Application filed May 9, 1901. Serial No. 59,391. (No modelt) 10 (ti/7 whom it may concern:

Be it known that I, FRANK O. RINsoHE, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Calculating-h/Iachines, of which the following is a full, clear, and exactdescription, such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevational view, partly in section, of the rear end of my improved calculating-machine.

Fig. 14: is a detail View of the clutch-disk driven by the motor, and Fig. 15 is a front elevational view of the motor and its cooperating mechanism.

This invention relates to a new and useful improvement in calculating-machines, being designed particularly asan improvement upon the calculating-machine patented to me July 2t, 1900, No. 654,181.

The objects of this present invention are to provide devices for locking the total-key in its depressed position for preventing the elevation of said total-key after the operatingshaft has started its stroke. When the operating-shaft has completed its stroke, the total-key is automatically released.

Another object is to provide locking de vices whereby when the operating-shaft is initially rotated the keys, while it is possible to restore them to their normal positions, cannotagain be operated to place a different example on the keyboard before the completion of that operation of the operating-shaft.

Another object is to provide mechanism for preventing the setting up of key-stops when the total-key is manipulated.

Another object is to print the total in a color different from that of which its items are composed from a single ribbon.

Another object is'to provide a lock for the segment which actuates the transferring devices for preventing a second operation of the main or power shaft until the segment has completed its work.

Another object is to dispense with the use of an operating-handle, and consequently the manual labor involved in operating the machine, and to provide in lieu thereof a motor having suitable connections with the operating-shaft whereby upon the depression of a key the motor is connected to the machine and makes a complete operation, said motor being automatically disconnected from the machine upon the conclusion of such operation. With these objects in view the invention consists in the arrangement, construction, and combination of the several parts, all as will hereinafter be described and afterward pointed out in the claims.

The type of machine shown in the accompanying drawings is si milar to that illustrated and described in my former patent referred to. This machine comprises in its construction akeyboard composed of depressible keys 8, one or more of which are designed to be struck by the operator to set up an example to be introduced into the machine. Upon the depression of any key of aseries it is desirable that all the other keys of that series be locked against depression, as described in my said patent, the depressed key setting up a stop with which cooperates slide-bars 32. These slide-bars are provided with projections at various points to cooperate with the different key-stops. In my former patent an operating-handle located at the side of the machine is pulled forward, causing the slidebars to be moved forward by friction until arrested by the stops set up by the depressed keys. In the machine of this present application this operating-handle, which is indicated in dotted lines and marked 58, may or may not be used. A main shaft 57, to which the handle or other power devices are connected, is rocked in opposite directions to operate the different mechanisms in the machine.

Referring now to the operation of the machine of my former patent, when the shaft 57 is rotated or rocked forwardly the slidebars 32, which are released upon the depression of a key, are moved forward by frictional devices until the released slide-bars are arrested by the key-stops in one of nine positions, depending upon the key struck.

