FEPECIFIGATION forming part of Letters Patent No. 530,935, dated December 18, 1894.
I Application filed August 28,1894. Serial No. 521,569. (No model.)
. To all whom it mag concern..-
out as follows, reference being had to the ac- 5o ings.
companying drawings, wherein- Figure 1 represents a side elevation of the interior of the improved lock showing the cover of the inclosing case removed. Fig. 2 represents a similar view showing the bolt in locked position. Fig. 3 represents a vertical section on the line 33 shown in Fig. 2. Fig. 4 represents a rear view of the lock shown in Fig. 2. Fig. 5 represents a horizontal section on the line 55 shown in Fig. 1. Fig. 6 represents an interior view of the improved lock showing lever, bolt and tumblers removed; and Fig. 7 represents a detail side elevation of one of the tumblers.
Similar letters refer to similar parts wherever they occuron the different parts of the drawings.
In the drawings A represents the face plate; B, the back plate of the inclosing frame, and C the removable cover of a spring look as usual.
D in Figs. 3 and 5 representsthe door in which the lock is mortised as usual.
E represents the sliding bolt which is actuated bya suitable spring F shown in Figs. 1, 2 and 4. 4
Inside the case is pivoted at g the lever G having a perforation G' through which is inserted the spindle H to the ends of which are secured the handles H, H shown in Fig. 3. The lever G is held in its normal position shown in Figs. 1, 2 and 4. by the influence of a spring I connected to said lever G in any suitable manner. o
On the boltEis pivoted ateaspring pressed lever K having a lip or projection is adapted to engage with the lower end g of the pivoted lever G as shown in Fig. 1 of the draw- The lever K is normally held in contween the handles H, H and the lever G as is usual in spring locks. q
Z, Z and b, c are slotted perforations in the respective plates L, L, B and O to permit an up and down movement of the door knob spindle H and its washers h, h as will hereinafter be more fully described.
To withdrawthe bolt E it is only necessary to depress either one of the handles or knobs H causing the lever G to actuate the bolt lever K andthus cause the bolt E to be withdrawn. It will thus be seen that to unlock the door all that it is necessary to do is to depress either one'of the handles H without turning the same. I
' For the purpose of locking the bolt E Iemploy a keyM adapted to be inserted through a key hole in either of the plates B, G as shown in Figs. 1, 2, 3, 4, 5 and 6. Said key actuates a spring pressed latch N (Fig. 6) pivoted at n and provided with a projection 9?. adapted to engage with notches O, O in the tumblers O, 0 when the latter are in their locked and unlocked positions as is usual in springlocks.
On the rear forward portion of the spring pressed lever K is an inclined or wedge shaped projection k, shown in Fig. 4, which is actuated by the tumblers 0,0 when moved to their forward locked position represented in Fig. 2 by which said lever K is tripped so as to cause the lower end g of the lever G to be disengaged from the lip k on the rear end of the lever K as shown in Fig. 2, and in such locked position of the bolt and its tumblers,
the bolt cannot be withdrawnby the depresknobs or handles H combined with the spring name to this specification, in the presence of pressed bolt E, the spring pressed lever K pivtwo subscribing witnesses, on this 1st day of oted to said locking bolt, and having a wedge August, A. D. 1894.
