United s, and resident .of the borough of Manhattan. city of New 5 York, in-the county of New York and State of New York, have invented certain new 'and useful Improvements in TypeNVriting ilrlachines, of which the following is a specific'ation.

The paper feed mechanism is mounted in 'i To the above and other ends my invention part on a transverse frame rod 8 which at AU-consists in certain features of construction. its ends is rigidly secured in the brn k t 3 '15 and [combinations "and arrangements of behind the platen. parts, all. of which will be fully set forth A. main fee-d roller 10 has an axle 1 1, the -lii3l6ill end particularly pointed out in the ends of which are ournaled in the free ends l i 'of arms 12, \'l1ich arms are pivoted on the 5- V, In the. accompanying drawings, Figure 1 rod Each of the arms. 12 forms part or" .36 --is a fore and aft vertical sectional'viow of a lever of the first order, which lever also the. carriage of a typewriting machine how" has an upwardly extending arm-l3, on which a. ing nyfinvention embodied therein and sets a contractile spring 14, which spring i shoi ringthe. parts in normal position.

Said collar 16 is apronund paper finger devices in paper reshouldered in order to secure .the arm 15 leasing position. It will be seen that Figs. thereto and it has a reduced part that pro jects toward the middle of the machine beyond said arm 15 and into position to prevent motion of the levers 12, 13 toward the end of the carriage. In order to regulate 2 and 3 together show the paper feed mechanism inreleasing position. Fig. 4 is a rear elevation. Fig. 5 is u fragmentary front elevation of parts of the mechanism.

fe -ail with grooves 2 in its front I have provided a paper apron or de hector 20 lying bengath the platen and curved into a t of general. conformity to curr the" platen as shown in Figs 1 his paper apron or deflector is or bodily mption in a general fore direction and suitable means are provid d for guiding this motion of the forward part of said paper apron in a general front and back direction but preferably in a. direction forward and more or less in ciined downward and back at a correspond- .li ation upward so that when the iron is drawn toward the rear its rt moves rearward and more or and is pressed against the surplaten at a suitable distance below Killing line, as will be understood by refers-n to Fig. 1.- This guiding means can, for of the purposes of my inventicn, be Q1 any suitable specific construction. in the present instance the extreme forward part of the paper apron is prolonged to the brackets or end pieces 3 where it is formed with bent off at right angles, and approximately contacting with the inner surfaitaazs of said brackets. As best shown in Fig. 3., each of these cars is formed with an slot 22, which slot extends in a ward at an upward inclination and in which is a rod 23 supported by the end bracket 3 so that said rod and said slot guide the forward part of the paper apron in the manner which has been described.

The rearedge of the paper apron 20 falls a little short of reaching to the main feed roller 10 throughout the greatr part of the length of said paper apron but at its ends said apron formed with prolongations 2+1, best shown in Figs. 3 and 4, and each of said prolongations has an ear 25 bent off therefrom. A contractile spring 26 is connected to each of the ears 25 and the rear end of said spring is connected with an arm 27 rigidlymounted on the rod 8 to which 'it is secured by a set screw 28. It will be perceived that thesprings 26 exert their tension on the paper apron in a direction that is substantiallya direct rearward pull. In the present instance and preferably the springs 26 constitute the sole support for the rear part of the" paper apron. It will be seen that this leaves said paper apron free to be depressed at'itsrear part forthe insertion of a thick bunch of papers.

The paper feed release mechanism comprises a handle 30 consisting of a lover arm rigidly mounted on a rock shaft 31-wli1ch at its ends is suitably pivoted in the brackets 3 and which passes across the carriage just above the rpller 10 and in front of the arms 12. In the present instance the handle or lever arm 30 consists of a strip of sheet metal so bent as to pass under the rod 8 and thence upward into position for convenient bodily toward the front.

forward at a downward inclinamanipulation. The rock shaft 31 normally occupies the position shown in Fig. l and it is operated to release the paper by pushingtension of the springs 1% and release the feed roller 10, as shown in Fig. 2. The

arms 33 occupy the positions shown in Figs. 3 and l where it will be seen that they extend down behind the extreme rear edge of the rearwardly projecting parts 24 of the paper apron. The construction is such that when the handle 30 is operated as shown in Fig. 3 these arms more toward the front ofthe machine and push the paper apron Its motion is guided by the slots 22 and rods 23 soas to move the forward part of the paper apron away from the platen as shown in Fig. 3. It will of course be understood that other means can be provided for moving the paper apron bodily toward the front.

