Referring to the drawings in detail this improved stencilling machine comprises a frame designated generally l6 which includes a head H from opposite ends of which extend spaced parallel end walls i8 and H31, g

Projecting .from the head I! in a direction opposite the end walls 58 and 18 is a handle 20, and extending laterall from the handle 20 adjacent the end remote from the head ll ar oppositely extending finger grips 2! which are adapted to be grasped in the hand of the user to facilitate the manip la'tion of the stencilling machine; Removably supported on the front and rear sides respectively of the frame are cover plates 22 and 23 which form in conjunction with the end walls :8 and is a hollow chamber 24 in for adjusting the stencilbe more fully hereinafter plan view of the stencilling strips or ribbons to described is housed. Extending through the midway between the upper head I! and the handle 29 is an axial opening 25 and projecting into the chamber 24 from the underside of the head I! is a guide and supporting sleeve 25 which terminates substantially and lower ends'of the chamber. Extending radially through the sleeve 26 adjacent the junction with the head H is an internally screw threaded opening 2"! for the reception 'of a guide screw 28 the purpose of which'will be more fully hereinafter explained.

Mounted for longitudinal movement in the axial opening 25 is a plunger 28 carrying at one enda head 38 and surrounding the plunger 29'between the head 30 and the upper end'of the handle Zllfis a compression coil spring 3| which yieldingly holds the plunger in retracted position. Fixed to the end of the plunger 28 opposite the head 36 to work within the chamoer 24 is a cross piece 32 carrying a cushion 33 which is enclosed in a flexible cover 3d which together with the cushion and cross piece forms an ink pad. Extending longitudinally of the plunger '29 is a groove 35 into which the inner end of the screw 28 extends, in order to hold the plunger 29 against rotation and at the same time permit it to move longitudinally in the opening 25.

Extending longitudinally through the charm ber 24 adjacent the front and back wallsthereof are bars 3'! and 38 respectively which serve to bridge the gap between the end walls 58 and i9 and hold said walls in spaced parallel relation.

Mounted in the end walls for rotation about a horizontal axis directly above the longitudinal bars? is a shaft 39 which projects through the .end wall it and is fitted with v.a knurled thumb .piece' lll by which rotation of the: shaft 39 may be manually controlled. 'Journ'aled in the walls [8 and 19 to rotate about a horizontal axis directly above. the bar 33 is'a shaft 4!, andfixe'd tothe shaft39- adjacent the wall i9 is aspur gear "42. A; similar spur gear 43 is'fixed to the shaft M to rotate in the plane of rotation of the spur :gear 42, and extending longitudinally through the chamber 2-4 in spaced parallel relation are shafts 44, 453ml 45 upon whicha train of meshing .gears designated. generally 47' are mounted to rotate. The endmost gears in the train 4'! mesh with-the gears42 and43, so that when the shaft -39 is rotated the shaft 4! will rotatein unison therewith. Fixed to the shaft 39 adjacent the gear 42 is one end of a stencil strip or ribbon 48,

the opposite end of which is fixed to the shaft 4!. It will thus be seen that when the shaft 39 is rotated the strip or ribbon 48 maybe wound upon or payed-out, and when thestrip or ribbon is being wound upon the shaft 39. itw'ill bepayed out" from the shaft 4| and vice versa. This ribbon or strip 48 is provided with a longitudinal row of perforations 49 which preferably take'the form of numerals with their vertical axes aligning longitudinally with the longitudinal axis ofthe ribbon .or strip.

