To all whom it may concern:

Be it known that I, FRIEDRICH WmKnN's,

av subject of the German Emperor, andre Carrying Linoleum into Inlaid-Linoleum justed' by means of change speed gear tov Presses, of which the following is 'a's'peci fication.

This invention relates to mechanically driven devices for feeding the supporting fabric together .with the loose. linoleum mass applied thereon in the forin of a pattern to inlaid linoleum presses. v

It was heretofore customary for thesupporting fabric together with the loose linoleum mass applied thereon to be fed forward to the inlaid linoleum press either by hand or byrmeans of a motor e. mechanically. In both cases the supporting-fabric could not readily be fed an exactly predetermined distance, nor was it possible to main the hourly capacity at a maximum, because in the one andin the other case the feed was subject to the estimate of the operator both as to the speed and the intervals at which it was to take place. I

A primary object of this invention is to obviate these disadvantages and to secure not only a uniform feed of the supporting fabric, but alsoto render the feed independent of the judgment of the operator.

To this end, according to one form of my invention 1 provide a remote control time switch which closes the circuit ot'the magnet ofan automatic starter and thereby connects into circuit the driving motor for the feed of the web 'of fabric. A quickb'reak switch is-thereby driven by the feed roll of the fabric; this'switch can be ad;

various lengths of feed and releases the electromagnetof the automatic starter by means of the remote control time switch whose clockwork it simultaneously winds up. An electromagnetic brake connected in shunt provides or the motor stopping as rapidl as. possible. At various parts" of, the table for the inlaid work are provided press" switches which enabled-he operator to prevent the motor starting early. At the time switch is provided in addition a show.

cit-uniting switch for allowin" the motor to run cont nuously when a war edmp belt of jute is to be replaced and a new supportin fabr'ieis to be drawn in.

According to another form of the inventionthe driving motor is cut into and out of circuit entire electrically in such a manner that the feed length of the linoleum can be readily varied during the feedin operation and that the interval between t e stopping and restarting of the driving motor can be readily varied as desired durin the manufacture of the next length of amino. leum to be drawn forward. 4

Another improvement of this modification is the provision of two contacts interpolated in the circuit of the driving motor. One of the two contacts is connected with the press stamp and the other with the pat- LIND- if the press stamp and the pattern lifting frame rest upon the linoleum. Therefore,

.the motor circuit can only be closed when both the stamp and also the frame are lifted from the linoleum.

In the accom anying drawin Figures 1 (to 4 and Figs. 5 to 9 show two lllustrat-ive embodiments of the invention by Way of example. Fig. l is' a top plan view showing the "en'eral arrangement of the plant accordmg to the one embodiment, Figs. 2 and 2 are front andend elevation, respectively,

showin the quick-break switch connected with a change speed gear, Fig. 2 shows a detail of Fig. 2. Fig. 3 is a diagram of conmotions and Fig: 4 shows the remote'control time switch in elevation. Fig. 5 is a top.

plan view showing the general arrangement of the entire plant according to the second embodiment, Fig. 6 is a diagram of connections, and Fig. 7 vshows the time switch for to ping the driving motor in elevation; Fig 8 shows, enlarged, the switch mechanism comprised in the diagram Fig. 6, and

Fig. 9 is aside elevation of the driver for the contact which limits the feed of the web of fabric.

Referring firstly to Figs, 1 to 4,, the drive of the feed roll for the conveyor belt a" carrying the web of fabric isbrought about by 'a remote control time switch a of any desired "construction (Figs. 1 and 3) whi h closes the circuit of the electromagnet of an automatic starter 6 over an electric resisttime b" 120th of knownconstruction by which the driving motor an started. ,4

45 I which is clamped a leather .ring displaceremote control time ofclockwork mechanism by means of a lever a whose one arm carries a pawl a coacting with the teeth of a ratchet a fast OIlrthG shaft of the first driving wheel a. The other arm of the lever a is formed as a toothed sector in which meshes a second toothed sector constituting the end of one arm of a bell-crank lever a". The other arm of this bell-crank lever carries the armature a of the electromagnet a which is- :connectecl wit-h the hereinafter described quick-break switch and attracts its armature -when the quick-break switch is closed. The glever a? is thereby rocked upward by means of. the two toothed sectors and the a 'is' tensioned. The latter then acts by means of the pawl a on the clockwork mechanism whose pendulunrbob a is adjust-able,-in order that the time which the clockwork requires until it has run down oruntil the'spring a is distensioned may be adjusted as desired. This time switch a comprises two contact pieces I), b which are apart while the clockwork is working and are'connected to the coil of the magnet of the automatic starter b. When the clockwork has almost run down the lever a is in the position shown in full lines in Fig. 4 and under the influence of the spring a presses together the two contact pieces 6'. W. The circuit of the .coil of the magnet of the automatic starter Z) is thereby closed and the driving motor 0 started. This motor 0 drivesthe feed roll i-through the medium of a. clutch d, worm gearing e, the countershaft f and spur gearing g, h. The shaft of the feed roll 2' carries a sprocket wheel Icprises any desired suitable change speed gear consisting, for example. of two adjacent conical rollers n, n, (Fig. 2) between abie longitudinall of the rollers by means shaft n of a manually driven screw 0'. so that the rotation of the one conical roller 71. is im-' parted by the leatherring a to the other roller n Keyed on the. one end of the of'the roller 91. is an arm 72, having a slanting face p, (Fig. 2 and loose on the same end of the -shaft is a collar ;0 composedof insulation havinglet into one part of its periphery a contact piece 72 (Fig. 2). Against the periphery of thecollar pslide two insulated contact springs p, p which are connected with the coil of the electromagnet a of the remote control time. switch a. (Fig. 4). The collar 39 is connected with the one end of a springp whose other end is secured to the shaft 71". Below this shaft is mounted a spring-pressed bolt 72' which generally projects so spring contact pieces 5', 6

