UNITED STATES PATENT GEORGE J. FERGUSON, OF GREENVILLE, TEXAS.

RECORDING DOR=LOCK.

SPECIFICATION forming part of Letters Patent No. 895,319, dated January 1, 1889. Application filed March 16, 1887. Serial N0. 231,l91. (N0 model.)

To all whom it may concern:

Be it known that l, GEORGE JONES FERGU- SON, of Greenville, in the county of Hunt and State of Texas, have invented a new and useful Improvement in Recording Door-Locks, of. which the following is a specification.

The object of my invention is to provide a continuous-recordin g look suitable for bond ed warehouses, factories, stores, public buildings, ot'tices, &c., and by a slight modification applicable, also, for private residences, combining a recording-lock and night-latch and daylock in one mechanism, that will keep an indisputable record 011 a strip of pap er by pun ching a hole in said paper simultaneously with and by means of the withdrawal of the bolt, and which same means serves to record the proper locking of the door by punching a hole in the paper strip simultaneously with and by the act of projecting the bolt to lock the door.

The invention is also designed to provide means to prevent the fitting of a key to open the look without having the lock open or a key to copy from.

The invention can also be conveniently applied to any lock provided with a sliding lockbolt by simply attaching it thereto, as the motion of lock-bolt will adjust record strip or roll as well as operate recording-punches.

Figure 1 shows a side view of the lock attached to a double-hinged door, the upper and lower portions being broken off to shorten the figure, so that the doors show in three sectionsviz., top, middle, and lower section. Figs. 2 and 3 show edge views, respectively, in locked and unlocked positions. Fig. l is an inside view of the lock with the face-plate removed. Fig. 5 is an inside view of outer guard, A. Fig. 6 shows side views of the tumblers. Fig. 7 is a sectional view of the guard A. Figs. 8 and 9 show modifications of plate U and plate T reversed. Fig. 10 a crosssection through a portion of the lockcase, showing the position of the tumblers, Fig. 6. Fig. 11 shows inclines that operate punches on the lock-bolt V. views of the end of the key. Fig. 13 is aside view of the face-plate of the lock. an inside view of the keeper E in which the bolt is secured. Fig. 15 is a view of the record roller-strip R Fig. 16, a detail of the roller G Fig. 17 shows detail views of gear P, ratchet Q, and pawl B. Fig. 18 is a vertical section through lines .121 of Figs. 1 and l.

I will now proceed to explain how the mech anism is constructed and operates.

The lock is securely applied to the inside of the door by screws put through the case B into the inside of the door, and also through holes in the outer guard, A, and the case B at A 7, into the edge of the door. A keeper, 1*), Figs. 1 and ll, is secured byscrews to the face of the casing and also by screws passing through holes E into the door-jamb to prevent the removal of the lock or keeper without unlocking and opening the door and thereby recording on the record-strip.

I provide against imperfect locking of double doors by placing the keeper E on one door, while on the edge 1, Figs. 1, 2, and 3, of the other is arranged a verticallyanoving lockbar, 2, which is secured to the door by screws 5, which engage longitudinal slots in said bar, thereby permitting vertical movement of said bar, whereby it may be projected into the doorcasing 8 on the top of the doors when the lock-bar is raised or in locked position. \Vhen bar 2 is raised, the opening 10 in this barregisters with the lock-bolt V of the lock, and the lock-bolt can be projected and will there retain the lock-bar 2 in position. Lock-bar 2 at the bottom of door has its edges turned toward and into a recess or mortise, l, forming ears (see Fig. 1) to receive a tilting-latch, This latch is slotted and guided upon a pin in the recess and is pivoted to the ears of the bar 2, and when bar 2 is in unlocked or open position this latch -3 will be held up in the recess; but when the lock-baris raised to the locked position this latch is projected downwardly to lock the door at its lower end.

