BELEASING MEANS FOR TYPOGRAPHICAL MACHINES.

Application filed September 80, 1935. Serial No. 59,673.

The object of this invention is to provide releasing means or escapement mechanism for circulating matrix typo-graphical machines, by which the matrices in a magazine may be quickly ejected from the magazine of the machine by the mechanism described and shown in my pending application No. 39,155, filed June 23rd, 1925, wherein certain selective elements of the magazine mechanism are selectively actuated by selective elements of a keyboard mechanism, in such a manner that the matrices as arranged in the standard magazine, may be selectively released by means of keys in a keyboard of any preferred layout of the keys with a view to more efficient keyboard operation by the operator, than is possible with a keyboard wherein the keys are arranged as in these machines; each key directly connected with the release for the channel of the magazine carrying the matrix corresponding with the character of the key by which it is to be released.

A further object is to provide a release or escapement mechanism whereby matrices may be released instantaneously from the magazine of the typographical machine, and which will make imposslble the escapement of more than one matrix from a channel by once actuating the key whereby the matrix in said channel is released.

A further object is to attain the objects above stated, by means of a rotary releasing mechanism which may be actuated instantaneously, but which cannot be actuated except by actuating the particular key whereby the said escapement mechanism of the particular channel is controlled; thus eliminating the accidental release of any matrix from any channel of the magazine, this being attained by automatic locking means for the releasing mechanism. I

A further object is to provide a novel form of escapement or releasing mechanism and channel for matrices, whereby a matrix will travel to the releasing position after the channel is emptied, and the first matrix in the channel will be ejected by a single touch of the key controlling the channel. There is at this time in the present state of the art, no typographical machine having releasing means making this possible.

A further object is to provide a multiple channel escapement in which the rotary-releasing mechanisms herein described is employed.

lVith these and further objects in View, reference may be had to the accompanying drawlngs forming a part of this specification, in wh ch similar characters of reference refer to similar parts throughout the several Views thereof, in Which Fig. 1 is a sectional View through a channel of a magazine showing my rotary escapemcnt applied thereto, taken on the line 11 of Fig 2; Fig. 2 is a fragmentary plan of a magazine showing the escapement means shown in Fig. 1; Fig. 3 is similar to Fig. 1 showing a modified form of my rotary escapement Fig. 4 is a sectional View similar to Fig.

Referring to Fig. 1 of the drawings, 100 indicates the magazine of a typographical machine to which my rotary escapement is applied; 111 is a matrix in position to be ejected, and 121 is the second matrix. 101 is a.

slot in the top plate of the magazine 100, for

admitting the rotary escapement numbered 1002 of a series not all shown, numbered from 1000 to 1090, being one for each channel of a standard magazine. For special magazines there is one rotary escapement for each channel, whatever the number of channels provided in the magazine.

The rotary escapement 1002 is circular in form having segments removed from the peripheral edge, leaving extensions as 1002, 1002 and 1002 with recesses between for admitting the ear of matrix 111 and the toe of matrix 121, so that the rotary escapement acts upon the successive ears and toes of the successive matrices in their order as a gear or pinion acts to move'a movable rack in an ordinary rack and pinion mechanism, when the rotary escapement is rotated. The ro tary escapements are rotatably mounted upon a rod 1100 held upon the machine.

The recesses are so spaced that with the movement of the rotary escapement one third of a revolution the matrix 111 is ejected and another matrix, 121, is disposed in position for being ejected and a third matrix takes the place of the second as shown in Fig. 1.

The manner of rotating the escapement so as to release a matrix will now be explained, as follows: Upon the face of the rotary escapement is provided a plate 1002 having three ratchet teeth, as 1, 2 and 3, adapted for rotating the escapement. A spring releasing member of a series 1201 to 1090, is provided, the one shown being 1202 01 said series. Said spring releasing member is actuated by a series of selective cam rods, as 1101, 1102 and 1103, shown in the drawings in the manner shown in my pending application Number 39,155, or by any preferred means, provided always that the spring releasing. means of each channel is actuated by a key of the key board mechanism, so that the spring releasing member is selectively controlled by a key of the keyboard corresponding with the matrix in the channel controlled by the spring releasing member.

