plate is provided with a. raised bumped-out portion f which acts as a stop for the bolt.
The sheet metal body of the sliding bolt is provided at one side with a struck up portion g which is adapted to be engaged by the coil spring 7L for projecting the bolt. Grooves z' are struck up out of the sheet metal body of the bolt as shown in Fig. l and Fig. 2. These grooves may be packed with hard grease and this grease will spread out between the bolt and front plate and lubr'- cate these surfaces, and thus reduce the friction .resulting from the sliding of the bolt back and forth against the front plate.
Itiveted or welded to the bolt is a saddle c which is provided with the turned-up ear m which is engaged by the lever n, pivoted at 0 to the front plate. This turned-up ear m is curved as shown in Figs. l and 6 so that a minimum amount of frictional resistance is offered when the lever is actuated to retract the bolt.
The spring t forces the bolt and lever to the right as viewed in Fig. l and if the bolt is allowed to be projected to its fullest ertent the lever will abut the stop p of the front plate. The lever is thus held against the stop p by the tension of the coil spring 7i;
and there is no chance for rattling. However, sometimes the bolt is prevented by the keeper socket from being projected to its fullest extent whereby the lever is not forced positively up against the stop p. This leaves a little play in the lever and the same may rattle back and forth between the stop and the saddle. To overcome this tendency for rattling, we have provided the guide plate y carried by the front plate and spaced therefrom with a stamped out rib r, which frictionally engages the lever. There is suiiicient friction between this struck-out rib and the lever so as to prevent ordinary movement of the lever. However, this frictional resistance is such that the lever may be easily moved when pressure is applied to the handle. In Fig. 7 we show a modified forni of construction in Which We secure a leaf spring to the inside of the guide plate g which frictionally engages the lever n to pirevent rattling.
The roll-back s is pivotally supported by the front plate as is also roll back housing t. This roll-back is adapted to engage the lug w carried by the bolt so that a handle from the outside of the door may retract the latch bolt independently of the handle n Which is located in the interior of the body.
By using the two small guide plates g and al, the necessity for a larger back plate is avoided and the lock can be made much cheaper Which is more in keeping With the hardware intended for the modern automobile coach.
What We claim is:
1. In a door lock, the combination of a plate., a bolt slidably supported by the plate, means for projecting the bolt, means for retracting the bolt, and said bolt provided with grooves having closed ends in the face adjacent the plate for the purposeffof car 1ying a lubricant to lub-ricate the contacting faces of the bolt and plate.
2. In a door latch, the combination of a plate, a bolt slidably supported thereon, means for projecting the bolt, means for retracting the bolt, and said bolt provided With grooves having closed ends in the face of the bolt extending` longitudinally thereof and adjacent the plate for the purpose of carrying a lubricant to lubricate the contacting surfaces.
3. In a door latch, the combination of a plate, a bolt having a body formed of sheet metal, means for projecting the bolt, means for retracting the bolt, and said bolt provided With grooves having closed ends stamped in the sheet metal body of the bolt adjacent the plate for the purpose of earlying a lubricant to lubricate the sliding contacting faces of the bolt and plate.
4. In a doorl latch, the combination of a front plate, a bolt slidable across the front plate but largely exposed, a lever pivoted to the front plate. and arranged to engage the exposed portion of the bolt, and a striplike guide plate clamped to the front plate near the top thereof and arranged to guide the lever, and provided with means for bearing against the lever to prevent the same rattling.
5. In a door latch, the combination of a front plate, a bolt slidably supported thereby and having a sheet metal body portion, a separate L shaped saddle secured to the outside of the sheet metal body portion of the bolt and provided With an ear, means for projecting the bolt, a lever pivoted to the front plate and adapted to engage the ear of the said saddle for the purpose of retracting the bolt.
6. lIn adoor latch, the combination of a front plat",.`a bolt slidable across the front plate but largely exposed, a lever pivoted to the front plate and arranged to engage the exposed portion of the bolt, and a striplike guide plate clamped to the front plate near the top thereof and arranged to guide the lever, and provided with a struck-in rib arranged to frictionally engage the lever to prevent rattling.
7. In a door latch, the combination of a front plate, a bolt slidably supported on the front plate but largely exposed, said bolt provided With means for trapping a lubricant on the side of the bolt which engages the front plate.
In testimony whereof We aiiix our signatures.