When the slide-bars are forward, the main shaft 57 is rocked or rotated reversely, and mechanism is operated to cause pivotedracks 39, carried by the slide-bars, to engage the gear-wheels of the adding mechanism, which engagement continues during the backward rotation of the shaft, so that in restoring the slide-bars to their normal or rearmost position the adding-wheels in mesh with the pivoted racks are rotated proportionately to the forward movement of the slide-bars. There are transferring devices in the machine for operating the next adding-wheel in advance and of higher order. When the wheel of lower order is rotated the distance of ten teeth-as, for instance, when the wheel operated by the units-column is moved the distance of ten teeth-the transferring mechanism will actuate the wheel in the tens-column, moving it the distance of one tooth, so that O will be exhibited by the units-wheel and l by the tens-wheel. This of course is where the ma chine operates on the decimal system. This transferring mechanism is actuated by a segment 99, which segment when the shaft,57 moves the slide-bars forwardly is elevated by appropriate mechanism, and in being raised to this highest position power is stored in a spring, whereby when the segment is released the spring forces it downwardly, so that the rotating shaft 97 is operated, and on this shaft are resettingpins spirally arranged for cooperating with the trip-frames of the transferring devices. In taking a total of a sum of numbers introduced into the adding mechanism a lever designated as the total-key is depressed, which lever effects the engagement of all of the pivoted racks on the slidebars with the adding-wheels prior to the initial rotation of the power-shaft 57, so that upon such initial rotation of this shaft the gear-wheels are caused to rotate in what might be termed a reverse direction until arrested by appropriate projections coming in contact with suitably-located stops, so that all of the adding-wheels exhibit 0 through the sight-openings in the machine. Itfollows that the extent of movement required in advancing the gear-wheels to other than a zero position will correspond to and be identical with the extent of movement required in restoring the said gear-wheels back to a zero position, and thus if any adding-wheels exhibit other than 0 through the sight-openings in the machine said adding-wheels will be rotated in a reverse direction until arrested at a point where 0 is exhibited through the sight-openings. There are also printing or recording devices used in connection with the adding mechanisms, which when the shaft reaches the limit of its initial rotation will impress the condition of the machine on a strip of paper. When the total-key is depressed by moving the same rearwardly to take a total and the shaft 57 is initially rotated to reversely rotate the adding mechanism, if the total-key is elevated when the power-shaft concludes its initial rotation, wherein the adding mechanism exhibits 0 through thesight-openings in the machine, the pivoted racks on the slide-bars will be disengaged from the adding mechanism, so that upon the final rotation of the powershaft the slide-bars will be restored, but the adding mechanism will not be actuated This is What is known as clearing the machine. On the other hand, if the total-key is depressed, the power-shaftinitially rotated, and the total-key held in a depressed position, so as to maintain the engagement between the pivoted racks and the addingwheels, the power-shaft in its final rotation will in restoring the slide-bars cause the pivoted racks to rotate the adding-wheels in a forward direction and cause the total to again appear through the sight-openings in the machine when the handle reaches its real-most or normal position. This may be termed taking a total and keeping the total in the machine.

Referring now to Figs. 5 to 10, shaft 57 carries a quadrant 106, with which quadrant cooperates a projection 111 on a lever 110, which lever is pivoted to a rock-arm 109, mounted upen a rock-shaft 50. This rockshaft carries slotted rock-arms which cooperate with slide-bars 32, (shown in dotted lines,) said slide-bars having projections which are arrested by the key-stops before referred to. 127 indicates a lever pivoted in the side frame of the machine, which frame is shown in dotted lines in Fig. 5, to which lever is connected a rock-arm 128, said arm having aslotand-pin connection with a lever 129, pivoted inside of thesideframingofthe machine. This lever 129 is provided with a slot in its rear end for cooperating with the pin 130, projecting from an arm 109. In the ordinary operation of the machinethat is, when the arm 109 is moved backwardly and forwardly by the quadrant 106-pin 130 idly vibrates in that portion of the slot in the rear of the arm 129 which is concentric with the axis of movement of arm 109. When lever 127 is moved rearwardly to depress the front end of lever 129, the rear end of said lever will be elevated, so as to cause the pin 130 to be located in the obliquely-arranged slot in the rear end of said lever 129, which results in moving the arm 109 forwardly, which movement effects the engagement of the pivoted racks 39 with the gears 88 of the adding mechanism. The elevation of the rear end of lever 129 to accomplish the above also causes the projection 111 on the lever 110 to be raised out of the groove or slot in the periphery of the quadrant, this being done by means of a projection 131 on the lever 110, which projection extends laterally over the rear end of lever 129. (See Fig. 7.) A spring 132 exerts a pressure to hold the lever 110 down at all times and to likewise hold the lever 129 depressed by reason of the lateral projection 131. This lateral projection carries guide-pins 133 011 each side of the lever 129 to guide the projection 111 in its downward movement and cause it to reenter the slot in the quadrant. Assuming now that. the total key or lever 127 is depressed, as shown in Fig. 9, it will'be observed that the rear end of lever 129 is elevated, which results, as before stated, in causing the engagement of the pivoted racks 39 with the gears 88 of the adding mechanism. Upon the initial movement of the powershaft the gears 88 will be rotated reversely,

