F. M. AIMES DEMONSTRATING MACHINE Filed April 9, 1936 ATTORN Patented Oct. 12, 1937 PATENT OFFICE DEMONSTRATING MACHINE Francis M. Aimes, New York, N. Y., assignor to Inkograph 00., Inc., New York, N. Y., a corporation of New York Application April 9, 1936, Serial No. 73,476

20 Claims.

This invention relates to machines for use in displaying as well as demonstrating the use of certain articles of manufacture, and particularly writing implements, such as pens, pencils, fountain pens and the like; and the object of the invention is to provide a machine of the class described which is of economical construction whereby the cost of producing the same will be reduced to a minimum, thereby facilitating extensive use of machines of the class under consideration; a further object being to provide an article or implement supporting arm, with means for moving said arm forwardly and backwardly, laterally as well as vertically with respect to a writing, marking or display surface, whereby an elliptical or substantially elliptical mark may be made on a writing surface or a sheet disposed on said surface in each cycle of operation of the machine; a further object being to provide means for supporting a roll of paper or other material upon which the marking is to be arranged, with means for intermittently feeding the strip or ribbon of such material through the machine so as to space the successive markings longitudinally thereof; a further object being to provide quickly attachable and detachable means for supporting and guiding the marking strip or ribbon in its movement through the machine; a still further object being to provide means for intermittently rotating the article or implement supporting means in the arm of the machine so as to eliminate the uneven wear upon the marking pen or tip of the implement; and with these and other objects in view, the invention consists in a ma- 5 chine of the class specified, which is simple and economical in construction, efiicient in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following 40 specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which:

Fig. l is a longitudinal sectional view through the machine, with parts of the construction shown in a different position in dot and dash lines.

Fig. 2 is a plan view looking in the direction of the arrows 2--2 of Fig. 1, with parts of the construction broken away; and,

Fig. 3 is a partial section on the line 3-3 of Fig. 1.

In practice, I provide a box-shaped casing or housing 5 which is open at the bqttom, and one otherwise secured to the side walls 6 thereof is end consists of side walls 6 having outwardly extending bottom flanges 'l which are preferably apertured to facilitate mounting upon a suitable support. The upper edges of the side walls 6 are joined by a transverse top wall 8 which is integral therewith, in other words, the entire housing is stamped from a single sheet of material. The top wall 8 is downwardly inclined as clearly seen in Fig. 1 of the drawing, and mounted in the front or narrow end portion of the housing is a closure panel or shell 9 which provides a finish for the front end of the machine.

Mounted within the housing 5 and welded or a transverse supporting plate I0 upon which a conventional motor reduction gear or transmission housing H is supported. An electric motor diagrammatically illustrated at l2 has its shaft l3 coupled with the mechanisms of the housing H so as to actuate a drive shaft l4 projecting upwardly from the housing H.

Coupled with the shaft l4 through a yokeshaped coupling I 5 is a crank shaft l6 which extends upwardly through bearings I! in the top wall 8 of the housing and is provided at its upper end with a crank arm l8. Secured to the shaft I 6 is a sleeve Hi to which is secured a radially extending arm 20 having an anti-friction roller 2| which is adapted, in each cycle of revolution 30 of the shaft l6, to strike the flanged end 22 of a long pawl strip 23. The strip 23 is supported and guided upon the under surface of the top wall 8 by a grooved ring 24 operated in an elongated slot 25 in the pawl 23, and is further guided against lateral displacement by a pin 26 secured to the top wall 8 and operating in another elongated aperture 21 in the pawl 23. The forward end of the pawl strip 23 is offset to form the pawl proper 23a which is mounted directly over and adapted to engage a ratchet 28 secured to a transverse shaft 29 mounted in the front corner portion of the housing.

Secured to the shaft 29 is a drive wheel or 'roller 30 which extends upwardly through an opening 3| formed in the top wall 8 of the housing as clearly seen in Fig. 1 of the drawing. A spring finger 32 is employed to engage the ratchet 28 to retain the same against backward movement. An adjustable screw 33 is employed to regulate the tension of the spring finger 32 upon the ratchet. Stamped from the pawl strip 23 is a spring supporting member 34 with which one end of a coil spring 35 is attached, the other end of said spring being coupled with the transverse support Hl through a link rod 36. The spring 35 serves to support the pawl strip 23 in a rearwardly extended position and to also aid gravity in supporting the pawl proper 23a in engagement with the ratchet 28.

The roller 22 advances the strip 23 forwardly against the action of the spring 35, this movement being slight and sufficient to feed the paper or other strip or ribbon 3'! forwardly through the machine. The supply of the sheet 3'! which forms the rotating or marking surface comes from a roll 31a mounted upon a removable pin 38 which is supported in an upwardly extending yoke-shaped frame 39 welded or otherwise secured to the top plate 8 of the housing. Secured to the under side of the top or crosshead of the frame 39 is a longitudinally extending plate it, to the forward end of which is secured an upwardly extending guide pin 4|. An anti-frictional roller 42 is mounted in connection with the rear or angularly extending end of said plate.