far toward the collar 7; that the stop 32? carried by the latter bears against it, so that the collar is locked and cannot rotate with the roller 12. (see Fig. 2 dotted lines). In this position the two contact springs bear on the insulation of the collar p, as shown in Fig. 2 in full lines so that no current can flow through them. The bolt p has a notch which coacts with the slanting face p* of the arm 7;". Now when the roller n rotates, the spring 17' connected with the collar p is tensioned because the collar cannot rotate owing to its being held by the bolt p. After about one rotation of the roller '21, the face 3; of the arm 7) pushes the bolt 7) backward, so that the collar 7) is released and under the action of the spring 79 rotates approximately one revolution, its contact piece 19 electrically connects together the two contact spring 7), p for a short time, so that the electromagnet a of the remote control time switch connected therewith is energized, the clockwork is wound up and the spring a is tensioned. Simultaneously, the (Fig. 2) are separated. The circuit of the automatic starter b is thereby broken, so that the circuit of the motor a and, simultaneously, that of a braking magnet q. of known construction which influences the hand brake 1' (Fig. 3) is broken. The hand brake is applied and the motor 0 at once stops. The outer casing of the clutch between the motor 0 and the worm gearing e (Fig. 1) may serve as the brake disk. Immediately after the collar 7) is released the bolt p" is likewise released by the arm-p and snaps back so that it again locks the collar 7).

After the elapse of a predetermined time controlled by the time switch the latter, whose clockwork was wound up when the drive of the feed roll 5 was stopped by the quick-break switch 1), switches the automatic starter 6 into circuit again, whereby the braking magnet (7 is again energized and the band brake 7' released. The motor 0 also starts simultaneously. 'The play is'then repeated afresh. As long as the motor runs the conveyor belt 6' is driven and the jute fabric on the belt and the loose linoleum mass applied on the jute fabric are fed under the press.

It is obvious that the speed of the feed and of the change of the interrupted drive of the conveyor belt z" can be adjusted at the time switch a and at the speed change 9%, n as desired within certain limits.

' Referring now to Figs. 5 to 9, the gen eral arrangement of the driving mechanism fort-he feed of the web of fabric of the second illustrative embodiment is substantially the same as that described above. A conveyer belt 5 for carrying the web of fabric having the linoleum mass to be applied thereon runs over rollers z, of which that gearh meshing with a pinion 9 whose shaft f is driven through the medium of worm fgearinge by the driving motor a when the brake 1' is released bya magnet q. Connected in series with the motor a is an automatic starter I) connected with the switch:

gear a in the manner which will now be described. This switch gear a maybe ar ranged in various ways, 6. g. as in Fig. 8. A switch lever 2, carrying an armature 2', and able to rock about a pivot 1, is under the influence of two electromagnets 3, 4 and carries at its free end apiece of insulation 2 The latter carries two pairs' of wiping springs 5 and 5, the two springs of each pair being connected together. Two stops 6 and 7 limit'the range of motion of the lever 2; On' the one side in the direction of osc-illation of the springs 5, 5 are contact pieces 8, 9 'and 10, 11 and on the other- side contact pieces 12, 13 and 14, 15. Of these, the contact piece 8 is connected with the electromagnet 4 (Fig. 6) and the cont-act piece 12' with the electromagnet- 3. The two electromagnets 3, 4 have a common return conductor 16. The vconltactpieces 11'and 15 are connected to the feeders. The contact piece 10 leads to the automatic starter b of the motor 0. In the circuit of the contact piece 10 to the automatic starter b are interpolated two contact pieces 17, 18, each of which possesses a weighted lever .17 and 18', respectively, tending to keep the contact open. These weighted levers are located in the range of motion of stops at, y of the press stamp 00, and of the frame y, respectively, each of which in its raised position closes its contact. The contact 9 leads to a feedlimiting contact 19 provided on the press. 00 (Figs. 5 and 6). The contact 14 leads to an auxiliary motor 2 of a remote control time switch which is shown by itself in Fig. 7 and possesses three switch drums 20, 21, 22 fast on the same shaft 31. Each of'these three drums is wiped bV two contact springs 23 and 24, 25 and 26, 27 and 28, respectively. Of these, the springs 24, 26 and 28 are connected to a common return conductor, while the spring 23 leads to the contact piece 13 of the switch gear (1 (Figs. 6 and 8') and.

the spring 25 to the auxiliary motor 3. In

addition, a return conductor 11-, in which is interpolated a lamp-resistance 10. branches off from the line between the motor .2 thespring 25. A call bell t-is in'ter -)olated inthe line connecting the spring 27 with the feeder.