assuming that they exhibit other than 0" through the sight-openings in the machine, until O is exhibited through the sight-openings. If the lever 127 is elevated when the shaft 57 concludes its initial rotation, the arm 109 will be rocked, so as to cause the disengagement of the racks 39 from the gear-wheels, permitting the gears to remain stationary, exhibiting 0 through the sight-openings, While the shaft 57 makes its final movement. i It has been found with respect to the machine shown in my former patent that inexperienced operators will sometimes seek to obtain a total from the machine after starting to rotate the shaft 57, with the result that while the total is exhibited through the sightopenings such initial movement of the shaft is sufficient to prevent a full stroke being given to the slide-bars, and consequently, as the printing mechanism is controlled directly by the position of the slide-bars in printing a total, a false total will be impressed on the paper. To obviate this difficulty, I have provided mechanism for preventing the operation of the total-key after the shaft 57 has been started. In addition to this I have providedmeans whereby should the total-key be depressed before the shaft is operated the total-key will be automatically released and be permitted to rise when the shaft concludes its initial movement, so that the machine will be automatically cleared after obtaining a total from the adding mechanism. If it is desired to retain the total in the machine, the operator will be compelled to hold the totalkeyin its depressed position. The automatic clearing of the machine after obtaining a total is desirable in that inexperienced operators have after setting up an example in the machine and obtaining a total left the totalkey depressed and condemn the machine, because it would no longer record examples they attempted to introduce therein.

To prevent the total-key being operated after the power-shaft has been started, I arrange a track extension at on the quadrant (see Fig. 7) and provide a pin or projection b on the lever 129 in advance thereof, which projection when the quadrantvis moved rides over said track extension and prevents the lever 127 being operated. (See Fig. 8.) In the event that the lever 127 is depressed before the power-shaft is started the projection 12 will be carried below the track extension (see Fig. 9) and the total-key will be locked in its depressed position when the power-shaft is operated and until said power-shaft has completed its initial movement. This is desirable in that it insures the obtaining of the proper total and prevents inexperienced 0perators from depressing the total-key, starting the power-shaft, and then elevating the total-key, which of course would disengage the pivoted racks from the adding-wheels before the power-shaft completes its movement, and so prevent the proper total being ob tained. This track extension a extends such a distance as to lock the total-key in its depressed position until the power-shaft concludes its initial movement, the rear end of said track extension being designated by the dotted line 0, the quadrant being shown in its extreme forward position in dotted lines in Fig. 10, wherein the projection 1) permits the lever 129 to rise, as shown by dotted lines.

To look the total-key in its depressed position independently of the track extension before referred to, I provide a pin or projection 61 on the forward end of lever 129, which is designed to engage under a shoulder e of a spring-pressed lever f, said lever being pivotally mounted upon a shaft g, secured in the side framing of the machine. When the total-key is depressed and the pin d under the shoulder e, as shown in Fig. 9, it is necessary to start the power-shaft for the purpose of taking the total before the pin (6 on the forward end of lever 129 can be released, this release being effected by the forward edge of the quadrant contacting with a projection to disengage the shoulder e from the pin d, as shown in dotted lines in Fig. 10.

It will be understood that the mechanism above described is inclosed in a casing and is inaccessible to the operator, so that when the total-key is once depressed it must be fully depressed before the power-shaft can be operated, the full stroke of the total-key looking it independently of the movement of the power-shaft.

When the power-shaft is started, an auxiliary lock is operated in the way of the quadrant-track, codperating with the pin 1). WVhen the power-shaft concludes its initial movement, the quadrant track releases the pin Z), and coincidently the leverf is rocked to release pin (Z. The spring 132 through lever 110 depresses the rear end of lever 129 and automatically restores the total-key, (clearing the machine,) unless the total-key is held in its depressed position by the operator for the purpose of keeping the total in the machine.

In operating the machine of my former patent inexperienced operators would sometimes initially move the power-shaft 57 to add an example set up on the keyboard in the machine, after which they would operate the release-key and restore all of the keys and set up another example. They would then continue the initial movement of the power-shaft 57, with. the result that neither sum set up on the keyboard would be registered in the adding mechanism; Besides, a number would be printed which would not correspond with either sum set up on the keyboard. To obviate this, I provide the shaft 57 with a projection 1', (see Fig. 2,) which in the normai position of said shaft engages the end of a leverj. The opposite end of this leverj carries a link 70, connected to a frame Z, said frame being vertically movable and carrying independently-movable spring-pressed fin-.

