The word paspartout comes from the French and in the commercial field means to affix tape upon the lamp shade or the like for ornamental as Well as for reinforcing purposes.
Heretofore in the manufacture of lamp shades, paper baskets, picture frames and the 1il:e,.the tape, which is generally of ornamental design, has been alhxed upon the shade by hand. The tape has glue or some adhesive material on one side, and this side is brought into contact'with the article to be paspartouted. First the tape is cut the proper length, then the adhesive side of the tape is daubed with water by a brush or sponge, and finally the tape is properly placed on the desired edge of the shade so that 'a small portion of the tape width willencircle the wire frame and adhere to the under side of the shade, and the larger pertion of the tape Width will adhere to the outer side of the shade along the 9 desired edges The top edge of the tape may be out in an ornamental design, such as the familiar scalloped edge formation. generally cut on the bias, but it may also be cut transversely with the tape and it may be obt ained in various colors to suit the design of the shade. Girls Working at a low rate of compensation are generally employed to paspartout or to afiix the tape upon the shade. The following disadvantages of the above method will readily be noted:-The method is slow and ineflicient and considerable difficulty is encountered to accurately and uniformly aifix the tape to the shade over its entire circumference, the opera.- tors handling of the daubed tape results in soiled hands which are very apt to also soil ordirty the shade, and daubing the tape with a brush, sponge or the like has the efiect of wiping 01? part of the glue and not properly moistening the remainder of the glue so that a low degree of adhesiveness is obtained between the tape and the shade. Due to the above defects, it is conservatively estimated that 20% of the lamp shades manufactured are defective either at the place of manufacture or by the trade in the form of returned goods.
Our invention will be described for use on lamp shades only, but it will be understood that it is equally applicable to waste-paper baskets, pictures and all other devices requiring the af-' fixation of tape or the like.
The principal object of the invention is to provide simple, efiicient, durable and fast operat ing apparatus for paspartouting the tape upon the shade Without soiling-the shade or even the operators hands.
The tape is,
he tape While it is under tension when being affixed upon the shade. It will-be noted that none of the glue iswiped off and that all the glue, including the tape becomes very flexible because of the action of the hot steam'vapor under pressure upon the tape. 1
A further object of the invention is to provide a novel method for paspartouting the tape tautly around the frame of the shade and also over any irregularities in the diameter of the frame due to staples and the like. This is accomplished by the use of a split drumunder proper spring tension.- 1 o A further object of the invention is to provide a tape cutting mechanism which cuts the tape at any predetermined length as desired for the particular circumference of shade being paspartouted;
A further object of the invention is to provide a novel and highly eiiicient method for carrying out the paspartouting oithe tape upon the edges of the shade by operating at a high speed, and in an economical and efificient manner so as to minimize the number of defective shades,
A further object of the invention to provide a machine-for the above described purposes and one which Willrender very few defective shades, if any, so that after the general inspection, no shades will be returned by the trade because of unsatisfactory paspartouting of the tape upon the shade.
These and other objects and advantages of the invention will be fully set forthin the following description made in connection with the accompanying drawings, in which like reference characters refer to similar parts throughout the several views, and in which:.-

In the drawings 5 represents the base with a hollow interior section and upon which is mounted a source of mechanical p ably a fractional horse-power motor M suitable for the freq ency and of the urce of electric power supply. A universal single-phase series motor for energization by 115 volts and from one-tenth to one-fiftieth horseow ing and having a suitable speed reduc satisfactory. Other sources of mechanirm pow may equally well be used todrive the machine, including a crank for manual opera ion.
The motor M through its speed reducing sys tem which is integral with the motor-M has a slow speed shaft 15 upon which is aflixcd the driving gear 16. the idling gear 17 which in turn dives both the lower drum gears 18 and 19. With the operating lever .L in engaging position as clearly shown in Figs. 1, 2 and 4, the upper drum gear 29' is in the lowered position under spring tension so that the upper drum gear meshes with the lower drum gear 19. Thus with the slow speed shaft 15 of the motor M rotating in clockwise direction when looking at the slow speed shaft 15, it will be :apparent'that both lower drum gears 18 and 19 will rota'te'in the same direction while the upper drum gear 20 will rotate in counter-clockwise direction. For convenience,
jar cut 23 is .aiiixed to the idling gear 17.
The'driving gear 16 engages all gears have the same diameter and number of teeth in the drawings, but variations may be made in the two gears 16 and 17 to obtain other operating speeds.