The spring releasing member is so called because it acts to release a matrix by rotating the escapement, upon its own spring power, when the cam rods are actuated so as to permit it to act, and it is restored to its normal position bythe action of said cam rods. Said spring releasing member, has, however, an arched, spring extension, 1202 arrying a awl 1202 which engages the ratchet teeth 1, 2 and 3 of the plate 1002? so that when the member 1202 is lowered the pawl serves to rotate the escapement one third of a revolution, thus ejecting the first matrix and permitting the second matrix to.

take its place ready for being ejected at the next operation of the escapement, and permitting the next succeeding matrix to move into the place of the second matrix. Said spring releasing member 1202 has also an extension 1202, which serves to limit the movement of the member 1202, by contacting with the bracket, 1101 held upon the upper plate of the magazine. See Fig. 1, Fig. 2 and-Fig. 10.

An automatic locking means is provided for preventing the rotary escapement from moving accidentally to permit a matrix to be released, or from rotating in the reverse rotation, when it has been actuated {or releasing or ejecting a matrix, which n'iig'ht happen, by reason of the frictional contact oi the spring pawl, 1202 upon the ratchet teeth 1, 2, and 3 or one of them, hile the spring member 1202 is being restored to normal po sition by the action of the cam rods, as 1101, 1102, 1103 &c. The locking means is shown in slightly modified form in the various tigures, and in Fig. 8 it is shown in perspective according to the modification shown in 3. The term shown in Fig. 1, is substantially the as that shown in F 3 and Fig. 10.

The lockin means comprises, a strip of matcrial adapted for being secured to the plate of the magazine, and having a plurality of spring members, provided thereon one for each of the rotary escapements and numbered from 1 101 to 1 190, the one shown in Fig. 1 of the drawings, being numbered 1402. Said spring member 1 102 is of an arched form and is provided with two pawls, as 1 102 and 1402". The pawl 1402 serves to prevent the escapement from rotating in the reverse direction and forms a positive spring lock, which permits the escapement to rotate in the direction for releasing a matrix, when the spring releasing member is actuated. The pawl 1402 serves to engage the extensions of the rotary escapement and trictionally engages same so that the escapement may be forcibly rotated by the spring releasing member, 1202, but cannot be rotated by the slight force applied thereto by the pressure of the matrices bearing upon the extensions of the escapement. I Aniodified form of the rotary escapement is shown in Fig. 3, wherein, a different bracket, as shown in Fig. 3 and Fig. 9, is used, and a different locking means, as shown in F ig. 3 and Fig. 8. A different spring releasing means is also employed, and different form of ratchet teeth are provided for rotating the escapement. In this form of the de vice, the parts which are unchanged will be designated by the same reference numerals, as those used in the description of the forms already described above, and new reference characters applied to the parts which are modified in form.

Referring to Fig. 3 the escapement 1002 is provided with ratchet teeth in the form of pins, 1, 2 and The spring releasing member 1 02 has a spring extension, 1202 and a hook 1 02 adapted for engaging said pins, 1" 2' and 3" for rotating the escapement. The locking means comprises a strip of material, 1500 and a plurality of spring members, numbered from 1501 to 1590, the one shown in Fig. 3 being 1502, and having a pawl 1502 which prevents the escapement from rotating in the reverse direction. (lo-operating with this locking means is the bracket 1600 having the comb-likearchedmembers, 1601 to 1690, the one shown in Fig. '3 being 1602. Said arched members, as 1602 &c. are spaced so as to admit the rotary escapements between them, and each has an extension upon its ex treme end which serves as a stop 1002 tor the spring extension 1202 01' the spring releasing member 1202 (see Fig. 9). When the spring releasing member is lowered it disengages pin 1 and enga es pin 2 and when restored to normal posit-ion it rotates the escapement. The pin rests in the hook as 1202 and cannot move in the forward direction as required for releasing a matrix. XVhen the spring releasing member is lowered, the said hook will contact with pin 2 and to prevent it from moving the escapement in the reverse direction, the spring pawl, 1502 engages the extension 1002 thereof.

A recess, as 101, is provided in the lower part of each channel of the magazine 100 which serves to permit the toe of the matrix 121 to drop below the level of the channel when the first matrix 111 is released. The upper part of said recess 101 is so disposed that one half of the ear is above it and the other half is resting upon the base of the channel when the ear upon the upper edge of the matrix impacts against the said extension of the rotary escapement. It will be obvious that since the toe of the matrix is but approximately one half as long as the ear, that when the toe impacts against the extension of the rotary escapement, the toe has advanced far enough so that its entire length is over the beginning of said recess and it can drop into the recess and pass beneath the extension of the rotary escapement, and thus the matrix will move forward until the ear contacts therewith and the matrix is ready for release. The same is true whether the channel be empty, or have only one matrix therein, or if it has many matrices therein. This is a novel feature in escapements; that a matrix can always pass directly to the end of its channel,

'without a preliminary operation to position the matrix.