It will be understood that when this lockbar is elevated by the handle U on the inside or the handle '7 on the outside, Figs. 2 and 3, of the door the lock-bolt Y can then be projected and will not only lock the door at v that point, but will also pass through hole 10 Fig. 12 shows different 1 and hold lock-bar 2 in its locked position at top and bottom, so that it cannot be lowered Fig. ll is until the lock-bolt V is withdrawn or unlocked. This obviates the objection to the commonly-used spring-bolts, which being left unfastened the door could be pushed open without unlocking and it further provides against the leaving of doors unfastened; or improperly fastened, as this lock-bar must be in exact position or the lock-bolt cannot be projected, and consequently no record would be made on the record-strip, and the doors being leftperfectly loose and unfastened they would be apt to blow open by the wind. This lock-bar will be retained in open position by gravity, so that it cannot drop down and obstruct the doorduring business hours. This feature can be omitted on single doors, as the keeper E is in that case secured to the doorjamb. It will also be understood that when the lock-bolt V is projected by the handles F tumblers Vt, W, and V, Figs. 4, 6, and 10, will automatically gravitate to locked position.

The working parts are principally con tained in the case B of the lock, the inside section, C, being only a plate having key-hole O and hole 0 for the spindle D and holes C for the screws or bolts which fasten the lock to the door. The case B of the lock is constructed in two parts. The outer guard, A, Figs. 5 and 7, is one part, which is perforated at A to allow the spindle D, Fig. 4:, to pass through, and then extends horizontally and toward edge 1 of the door, Fig. 1, and is secured by screws to the case B, and is fitted into the case B at B, Fig. 4, to insure its rigid maintenance of position. This portion A is provided at A with a slot for the punch G, Fig. 4c, and at A with a round hole for the punch H to allow punchings to escape, and at A with a rubber or flexible pad, I, and at A with a journaled cogged wheel or pinion, J, and at A with a slot or groove, and at A with a round hole, the uses of which will be described presently.

I will now proceed to describe the working parts contained in case B. The space between case B and outer guard, A, (see Fig. 1,) is where the recording-strip R (see Fig. 18) or roll passes through to be operated by wheels K, Fig. 4., which project through the case B, which strip also receives punch-marks indicating if or 110w often the door was unlocked and if it had been properly fastened. These toothed wheels K, Fig. 1, are rigidly fastened to the shaft N, which is suitably j ournaled in the case B at K and K These wheels are of the same diameter, to insure the straight movement of the record-strip, and they answer the double purpose of moving the record-strip and also ineffaceably marking the same by punctures, so that the record-strip could not be used a second time without detection. The plain or blank wheel L may cut off a margin as the record-strip passes between it and slot A, Fig. 5, thus pro viding a further means of detecting and preventing the second use of a record-strip. One of the wheels K engages the pad I, while the other meshes in pinion J to feed the recordstrip which passes between. Either or both means can be used, or two rubber rollers simultaneously operated by toothed gears can be used to move the recordstrip and mark the paper as the paper record-strip would pass between the toothed gears. The shaft N, on w rich the wheels K K and L are rigidly fastened, is formed square at one end toallow the use of a key, M, Fig. 12, having an angular hole, M in its stem to operate the wheels K K and L for the purpose of applying, adjusting, or removing the record-strip without moving the lock-bolt.

On the opposite end of the shaft N is secured a bevel-pinion, O, operated by a bevelwheel, P, loosely journaled on spindle D. This wheel P has attached to it or made in one piece with it a ratchet, Q. This ratchet Q is intermittingly propelled in one direction by pawl R, the said pawl passing over the ratchet in the other direction without moving it, as the ratchet is held from moving back by the detent S at the bottom of the lock-case. This pawl and detent do not prevent the clownward movement of paper recordstrip, nor the adjustment of the same by stem of key M.

The pawl R is pivoted to plate T at T. The detent S is pivoted to the lock-case. The plate T is operated by the spindle D of knob F, Fig. 1, which spindle passes through a square hole at T (see Figs. 4 and 9,) and consequently moves in the same direction and same distance as the knobs or handles. This motion is limited by the projection or withdrawal of the lock-bolt V, and the lock-bolt is guided in its motions by guide-pins V and V It will. be seen that when the knobs or handles F (and thereby the spindle D) are moved in one direction the pawl R passes overthc teeth on the ratchet Q without having any effect; but when moved in the opposite direction pawl R engages said teeth and moves the ratchet until the limit is reached. The ratchet Q imparts this motion to cogvheel P, pinion O, shaft N, and wheels K and L, and thereby brings a fresh portion of the recordstrip opposite the punches G and H by moving it downwardly. This explains how the the paper record-strip is automatically adjusted.