An upright supporting member 21,-preferably a casting, is rigidly affixed to the base B at its lower end by means of several screws 22. The upper end has tiree bearings pr pcrly located and machined for shafts 23, 24 and 25. Shaft The head ends of shafts Z land 25 are constructed in the form of a drum or roll 26 and 27 respectively to form a pulley for the belt 28 to travel over. The shafts 24 and 25' are each provided with a shoulder or collar 29 to hold the drums 26 and 2'7 in proper operating position, as clearly shown in Fig. 10. The shafts 24 and 25 are supported by their bearings in the upright supporting member 21 and extend therethrough so that the two lower drum gears 18 and 19 may be rigidly afiixed by means of small keys to the extensions of shafts 24 and 25 respectively.
The upper drum gear 20 is ri idly affixed to the front end of shaft 30 which is supported by its bearing 31. The arm 32, which carries the bear'ng 31 is pivotally mounted on the pin 33 which is supported by the top of the upright supporting member .21, as best shown in Figs. 1 and 4. The bearing 31 is affixed to the rods Bland .35, the latter being under spring tension by means of. spring 36, as shown in Fig. 12. The split drum maybe raised to insert or remove the shade S from themachine and it is lowered to bring pressure upon theshade S and tape T to form the tape and drive h shade S and tape '1" through the machine.
teferring to 18, the rear portionof the shaft 30 is constructed in the form of asplit drum or roll so as to'take care of irregularities in the diameter of the frame F of the shade S due to staples or other thickness variations in or about the frame F. The female member 37 of this split drum be constructed integrally with the shaft 30. The male member 38 is yieldingly held in position by means of a spring 39 and screw 40. The annular U-shaped groove i1 is formed by the cooperation of members 3'7 and38 so that approximately half of the groove is in the female member 37 and the other half in the male member 33. The diameter of the groove 41 is approximately equal to that'of the frame F plus the thickness of two layers of the cloth of tape T without any glue thereon. Thereby the U-shaped groove 41 fits snugly about the tape T andframe F, and if some vari.a tion in diameter encountered, due to staples being fastened around the frame F and shade S at various points or due to any other causes, the spring 39 will yield suific" ly to over such variation without losing its snugness about the tape T and shade S. A small 1111142 is rigidly affixed to the inner face of the female member 87 and it protrudes into an oversize cylindrical hole 43 in the outer face of the male member 38. Thus when the shaft 80 rotates, the pin on gagement provides positive action male member 38 must also rotate in unison with the female member 3'? shaft 3:2. The outer annular face of the male member 38 is provided with a cylindrical resilient tire 44 made pref-- erably of suitable rubber material. This tirev 4a in combination with the belt 28 furnishes sufficient tractive power to force the shade S be so that the Bracket is anixed to the under face of the base B by means of a screw 16 and carries a pin 47 on which the lever 43 is pivotally mounted as clearly shown in Figs. 11, 12 and 13. The front end of lever 48 is held in operating position by means of another bracket 49 which is also affixed to the under of base B. Spring 50 is seated in the brack t and directly beneath the lever 48 so that tl normal position of the lever 48 will be in the raised position in which case the upper drum gear 26 is, not
in engagement with the lower drum gear 19 and the electrical contact 51 is open. By operating the lever L from its vertical 1. tion to the horizontal position, the eccen ip of rod 52 is swung into the downward n shown in Figs. 11, 12 and 13. T s cle resses the lever 48 to lower the rod 35 which L 'ies with it the upper drum gear 29 into engaging position with the lowerdrum gear 19. In case the teeth of the upper drum gear 2-9 and lower drum gear 19 should not mesh at tl e first point of contact, the spring 36 will allow the lever arm 19 to close the electrical contact 51 which starts the motor M. When the motor has rotated suficiently, the lower drum so that the teeth of its gear 19 will mesh with those of the upper drum gear 29 which is under the tension of spring 36.
The shade S is held in proper position by means of an adjustable holderf The slotted arm 53 is affixed to the B by screws 54 as clearly shown in 4. The extensible bar 55 with a slit in i is held in sition within the slot of 53 the thumb screw 58, the ead by means of whiclis r;
idly affixed to arm 53 to event turning. A vertical bar 57 with a slit in it is axed to the rear extremity of the or ensible bar 55 by means of screws 59. A cylindrical roller 59 is rotatably mounted on screw 66 which is atfixed to the top or" the vertical bar 57 and at a proper height to correspond with the top-surface of the belt on the drums 26 and 27. An arm system comprising arms 61 and 62 rotat ably mounted on screw 50, and arms es and 64 rotatably mounted on the thumb screw 65 is provided. The other ends of 61 and arm 63 are hinged on screw on which is rotatably mounted a tapered roller 67, this roll being tapered to accommodate the taper of the shade S. The other ends of 62 and arm 64 are similarly hinged and carry the tapered roll 68. It will be readily noted that the above described holder will accommodate various heights, diameters and tapers of shades by only.
a casting, is rigidly aiiixed at its lower end to the base B in any convenient manner, such as by. several screws 70. The upper end of supporting member '69 carries a vertical shaft 71, the extremity of which is threaded to take the thumb nut 72. The tape supporting disk 73 rotates freely about the vertical shaft 71 by means of a ball bearing 74. The cover for the tape T is held in the proper position by the thumb nut 72 so that the exit 76 for the tape T is in approximate alignment with the guide G. Fig. 1 shows a section of the cover 75 cut away so that a portion or the roll of tape T is shown and the manner in which it passes through the exit 76 into the guide G.