Mounted for rotation in the walls 3 and i9 and extending longitudinally of the chamber 24 in parallel spaced'relationwith the shaft 4! is a shaft 58, one end of which extends through the end wall it and has fixed thereto-a knurled thumbpiece 5! by means of which the shaft. may be rotated. A similar shaft 52 is mounted .to rotate-about a horizontal axis in spaced relation to theshaft 39 within the chamber 2-4near the front cover of the chamber and fixed tothe shaft 59'and to'the shaft 52 respectively are toothed gears% and 54 respectively. :These gears 53and 54 are fixed to the shafts 5i! and 52 intermediate their'ends to rotate in a plane iii-spaced relation to the plane of rotation of the gears 42 and 43 and mounted on the shafts M, 45 and A? for "rotation in the plane of r-otationof thev gears 53 and 5 are meshing gears forming'a. gear train designated generally 55, the gears-atopposite ends of which have mesh engagement with the gears '53 and disc that when the thumb piece 5! is rotated both shafts 55] and 52 will be moved in unison. Fixed to the shaft 56, is one .end .of a

may be wound or unwound as the case may be with relation to the respective shafts 50 and 52. Like the strip or ribbon 49, the strip or ribbon 56 is provided with a longitudinal row of longitudinally spaced perforations 51 which preferably take the form of numerals, the longitudinal axes of. which lie coincident with the longitudinal "axis of the strip56.

Mounted for rotation about the shafts 39 and 4| respectively adjacent the end wall [8 are sleeves 5'! and 58 respectively. The end of the .sleeveLEB projects through the wall I8 to the exteriorof the chamber 24 and secured to said sleeve iSTa knurled thumb piece 59 by means of .a gear train designatedgenerally 252, the gears at'opposite ends of which mesh with the gears 65. and 6| so thatwhen the'thumb piece '55 is retated the sleeves -b'land58 will rotate in unison therewith. A stencil ribbon or strip $3 has one end secured to the sleeve-5? while its opposite end is secured to the sleeve 58 so that when the-thumb piece '59 is rotated the ribbon will be wound or unwound from one'or'the other of the sleeves. Like the ribbons or strips previously described the ribbon or strip 63 is provided-with a longitudinal row of longitudinally spaced perforations 64 which'preferably take the form of numerals, the longitudinal axes of which coincide with the iongitudinal axis of the ribbon or strip b3. It will be understood of course that the ribbons orstrips are led downwardly across the face of the ink pad'formedby the cushiondS and'the cover 34 so'thatwhen'the perforations 49, 51 and M are aligned across the face of the ink pad and pressure applied to the head 30, the ink on the ink pad'will'form a group of numerals on a surface to be marked.

In order properly to guide the ribbons across the face of the ink pad each end wall #8 and i9 is provided'on itsbottom edge'with a pair of outwardly extending angle bracketsfi' which project in opposite directions 'awayfrom the head 39 forming the ink pad and extending between the brackets at opposite ends of the frame'are closely spaced parallel'bars55 between which the ribbons or strips areguided.

In'order' to'confine the sten'cilling operation tca'limitedarea of the surface to be marked, Iprovide af'shield designated generally it which comprises'a rectangulariframe 6? adapted to be 'fitted around the lower "openend of the frame "hand fixed in'the frame'fi'l is a fiexible shield comprising a bottom 68 of substantially rectangular form. having upwardly extending side and end walls 69 forming a substantially boxlike structure. This shield is preferably'formed of rubber or a similar flexible material arid the bottom 68 is formed with a'w-indow iii through which thestencil strips or. ribbons are'exposed in the vicinity of'the ink, pad. @Theframe E? is provided at spaced intervals with openingsfoi the receptionof screws H by' means of which it may be fixed to the open end ofthe frame it as will be readily understood upon reference to the drawings.

In use it will be understood that the proper numerals may be bronght into alignment'across the face of the inkpadso as to be exposed through the window l0 'bymanipulating the thumb pieces 40, and 59. The user then grips the bars 2| with the head 30 resting in the palm of the hand and by placing the shield 66 over the items to be marked as illustrated in Figures 1, 2 and 3, and exerting pressure on the head 39, the ink pad will be moved against the strips or ribbons 48, 56 and 63 so as to advance them against the surface to be marked and by reason of the openings 49, 51 and '64 in the respective strips or ribbons it will be evident that the ink contained by the ink pad will be impressed against the item to be marked, leaving a mark thereon conforming to the shapes of the perforations. By forming the perforations in the nature of numerals it is obvious that the device may be used for pricing items and for similar operations.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