I provide a pair of marginal guiding devices for cooperation with the margins of the paper at and above the writing line, and means for controlling said guiding devices. Each of said guiding devices comprises a feed roller 34 having trunnions 35 journaled in the forked upper end of an arm or paper finger or paper guide 36, said finger or guide consisting of a strip of sheet metal which at its lower end is widened out and folded approximately into a square tube as shown in Figs. 1 and 5 at 37, and each of said sheet metal arms has also formed as part thereof a forwardly projecting finger piece 38. The square barrel, hub or sleeve 37 fits on a square shaft, which shaft in'the present instance consists of the rod 23 that serves also as a guide for the ears 21 of the paper apron. There are two of these rods or shafts 23 and they are arranged end to end, their inner ends being cylindrical and of reduced diameter, as shown in Figs. 1 and 5, and journaled in' a sheet metal bracket 40 secured to the paper apron 20 at aboutthe middle thereof. Each of these shafts 23 is journaled in and passes through one of the end pieces or brackets 3 and on the outer. end of each shaft there is rigidly mounted an arm 41 constituting a finger piece for turning the shaft: and said arm also has connected thereto a spring 42 the rear end of which is connected to a pin {13 projecting from the bracket 3. This spring exerts its tensionto i or margin guide can then be on thearm or finger piece al this spring tens. smn can be relieved, and the paper finger adjusted longitudin'ally of the rod 723 with ease.

The arm 41, spring 42, shaft 23 and the paper guiding and feeding devices 36 and 3% are all similar in details of construction to the corresponding parts'now in use on the Remington typewriter. I therefore do not claim anything new in the Specific construction of these parts, and as far as some of the features of my invention are concerned, they may be constructed otherwise than as shown. I do, however, claim the cooperation of said parts with the paper apron 20 in the respects that said shafts are associated with said'paper apron at the outer ends .thereof'and also that said shafts are connected to and supported by the paper apron at the middle of the machine and also, as will presently be described more in detail, '11 the respect that the marginal guide devices and the rod or rods on which they are mounted ale moved toward. and from the platen by and in'unison with the paper apron, in one instance to cause the parts to cooperate with the paper and in the other instance to cause said parts to release the pa er.

- s will be noted in Fig. 1 that the arm 36 lies just in front of the front edge of the aper apron 20 and when said paper apron i;- moved toward the front of the machine its in Fig. 3, this arm is also moved toward the front of the machine, releasing the pres- ;sure of the roller 34 on the paper. It will noted that when the marginal guide de vices are adjusted near the ends of the platen, that the rods 23 on which they are mounted partake in but a slight degree of the motion of the paper apron in the releas- {ng operation. When the marginal paper ldes are thus adjusted there isbut little ggxure of the rods 23 due to the pressure on said devices because the devices are then near the fixed pivots of the rods. When, however, said devices are adjusted near the middle of the platen to cooperate with a card or narrow piece of paper, then the rods themselves more outward with the paper apron. Ineither case both the marginal guides and the rods on which they aresupport/ed move with the paper apron. in the releasing operation and said margipal guides are themselves moved to releasing position by said paper apron.

I provide a paper table at the rear side of'the platen, said paper tahle consisting of a pie of sheet metal of suitable form havingfirveted to the rear face thereof two knuckles 45, each constituting one member of a hinge. The members fl5 cons st each of a strip of sheet metal having its lower end rolled into a cylinder 46 into which PZOJGCtS a min 41? constituting the other member of the hinge, Said pm 47 is partofasheet as a'hlank and metal bracket stamped out folded or bent into the". .form"showjn in the drawing; 'L aidblank is formed waa two branches or arms 48' which are-bent back into parallelism and in planes at right angles to the arms 47 and perforated and placed upon the rod 8. The arms or ears" 48 are connected by a yoke part throughwhichis threaded a set screwed: which screwat its, inner end engages'a flattened part 51 of the rod 8 so as to secure the entire bracket againsteither sliding or turning'on' said 1 0d. Said bracket is also formed with another arm 52 which extends upward and rearward and serves as a prop or rest to supportthe upper part of the. paper table and to limit the extent to which said paper table. can tiirn about its hinges. Just above one or both of the arms 52 a lug or? pin '53projcts toward the rear from the paper table and the parts are so adjusted that they have to be sprung a little in order toget the arm 52 caught under this lug 53. The result is that the upper end of the arm cooperating with the notch between the fiat surface of the paper table and the lug 53, acts as a sort of detent to prevent accidental turning-of the paper table toward the'front of the machine. Said paper table can, however, be turned toward the front by the exertion of a littleforce to spring the arm out from the notch. Itis desirable to have the papertable hinged in this way because there are some devices underneath it that may occasionally require attention. The paper table can be removed at any time by loosening one of the screws 50 and sliding the stationary hinge-member toward the middle of the machine, thus piLl1- ing the pin 47 out of the knuckle 45.

\"arious changes can be made in the details of construction and arrangement without departing from my invention.
