LOCK.
Specification of Letters Patent.
Application filed January 23, 1911.
Patented Oct. 3, 1911. Serial No. 604,198.
To all whom it may concern- Be it known that I, VVALLAOE LAFAYETTE SELLnoK, a citizen of the United States, re siding at Platteville, in the county of Grant 5, and State of Wisconsin, have invented a new and useful Lock, of which the following is a specification.
It is the object of the present invention to provide an improved lock in which the bolt is projected solely by gravity, the em ployment of springs in the structure of the lock being in this manner obviated.
It is one aim of the present invention to provide a lock possessing the advantage that it embodies no springs for projecting the bolt, which will be compact in structure and not liable to get out or order.
The invention aims further to provide, in a lock of this type, a novel gravity actuated tumbler arranged to cooperate with the bolt to prevent its retract-ion upon rotation of the knob spindle, when the tumbler is in one of two positions.
In the accompanying drawings, Figure 1 is a view in elevation of a lock constructed in accordance with the present invention, the face plate of the casing being removed. Fig. 2 is a similar view but illustrating the position assumed by the various parts when the bolt of the lock is retracted. Fig. 3 is vertical sectional view on the line 33 of Fig. 1. Fig. 4 is a sectional view on the line 1 1 of Fig. 2.
In the drawings, the lock casing is indicated by the numeral 5 and in the casing there is mounted the usual hub 6 fitted upon the knob spindle 7. For a purpose to be presently explained, an arm 8 is carried by the hub 6 and projects therefrom in the direction of that side of the casing to which the bolt of the lock is projected. The said bolt of the lock is indicated by the numeral 9 and is formed in its under side with a re cess 10 and in its upper side with a notch 11. A rocker 12 is mounted for oscillatory movement in the lock casing below the bolt 9 and has a short arm 13 which projects upwardly.
and is headed'as at 14 and engages at its headed end in the recess 10 in the under side of the bolt. The rocker further includes an arm15 which extends in the direction of the above mentioned side of the lock casing. The bolt 9 is reduced in width as at 16 at a point between its ends so as to leave a space between it and the face plate of the lock casing. A member 17, theupper portion of which is a weight, and adapted to always be in a position to one side of the perpendicular, serves as a connection between the arm 8 and arm 15 of the rocker 12 and this member is comparatively heavy and is pivoted at its upper end to the ex tremity of the arm 8 and at its lower end to the extremity of the arm 15, a portion of the member, indicated by the numeral 18,
being reduced in thickness and extended down beside the portion 16 of the bolt 9 or more specifically speaking through the space between the bolt and the face plate of the casing.
From an inspection of the drawings it will be observed that the weight of the connection 17 serves to hold the rocker in the position shown in Fig. 1 of the drawings, under normal conditions. It also serves to hold the arm 8 in the position-shown in the said Fig. 1. It will now be understood that by rotating the knob spindle 7 toward the right in Fig. 1, the arm 8 will be swung upwardly thereby lifting the connection 17 and oscillating the rocker to retract the bolt 16. Upon releasing the spindle 7 the weighted connection 17, which never moves beyond a perpendicular, will drop by gravity and return the rocker to the position shown in Fig. 1 thereby projecting the bolt 16 in the manner illustrated in the said figure.
When the lock is manipulated in the manner above described, the bolt 16 serves merely as a latch bolt. It is however desirable that the bolt may be locked against retraction through oscillation of the spin dle 7 and for this purpose there is provided a tumbler 19 having upwardly projecting spaced arms 20 and a downwardly projecting finger 21 located at its lower right hand corner in Fig. 1 of the drawings. The tumbler 19 is'pivoted as at 22 at a point substantially midway between the arms 20 at their lower ends so that it may be rocked toward the left or right and will remain in the position to which it is moved. When it is rocked to the left in Fig. 1 of the drawings, its finger 21 will engage in the notch 11 in the upper side of the bolt 9 and thus forming a slight wedge therewith, so that the bolt 9, will be securely held against retraction through oscillation of the spindle 7 The casing is formed with a key hole 23 through which may be inserted a key 24; for the purpose of engaging one or the other of the legs 20 to rock the tumbler to the right or left, as desired.
What is claimed is 1. In a lock, a sliding bolt, a rocker having an arm projecting into engagement with the bolt and an arm projecting at an angle to the first mentioned arm, a knob spindle, an arm projecting therefrom, the bolt being located between the spindle and the rocker, and a member having a weighted upper end and forming a pivotal connection between the last mentioned arm and the second mentioned arm of the rocker, said connection transecting the bolt.
2. In a lock, a sliding bolt, a rocker having an arm projecting into engagement with the bolt, and an arm projecting at an angle to the first mentioned arm, a knob spindle, an arm projecting therefrom, a member having a Weighted upper end and forming a connection between the last mentioned arm and the second mentioned arm of the rocker, and a key operated coupler mounted for rocking movement above the bolt and having a portion arranged to positively engage the bolt when the tumbler is in one position of its rocking movement.
In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
