Application May 16, 1938, Serial No. 208,271 `9 claims. (Cl. 1919-30) The present invention relates generally to an improvement in typesetting machines and par ticularly to a brake mechanism for restraining the movement of the assembler rail while aline 5 of matrices are being assembled in the assembler box. An ob-ject of the present invention is the pro vision of a brake shoe that will not lose its bite on the assembler rail. 10 A still further object of the present invention is the provision of brake shoes that will prevent looseness in the line o_f mats being formed and thus eliminate V-shaped openings and transposi~ or upper shoe, and a detachably secured means in the lower shoe, the said means adapted for engagement with the assembler rail. Other objects of the invention will be mo-re fully understood from` the following description and claims when the same are read in connec tion with the drawing accompanying and form ing part of this specification in which: 25 Figure l is a fragmentary front elevational View oi' the assembling mechanism of a typesetting machine and illustrating the improved brake Figure 2 is an end elevational View of the brake 30 lever per se upon which the detachable shoes are mounted, the assembler rail being shown in cross section. Figure 3 is a side elevational View per se of the upper brake shoe and illustrating the rotat 35 able ball mounted bearing at the extreme left hand end. Figure 4 is a bottom view,of the upper shoe and illustrating the position therein of the ro tatable bearing. 40 Figure 5 is a side elevational view of the lower brake shoe and illustrating the ñxed ball bearing at the extreme right end, the Vertical dotted line representing a punch bore. Figure 6 is a top plan view of the lower shoe 45 and illustrating the position therein of the ñxed bearing, the dotted line indicating the position 50 reciprocating mechanism therefor. brake I4 that comprises a lever l5, the lower 10 portion of which is provided with ears I@ and il. My novel improved brake, comprises an upper shoe I8 and a lower shoe i9. The upper shoe I8 is provided with a bore 20 into which is mounted for rotatable movement a ball 2l, the 15 bore 2B being slightly in excess of the diameter of the ball 2l. To the right of the midway point, the shoe I8 is provided with a through transverse bore 22 that receives a threaded mem ber 23, the threaded member engaging a thread 20 ed bore 24 in the lever E5, detachably securing the shoe I8 to the lever. It is to be noted that the top face of the shoe I8 impinges the lower face of the ear HG. The lower shoe i9 is pro vided with a bo-re 25 into which is detachably 25 secured a ball 26. Centrally of the bore 25 is a bore 2l and this bore serves as a means for punching out the ball 26 for replacement or shoes in gripping position. or" the punch bore. resents the frame of a typesetting machine to which the assembler rail mechanism is secured. The numeral Iû represents the casing for the matrice chutes, Il the assembler rail and l2 the Pivotally mounted at I3 on the frame 9 is a ‘ tion of Words, and space bands. 15 A still further object of the present invention is the provision of a rotatable means in the top 20 of the assembler rail to its normal position, parts being sho-Wn fragmentarily. Referring to the drawing, the numeral 9 rep _ Figure '7 is an enlarged detail View of the lever carrying the shoes and illustrating the shoes gripping the assembler rail, parts being shown fragmentarily. Figure 8 is an enlarged detail view of the lever carrying the shoes and illustrating the shoes out 55 of contact with the assembler rail for the return turning the ball over to replace a worn spot on the spherical face of the ball. The provision 30 of a ball provides a gripping means that may be used for an indefinite time due to the fact that only a small area of the spherical surface en gages the rail. To the left of the midway point, the shoe I9 is provided with a transverse bore 28 35 whichl receives a threaded member 29, the threaded member 29 engaging a threaded bore 3i) in the lever I5, detachably securing the shoe lil to the lever. The bottom face of the shoe i9 rests on the upper face of the ear Il. In View 40 of the differences in construction of the two shoes as recited, the upper shoe i8 is marked with the letter U and the lower shoe I9 with the letter L to insure the proper positioning of the shoes on the lever I5. 45 As illustrated in the drawing, Figures l, 7, and 8, the shoes are assembled on the brake lever I5, the balls disposed diagonally and due to this positioning of the balls a more positive gripping of the assembler rail is eii‘ected. The provision 50 of the balls, provides a gripping means in which only a small spherical portion oi the balls en gage the edges of the assembler rail, thus in suring a tighter grip than the flat edge brake shoes commonly used. 55 2 2,128,370 The description about to be made of the opera tion of the brake involves mechanism well known in the art and it is deemed unnecessary `to give same in minute detail, therefore a general de scription is deemed sufficient. In the operation of my improved brake shoes, as the star wheel (not shown) deposits the matrices on the assem bler rail, the assembler rail I I is moved to the left against the tension of a spring (not shown) that 10 is connected to an arm 3l’ on the lever 3|, the spring tension acting against the assembler rail through the intermediate pivoted lever 3| having said lower shoe provided with a punch bore for its lower end 33 connected to one end of a link permitting insertion of removing means for said in said shoes, one of said shoes provided with spherical removal means, said spherical means disposed at an angle to each other and adapted to bear on the top and bottom edges of said rail. 4. A brake for assembler rails of linotype ma chines comprising an upper shoe and a lower shoe, gripping means mounted in said shoes bear ing on the top and bottom surfaces of the rail, the vgripping means in the upper shoe loosely mounted for rotative movement, the gripping 10 means in the lower shoe ñxedly mounted therein, 34, the other end of the link 34 connected at 35 gripping means. >5. A brake for assembler rails of linotype ma 15 15 to the assembler rail II. Asv the assembler rail II is moved to the left during the composition of . chines comprising an upper shoe and a lower shoe, a line, it is held in its displaced position by the spherical means mounted in each of said shoes, a brake I4 that comprises the v.lever I5,»the lower portion of said spheres adapted for engagement end of which carries the upper shoe I8 in which with the edges of said assembler rails, and means 20 is mounted the rotatable bearing 2i that engages " inthe lower shoe for permitting insertion of re 20 the upper edge of the assembler rail II and the lower shoe I 9 having the` ñXed bearing 26 that moving means íor said spherical means. engages the lower edge of the assembler rail as illustrated in the enlarged detail view of Figure machines comprising a lever, an upper shoe and a lower shoe, sperical means mounted in said 25 7 of the drawing. The brake shoes I8 and I9 are held in contact with the assembler rail II by the sp-ring 393, one end pulling on the brake lever I5, one end of the spring being secured to the brake lever Iâ and the other end secured to the 30 bracket 3l on the frame. When the composed line is transferred to an assembling elevator (not shown) means well known in the art release the brake I4, the brake lever assuming the position illustrated in Figure 8 of the drawing and a1~ lowing the assembler rail and itsl associated mech anism to return to its normal position. It is to be noted in Figure 8, that in the return position the balls do not engage the assembler rail. My improved brake shoes are adapted for use on typesetting machines, such as the Intertype and Linotype machines and require no- change of mechanism, simply remove screw in the old type of shoes and replace the old shoes with my im proved ball grip shoes. 45 Changes in detail may be made without de parting from the scope of the claims hereto ap pended. .
