L0 CK Filed Sept. 22, 1939 2 Sheets-Sheet 2 Inventor F TILLMAN BROWNNE,
Patented Oct. 8, 1940 I UNITED STATES PATENT OFFICE 3 Claims.
This invention relates to a lock, the general object of the invention being to provide a lock which will tightly close a door or other member when the handle is turned, thus rendering it unnecessary to slam the door.
Another object of the invention is to so construct and arrange the parts that after the parts have been moved to latching position the door can only be opened by raising the handle so that accidental pushing or falling against the handle only serves to close the door more tightly and thus eliminating the danger of accidental opening of the door, this latter feature being desirable especially when the lock is used. in motor vehicles or other moving vehicles.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.
In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which: v
Figure 1 is a fragmentary vertical sectional View through a portion of a door and its frame, the section being taken on the line Il of Figure 2.
Figure 2 is a section on the line 2-2 of Figure 1.
Figure 3 is a view similar to Figure 2 but showing the case in section and the parts in the case in elevation or plan.
Figure 4 is a section on the line 4-4 of Figure 3.
Figure 5 is a vview looking into the look from the front edge thereof.
ure 5.
Figure 7 is a section on the line 1-1 of Figure 4.
In these drawings the numeral i indicates the lock case which is adapted to be placed in a re- Figure 6 is a section on the line 6-5 of Figto its rounded free end. A partition 4 extends horizontally in the case and the latch member 5 is placed above the partition and the pivot B of this latch member passes through the partition. This latch member 5 is provided with a 5 substantially semi-circular portion, the flat part of which roughly lies in the plane which intersects the pivot 6 and on the opposite side of the pivot is a cam part 5 which includes an arcuate edge and a substantially straight edge which 10 forms with a part of the straight edge of the semi-circular portion a notch I for receiving the keeper lug 3. The other portion of the straight edge forming a wedge engaging part 8 which is opposite the notch I. A substantially hook- 15 shaped spring 9 has its shank attached to a bracket ill on the partition 4 and the bent part of this spring engages an eccentric pin H extending upwardly from the member 5 and this spring and pin act to hold member 5 in open position or with the straight edge of the part 5 in position to strike the keeper member 3 when the door closes. As this takes place the keeper member engaging the straight edge of the part 5' causes rotary movement of the latch member 5 25 and the pin ll slides along the curved part of .the spring 9 forcing said spring part inwardly or toward the shank until finally the spring acts on the pin II to cause acceleration of the retary movement of the member 5 under the ac- 30 tion of the keeper member 3 until the adjacent end of the semi-circular part of the'r'nember 5 engages the keeper member as shown in Figures 2 and 3 with pressure to hold the door closed.
A transverse shaft l2 passes through the door 35 and through the casing and is supported for rocking movement and has a handle l3 attached to each end thereof,.these handles being spaced from the door one on one side and one on the other and said shaft has a cam l4 thereon which 40 is engaged by a spring l5 which tends to hold the shaft I2 in the position shown in Figures 2 and 3. A sector-shapedmember l6 of platelike form is pivoted at its corner on the shaft i2 and a portion of the arcuate edge of this mem- 45 her is formed with a wedge I! which gradually increases in thickness from the top edge of the arcuate part to the lower end of the wedge shaped part as shown in Figures 4 and 5. A spring It has one end connected to a pin IS on 50 the member l6 and its other end to a part 20 on the partition, this spring tending to move the member l6 upwardly. The partition is formed with a slot 2| through which the member I 6 passes and the spring I8 tends to move the mem- 55 ber II upwardly through the slot and to cause the small end of the wedge i1 to engage the straight edge I of the member I and as the member ll moves upwardly the wedge will act to force the member I into latching position and the wedging actionso that the member I pressing against the keeper member. 3 will tightly hold the door in shut position and against the lamb strip S of the frame as shown in Figure 2. An
arm 22 is connected with the shaft l2 and extends downwardly therefrom and this arm has limited movement between the stop lug 23 on 1 vent movement of the parts so that the door is held in locking position and cannot be opened until the pin 26 is pulled outwardly. A spring detent 21 for engaging notches 28 in the pin 28 serves to hold the pin inoperative or inoperative position as shown in Figure 7.