In Fig. 6, is a modified form of the rotary escapement, herein described, in which the escapement mechanism is disposed beneath the magazine of the machine. In this form of the mechanism, the magazine, 100, the matrices 111 and 121 the cam rods, 1101, 1102 and 1103 &c., the spring releasing member 1202, the spring extension 1202 and hook 1202 and bracket, 1600 with its comb-like arched members 1602 and stop 1602 are all substantially the same as in the form shown in Fig. 3; but are disposed under the magazine. The rotary escapement 1702 is one of a series numbered from 1701 to 17 and is mounted upon the common rod or support 1100. This rotary escapement has three extensions so spaced as to provide three spaced recesses therebetween, of just suflicient length to admit an ear of the first matrix and a toe of the second matrix. Said extensions are designated as 1702, 1702 and 1702 and are out upon chords'of the circumference instead of radially in order that they may coincide more accurately with the ear and toe of the first and second matrices respectively as shown in Fig. 6 of the drawings. It should he noted that the edges of the extension normally engage the wall of the matrices and the circumference of the recessed spaces engages normally against the ear and toe of the two matrices respectively.

in the upper plate of the magazine, is a recess 101--1 and an opening 101-2 in which is disposed a spring pawl 1013 held yieldingly upon the plate of the magazine, and said spring pawl, 1013, carries a pad of 1014-.

second matrices in channel.- Said recess 1011 extends as far as the'extreme width of the toe of the second matrix121. It should now be noted that whereas the angular point of the matrix 121, therefore, as soon as the escapement is rotated, said extension following the dotted line of its circumference, said extension will elevate the matrix, forcing the upper toe thereof into the recess 1011 of the upper plate of the magazine and against the frictional pad, 101- l, thereby raising the spring pawl 1013 and releasing the upper car of matrix 111 so that it is free to drop into the chute to the composing chamber of the machine. The movement of the springreleasing member 1202 rotates the escapement 1700 one third of a revolution so that matrix 121 is in the first position or the position ocof extension is in engagement with the wall cupied by matrix 111 in the drawing, and a third matrix assumes the position of matrix 121. The spring locking means described'as applied to the modifications of form of the mechanism hereinbefore described, may be applied to this form also, but the action of the spring pawl 101'3 and the frictional pad, 1014 serve to prevent the escapement moving in the reverse direction, when the hook 1202 impinges against the pin as 1*1, 2 1 and 3 1 respectivelyso that any other form of locking means is not necessary. I

The multiple channel escapement is shown in Fig. 4, Fig. 5 and Fig. 7 of the drawings. The form of escapement is that employed in Fig. 1 of the drawings, but the spring releasing member is that shown in Fig. 3 and Fig. 6. The magazine is designated 100, the slot therethrough to admit the rotary escapement, is designated 101, and the escapement is 1000, and it serves channel 1000; Fig. 7 shows rotaryescapement 1000 and Fig. 5 shows in plan escapements 1000 and 1001 of the series 1000 to 1090. Both escapements, 1000 and 1001 of the multiple channel escapement are actuated by spring releasing member 1201, as will pres ently he explained. The matrices are designated as in'all views of the drawings as'111 and 121 and the support of the rotary escapements is the same as in all views and designated1100. I I c To provide for alternating the action of escapements 1000 and 1001, a circular plate or wheel, 1800, is disposed between the two rotary escapements, 1000' and 1001. Said wheel is mounted upon suitable bearings as 1800 by means of a stub-shaft 1800 and a bracket 1800 is disposed upon said bearing 1800 and against the wheel 1800, being'of an arched shape, and having a plain surface, 1800 shown only in Fig. 5.

.by the selective mechanism of the magazine unit of the machine. Each operation causes the wheel 1800 to rotate one sixth of a revolution f On the right hand surface of the wheel 1800, are three extensions or sprockets, as 1R, 2R and 3-R-; and upon the left hand surface thereof are three sprockets, 1L,2L

and 3L arranged in interstices or alternate relation between the three sprocket-s upon the right side thereof. The sprockets 1L, 2L and 3L actuate ratchet teeth, as 1, 2, and 3 upon rotary escapement, 1000, shown in Fig. 4:, and sprockets 1R, 2-R and 8R actuate ratchet teeth as 1, 2 and 3 upon rotary escapement 1001. V In Fig. 4, the sprockets 1-L, 2L and 8L are shown in dotted lines and sprocket 1-L is in position for contact and engagement with ratchet tooth 1, of escapement 1000, shown also in dotted lines. After one movement of the spring releasing member 1201, the wheel 1800, will have advanced one sixth of a revolution, and sprocket- 1R will be in position to engage, ratchet tooth 1 of escapement 1001, upon the left-hand side of escapement 1001.

