SCOTT 2, 11 7,5 76 MEANS FOR CHANGING THE MAGAZINES OF TYPOGRAPHICAL COMPOSING MACHINES Filed Feb. 10, 1937 2,117,576 Patented May 17, 1938 UNTED STATES PATENT OFFICE 2,117,576 MEANS FOR CHANGING THE lVIAGAZINES OF TYPOGRAPHICAL COMPOSING MA C‘HINES Richard Henry Scott, En?cid, England, assignor to Linotype and Machinery Limited, London, England, ‘a registered company of England Application February 10, 1937, Serial No. 125,029 . In Great Britain February 14, 1936 7 Claims. This invention relates to means for changing the magazines of typographical composing ma chinesof the kind wherein a column of super posed magazines is adjustable between distribut ing mechanism and assembling mechanism to bring a selected magazine, or selected magazines, into operative relationship with the said mecha nisms, or to bring a selected magazine into a position in which its delivery end is located above the assembling mechanism to enable the maga zine to be removed frontwise over the assembling mechanism. ’ More particularly, the invention relates to ma chines comprising an adjustable magazine-sup 15 porting frame including a plurality of base~frame members one appropriate to each magazine of the column, and a ?xed frame having side mem bers between which the magazine supporting frame is adjustable. The object of the invention is to provide im 20 proved means for supporting during removal any magazine of the column selected for removal by adjustment of the column, and which is auto matically brought into active position for sup porting the magazine at the front of the assem 2 bling mechanism through the forward move ment of the selected magazine. With this object in View, the invention con sists in a typographical composing machine pro 30 vided with an adjustable column of magazines, comprising, on a ?xed frame in which the column of magazines is adjustable, extensible arms adapted to provide support, during removal, for the magazine which is, for the time being, in the 35 plane of said arms. The invention will be clearly ‘understood from the following description of one form which it may assume (given, however, merely by way of example), and the description will be more easily 40 followed by reference to the accompanying drawing, wherein:— Figure 1 represents a side view, and Figure 2 represents a plan View, of the relevant parts of magazine supports in a typographical 45 composing machine according to the invention; Figure 3 represents a section along the line A--A of Figure 2, and Figure 4 represents a detail modi?cation which may be employed in a device as shown in Fig 30 ures l and 2. In carrying the invention into effect in one convenient manner as shown in the drawing herewith, a rail I parallel with the magazines is secured along each inner side of the ?xed 55 frame and a magazine supporting arm 3 is (Cl. 199-46) mounted to slide against the inner side of each such rail I. For this purpose each arm 3 is formed at its upper end with an outwardly offset portion 4 dovetailed or grooved to embrace the top and bottom edges of the rail 1. 5 The lower end of each arm 3 is formed with an extension 5 offset inwardly, the upper sur face of said extension having a groove 6 ?ared at its upper end, as shown, and located in align ment with a lug l on the respective side of the 10 adjacent magazine of the column. The grooved extension 5 of each arm terminates in a hook 8 which arrests the forward movement of a mag azine being removed and permits such magazine to hang from the arms in a vertical position as 15 shown in Figure 1. The rail 5 is provided at its lower end with a stop 2 serving to limit the downward movement of the arm by engagement with the outwardly offset portion 4 at the upper end of the arm. 20 Each rail i also carries at its upper end a latch or detent 9 which normally retains the respective arm in its innermost position. When it is desired to remove a magazine, the magazine supporting frame is raised or lowered 25 to bring the desired magazine into the plane of the arms 3, and the operator slightly tilts the magazine at its front end to disengage a cross bar such as It on its underside from a recess H in the base frame, and draws the magazine 30 downwardly over the base frame until its lat erally projecting lugs "I" engage with the grooves 6 in the lower part of the arms and contact with the hooks 8 thereof. Further withdrawal of the magazine causes the 35 arms 3 to move outwardly therewith, the weight of the magazine thus being transferred during the forward movement from the base-frame to the supporting arms. When the arms have reached the limit of their outward position as 40 determined by the stops 2 at the lower ends of the rails, the magazine is clear of the magazine column and free to pivot in order to hang ver tically from the hooks of the supporting arms. The ‘reverse operation takes place during the 45 replacement of a magazine, except that the sup porting arms 3 do not necessarily follow the rearward movement of the magazines, and may be returned to normal position by hand. When the invention is applied to machines 50 ?tted with split magazines, (and more especially when this form of magazine is in any position in the column except at the top) it has been found that there is some danger in drawing for ward the front portion of the magazine for re 55 2 2,117,576 moval, that it will slide off its supporting frame before the lugs have properly engaged the grooves 6 for support. In order to avoid this danger the arms 3 may be modi?ed as shown in Fig ure 4. In this arrangement there is mounted upon a pivot l l on the outer side of the offset portion 5, or on the arm 3 adjacent thereto, a platform I2 which can be swung by hand to the position shown in full line, and thus provide intermediate support when the front portion of ?xed frame, and. arms on said ?xed frame for supporting one or another of said magazines during removal or insertion, a slidable or tele scopic member of each arm being adapted for engagement by, and outward movement with, a selected magazine being removed. 3. A typographical composing machine com prising a ?xed frame, a plurality of magazines in a supporting frame movably mounted in said ?xed frame, and arms having parts in slidable 10 a split magazine is being removed. When the arm is in its innermost position the platform I2 engagement with a rail of said ?xed frame, adapt ed to support one or another of said magazines ‘is swung forwards to rest over the offset portion 5 as shown in dotted lines in Figure 4. When 15 in this device a full size magazine is being re during removal or insertion. 4. A typographical composing machine com prising a ?xed frame, a plurality of magazines in a supporting frame movably mounted in said moved, the platform must clearly be swung to the back (full line) position before the lugs 1 can enter the grooves 6, but this need not be done until the arms 3 have reached the outer 20 most position determined by the stops 2 as the lugs bear against the edges of the platforms I2 (in the position represented by dotted lines) and thus move the arms. It must be understood that the invention is 25 not restricted solely to the constructional de tails of the forms described above, since various modi?cations may be introduced as they become desirable or necessary in order to carry the in vention into effect under diiferent conditions and 30 requirements which have to be ful?lled, without departing from the scope of the invention. Having described my invention, I declare that what I claim and desire to secure by Letters Pat ent is: 1. A typographical composing machine pro vided with an adjustable column of magazines, comprising, on a ?xed frame in which the column ofv magazines is adjustable, extensible arms adapted to provide support, during removal, for 40 the magazine which is, for the time being, in the plane of said arms. 2. A typographical composing machine com prising a ?xed frame, a plurality of magazines in a supporting frame movably mounted in said ?xed frame, and arms on said ?xed frame for supporting a magazine during removal or in sertion, a slidable or telescopic member of each arm being adapted for engagement by, and out 20 ward movement with, a magazine being removed, and grooved members on the outer ends of said arms adapted to receive lugs projecting from the magazine being removed. 5. A typographical composing machine as 25 claimed in claim 2, wherein said arms have hook like extremities in which a magazine can pivot in its outermost position. 6. A typographical composing machine pro vided with an adjustable column of magazines, 30 comprising, on a ?xed frame in which the col umn of magazines is adjustable, extensible arms adapted to provide support, during removal, for the magazine which is, for the time being, in the plane of said arms, and auxiliary supporting 35 means positionable between the foremost sup porting part of the magazine base, and the sup porting elements of said arms. 7. A typographical composing machine accord ing to claim 6, wherein said auxiliary means comprise platforms pivotally attached to said arms. RICHARD HENRY SCOTT.
