lll'l lllllilllllll Witnumo DANIEL W. TOWER, OF GRAND RAPIDS, MICHIGAN, ASSIG-NOR TO GRAND RAPIDS BRASS COMPANY, OF GRAND RAPIDS, MICHIGAN.
LATCH.
Specification of Letters Patent.
Patented Feb. 22, 1910.
To all whom it may concern:
Be it known that I, DANIEL W. TOWER, a citizen of the United States, residing at the city of Grand Rapids, county of Kent, State of Michigan, have invented certain new and useful Improvements in Latches, of which the following is a specification.
This invention relates to improvements in latches.
The main objects of this invention are to provide an improved latch which is simple and economical in structure and attractive in appearance, and one which may be mainly formed of sheet metal.
Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.
I accomplish the objects of my invention by the devices and means described in the following specification.
The invention is clearly defined and pointed out in the claims.
A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:
Figure 1 is a detail elevation of a structure embodying the features of my invention, a portion of the latch knob being broken away to show the arrangement of the parts. Fig. 2 is a detail section, taken on a line corresponding to line 22 of Fig. 1. Fig. 3 is a detail section, taken on a line cor responding to line 33 of Fig. 1. Fig. 4: is a sectional view, through the knob stem, taken on a line corresponding to line 55 of Fig. 1, showing the stop. Fig. 5 is a detail section, taken on a line corresponding to line 55 of Fig. 1.
Referring to the drawing, 1 represents a door and 2 a door casing in connection with which a structure embodying the features of my invention is illustrated to show its operative relation.
The latch plate 3 is preferably in the form of a sheet metal stamping, having holes 4 therein to receive the attaching screws 5. The latch bolt 6 is also formed of a sheet metal stamping and is pivotally mounted upon the bearing member 6. This bearing member projects outwardly from the latch plate, the latch plate being provided with an opening 7 in which the bearing member is arranged and secured. The bearing member is also preferably a stamping, shaped like an inverted cup.
The knob or finger piece comprises a barrel-like stem 8 flanged outwardly at its outer end, as at 9, and the end or cap piece 10, which is secured by folding or seaming its edges 11 over the edges of the barrel portion. The inner end of the barrel portion is preferably beaded at 12 and is secured to the latch bolt, the beading being of some assistance in holding the solder or brazing material with which it is secured to the latch bolt, and further adds to the appearance. The knob stem 13 is carried by the base 6, its outer end being arranged through and headed upon the end piece 10. This secures the knob and the latch bolt in position. The spring 14: is connected at its lower end to the latch plate, being preferably arranged through a suitable opening in the inner end of the bearing 6 and its upper end is connected to the knob, being preferably engaged with the springattaching lug 15. This attaching lug is preferably formed integrally with the barrel portion 8 of the knob by turning in a portion thereofsee Fig. 3. The spring is thus secured in a simple and eflective manner and is supported so that the strain thereon is minimized in the operation of the latch. On the latch plate is a stop 16, which is adapted to engage the stop projection or shoulder 17 on the latch bolt for limiting the movement of the latch.
The keeper preferably consists of a base portion 18 and an engaging portion 19, projecting therefrom, the base portion proj ecting from the edge thereof, the base portion having suitable holes therein to receive the attaching screws 20.
I have illustrated and described my improved latch in detail in the form preferred by me on account of its structural simplicity and economy. I am aware that the same can be considerably varied in structural details without departing from my invention, and, as these variations will readily occur to those skilled in the art to which this invention relates, I have not attempted to illustrate or describe them herein.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. In a latch, the combination of the latch plate; a latch bolt; a bearing on said latch plate for said bolt; a knob for said bolt formed of sheet metal comprising a cylindrical barrel portion flared outwardly at its upper end; and having an inwardlyprojecting spring attaching lug formed integrally therewith, and a cap or end piece journaled on said spindle the edges of said end piece being seamed over the edges of the outer end of said barrel. portion; a spindle for said knob mounted on said hearing and arranged through the end piece of said knob; and a coiled spring arranged with one end connected to said bolt bearing, and its other end engaged with said springattaching lug on said knob.
2. In a latch, the combination of the latch plate; a latch bolt; a knob for said bolt formed of sheet metal comprising a cylindrical barrel portion flared outwardly at its upper end, and having an inwardly-projecting spring-attaching lug formed integrally therewith, and a cap or end piece journaled 011 said spindle, the edges of said end piece being seamed over the edges of the outer end of said barrel portion; a spindle for said knob; and a coiled spring arranged about said spindle with one end connected to said latch-plate, and its other end engaged with said spring-attaching lug on said knob.
3. In a latch, the combination of the latch plate; a latch bolt; a knob for said bolt formed of sheet metal and having an in- Wardly-projecting spring-attaching lug formed integrally therewith; a spindle for said knob; and a coiled spring arranged about said spindle with one end connected to said latch plate, and its other end engaged with said spring-attaching lug on said knob.
4. In a latch, the combination of the latch plate; a latch bolt; a bearing on said latch plate for said bolt; a hollow knob or finger piece for said bolt formed of sheet metal having an inwardly-projecting spring-attaching lug formed integrally therewith; a spindle for said knob mounted on said bearing; and a spring arranged within said knob with one end connected to said bolt bearing and its other end engaged with said spring attaching lug on said knob.
5. In a latch, the combination of the latch plate; a latch bolt; a bearing on said latch plate for said bolt; a hollow knob or finger piece for said bolt; a spindle for said knob mounted on said bearing; and a torsion spring arranged within said knob and connected to said bolt bearing with said knob.
6. In a latch, the combination of the latch plate; a latch bolt; a knob or fingerpiece for said bolt having a. barrel portion; a spindle for said knob carried by said latch plate; and a coiled torsion spring arranged within said knob about said spindle with one end connected to said latch plate and its upper end connected with said knob.
In Witness whereof, I have hereunto setmy hand and seal in the presence of two witnesses.