I will now proceed to explain how the lockbolt V is simultaneously moved with the rec-' ord-strip-moving mechanism.

On the opposite side of plate T from pawl R, I fix a stud, T which engages a slot, U, in the plate U. This plate U is pivoted at U to the case B, and is connected to bolt V by slot U engaging the stud V on the lock-bolt V. This plate U is operated simultaneously by the plate T, and thereby has imparted to it a backward-and-forward motion to move the lock-bolt V-to locked and unlocked positions. This plate U can be made with one end in the form of a segment having cogs which engage cogs on plate T, as in Figs. 8 and 9.

It will be understood that a movement of the lock-bolt will operate the record strip or roll even should the motion be imparted directly to the lock-bolt independently of the knobs or handles.

The movement of the lock-bolt V when locking the door can be accomplished by a spring located above it, in which case the face of the bolt next the door-jamb will be beveled, so that it will onlybe necessary to shut the door by a pull or push, when the keeper E will push the bolt back and allow the door to close, the spring serving to force the belt out into the keeper, where it will be secured by tumblers, hereinafter described. This modification makes the lock applicable to private residences. The movement of the lock-bolt to lock the door causes the punch-lever G to ride up an incline, V on the bolt, (see Fig. 4,) and said punchlever G being pivoted at G near its center, the punch G will be pro jected outwardly and punch a hole in the record-strip. As the punch G is operated simultaneously with the movement of the record-strip, it is nectssiry to provide the punch G at G Fig. 16, with a disk having a sharp cutting-edge and journaled in the end of the punch, so that in its outward motion it will to a certain extent allow the record-strip to carry the disk G down and gradually cut a slot in the record strip or roll, and thereby prevent it from stopping or tearing the recordstrip.

The reverse motion of the lock-bolt to unlock the door (or when engaging the keeper in shutting the door) causes the punch l to be withdrawn by the cam portion V Fig. 11, of the lock-bolt, which cam has the opposite effect of the incline Y This motion of bolt V to unlock the door causes the punch-lever H to ride up the-incline V and have the similar effect ot projecting the punch ll outwardly and punching a round or other shaped hole in the record-strip, the record-strip not being moved when unlocking the door. These two punch marks unmistakably indicate whether or not (and how many times) the door has been opened or closed, and also show it the door had been properly secured. The punch H is withdrawn by cam V in case of punch G, and when both punch-levers G and H are in line or on the same level they are both out of the recordstrip, and the recordstrip can then be removed or adjusted by the key, Fig. 12, having angular hole M which key is inserted at A Fig. 5, and is fitted to the squared end of shaft N, Fig. 4.. By turning this key to the right a new recordstrip may be applied, and can be adjusted, so that it will be punched opposite any given number or mark, said record-strip being provided with numbers on its margin. \Yhen this look is used on bonded warehouses or store-houses, the record-strip will have the heading of the department of the Government in. which it is used or the proprietors of warehouse printed on it and spaces for officials, clerks, gagers, or supervisors to (late, give location, and sign. lVhen ready to close and fasten the door, the recordstrip is applied between guard A and case B of the lock, and the wheels K are rotated by the shaft )5 and the key M to draw the record-strip down, and it can be adjusted as wished by the operator or in accordance with the rules of the lovernment or proprietors. Aftertherecord-strip is applied it cannot be withdrawn, but must pass down between the parts A and 13 of the lock in the same direction as applied, as the pawls will not allow a retrograde motion of the record-strip. It is held in position by toothed wheels K and pinion J, between which it is interposed, and it will be seen that it would be impossible to pull the record-strip back or upward without tearing or destroying it. It is also impossible to operate the lock bolt V in either direction without punching the record-strip.

