LATCH.
Specification of Letters Patent.
Patented Nov. 6, 1906.
Application filed September '7, 1905. Serial 110.277.283-
To wZZ whom it may concern:
Be it known that I, JOSEPH BROADBELT, a citizen of the United States, residing at Arnolds, in the county of Anne Arundel and State of Maryland, have invented certain new and useful Improvements in'Latches, of which the following is a specification.
My invention relates to improvements in latches for gates and doors, and is particularly designed for use on barn-doors and farm-gates.
The object of the invention is to provide an improved construction of latch that will be certain in its operation even when the door or gate is slammed, as must often be done when the operator has charge of arestive horse that cannot be left unattended.
Another object of the invention is to provide a construction of latch that cannot be readily operated by horses or cattle.
The invention is illustrated in the accompanying drawings, in which Figure 1 illustrates a front elevation of a portion of a door or gate provided with my improved latch. Fig. 2 is an enlarged sectional plan view of the same as would appear on the line 2 2 of Fig. 1. Fig. 3 is a vertical section of the latch in the locked position, the section being taken on the line 3 3 of Fig. 2. Fig. 4 is another vertical section showing the latch in the position for the door or gate to be opened. Fig. 5 illustrates an other vertical section to show the position of the locking-bolt when the door or gate is opened; and Fig. 6 is a sectional view through the keeper, the section being taken on the line 6 6 of Fig. 1.
In the drawings, 1 designates the door or gate, which is hung on hinges 2 and to which my improved latch is applied. A horizontally-extending bar 3 is rigidly secured to the gate or door, and one end 4 of this bar projects beyond the edge of the door and is provided with a horizontal slot 5, which when the door is closed has position in front of the frame 6. A guide 7 is preferably cast integral with the bar 3 and extends in a vertical direction, and said guide is provided with a slot 8. A latch-bar 9 is'pivoted at 10 to one end of the rigid bar 3, and said bar normally extends in a horizontal direction and projects through the slot 8 of the guide. The free end of this latch-bar is turned outwardly at 11 and from said outward turn extends laterally at 12, so as to have a position in front of but spaced from the frame 6, as can be clearly seen in Fig. 2. The extreme outer end of this latch-bar when in the normal horizontal position will lie in aplane just above the slot 5 in the rigid bar 3. A stem 13 extends freely through a hole in the rigid bar 3 and also through the door 1, and each end of said stem is provided with a suitable knob 14, by which the stem may be turned or rotated. Secured to this stem so as to have position just beneath the bottom edge of the latch-bar is a plate 15, which when the knobs and stem are rotated will cause the latch-bar to be moved vertically on its pivot 10.
All of the devices heretofore described are attached to and move with the door or gate.
Secured rigidly to the frame 6 is a casing or housing 16, which is provided with a recess 17 and also has a vertical slot 18 in its outer wall 19. The lower end of the casing recess and slot are open. A horizontal slot 20 is provided in the rear wall 21 of the casingplate, and this latter slot is just beneath the lower end of the vertical slot 18 in the outer wall. A staple 22 is rigidly secured to the casing-plate below the slot 20, and said staple projects outwardly beneath the lower end of recess 17 and vertical slot 18.
Beneath the casing or housing and secured to the frame 6 is a vertically-disposed leafspring 23, whose upper end 24 is turned inwardly and has position at the open end of the casing-recess 17. This free end of the spring projects through the staple 22 and is movable therein.
A bolt 25 has position in the casing-recess 17, and said bolt is provided at one side with a portion in the present instance in the form of a vertical flange or rib 26, which projects through the vertical slot 18 in the front wall of the casing. This projection 26 does not extend to the lower end 27 of the bolt, but terminates at a point above said end.
When the door or gate is closed, the end 12 of the pivoted latch-bar 9 will have position against the bottom edge 28 of the projection 26 on the bolt, and when the latch-bar is operated by turning the knob 14 the bolt will be moved vertically in the recess 17.
It will be noted that the inturned end 24 of the leaf-spring 23 serves to sustain the bolt 25 in the elevated position when the door or gate is open, and when the door or gate is closed this inturned end 24 will pass through the slot in the casing-plate and I enter a recess 29 in the frame 6 at the rear of said casing-plate, as seen in Figs. 2, 3, and 4.
In the operation of the latch, supposing the door or gate to be closed, as in Fig. 1, the turning of the knob 14 will cause the free end 12 of the latch-bar to be elevated and the bolt to be moved'vertically, so that the lower end 27 of the bolt will be withdrawn from the staple 22. When the bolt is thus withdrawn, the door may be swung open, because the slotted end of the bar 8 can pass off from the staple. As this bar 3 moves outwardly the inturned end 24 of the leaf-spring will follow close behind it, so that when the end 12 of the bar disengages from the projection 26 of the bolt the inturned end of the spring will be directly beneath the bolt, and thus sustain it in the elevated position while the door is open, as clearly seen in Fig. 5.
When closing the door or gate, it is unnecessary to turn the knob 14, and the mere slamming of the door to the closed osition will cause the slotted end 4 of the ar 3 to pass over the staple 22 and in passing over said bar to push the inturned end 24 of the leaf-spring from beneath the bolt and into the slot at the rear, and as the slotted end of saidbar 3 passes to the rear of the bolt the latter will drop into staple and hold the door closed.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a latch the combination with a stationary bar on the door, of a pivoted latch bar also on the door; a staple on the frame; a bolt movable through the staple, and a leaf spring at the lower end of the bolt for sustaining the latter in the retracted position while the door is open.
2. In a latch the combination with a slot ted bar on the door, of a latch-bar pivoted at the side of the said slotted bar; a staple on the frame with which the slotted bar en gages; a bolt movable through the staple and in front of the slotted bar and a movable device operated by the slotted bar to release the bolt.
3. In a latch the combination with a slotted bar on the door, of a latch-bar pivoted at the side of the slotted bar; a staple on the frame with which the slotted bar engages; a bolt havin a projection at one side with which the atch-bar contacts to retract the bolt, and a yielding support for holding the bolt while the latter is in the retracted position.
4. In a latch the combination with a stationary bar, on the door, of a pivoted latchbar also on the door; a casing having a recess; a bolt movable in said casing-recess; a staple below said casing-recess, and a movable device between the staple and recess for sustaining the bolt in the retracted position.
5. In a latch the combination with a stationary bar on the door, of a pivoted latohbar also on the door and at the side of the stationary bar; means whereby the latch-bar may be moved vertically; a casing on the frame and having a bolt-recess; a bolt movable in said casing and having a rojection at one side with which the latch-bar may engage; a staple below the casing and bolt, and a leaf-spring projecting through the staple to sustain the bolt in the retracted position when the door is open.
In testimony whereof I affix my signature in presence of two witnesses.
JOSEPH BROADBELT.