gers m, which cooperate with the ends of the sliding plates 15 of the keyboard. These sliding plates 15 are common to a series of keys, and when one of the keys of a series is depressed said plate is released and moves forward. When the shaft 57 is at home, the released plate moves under its spring-pressed finger'm. Atterthekeyshavebeen depressed to set up an example and the various plates 15 are in their forward position the initial movement of the power-shaft 57 will depress the frame Z and locate the spring-pressed pins 072 in front of all the plates 15 which are not in a forward position. These plates 15 which have been advanced will be in the path of the pins m, so that said pins are forced upwardly into the frame. If an operator now attempts to stop the power-shaft and restore the plates 15, he may do so; but he cannot set up another example on the keyboard, because all of the pins on will drop in advance of the restored plates 15 and prevent their forward movement until the power-shaft has completed its operation and been returned home, so as to raise the frame and the pins m out of the path of the plates 15.

It has also been found from experience that operators unfamiliar with the machine would. accidentally or otherwise depress the totalkey and with the total-key depressed set up an example on the keyboard and attempt to take the total at the same time that they endeavored to place a new sum in the machine. This of course would produce confusion in the results printed by the machine and exhibited by the adding mechanism. To avoid this, I arrange means for restoring the plates 15 upon the depression of the total-key, whereby even if an example has been set up in the machine before the total-key is depressed the machine will be freed from said example, and when the total-key is depressed it will be impossible to place another example on the keyboard previous to a complete operation of the power-shaft 57. The plates 15 are restored manually or mechanically by a rocking frame 23, and to this frame by a slot-and-pin connection is connected a link n, which link is connected to a rock-arm common to the lever 134, which lever is pivoted to the inside framing of the machine and bears against the under side of a pin on the rock-arm 128. The forward end of this lever 134 carries a frame 135, whose upper crossbar 136 extends beneath the rear ends of the fingers of the bell-crank levers 44, on which levers are arranged latch-pins 42, which in ordinary operation prevent the slide-bars 32 from moving forwardly when their frictiondrivers are actuated, except when a key has been depressed, and a locking-plate 15 cooperate's with the bell-crank lever to raise the latch-pin. The presence of this link n does not prevent the normal operation of the restoring-frame 23; but in the event that the total-key is depressed said link positively moves said restoringframe to restore all plates 15 and prevent the subsequent operation of said plates until the total-key is in its normal position.

In my former patent, which shows two ribbons of different colors, one for the items and the other for the totals, the item-ribbon is normally over the printing-line and all items are printed from this ribbon. The total-ribbon is designed when the total-key is operated to be placed over the printing-line, so that the total will appear in a color diderent from that of which its items are composed. As shown in the accompanying drawings, I do not use two independent ribbons for printing the items and the total, but employ a single ribbon or web which is made up of various colors arranged in longitudinal stripes, so that a stripe of one color will be located over the printing-line while the items are being printed, while a stripe of another color will be located over the printing-line when the total is being printed. The mechanism for operating this single ribbon of two or more colors is substantially the same as that described in my former patent, as are also the reversing devices.

It has been found that where a machine of the type illustrated in my former patent is operated by a handle time must be given to permit the segment to properly operate the transferring devices. Upon the forward movement of the handle or the initial rotation of the power-shaft the segment is lifted and power stored in its operating-spring. When the handle moves rearwardly, or the power-shaft makes its final rotation, the spring connected to the segment forces the same down and operates the transferring devices. If the handle should be pulled forward or the power-shaft initially rotated before the segment completes its downward stroke, some of the transferring devices might be left tripped, so that another example introduced into the machine would perhaps actuate the adding-wheels and said adding-wheels would exhibit a false total, because the transferring devices had not been permitted to operate properly. Moreover, it has been the practice heretofore to require operators to give an idle stroke to the operating-handle before taking a total in order to make sure that all of the transferring devices are operated and at home, so that the proper total can be taken from the machine. By the presence of locking mechanism coopcrating with the segment and now to be described the possibility of the machine being operated until the transferringdevices are at home is obviated and the necessity for an idle stroke before a total is taken is also obviated.