The guide G for turning and guiding the tape 19 will turn to the tape applying mechanism comprises two metal plates 77 and 78 with two strip spacers 79 and 89 between the. plates at the top and lower edges so that the'tape T may easily pass through. The plate 78 does not extend to the tip of the guide G in order to leave space for the spray of steam which lully described. Plate 77 forms the tip as best shown in the enlarged cross-sectional view of Fig. 9. The tape may be raised or lowered within the guide G by means of screw 81 which raises or lowers the short strip 82 at the front end of the guide G.
In order to. obtain proper tension and the corroot length for cutting the tape T, a cylindrical drum 83 with a resilient tire 84 is provided to bear upon the tape T through the rectangular slot 85 in the plate 77. On the opposite side of the guide G, an adjustable fiat spring 86 with rotatable roller 87 is provided to bear upon the tape T through a small rectangular slot in the plate 78. guide G is downwardly inclined at a small angle so that the resilient tire c4 of cylindrical drum 83 will bear upon the tape T to keep the tape up against the top spacer 79 or" uide G as clearly shown in Fig. 7.; The guide (3- is supported at its tail end by a v shaped bracket 88 which is rotatably mounted on the vertical shaft 89, and its tip end is supported on a small bar rest 90. The tip is yieldingly held in its proper position by a protruding pin 91'under tension of spring 92 as best shown in Figs. 1 and 9. The tip of the guide G is prevented from sliding too far back by the vertical projection 93. The above construction provides for uniformity in paspartouting the tape, T upon the shade S irrespective of variations in the diameter of frame F or to staples around the frame F and shade S. It will be seen that the operation of the cut ting mechanism is dependent upon the trio tional engagement of the cylindrical drum 83 to the tape and that the movement of the tape through the guide G is controlled by the gear movement of the drums which are driven by the motor.
A center upright supporting member 94 has its lower end rigidly aiiixed to the base 13 by several screws 95. The portion forms a bearing for the vertical shaft 89 which carries the cylindrical drum 83 and the knurled knob 96 which may be used to rotate the drum 83 by hand. The lower end of the vertical shaft carries a small spiral gear 97 which is in engagement with a larger spiral gear 98. Any gear ratio may be used, but a one to four ratio provides a convenient one in that the tape T for any shade S up to 24 inches in diameter may be measured and also cut by means of a, six inch disk 99. The larger gear 98 is 'afiixed to the shaft 100 which has two bearings, one in the right side of center upright supporting member 94 and the other bearing 161 being in the arm 102 whichis affixed to the center upright supporting member 94 by several screws 103. A
disk 104 with a resilient tire 105 is mounted on the shaft 1G0 and its position can be longitudinally varied by turning the handle 196 of wheel 107. A longitudinal keyway 1G8 in'the shaft 160 engages with a traveling key 109 affixed to disk 104, so that the disk 19d must rotate in unison with shaft 109 at all times. The wheel 107 is affixed to the long threaded screw 110 whichhas bearings in the endand base portions of the arm 102. The fork 111 is internally threaded to fit will hereafter be the long screw and its upper U-shaped portion engages an annular groove 112 which is integral with the disk 104. The six inch disk 99 is held in a vertical plane andunder spring ten sion 'by means of spring 113 so that the face of the disk is always'in contact with the resilient tire105 of disk 1G4.
