useful Improvements in Copy-Holding and Liiielndicating Devices, lowin isa specification.

This invention relates to oilice appliances of which the tol- .and has particular reference to copy holding machines wherein the line to be copied is indicated in a manner such that the operator may readily `check his work as the saine progresses. y

The primary object oic this invention is to provide a copy holding and line indicating ineanswhich is readily adapted to be used with statements having any length or line spacing.

Another object of this invention is to provide the copy holding means with a line spacing arrangement which is at all `times positive `in its action as well as easily operated, also inexpensive to ,constructV and maintain. i

lVith the above and many other objects in view which will be readily apparent as the nature ot' the invention is Vbetter understood,

the same consists in the novel construction, combination and arrangement of parts as will be hereinafter fully pointed out, illustrated and claimed.

It, 'willk be quite readily understood by those skilled in the art to which this inveiition belongs, ythat the saine yis susceptible of some struc-tural change or modification without departing from the' spirit or scope of the invention, but a preferred and practical embodiment ot the invention is shown inthe accompanying drawings in whicli- Figure 1 shows a front elevational view of the present invention.

Fig. 2 shows anend elevation of the parts shown in Fig. 1, showing the drinn and the means used for rotating and locking the same.

Fig. 3 shows in detail the drinn rotating and locking elements.

Fig. lshows the tension device employed to return the operators pedal to its initial position, after the operator has pressed the saine down in order to rotate the cylinder.

Similar reference numerals refer to simi,- lar parts throughout the several figures of the drawings.

In the construction of this device I have endeavored to eliminate all unnecessary elei ments, such as those that add to the initial cost and perform no independentand useful' function and kto this end the present invention consists essentially ot a base board designated by the numeral. 10, having attached thereto` two cylinder supporting brackets 11 and 12, each of which preferably take a triangular 'forni with inwardly eX- tending webs 13, which together with the integral face piece` 14 gives the requiredr rigidity as well aslightness to the construction. i

At the apex ot each triangular bracket the faces 14 terminate in a circular basev 15, which is perforated as shown at 16, for the purpose of formingy a journal bearing for a rod 17 which carries avr rotatable druinlS, around whichv the sheet to be copied from is placed. j v f The drinn 18 is preferably formed fromr sheet metal, of asuitable thickness, which is secured to annular rings 19, positioned at either end, as shown in Fig. 1 of the draw-` ings.

The drinn 18 is further provided with a sheet holding device 20, having the ends turned upwardly, inwardly, downwardly and outwardly such, as to passthrough a suitably positioned opening 21 in the drum `1S and to enter an opening' 22 inthe web 23 where the same is fulcrumed, as shown in Fig. 2 of the drawings.

For the purpose of producing a suitable-y tension on the rod 2O there is provided a y spring 211, the end 25 of which is secured to the drum 18 through suitable fasteningV means 26, while the free end 27 engages the `inwardly extendingportion rof the rod-20,4 and serves to keep the same drawn down on the surface of the drum.

For the ,purpose of rotating the drunilS the required amount for single line spacing there is provided a `drum rotating device, consisting essentially of a lever 28, which is adapt-ed to be fulcruined at 29, and havingV provision at the end 30 for atta-ching thereto a vertical rod v31, the upper-end 32 ofv which is adapted to be secured to a lever 33, which'is fiilcrumed on the rod 17 as shown in Fig. 1 ot' the drawings.

The lever 33 carries a drum rotating element 34, which consists of a segment, fiilcrumedat 35, and provided with a perfo- ,shown in Fig. vious trom the construction shown in Fig. 'Y

rated lug 36 through which 'isfadapted pass a rod 37 yfulcruined at 3S which is provided with a tension spring 39 Jior keeping the surface 40 of the segni ent in contact with the surface 4:1 ot the annular ring 19 as 2 ot the drawings. It is ob that any downward movement of the-lever Q'Swill cause an upward movement oi the.

lever 33 and likewise a rotation of 'the drum 18.

For the purpose ot keeping the drum :troni` rotatingcounter clocln'vise there isv provided a drum locking'device Vwhich is shown more in detail Vin Fig. 3 and consists prim( rily of a spring actuated lever Ll2 having a notch f3 cut therein for the purpose ot engaging the inside and ontsideperiphery of the annular ring 19, tending` in a very practical way to arrest any baclzwardinovement oi the drum .18. From Fig. 3 it will be noticed that anyclockwise motion of the druni v-is not prohibited by the locking element but at once any counter clockwise rotation is arrested. For the purpose of hee aine` the lever L2 in its bro :ier osition,

there is provided a spring LA, which is adapted to bev coiled around the Yulcrum post 45, having one free endrestinglupon a stationary lug L6 while the other rests against the lever l2 holding the same in position as shown in Fig. ofthe drawings.

For the purpose of 'keeping the proper tension on the .drum rotating device there is provided a tension adjusting; mechanism as shown in Fig'. of the drawings which censists primarily of a. helical spring it?, which is adapted to abut against the ledge 1l-.6 withV one end while the'otherend is at the rod' 3l, which has associated therewith a movable bracket 48 and a wingnut d?) for clamping` the 'bracket in any desired porA sition. f

The line indicating,` device designated in its entireth by the numeral 5,0 consists essentially of a plateV 51' which is adapted Vto rest against the faceY of the drum 18. The plate 5l is fulcrunied on a rod 52, and co-` acting therewith isl a tension spring, 53

which 'serves to lkeep the plate pressed tacliel to against'the druin so as to lrinly hold the paper in its properplace.

The rod 52 is fulcruined on the brackets ateither 'end vat 54.' VCoperating` with a short horizontal section 55 of the road 52 there .is spring 56 adapted to be heldl in place lby the screws 57, asshown in Fig. 2

eye, a rod loosely connected with the operat'- ling` lever and slidably engaging said eye oi the cam and carrying spring tensioning means therewith, an operators lever pivotally mounted in the lower part of the iii-aine,

land a. spring` tensioned rod connecting the tree end ot' the operators lever and the main operating lever, said rod having,I Va vertical guiding engagement with the ltrame.V h

2. A copy holding and line indicating' device consisting of a traine, a co1 y holding` drinn rotatably journaled in the traine and presenting' a lange at one end, a manually actuated device for engaging with said flange of the drinn to advance thela-tter in one direction only, and means carried by the 'frame for preventing backward rotation of the drum consistino of a sni"in "'tenV jsioned lever element having a notch in one edge thereotlv for engaging `overthe laiige of the drum7 the sidesfof said notch lying in a Vplane inteiecting` the circumference of the drum.V