' The plate 40 also includes a bearing 43 for the upper end portion of a crank shaft it. At the free end portion of the crank arm i8 is an upwardly extending pin or rivet 44 on which is mounted a roller 35 which operates in a yokeshaped support 46 pivoted to a companion and inverted yoke-shaped support 4'! as seen at (18. The support M is secured to an implement or tool supporting arm A9. The pivot 48 permits vertical swinging movement of the arm from the position shown in full lines in Fig. 1 to that indicated in dotted lines in said figure in the operation of the machine. The arm 49 is in the form of an elongated strip, the forward end portion 56 of which is curved downwardly, and itsfree end is bent at right angles to-form a support 5i fora bushing 52 in which is rotatably mounted a sleeve 53 which forms a tool or implement supporting member, which in the construction shown, is internally threaded at its lower end as indicated at 54 to receive the threaded portion 55 on a fountain pen 53.

The fountain pen 55 in the construction shown is of the Styleograph type and requires intermittent rotation to avoid the possibility of wearing the fine rod-like point flat at one side. For this purpose, a ratchet wheel 51 is secured to the sleeve 53. This wheel isadapted to engage a projecting finger 58 secured to the frame 39 in the swinging movement of the arm 39 to rotate the sleeve 53 and pin 56 a partial revolution in each cycle of movement imparted to the arm. The arm 49 including the curved portion 50 thereof has an elongated aperture 59 in which the pin 4} operates.

The pin 4i forms a pivot around which the arm swings in the movement imparted thereto by the crank l8. The point of the pen will travel through a substantially elliptical path and will 7 scribe or mark upon thewriting sheet or surface 37, a series of open elliptical marks as partially indicated at. 60 in Fig. 2.0f the drawing. The ends ofthe. markings 60 terminate at the points 69a by; reason of the fact that the pen is raised from the surface 37, which result is accomplished by the engagement of an upwardly ending flange 6| on the free end of the downwardly and forwardly extending rear portion 62 of the arm 49,

with the roller 42, as is indicated in dotted lines in Fig. lof the drawing. The transverse. dimensions of the flanged end 6 iv will be such as to control the sp acing b'etween the points 60a.

A counterbalance weight 63 is secured in the upper rear corner portion of the arm 49 for counterbalancing the weight of the fountain pen or other tool arranged in the machine. This weight may be varied to compensate for tools of different sizes and weights. The purpose of this construction is to eliminate excessive friction of the pen point in its movement over the writing surface 37. Arranged at each side of the machine and upon the top plate 8 are two spring strips 64, the forward end portions of which are fashioned to form loops 65 for receiving the reduced ends of a transverse rod 66 and to form bearings therefor.

The spring strips 64 serve to support a backing roller 61 upon the feed roller 30 or the marking sheet or strip 31 disposed therebetween. The

strips 64 are secured in place by screws 68, and

these screws also pass through supplemental fiat metal strips 69 which extend rearwardly from their point of attachment as at 68 to act as spacers compensating for the thickness of the strip 37. Supported in the semi-circular bearings it at the rear ends of the spring strips 6 is a transverse guide rod H which simply serves to support the paper or other strip 3'? upon the top surface or wall 8 of the machine so as to provide'between the rod 66 and the rod H a substantially flat and smooth Writing surface. This is especially true when the size of the roll 31a diminishes.

In one side wall 6 of the machine, I provide an aperture with an insulated bushing 7:2 to permit the insertion of electric wires into the machine which are preferably coupled with a terminal block 73 and also with a control switch '14, the latter serving to control the supply of electric energy to the motor I2. The wire has been eliminated for simplification in the illustration.

In the operation of the machine and from the position of the pen indicated in Fig. 2 of the drawing, the pen will continue to travel upwardly until it reaches the upper point We terminating the partial ellipse marked on the sheet 31, at which moment, the flange 6| passes beneath the roller t2 and the pen is raised. As the arm continues to swing, the ratchet 51 strikes the finger 58 to slightly rotate the pen in its support, after which the arm will again be lowered to start the next elliptical marking at the end We located at the lower part of Fig. 2. 1

From this point, the pen will travel in the elliptical path back to the position shown in Fig. 2,

thus completing one cycle of operation. In this cycle of operation, the sheet 31 is advanced for wardly a slight extent to provide the spacing be tween the successive elliptical markings, and this operation is preferably performed while the pen is raised from the-sheet 31. From this standpoint, it should be borne in mind that the particular location of the arm 59 shown in Fig. l of the drawing is purely for simplifying the illustration. However, the movement of the sheet may take place at any time and may be moved claim as new and desire to secure by Letters Patent, is:
