Specification of Letters Patent.

Patented Dec. 1, 1914:.

Application filed March 12, 1914, Serial No. 824,184.

To all whom it may concern: Be it known that I, Gnovnn G. Gnoncn, a citizen of the United States, residing at Zanesville, inthe county of Muskingum and State of Ohio, and useful Improvements in Adjustable Chute-Springs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the, art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in adjustable chute springs especially adapted for linotype and intertype machines and the object in view is to produce a device of this nature which will be adjustable for use in connection with,

matrices of different thicknesses and thereby prevent transposition and congestion of the same.

Heretofore, chute springs made of thin metal and bent at diiferent angles have been employed and provided with frail projectionsor horns which are easily broken off, thereby rendering the device worthless and by the use of which transpositions are likely to occur where matrices are of different thicknesses in the same case as well as congestionbecause-of the angles of the chutes and thus necessitating the operator picking the matrices out and placing them in the assembler. I I

In order to obviate the defects above referred to, chute springs made of two pieces hinged together and acted upon by a coiled spring have been employed, the tension of the spring, however, frequently being too strong to permit matrices to pass through, thereby causing a congestion and, by reason of the spring being under one tension, thin matrices are apt to cause transpositions, thereby rendering a chute spring of this nature undesirable.

It is the object of the generally improve upon present invention to andobviate the defects heretofore met with in devices of this nature and with that end in view, I have produced a chute spring, the tension of which may be varied to meet varying conditions and which is found to, successfully prevent transposition, congestion, etc.

have invented certain new My invention is illustrated in the accompanying drawings, in which:

Figure l is a view in elevation of a part of asingle deck linotype machine, one side wall being removed to betterillustrate the details of the machine and illustrating one of my improved adjustable chute springs in i the place it occupies in the machine. Fig.)

2 is a side elevationof the adjustable chute spr ng, and Fig. 3 is an edge view. I

7 Reference now being hadto the details of the drawings by numeral, 1 represents the assembler. chute of the linotype machine, 2 the assembler rail, 3 the space band buffer and 1 the chute partitions, all of the usual construction in single deck linotype machines.

My adjustable chute spring comprises the two

sections

5 and 6, made of metal and of sufficient thickness to insure rigidity, and the adjacent ends of the two sections have

lugs

7 and 8 respectively, struck up therefrom, which are apertured for the reception of the pin 9, thus forming pivotal connectionv between the two sections. Said section 5 is provided with

slots

10 and 11 through which the adjusting screws '12 pass, affording means for holding the spring chute in proper adjusted positions to regulate the space intermediate the lower end of the section 6 and the assembler rail 2. The section 5 is provided with an integral finger 13 projecting from'its' lower end and which is slotted. as at 16 for the reception of the screw lat which is fastened to. and projects from the face of the section 6.

washer 15 is mounted upon said'screw and a coiled spring 17 is interposed between said washer and thesection 6. .Athumb nut 18 with milled edge and threaded aperture is fitted to the threaded end of said screw and affords means for varying the tension of the spring 17 A resilient finger19 is fastened by means of rivets 20, or other suitable means to the section (3 and its free end' By the provision of an adjustable chute spring made in accordance with my invention, it will be noted that the coiled spring has a direct end thrust and is made adjustable by means of a thumb nut, accessible to the operator while sitting at his machine without the necessity of the services of a machinist. When thin matrices are to be used, adjustment may be easily made in on der to prevent transposition and congestion and vice 'versa. By the turning of the thumb nut, the lower end of the section 6 may be brought nearer to or farther away from the assembler rails as desired, the slightest adjustment of the thumb nut in either direction being suflicientto allow sets of matrices of different thicknesses to be operated Without removing the spring from its permanent position.

By the provision of a chute spring constructed in accordance with my invention, the sections may be made of heavy rigid metal to withstand excessive usage and may be readily adj usted by direct end thrust to the spring, the device being readily adapted for matrices of different thicknesses and avoiding any transposition or congestion of the matrices.

hat I claim to be new is:

1. An adjustable chute spring for linotype machines comprising two sections which are pivoted together, a screw fas tcned to one section, the other section slotted for the reception of the screw, a coiled spring upon said screw, and a thumb nut upon the latter and cooperating with said sections to regulate the tension of said spring, as set forth.

An adjustable chute spring for linotype machines, comprising two sections which are pivoted together, a screw fastened to one section, the other section slotted for the reception of the screw, a coiled spring upon .Jaid screw, a thumb nut upon the latter and cooperating with said sections to regulate the tension of said spring, and means for holding the thumb nut in an adjusted position, as set forth.

3. Anadjustable chute spring for linotype machines, comprising two sections which are pivoted together, a screw fastened to one section, the other section slotted .for the reception of the screw, a coiled spring upon said screw, a thumb nut upon the latter and cooperating with said sections to regulate the tension of said spring, and an attachment to one of said sections adapted to engage and hold the thumb nut in an adjusted position, as set forth.

4:. An adjustable chute spring for linotype machines made up of two sections pivoted together, one of said sections having a slot in a projecting end thereof, a screw fastened to one of said sections and passing through said slot, a coiled spring upon said screw, and a thumb nut upon the latter, bearing against said slotted end of the section and forming means to regulate, by direct end thrust, the tension of said spring, as set forth.

5. An adjustable chute spring for lino type machines made up of two sections pivoted together, one of said sections having a slot in a projecting end thereof, a screw fastened to one of said sections and passing through said slot, a coiled spring upon said screw, a thumb nut upon the latter bearing against said slotted end of the section and forming means to regulate, by direct end thrust, the tension of said spring, and a resilient attachment secured to one of said sections and adapted to engage and hold the nut in an usted position, as set forth.

6. An adjustable chute spring for linotype machines made up of two sections pivoted together, one of said sections having a slot in a projecting end thereof, a screw fastened to one of said sections and passing through said slot, a coiled spring upon said screw, a washer upon the latter and against which the spring bears, a milled nut upon the screw, and means for holding the nut in an adjusted position, as set forth.

7. An adjustable chute spring for linotype machines made up of two sections pivoted together, one of said sections having a slot in a projecting end thereof, a screw fastened to one of said sections and passing through said slot, a coiled spring upon said screw, a washer upon the latter and against which the spring bears, a milled nut upon the screw, and a resilient finger fastened to said plate, its free end engaging the milled edge of said nut, as set forth.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