In like manner the successive movements of the spring releasing bar each movement moving the sprocket wheel 1800 one sixth of a revolution, alternately rotates the rotary escapements 1000 and 1001 one third of a revolution, thereby alternately releasing,a matrix, of the same character, first from one channel then from the other channel. In Fig. 7 the ratchet teeth, 1, 2 and .8, of the escapement 1001 are shown in dotted lines, and the sprockets 1L, 2-L and 3L of the sprocket wheel 1800, are shown in dotted lines. These being upon the left hand side of the sprocket wheel 1800, they engage the ratchet teeth 1, 2 and 3 upon the right .hand side of the escapement 1000. It is also obvious that since the sprockets, 1R, 2R- and 3H are upon .the right hand side of sprocket wheel 1800,

that they will engage, ratchet teeth, 1, 2 and 3 upon the left hand side of escapement 1001. This will explain why the dotted tooth 1 of escapement 1001, is dotted instead of being in solid lines, and also, why the sprocket 1L, is not in position for engagement, therewith; since the sprocket 1 R of the sprocket wheel 1800, will not be in position for engaging tooth 1, of escapement 1001, until, sprocket, 1L, has engaged tooth 1 of escapement 1000 Sprocket 1R will then be moved one sixth of arevolution towards the escapement tooth and be in the same relative position as sprocket, 1-L,' but nearer to or in a plane with tooth 1 of escapement 1001, so as to engage therewith and to rotate escapement 1001. If said sprocket 1R were drawn in the perspective View, Fig. 7 in the same relative position as sprocket 1L,then said sprocket would be shown in engagement with tooth 1 of escapement 1001; precisely as I sprocket, 1L is shown in dotted lines, in engagement with tooth 1 of escapement 1000 in Fig. 4. The possibly misleading lines in the drawing in Fig. 7 are entirely due to perspective, since if sprocket 1R were advanced one sixth of a revolution, said sprocket, being upon the side of the wheel nearer to the eye, than the sprocket 1R, it would appear farther to the right in the drawing, and therefore in engagement with the tooth, 1 of escapement 1001, shown in dotted lines because it must be on the left-hand side of escapement 1001, to engage with sprocket 1R,'upon the righthand side of the sprocket-wheel 1800.

A spring locking member is provided for preventing the sprocket wheel, 1800 from rotating in the reverse direction, as 1810, and has a bifurcated end, as spring pawls, 1810 and 1810', which alternately act, to engage the sprockets, upon the opposite sides of the sprocket wheel 1800. The disk of the sprocket wheel, 1800 moves in the bifurcation as 1810 thereby insuring precise and certain move ment of the spring pawls, 1810 and 1810.

A spring locking member is also provided for the rotary escapements 1000 and 1001, as 1820 having a bifurcated portion, with spring pawls 1820 and 1820 each having two pawls, one as 1820 1 serving as a positive lock to prevent the reverse movement of the rotary escapement, 1001, and 1820 2 being a frictional lock to prevent accidental movement of the rotary escapement 1001, but at the same time, yieldingly.holding the said rotary escapement, by impinging upon the extensions thereof as 1001 1001 and 1001 so as to frictionally retain the escapement in position, but admitting of the forcible rotation thereof by the sprockets of the sprocket wheel 1800, when rotated by the spring releasing member, 1201, as described. The arm 1820 of the bifurcated spring locking member 1820, also has two pawls, 1820 1 and 1820 -2 which regulate in like manner rotary escapement 1000.

While I have described and shown in the foregoing specification forms and modifications of forms of the rotary escapement mechanism designed to be employed in typographical machines, adapted to be employed in machines, now in use, and especially in con nection with machines to which the selective mechanism described in my pending application, No. 39,155, I do not wish to beunderstood as limiting my invention to the particular forms shown in the drawings and described in the specification, but reserve the right to depart therefrom to the full scope and intent of my said invention making such modifications and changes in the form and construction thereof as may reasonably be within the scope of my said invention.