When the door is in open position the member 5 is in a position with the part 5 projecting from the edge of the door and the front end of the semi-circular portion located in the casing or approximately so. In this position of the latch member the upper edge of the sector-shaped member I6 is engaging the under face of the latch member as, ofcourse, that portion of the latch member extends across the front end of the slot 2| in the partition 4. Then when the door is closed the keeper member 3 will engage the straight edge of the part 5' which causes rotary movement of the latch member which moves the position of the pin ll relative to the curved end of the spring 9 for as before stated this spring I and pin l I act to hold the latch member in open position but when the latch is rotating due to engagement of the part 5' with the keeper member 3 and after the latch member reaches a position about half way between open and closed position, the pressure of the spring I on-the pin II will assist the rotary movement of the latch member to closed position. After the parts approach a closed position or that shown in Figure 3, the
spring II will cause the member l6 to rotate on the shaft l2 so that the small end of the wedge will move between the wall of the opening 2| and the straight edge I of the latch member I which tends to further close the door and-latch the same even though the door has not been tightly closed and all this takes place withoutmovement of the handles. Then by turning one of the handles downwardly the shaft I2 is partly rotated which causes the arm 22 to engage the stop lug 24 to raise the member I 6 which causes the wedge I! to exert a wedging action on the straight edg 8 of the latch member I so that the pressure of the latch member against the keeper member 3 will tightly close the door against its lamb parts. As will be seen in order to open the door the handle member l3 must be lifted so that there is no danger of the door being accidentally opened by pressure upon the handle or one falling against the same so this device is well adapted for moving vehicles. When it is desired to keep the door from being unlocked from the exterior the pin 28 is pushed inwardly so that it will hold the that such changes fall within the of the partsinthepositionshowninl'igfifiiwiththe door latched. Any suitable locking means may be provided for locking the parts inlatching position from the of the building or structure more the member II rises the greater will be the a It is thought from the forced description that the advantages and novel features of the invention will be readily apparent.
It is tobe understood that changes may be madein the construction and in the combination and arrangement of the several appended claims.
Having described the invention, what is claimed as new is:
1. A latch device of the class described comprising a casing, a latch member pivoted in the casing and including a substantially circular part having a notch in a portion thereof and a straight edge opposite the notch, spring means for normally holding the latch member in position where one of the walls of the notch will engage a keeper member to impart rotary movement to the latch member to cause a corner at the other wall of v the notch to engage a keeper member to latch the parts in closed position, opening movement of the door moving the latch member to releasing position, a manually operated shaft passing through the casing, a plate rotatably arranged on the shaft, wedge means carried by the plate for engaging the straight edge for tightly closing the door by engagement of the latch member with the keeper member, spring means connected with the plate for causing the wedge means to engage the straight edge when the latch member moves to closing position, a pair of spaced projections on the plate and an arm fastened to the shaft and extending between said projections for moving the plate in'opposite directions as the shaft is turned in one direction or the other.
2. A door latch of the class described comprising a casing, a substantially semi-circular member pivoted in the casing and having a notch therein and a straight edge opposite the notch, spring means for holding the latch member in either open or closed position, a shaft journaled in the casing, handles at the ends of the shaft, a sector-shaped member pivoted on the shaft and having a wedge-shaped part on its arcuate edge for engaging the straight edge, the casing having an abutment therein between which and the straight edge the wedge operates, spring means tending to move the sector-shaped member upwardly and cause its wedge to engage the straight edge, the upper edge of the sector-shaped mem ber engaging the lower face of the latch member when the same is in open position, stop lugs on the sector-shaped member, an arm fastened to the shaft depending therefrom and extending between the stop lugs for imparting movement to the sector-shaped member when the shaft is turned in either direction.
3. A door latch of the class described comprising a casing, a substantially semi-circular member pivoted in the casing and having a notch therein and a straight edge opposite the notch, spring means for holding the latch member in either open or closed position, a shaft journaled in the casing, handles at the ends of the shaft, a sector-shaped member pivoted on the shaft and having a wedge-shaped part on its arcuate edge for engaging the straight edge, the casing having an abutment therein between which and the straight edge the wedge operates, spring means tending to move the sector-shaped member upwardly and cause its wedge to engage the straight sector-shaped member with the latch member in closed position from the inside of the door, said means including an arcuate slot in the sectorshaped member, a pin slidably arranged in the casing and passing through the inner face of the door engaging the slot when the pin is pushed inwardly.