I also provide a means of locking bolt Y automatically in its locked or projected position by automatic gravity-tumblers lV, Fi g. 6, slotted at \Y, to slide vertically on pins Fig. i. Said tumblers are held in open position by rib V", Figs. st and 11, of the lockbolt V when said bolt is in unlocked position; but when lock-bolt V is moved to the locked position rib V is withdrawn and the tumblers are free to drop in rear of the lockbolt automatically and prevent it from being opened or withdrawn except by key M. \Yhen said key is applied through hole C, Fig. 113, and is turned toward the tumblers, it will raise said tumblers the necessary distance to permit lock-bolt V to be moved back to unlocked position by the knobs or handles F. It will be noticed that this key M is peculiarly constructed by havingits bit M hookshaped. This hooked shape is for the double purpose, first, of preventing the use of an ordinary key, and, secondly, for preventing a hat or oidinary key from having any eil'eet on the tumblers \Y, as a flat key would only press against a shoulder, ol' the tumblers, and would have no effect in raising said tumblers. A flat key is still further prevented from raising the tumblers by the stationary plate \V" which is placed between the tumblers and is then bent at right angles toward case B at its upper end, (see Fig. 10,) thereby necessitating the use of a hooked key to pass under, around, and behind this stationary plate to lift or raise tumbler KY next to case B. It is also necessary for the key to have a slot, M Fig. 11, into which the stationary plate VP projects when the key is turned sutliciently to unlock the tumblers \V, W and )Y. Tumblers \V and "can also be raised above the position necessary to allow the rib Y on the lock-bolt V to enter their slots W and this feature makes it almost imposs ble to pick the lock, as each tumbler would have to be operated simultaneously, and would be most likely moved so high that the slot would pass the rib V. This also makes the fitting of a key very ditlicult. As the tumblers are not spring-actuated, they will not resist sufliciently to make an impression on TOO any soft substance used to get the shape of tumblers, and 011 account of the tumblers rising above Opening position it would simply be impossible to fit a key in this manner.

The tumblers can be changed in outline and position so as to require difierent keys in each lock manufactured, although their general structure and features (of being capable of rising above the opening point, and their protection by stationary plate IV, and their close proximity to part V of lock-bolt V) .are retained in each individual lock. This combination is what I especially wish to be understood as adding safety to a lock that has no delicate or complicated parts. The key M can only be applied from the outside of the door, as the keyhole is not cut clear through the lock. hen the lock is used 011 the inside of the door, the key-hole is only cut in plate 0, Fig. 13, but when used on the outside of the door the key-hole will be cut in case B. This is necessary, as the key cannot be made reversible, and it would require a different key to unlock from the inside. It will also be understood that locks will require to be manufactured right and left to suit doors opening in opposite directions. The unlocking of the door from the inside being only necessary when these locks are used on private residences, in such case I add the feature X, Fig. 4: which is a vertically-sliding gravity-catch, which, on being pushed up, raises all of the tumblers to the required opening-point, when bolt V can be withdrawn by turning handles F. This feature will permit the lock to answer the purpose of a nightlatch in addition to its recording feature. This catch X can be made so it will be necessary to let it drop before the lock-bolt V can entirely be withdrawn, or it can be put entirely out of the way of bolt V, there being no springs needed to compel any part to perform its functions, as each and every piece will operate by gravity or positive motion. Still each and every part can be easily made spring-actuated, in which case springs would simply assist gravity in accomplishing the desired object. Then a roll of record-paper is used, I provide a removable metal case, Y, which is retained in position by slides or guides Z, Fig. 1, 011 the outside of case B, the roll being placed in the open end of the case Y, with its lower end projecting, which end can be started in the space between the case B and the outer guard, A. \Vhen the shaft N is rotated by the key M, the toothwheels K will engage the record-roll and move it, as described. This record-roll obviates the necessity of placing a detached slip in the lock each time it is used, as the slip would only record a few openings.

To enable the operator to see whether the lock has been opened since he locked it, the

- record-roll will be numbered consecutively,

higher number being punched. The same obj ect can be accomplished bysigning a name immediately above the outer guard, A, which on looking the door will be moved down in line of punches and effectually indicate if the door had been opened. When slips are used, they can be printed and contain spaces for dates, locations, numbers, private marks, signatures, or any information deemed necessary for security or reference, and when the lock is applied to the outside of doors this can be read and the condition of the record-slip examined and an illegal opening of the door discovered before the door is opened. This application of the lock would be the most suitable for bonded warehouses, factories, stores, and public buildings.

\Vhen this look is used on private residences, an extra set of knobs and bolts can be provided for use in day-time, so that the locking and recording features can be omitted at certain hours.

I do not limit myself to the particular construction shown of adjusting a record strip or roll and actuating the lock-bolt and recordingpun ches. The invention consists, broadly, in the novelty of adjusting a record strip or roll simultaneously with the movement of the lockbolt and recordingpunches.
