LOCK.
Application filled December the following is a full, clear, and exact de` scription. Y Y
My. invention relates v.to combination locks, and one of the objectsof my invention is to provide a lock of. this character which is mostsiinple in construction', and hence inexpensive in manufacture..
Another objectlof theinvention isto provide aA combination lock which.I is; entirely safe, and which iscapablelofalmost an infinitev number, of combinations.:
Further objects and advantages ofthe invention will appear as the description pro-V ceeds.: e 1 Y. l
For a complete` illustrationof the inven tion reference vis to be had to the accompanying drawings, in which; y
Figure 1 is aperspective viewfof the lock in closed position. Q
Figure 2 is a vertical sectional view taken throughthe lock. Y
Figure 3 is a horizontal sectional view taken on line 3-3 of Figure 2, and showing theflocking screw as. engaging the shackle.
Figure 4 is a view similar'to Figure 3, but showing the shackle released 'from the locking screw.
Figure 5 is a vertical sectional view taken on line 5 5 of Figure 4, and showing the shackle in elevation in closed position, and in broken lines in open position.
Figure 6 is a side view of a slightly modified .form of the invention. Y y
Figure 7 is a transverse section of the modified forni ofthe invention, and taken on line 7 7 of Figure 6, and,
Figure 8 is a detail sectional view showing how the locking screw is keyed on the spindle.
Referring to the drawings more in detail,` numeral l refers to the body of the lock, which is adapted to receive the two legs 2 and 3, of the shackle 4. The shackle is passed through the lock body, and the end of the longer leg is swaged as indicated by numeral 5, to prevent it being entirely withdrawn from the lock body. Flanges 6 and 7 are provided on the legs of the shackle to completely cover the openings in the lock body when the shackle is in locked position.
14, i921. serial No. 522,242.
Each leg of the shackle is provided with f. a plurality ofv grooves 8, andl preferably thesegrooves are screw-threaded'as shown. ln the present instance we have shown three groovesineach leg, but it willbe obvious fromV the .description hereinafter `that two ofthe grooves will be sucient for most purposes.,`
Passing. transversely through the lock body and screw threadedly engaging the lock body and the notches in the shackle, are three locking screws .9, having finger knobs l0 or otherr means for rotating. them. lt
will bepunderstoodof;course, that if only two notches. are provided in the legs of the shackle then only two locking screws will be employed. The locking screws are swaged, as yindicated by numeral l1, toprevent `the withdrawalthereof, and each of the locking screws is provided with two grooves indicated. by numeral l2. An inspectionof Figure .3 will clearlyV show how the locking screws engage the groovesprovided in the shackle legs 2 and 3, and thereby` prevent the withdrawalof theI shackle; whilev Figure 4 shows another. position of the locking screw', wherein the. groovesin thelocking screw are in proper position relativef to theshackle to permit the withdrawal ofthe latter. y f
It isbelieved that the operation of the lock will be obviousfroin the above description. When the shackle is to be locked it is pushed in and the locking screws rotated thereby engaging the grooves in the shackle and preventing its withdrawal. Now when it is desired to release the shackle, each of the locking screws is rotated the necessary number of turns to bring the grooves of the locking screws into alignment with the shackle, and thereby releasing the latter. Of course if preferred, indicia may be employed in any desired manner to assist in getting the exact combination.
It is to be noted here that in order to bring thev grooves of the locking screws in such relation to the shackle as to release the latter, it is necessary that twoV conditions be fulfilled; first, there must be suflicient translation of the 'screw to bring the grooves into Valignment with the legs of the shackle; and second, the screw must then Lbe rotated just sufficiently to bring the grooves into the proper radial position with relation to the shackle legs.
Of course if only one locking screw was employed it would be possible to release the shackle by trial, and without knowing the combination;V but when two locking screws are employed it is obvious that it would be necessary to know the combination in order Therefore it is to bev to release the shackle.
' understood that while I have shown three three locking screws.
locking screws, two such screws will provide a perfectly safe lock, and it is therefore not my intention to be limitedl to the use of And on, the other hand it may be that I would prefer to use more than three locking screws in some instances. n y
With reference tothe modification shown in Figures 6, 7 'and 8, the shackle remains the same asV previously described, and the only difference is in the manner of moving the locking` screws. In this form I employ three spindles 13, which are rotatably mounted in the lock body', but which have no longitudinal movement therein. Keyed on the spindles 13 are the locking screws 14, which are the same in construction as those previously described. The spindles are swaged at one end 15,- and are provided with iinger knobs 16 at the opposite ends.
` The key connection between .the spindle and the lock screw causes the lock screw to rotate with the spindle, but permits thelock screw to travel longitudinally of the spindle,
' and the grooves are thus brought into their releasing positionA in the same manner as before described.
Having fully described my invention, what I claim as new and desire t0 secure by Letters Patent is: n
1. A lock including a body and a slidable shackle, the shackle being provided Vwith a groove, and a locking screw adapted to engage said groove, said locking screw also being provided with a gro0vewhereby the shackle is released when the groove on the locking screw is aligned with the shackle. 2. A lock including a body and a slidable shackle, a plurality of grooves provided in each leg of the shackle, and a plurality of locking screws adapted to engage said grooves, each of said locking screws provided with two grooves, whereby the shackle is released when the groovesof the locking screws are aligned with the legs of the shackle.
3. A lock including a body and a slidable shackle, said shackle being provided with a groove, a spindle rotatably mounted in `the body, and a locking screw keyed on said spindle and adapted to engage said groove.
4. A lock comprising a body and a slidable shackle, each leg of said shackle being provided. with a plurality of grooves, a plurality of spindles rotatably mounted in the body, a locking screw keyed on each of said spindles and adapted to engage said grooves, and' grooves also provided in said locking screws, whereby the shackle is released when the grooves of the locking screws are aligned with the shackle.
5. A lock including a body and a slidable shackle, said shackle provided with a groove. a locking member engaging said groove, said looking member also provided with a groove. said grooves adapted to align to release the shackle, the locking member being screw threadedly engaged in the body whereby the alignment of the grooves depends on both the longitudinal and angular position of the locking member.
