REYERSIBLE LATCH Filed April 22, 1929 swwglg #y Patented Jan. 28, V1934i UNITE-D STA-'rcs ANDREW' EKMAN, 0F GRAND RAIIDS, MICHIGAN, ASSIGNOR TO GRAND RAPIDS COMPANY, OF GRAND RAPIDS, MICHIGAN PATENT OFFICE-c:
BRASS REVERSIBLE lJ LATCH Appncaun flied April 22,
The main object of this invention is to provide a reversible latch having few parts, these parts being simple and economical to produce and easily assembled.
A further object is to provide a reversible latch well adapted for use on heavy doors.
Objects pertaining to details and economies of my invention will `denitely appear from the description to follow. The invention is deiined in the claims.
A structure which embodies the features of my invention is clearly illustrated in the accompanying drawing, in which:
Fig. 1 is an inverted view of my improved latch with the base plate omitted.
Fig. 2 is a detail view mainly in longitudinal section on line 2 2 of Figs. 1 and 3.
Fig. 3 is a fragmentary view on a line corresponding to line 3 3 of Fig. 2.
Referring to the drawing, the housing 1 of the embodiment illustrated is a stamping having an opening 2 in its rear wall and an opening 3 in its front wall through which the bolt 4 projects and is adapted to swing. The base plate 5 is housed within or covered by this housing.
Thepivot 6 is supported at its upper end by the inturned arm 7 formed by strikingin a portion of the rear wall to form the opening 2. The bolt 4: is mounted on this pivot with its front end projecting through the opening 3. The frontend is provided with a strike or keeper engaging roller 8.
The bolt is longitudinally slotted or recessed at 9 to receive the spring 10 and the inwardly projecting arm 11 of the reciprocating toggle member 12. This toggle member has a longitudinal slot 13 engaging the pivot. The spring is disposed between the pivot and the arm 11 under compression.
The rocking or pivoted toggle member 14 is pivoted at 15 on the reciprocating toggle member 12 and has spaced fulcrum points 16 rockingly engaging the front wall of the housing above the opening 3 therein, the front wall of the housing constituting asupporting abutment for the'toggle. f 'Y The side walls 17 of the housing limit the lateral movement yof the pivoted toggle member so that when the bolt is swung on its piv# i929. serial 110.357,07.
ot, the pivot`15 of the pivoted toggle member swings with the bolt, thereby rocking the pivf oted toggle member on one of itslfulcrum points and subjecting the spring l0 to still furtherlcompression, so that when the bolt is released itis again returned to its central position with both fulcrum points of the toggle member bearing against thefront wall of the housing. j y t The structure is very simple and economical in its parts, they partsfare strong and durablel and easily'assembled.
`r Having thus described my invention whaty I lclaim as new and ydeslre to secure by Letters Patent is: Y v
1; In a reversible latch, the combination with a housing, a pivot within'said housing, a longitudinally slotted bolt'mounted on said i pivot, a reciprocating toggle member slotted to embrace said pivot and provided with an.
arm projecting rinto said slotin said bolt` a toggle Ymember pivotally mounted on saidreciprocating toggle member and provided with a pair rof spaced fulcrum points rockingly engaging the front wall of the housing,
the side walls of the housing constituting supports'for the end of said pivoted toggle member, and a spring disposed rinsaidfslot in said bolt between said yreciprocating toggle member and said pivot.
2. In aV reversible latch, the combination withk a housing, a pivot within said housing,V
a longitudinally slotted bolt mounted on said pivot, a reciprocating toggle member slotted to embrace said pivot and provided with an arm projecting into said slot in said bolt, a toggle member pivotally mounted on said reciprocating toggle member and provided with a pair of spaced fulcrum points, and a spring disposed in said slot in said bolt between saidreciprocating toggle member and said pivot.
3. In a reversible latch, the combination with a housing, a bolt pivotally mounted within said housing for swingingmovement, a reciprocating toggle member engaged with said bolt to swing therewith, a second toggle member pivotally mounted on said reciprocating toggle member and provided with spaced fulcrum points rockingly engaging the front wall of said housing,the side walk of the housing constituting supports limiting the lateral movement of said pivoted toggle member, and a spring acting on said reciprocating toggle member to yieldingly hold both fulcrum points of the pivoted toggle member in engagement with their supporting abutments.
4. In a reversible latch, the combination with a housing, a bolt pivotally mounted within said housing for swinging movement, a reciprocating toggle member engaged with said bolt to swing therewith, a second toggle member pivotally mounted on said reciprocating toggle member and provided with spaced fulcrum points, and a spring acting on said reciprocating toggle member to yield* ingly hold both fulcrum points of the pivoted toggle member in engagement With their supporting abutments.
5. In a reversible latch, the combination of a support provided with a pivot, a bolt mounted on said pivot, a reciprocating toggle member slotted to engage said pivot and having slidinr engagement with said bolt, a. second toggle member pivotally mounted on said reciprocating toggle member and provided with a air of spaced fulcrum points, said support eing provided with coacting supporting abutments, and a spring acting on said reciprocating toggle member to urge said pivoted toggle member against its supporting abutments.
6. In a reversible latch, the combination of a support, a bolt mounted on said suport for swinging movement, a reciprocatmg toggle member having sliding engagement with said bolt, a second toggle member pivotally mounted on said reciprocating toggle member and provided with a pair of spaced fulcrum points, said support being provided with coacting supporting abutments, and a sprino' actingv on said reciprocating toggle mem r to urge said pivoted toggle member against its supporting abutments.
In witness whereof I have hereunto set my hand.
