WILLIAM S. BROWN, OF WICHITA, KANSAS.

RECORDER.

To all whom it may concern certain new and useful Improvements in Recorders; 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.

My invention relates to recorders, the object being to provide an instrument which will at one impulse print the predetermined characters with distinctness and to provide means by which the platen may be struck against the type with as much force as desired without inconvenience to the operator.

Another object is to provide means to present the type' in proper position to be struck by the platen.

Another object is to provide means for quickly changing the type should it be necessary to print other characters.

Another object is to provide means for intermittently rotating back and forth an indelible ribbon.

With these objects in view and others subordinate thereto, the preferred embodiment of my invention comprehends the construction and arrangement of parts which will be hereinafter illustrated and specifically pointed out.

Figure 1, is a general view of my machine. Fig. 2, a locking bar engaging a tooth on the lower side of the cylinder by which means the type is presented in the proper position to be struck by the platen. Fig. a longitudinal vertical sectional view of a stud on which are mounted the printing paper and type ribbon spools. Fig. 4. an

end view of the rollers which move the printing paper along step by step.

Similar numerals refer to similar parts throughout the specification.

My device is substantially in three sections, A, B, and C, mounted upon a rectangular base 1, having a vertical rim 1. Af-

fixed to said rim with screws 16, are plates 2.

approximately triangular which carry rods 10, on which are pivotally mounted locking- Specification of Letters Patent.

bars 11, to which are aflixed vertical standards 13, on the ends of which are keys 14.

I have shown only three keys and lockingbars but it is to be understood that in practice as many can be used as desired, they all beingexactly alike excepting in length, the bars.are mounted in four series which makes the keys accessible to the operator. The other ends of the aforesaid bars have V shaped notches 12, which are to engage the teeth .56, when the keys are pressed down, but when in a normal position rest upon the rods 15, which are afiixed in the member 2. A cylinder 3, having reduced extensions 4, is mounted upon an arbor 9, said arbor is journaled in the plates 2, and on one end of said arbor is a thumb-knob 8.

transverse dovetail grooves 7 in which are placed typo blocks 5, and are retained there in by set screws 6. In the periphery of the extensions 4, are spirally located teeth 56, a. tooth for each type block and set in longitudinal alinement therewith.

Section B, comprising vertical standards 17, having lateral bends 18, are affixed to the base 1, with screws 19. Between the free ends of said standards are journaled rollers 2829-and 30. A portion 66, of the standard is removed to disclose the type bar. A scallop 67, is made in the edges of the said standards to allow the platen free access to the type. Between these standards are positioned indelible ribbon spools 20, which are mounted on studs which are in two sections 61, and 62, screwed together, their free ends progressively enlarging so that when the stud is placed inside the spool and screwed together it will tighten in the spool sutlicient to turn the spools when the studs are turned. A rectan ular slot 65, is made in one end of the studs to receive a pin 64, transversely set in the arbor 63, which passes through the stud. The pin 61, prevents the stud from turning on the arbor. On one end of said arbors arc knobs 26, and 27. and ratchet wheels 21. and 25. the arbor 63. is pivotally mounted in the standards and retained therein by keys 68, a slot 60, is made in one of the standards to allow the pin 61, to pass In the per1phery of the aforesaid cylinder are through to enter the studs. A groove 69, is

' made in the inner'ends of the knobs 26, and

27, to receive the free curved ends of a spring 22, which spring is given a central coil 22, and attached to a hook 23, secured to the lateral projection 18, with a screw 70. The function of this spring is to keep the ribbon spools from over-runnnig; The ribbon 31, extends from spool 20,'over rollers 28, and 29, and around roller 30, then over roller 28, and 29, then around the spool shown in dotted lines 20 which keeps the section 32, clear of the ty e.

Section G, is compose of two vertical plates 35, having lateral projections 71,

their lower ends being rigidly ailixed to a shaft 50, which is 'pivoted in angle plates 33 (the one on the opposite side not being shown .but both are exactly alike) secured to the base 1, with screws 34, the said shaft 50, extends on through an opening in .the rim 1 and has asquared end on which is keyed a crank 51. With this crank the top ends of the standards 35, can be vibrated to and from the cylinder. Between said standards are pivotally mounted a rubber platen 36, rollers 38 and 41, and a spool 37, carrying printing paper .57, saidspool being 'ournals of the roller 41, springs 53, (one' mounted with the same means as the in delible' ribbon spools. Oblong openings 72, are made in the said standards 'to receive the ing on the opposite side) are affixed to the standards with screws 55, one end of said springs are placed under the journals aforesaid and the. other behind the screw 54, which also holds the end of a spring 52, the-object of s ring pressing the roller 41,

against the re er 38, is to keep the printing paper from slipping. A curved member 59, for guiding the paper around the roller 41,

. is soldered to one of the standards and extends laterally xsomewhat beyond the standards and is convenient for tearing oil a portion of the free end of the paper. A table 73, having a right angle bend as indicated by the dotted lines 39, is affixed to one of the plates 35, with screws 40, the function of said plate is to support the printing paper when it is desired to write or stamp characters on said paper. A knob 43, and ratchet wheel 42, is rigidly aflixed to the end of the arbor on which the roller 38, is mounted.

A dog 44, having its free end curved is pivotally joined to the angle-plate 33, with .a screw'45, the free end of said dog engages the ratchet wheel 42, and the spring .52, holds it in engagement therewith. It

will be seen that when the free ends of the standards are moved toward the type the dog will move into the next notch below and when the spring 58, brings the standards to their normal positionthe ratchet wheel will be rotated one notch, moving the paper 57,

- the ribbon in the opposite direction the dogs are reversed and dog 47, is put out of commission by placing it on the pin 46, and 48,

engages wheel 24, the dogs receiving their movement by the vibration of the standards 35. The charactersplaced upon the type-- blocks and the keys are the same.

' Having described the construction and arrangement of parts vI will now describe its modus operandz'.

Having afiixed the desired characters to be printed upon the keys and type blocks (there being a key for each type-block and a tooth 56, for each block) and it is wanted to print 257 52 the key, bearing said nu-' merals is pressed down and the free end of the bar 11, is raised up off the rod 15, and contacts the cylinder section 4, and the knob 8, is turned and the tooth opposite the type bar bearing the aforesaid numerals enters the V shaped notch 12, and stops the rotation of the cylinder and locates the aforesaid type block exactly right to receive the print, while the key is still held down the crank 51, is moved and the platen 36, strikes the indelible ribbon against the type and makes a print on the paper 57, the crank and the key is then released and the spring 58,- returns the standards 35,

to their normal position and the free end,

of the bar 11, having dropped down on the rod 15, and coincident therewith the dog 44, rotates the ratchet wheel and printing paper one step and the dog 7 3 prevents adverse rotation and the dog 47 rotates the ratchet wheel 25, one step which moves the ribbon, meantime the print 25752 is brought up into full view of the operator for inspection. Each type-block on the cylinder is presented to the platen or roller 36, in exactly the same way. When the key is pressed down it makes no difference which way the cylinder is turned. The'month, day and year can be stamped upon the printing paper resting on the table 73 which makes the beginning of the days work.

From the foregoing it will be observed that I have produced a simple, compact and sire to limit myself to the structural details defined but reserve the right to effect such hanges,modifications and variations as may comprehended within the scope of the 'l protection prayed. I