65 indicates the reciprocating rod, connected to and operated by the power-shaft of the machine, which rod is provided with a rack at its rear end which meshes with a segment 67, fixed to a cross-shaft 68. (See Fig. 1.) This cross-shaft carries devices for preventing a return movement of the power-shaft 57 similar in all respects as shown and described in my former patent referred to. Shaft 68 to all practical purposes has an initial rotation and a final rotation similar in all respects to the power-shaft 57 and corresponding to what might be designated as the for- \vard-and-backward movement of the operating-handle;

Referring now to Figs. 11 and 12, it will be observed that the shaft 68 carries an arm n, which arm is provided with a stud at one end passing through a slot in a link 0, the other end of said link being connected to a segment 99. This segment meshes with a pinion 100 of the transferring mechanism, and suitable pawls are provided, (see Fig. 1,) whereby upon the upward movement of the segment (when the handle is being pulled forward) the shaft 97is permitted to remain idle; but when said segment descends said shaft, with its carried projections, is rotated to restore the transferring devices. p indicates a spring connected to the segment 99 and in which power is stored when the segment moves upwardly. The stored energy in this spring operates to return the segment and rotate the pinion 100. q indicates a heel on the segment which cooperates with a spring-pressed detaining-pawl r. This detaining-pawl r is operated by a pin 3, projecting from one extremity of the arm n. A bell-crank lever mounted upon the frame of the machine has one of its members i in the form of a hook or detaining-pawl for cooperating with a pin u ment.

on the arm a, while the other of its members a) is in the path of the segment 99 and is designed to be struck by said segment when the segment is in its normal position.

Referring now to Fig. 1, where the parts are in their normal position, it will be observed that the segment is in engagement with the bell-crank lever and the hook end of said lever is out of the path of the pin u; also, that the pin .9 is in engagement with the detaining-pawl r, holding the same away from the heel of the segment. in is against the upper end wall of the slot in the link 0, so that the initial rotation of the shaft 68 will move the parts to the position shown in Fig. 11. In this position it will be noted that the arm n has swung around so as to release the detaining-pawl r and that said detaining-pawl has engaged and holds the segment in a retracted posit-ion or in a position to drive the shaft 100 when the detaining-- pawl r is operated. As the detaining-pawl 'r is controlled by the pin .9 on the arm 1t, it follows that as said pin will not contact with said pawl until the parts are in the position shown in Fig. l the shaft 68, as well as the power-shaft 57, will have returned to their normal or home positions before the segment 99 is tripped and can operate the shaft 100. Thus all of the slide-bars 32 must be restored home and all of the transferring devices which are to be tripped must be tripped before the segment is released and becomes operative. The return of the shaft 68 to its home position will, as shown in Fig. 12, move the detaining-pawl r, so as to release the seg- The segment must now travel from the position shown in Fig. 12 to the position shown in Fig. 1, or must rotate the transferring-shaft 100 one complete revolution before the segment will contact with the member 1) of the bell;crank lever and force the hook member t of said lever out of engagement with the pin to on the arm n. Thus the shaft 68 is locked against movement while the segment is traveling from the position shownin Fig. 12 to the position shown in Fig. 1, and consequently neither the operating-handle nor the power-shaft 57 can be started on another operation until the segment 99, which operates the transferring devices, has completed its work. Itis of course obvious that as the shaft 68 must be home before the segment is released the stud on the arm 97. offers no obstruction to the downward movement of the link through whose slot it passes. Suitable projections or pins are provided on the bell-crank lever, composed of the members t and v, for arresting and limiting the movement thereof. In the event that any at- The stud on the arm temptismade to pulltheoperating-handlefor- I ward when the parts are in the position shown in Fig. 12 it is obvious that said handle cannot be moved on account of the lock effected by the hook member if engaging the pin it. However, as soon as the segment contacts with the member 11 the hook t is forced out locked against rotation.

of the path of the pin it and the operatinghandle can be operated. It will also be noticed that the transferring devices are operated and restored by the returning-spring connected to the segment. The simplicity of such an arrangement is important, as there is little liability of this single spring becoming disarranged or getting out of order; but if anything should happen to the spring or for any reason the segment is locked in its upper position, as shown in Fig. 12, the machine cannot be operated, as the power-shaft is In order to govern the movement of the segment, I provide a dash-pot W', whose plunger is connected to said segment, (see Fig. 1,) and in this manner the segment is not only cushioned in its downward stroke, but the speed of movement of said downward stroke controlled.