I ing 3Q" to the shaft 31. The two switch The time switch'driven by the auxiliary motor 2 (Fig. 7 )"isarranged as follows:''

The auxiliary motors directly or indirectly drives the pulley 29 whose motion is speeded -down and tr-ansmitted by means of double worm-wheel earing contained in] the caspcaasc drums 21and 22 are fast on this shaft;

Each of the drums possesses only at oneipart.

cf'i'ts periphery a contact piece. for connectmgthe spr ngs 25-, 26.and{27, 28, res ectively. Fast on the-shaft ,1 is not on ya disk 32, carrying'a stop 33, ut also anfarm p havlng a slant ng face 7), while thedrum 201s looseon the shaft 31.- The rim of the drum 20 is connected with" the one-end-of a.

spring p whose other end is secured to the shaft 31. A spring-pressed bolt p is guidedunder the latter in the frame 34 and the bolt I p generally projects so farthat the detent p of the drum 20 bears against it, as shown in dotted lines in Fig. 7, so that the drum 20 cannotparticipate in the rotation of the shaft 31. In this position the two springs 23, 24 bear on the insulated part of the drum 20, so that no current can flow to the electromagnet 3 of the switch gear a (Figs. 6 and 8). The bolt p has a recess which coacts with the slanting face 1* of the arm 72 The arrangement and motion of the drum 20 correspond to those of the quickbreak "switch ofthe form described-above with reference to Fig. 2. When the shaft 31 rotates the spring]; mounted thereon and connected with the drum 20 is first tensioned, because the drum 20 cannot rotate as it is held by-the bolt 17'. After the shaft 31 has rotated almost... one revolution the face 12 of the arm p pushes the 'boltp back so that the latter releases the detent p and the drum 20. This drum is then driven around almost one revolution under a pin 38 which is within the reach of the stop 33 of the disk 32. As the drum 2Q rotates only when the shaft 31 has already rotated almost one revolution, the stop 33 leads as much in front. of the pin 38, and thus admits if almost a complete revolution of the drum 20. The face p of the arm 72 has such a position that is-releases the bolt 7) immediately after the release of the drum 2O inorder that it can 'fly back and again lockthe drum '20. Y' The described apparatus operates as follows z-As'sumingthat the switch lever '2 its pairs of springs 5 and 5 hridge the con-. tact. pieces 8,9 and "10,11.

"The bridging of the contact pieces 10, 11 by the pair of springs 5' bringsxabout the connection in-circuit of the automatic starter 1), whereby the motor 0 is started while the magnet 9 simultaneously releases thebrake r. The motor a can, however, start only when the weighted lever 17 arranged in front of the hydraulic press a: is lifted and closes the contact 17 and,also, only when the frame y by lifting the weighted lever 18 has closed the contact 18. The latter contact is a special means of security to prevent the motor 0 from being started, if the frame 1 together with templets resting on it after having been filled with linoleum I is not lifted from the part of the length of linoleumv having been just prepared to be drawn under the press. Owing to the motor 0 being driven the feed rolls i are driven through the medium of the transmission e, f, g, h. and the length of linoleum is fed under the press :22. The drivers is placed back on the linoleunr a distance equal to that which the linoleum is to. be fed for-. ward. When the required length of linoleum has been pulled under the press the driver 8 abuts against the contact piece 19 and closes its circuit, so that the electromag-' net 4 is'energized and pulls the switch lever Con- 2 over into its right-hand position. sequently, the connection between the contact pieces 8, 9 and 10, ll is broken and instead thereof the contact pieces 12, 13 and 14, 15 are respectively connected together. The electromagnet 4 is deenergized, the brake r is applied as the magnet 9 becomes the motor 0. Owing to the contact pieces .14 and 15 being connected the\auxiliary motor a is. connected in circuit and drives the shaft 31. When this motor first starts the springs 25, 26 are. still resting on the contact piece of the drum 21, and consequently this motor 2 obtains current directly for the purpose of overcoming its starting moment. Owing to the shaft 31 being driven the drum 21 is also rotated until its contact piece slides away from the springs 25, 26 and stops the direct supply of current for the auxiliary motor a. For this motor there then remains'open only the circuit over the lamp-resistance to, so that the speed of this tkmotor is slowed corresponding to the numer of lamps in the circuit .for the. time be 1 g. Obviously, by varying the resistance r and with it the speed of the auxiliary motor ans well as, of the drums 20, 21 22, the time betweenthe stoppage and restarting of the motor 0 can be varied as desired. Instead of a lamp-resistance any other kind of resistance may, of course, be employed.

When the driver a has fulfilled its object namely actuating the contact 19, it is place by hand back a distance equal to the next lengthof the feed, in order that when the linoleum is next drawn forward it can op.- erate afresh.
