TYPE-WRITING MACHINE.
Specification of Letters Patent.
Patented Apr. 50, 1912.
Application filed October 27, 1911. Serial No. 657,146.
To all whom it may concern:
Be it known that I, Homer L. Woonwnnn, a citizen of the United States, and resident of the city of Washington, District of C luinbia, have invented certain new and useful Improvements in Type -VVriting Machines, of which the following is a specification.
My invention relates to type writing machines and more particularly to the paper fingers and associated paper feed devices of such machines.
The principal. object of my invention is to make sa-id paper fingers more convenient in use. Some forms of paper guiding and feeding devices on typewriters as heretofore constructed, comprisea paper finger that is spring-pressed against the margin of the-' paper about at and above the writing line and in addition to this paper finger there is also a small rubber-covered roller which is independently spring pressed against the paper. Each of these devices is capable of being lifted away from the platen to release the paper and iii-the Monarch machine, for example, the roller is adapted to be retained in its released position but the paperlfinger.
is not provided with any such retaining means. When making on one of these machines two copies with an interposed carbon sheet and it is desired to make a correction on the carbon copy, the .paper fingers are slid longitudinally of the platen off the paper so as to allow the fipst copy and carbon to be folded forward and thus to expose the carbon copy for correction. hen the paper is restored to position the paper fingers have to be slid back longitudinally of the platen again to cover the paper. In this operation said paper'finger is likely to catch on the edge of the paper and it is necessary sometimes to hold said guide plate up by hand, so that the operation requires two hands to perform it. In this'respect' and in some others, the paper fingers aremade more convenient by my invention.
To the above and other ends my invention consists in certain features of construction and combinations and arrangements of parts, all of which will be fully set forth herein-and particularly pointed out in the claims.
In the 'accompanylng drawings,
all of,
which are on an enlarged scale, Figure l is a view in fore-and-aft vertical section of part of a Monarch typewriter including one of the pa er fingers and associated parts and the platen and showing the parts in normal position. Fig. 2 is an end view of the same, partly broken away, and showing the roller elevated to a middle position. Fig. 3 is a view similar to Fig. 2 but showing the roller elevated to a higher position and the paper finger held away from the platen. Fig. 4 is a top plan view of the paper finger and associated devices and par-t of the rod on which they are mounted.
The Monarch typewriter carriage in cludes two end bars or brackets 1 in which is journ aled the shaft or axle 2 of, the platen.
3. The paper is fed around the platen mainly by the co'iiperation with said platen of main feed rollers 4 and 5 which feed the paper to the printing line on the front face of the platen. After passing the printing point the paper is controlled by the paper feeding and guiding-devices presently to be described. Each of the brackets 1 has an upright extension 6, which extensions are connected by a frame rod 7 ext-ending parallel with the platen for the full length thereof and above said platen and somewhat to the rear of' 'the axle 2.- The machine is usually equipped with two paper controlling devices or mechanisms, each comprising a sleeve 8 slidably mounted on the rod 7 butpivot-pin 12 passes. At its forward end said.
roller-carrier is formed with a projection 14,- formed to constitute a'handle or thumb-piece for moving the carrier up and down away from and toward the platen. It is the righthand paper controlling devicethat is shown in the drawings. Each of the carriers 11 has F'projecting therefrom toward themiddle of the machine a stud on which is journaled the sleeve-like hub of a roller 16, which roller is usually covered with rubber and is retained in position on the stud by a screw 17. The roller-frame or carrier 11 is yieldinglv held'in either one of a plurality of positions lay a spring-pressed plunger 18 COHSlSlJIlg of a splndle or pin w1th a broad.
flat head, said pin being seated in a hole 19 in the carrier'll. Said hole is made of two diameters, as shown in Fig. 1, to accommo date a compression spring. 20 which presses the fiat head of the plunger against the flattencd faces of the end of the arm 10. lathe present case 'Iohave shown. three such flattened faces 21, 22 and 23. The plunger 18 normally cooperates with the face21, as
shown inF'ig. 1, where it will be seen that thetension of the spring. 20 is exerted to press the roller 16 against the laten. If
the frame 11. he moved up to t e position.
shown in Fig. 2, the plunger 18 cooperates with the middle face 22 and holds the roller away from the platen. Said frame can also he moved up to the higher position shown in Fig. 3 where it will he retained by the action of the plunger against the face 23.
The paper controlling device also includes a paper finger 2 1 of well-known construc tion, said finger being usually constructed of a piece of thin spring sheet steel riveted to a part 25 which has bent up therefrom ears 26, which ears are pivoted to the arm .10 at 2?. "A spring 28 is compressed between the arm 25 and the arm 10 to-press the fingel" 2% vieldingl'y against-the platen. spring 28 is seated in a hole in the arm '10, as indicated in Fig. 1.
My invent-ion comprises means for automatically lifting the paper finger 24. away from the platen, as shown in Fig. 3, when the frame 11 is elevated to its Fig. 3 position,
and said means is preferably of such charac-' as will be understood from Figs. 3 and 4-,
and cams said paper finger upward again t the tension of the spring; 28, The parts w1ll he held 1n the position shown n Fig. 3 by the spring-pressed plunger 18 and both theroller and the paper finger will then be free. of the paper on the platen and can he slid into position to cover the margin of said paper with one hand and without danger of wrinkling or tearing the paper. After the independently of the paper ling The the-finger 24, in order to adjust the paper in the machine and enable the paper finger to slide more freely; and forthis reason I deem it preferable to provide for the middle position of the roller 16. by making the arm 10 with said middle facet means can be provided for retaining the frame 11 in either one of twothree positions.
It willhe noted that th it will of course he understood that other forms of lost motion connection can he suhstituted for the one shown. It will also he lllltltll'StOOtl that the invention is capable of modification. in other respects to adapt to other stvles of paper finger thanthe specific one shoe a. In factthe precise construction illustrated,
is merely the adaptation of the invention to the particular form of paper feed I now employed in the lllonarch and which ;ma v he found more ill. forth in the U Patent No. g ed May 18th, 1909 to G. A. Eleih. it will he perceived that in order to adapt my inrea 'tion to said paper feed devices, the latter have been modified but slightly.
What I claim as new and desire to secur by Letters Patent, is:
1. In a typewriting' machine,. the comhination with a plate'mof a paper feed mecha nism for cooperation with said platen above the writing line and comprising two paper controlling devices cooperating with the paper independently, means for lifting one of said devices off the paper and retaining; it in released position and a lost motion connection to tlieotherpaper controlling device for lifting said other paper controlling device off the'paper and retaining it in released position.