Throughout the above I have referred to the power-shaft 57 and have spoken of the initial movement of said shaft corresponding tothe forward movement of the operatinghandle arranged thereon and of the final movement of said handle as similar to the return of the operating-handle. This has been done to harmonize the description as near as possible with that contained in my former patent. I will state, however, that this present application contemplates, so far as the above features are concerned, a machine whose power-shaft is operated bya manually-controlled handle or one wherein said handle is dispensed with and said powershaft driven by a motor.

Referring now to Figs. 13 to 15, inclusive, I have shown a calculating-machine of the type above described, whose power-shaft 57 is provided with a segment A in mesh with a segment B. A link 0 connects the segment B to a driven clutch-disk D, loosely mounted on a counter-shaft. Fixed to this countershaft and in juxtaposition to said disk is a driven clutch member E in the form of a ratchet. F indicates a motor having a wormgearing for driving the ratchet clutch member. In practice I prefer that this ratchet clutch member shall be constantly driven. As shown in Fig. 14, the disk E is provided with a spring-pressed lever G, one end of which is designed to engage the teeth of the ratchet member of the clutch, while the other end thereof cooperates with one end of a bellcrank lever 11, arranged in its path. This bell-crank lever is held in its normal position by a suitable spring and connected by appropriate devices to a depressible key I, preferably arranged on the keyboard of the calculating-machine. A brake J in the form of a yielding finger cooperates with the projection on the disk E for arresting said disk upon the completion of one revolution thereof when the lever F is thrown out of engagement with the ratchet member of the clutch. The operation of this motor attachment is as follows: When an example has been set up on the keyboard, instead of reaching forward to grasp the operating-handle to pull it forward to the limit of its movement and then release said operating-handle and waiting until it reaches its rearward or home position before setting up another example on the keyboard the operator after setting up the example simply touches the motor-key I. This key upon being depressed withdraws the end of the bell-crank lever H out of the path of the lever Gr, so that the spring cooperating with said lever G immediately becomes eifective and forces the inner end of said lever in the path of one of the ratchet-teeth of the driving member of the clutch. The instant that the inner end of the lever G is caught by the driving clutch member the disk E starts to rotate and to vibrate the segments A and B. Upon the completion of one revolution of the disk E, if the keyI is in its normal position, the protruding end of the lever G will contact with the bell-crank lever H to be disengaged from the driving clutch member. At the same the spring-finger-Iwill contact with the projection on the disk E and prevent momentum from carrying said disk beyond its home position. Thus it will be seen that it is only necessary for the operator to temporarily depress the key I, when the motor will become effective to drive the machine, similar in all respects to one complete operation of the operating-handle. K indicates a pawl pivoted to the frame of the machine for cooperating with the shoulder on the shank of the key I. This pawl is connect-ed by a rod or wire L to a bell-crank lever M, pivoted at some suitable point to the framing of the machine and having one member in the path of the link 0. This bell-crank leveris provided withasuitable spring,whereby when the shaft 68 drives the link o upwardly the bell-crank lever is released and rises, drawing the pawl K against the shank of the key I, so that if said key I is elevated it cannot again be depressed while the pawl is under the shoulder, or if the key is depressed the pawl will ride over the shoulder and rest thereunder when the key I reaches its highest position. Th us the key I is locked against operation until the power-shaft has completed its operation. After the powershaft has completed its operation, as has been hereinbefore described, the stored energy in the segment 99 depresses said segment when it is released by the detaining-pawl r, and in descending said segment will drive the link 0 against the bell-crank lever M, depressing said bell-crank lever and moving the pawl K from under the shoulder of the shank of the key I. The key I cannot again be operated until all the parts of the machine have reached a normal position. When this normal position is reached, the keyI is released and can be again depressed to connect the motor with the power-shaft. N indicates a link connected to the bell-crank lever and arranged at the lower end of the key-shank, which link has a slot-and-pin connection with the segmentB. The function of this link is to compel the restoration of the key I when the power-shaft completes its initial rotation. This is accomplished by the engagement of the pin on the segment B with the end wall of the slot in the link N when the segment B is approaching its rearmost position, and in its final rearward movement the segment B, by this link connection, positively forces the key I upwardly and restores it to its home position. An operator cannot depress the key I and hold it in a depressed position, as said key is positively forced upward to its home position and through the instrumentality of mechanism before described locked in such home position until not only the motor has completed its work, but also until the driving mechanism for the transferring device has completed its work.

I am aware that minor changes in the arrangement, construction, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.