The face of the arm 102 has a calibrated scale on it which corresponds to the diameter of the shade S. A pin 114-is aifixed to the face of the disk 99 and for each revolution, the pin 114 operates to 'close the electrical contact of 115 and 116 which energizes theelectromagnet to cut the tape T at the proper length to correspond with the setting of the fork 111 on the calibrated scale of arm 102. 0
The electromagnet consists of a suitable coil 117 wound on a laminated core 118 and armature 119, and is ailixed to the base B by several screws. The armature 119* is connected to a lever 120 which has a slit near its forward end which allows for a hammer-blow on the pin 121 when the coil 11'? is energized. Pin 121 is firmly secured to the bottom of the cutter C, and the stationary member 122 of the cuttermechanism is securely affixed to the plate 78 of guide G by means of screws 12:3. The cutter C is mounted within the guide G so that the tape l is always under control and a spring is attached to the lower end of cutter C to pull the cutter C back so as to always leave the guide G open except while the tape T is being cut. Thecutter C cuts the tape T at an angle so that the tip of the roll of tape T will be in position to adhere to the shade S and thereby the tape will be in alignment for starting the next paspartouting operation. Thus, if a shade of sixteen inches in diameter is being paspartouted, the handle 106 is rotated so that the arrow of fork 111 coincides with division 16 on the scale. As the tape T is being paspartouted upon the shade S, it drives the six inch disk 99 through its series of shafts,
gears and disk as explained above to the position where the pin 114 carries the contact arm 115 down until it snaps back to close the electrical contacts 115 and 116 which energizes the e1ectromagnet coil 117. This closes the armature 119 which strikes the cutter C with a hammer blow during the latter half of the armature travel. The cutter C operates in conjunction with the stationary member 122 to out the tape Tat an angl -the length of the tape T out being just the proper length for the circumference of the respective shade S.
Steamvapor is used to moisten the glue on the tape T as it is being paspartouted upon the. shade S. Any source of steam vapor may be used in conjunction with our machine and We have shownoone convenient source in the form of a small steam boiler A insulated from but aifixed to the base B by screws 124. The steam boiler A consists of a cylindrical boiler 125 with an electric immersion heating element 126 .mounted'therein near the bottom and a steam dome 127 mounted on top of the boiler 125., From this steam dome 127, the "steam is passed through conduit 128and directed upon the glue of the tape T. The end of conduit 128 may be flattened or shaped to better direct the spray of steam vapor. The boiler 125 is kept about two-thirds full ofwater by means of the jar'J which contains an ample supply of water. The jar J is held in position by its basket-shaped holder 129 and has sufficient capacity for at least a days operation. The proper level-of position.
water in the steam boiler A is obtained by the use of a float valve. The water inletpipe 131 is afiixed to the end 120 of steam boiler A and the said pipe 131 projects inwardly into the boiler and terminates by the valve seat 132 as best shown in Fig. 14. The valve blade 134 is closed or opened by the raising or lowering, respectively, of the float 135, and the valve blade 134 is held in proper operating position at all times by the valve guide 133 which consists of a narrow slot to accommodate the thickness of the valve blade 134. Other means of holding the water at the proper level may equally well be used, a sight drip' cock, pressure valve, pump and the like.
The operation of our machine may best be explained by going through the sequence of operations for paspartouting a shade. Thedesired tape T is placed in the tape holding machanism and the end of the tape .T is passed through the guide G. The jar J is filled with water and placed in its holder which then forces the proper amount of water into the steam boiler A. The operating 1e er L is in the vertical position so that the split drum is in the The electrical connection plug 12-6 is then connected to source of electrical supply which energizes the electric immersion in the steam boiler A to steam in'a few heating element produce a uniform flow of As soon the steam flows from the conduit 123, the machine is ready for continuous duty. The operator places the shade S in the shade holding mechanism with the edge to I be paspartouted n tween the split drum and the belt 28 on the two drums 26 and 27. The operating L is now brought into engaging position by turning it approximately ninety degrees to the right. This brings the upper drum gear 20 into engagement with the lower drum gear 19 so that the annular groove 41 of the split drum bears upon the frame F of the shade S and then starts the motor M which drives the belt 28 and split drum in directions so that the shade S will rotate to the left when viewed from the front. The tape T is now being paspartouted or over the wire frame F and upon the shade S by the rotation of the tape T and shade S between the pressure of the split drum and the belt 28. When the proper length of tape T has been obtained, the electric contact at 115 and 116 closed which energizes the electromagnetic cutting mechanism and thereby cuts the tape .5. at the proper length; The shade S now has the tape T affixed to its en tire circumference and the operating lever L is brought to the non-engaging position so that the motor lvF. stops and the shade S is removed therefi The next shade S is then similarly placed in the holding mechanism and since the tape T already within theguide G, it is only necessary to turn the knurled knob 96 until the tape 1 reaches the belt 28 after which the tape adheres to the shade S and the paspartouting operation thereafter follows the steps as described above.
It will be understood that our machine is not limited to the use or a single drum or a split drum as the upper member, because it is obvious that several drums or solid drums may also be used. It will also be understood that two or more drums may be utilized for the other member and that our invention is not limited by the number of drums used.
It will, of course, be understood that various changes may be made in the form, details, proportions and arrangement of the parts, without departing from the scope of our invention, which, generally stated, consists in a device capable of carrying out the objects above set forth and in the novel parts and o disclose-:1 and defin What claimed 1.
