Gasslarapparat. Gas detector.

Foreliggande uppfinning avser en gasskarapparat, vars brannare är anordnad p& ett med lonhjul forsett stativ och vilken är forsedd med en fran stativets lophjul medelst kuggvaxel driven regleringsanordning for apparatens framforingshastighet, bestaende av en med ,en utefter en i stativet lagrad, av kuggvaxeln driven axel rorlig styrhylsa forsedd skiva, anordnad att paverkas av tvenne i sina ena andar vid axeln, i sina andra andar vid styrhylsan ft skivan fasta flata fjadrar, forsedda med pa dein anordnade vikter och anordnade att vid Okande framfOringshastighet boja sig utat fran axeln och att darvid draga styrhylsan med den roterande skivan narmare en svangbar och installhar regleringsarm, vid vars beroring med den roterande ski-van den uppstaende friktionen medf Or en bromsning av framfOringshastigheten och kannetecknas darav, att regleringsarmen ãr utformad som tvaarmad havstang och installbar medelst en fjader, som motverkar verkan. av regleringsarmens egen vikt, en stallskruv, som bestammer andiaget for skivans namnda rOrelse i rihtning mot regleringsarmen och for vikterna, och ett fjaderstift, vilket vid nedtryckning astadkommer ett hastigt stoppande av apparaten. The present invention relates to a gas cutting apparatus, the burner of which is arranged on a stand provided with a pulley and which is provided with a gear-driven control device for the feed speed of the apparatus, consisting of a shaft driven along the shaft by a shaft driven by the gear shaft. guide sleeve provided with a disc, arranged to be influenced by two in one of its ends at the shaft, in its other ends at the guide sleeve with the disc fixed flat springs, provided with weights arranged thereon and arranged to bend outwards from the shaft at increasing speed and thereby pull the guide sleeve with the rotating disc closer to a pivotable and installing control arm, in which contact with the rotating disc the resulting friction causes a deceleration of the feed speed and can be characterized by the fact that the adjusting arm is designed as a heated sea rod and can be installed by means of a spring which counteracts action. of the control arm's own weight, a stable screw, which determines the capacity of the said movement in the direction of the control arm and of the weights, and a spring pin, which when depressed causes a rapid stopping of the apparatus.

En lamplig utforingsform av uppfinningen askadliggores a ritningen, ft vilken fig. 1 schematiskt visar apparaten eller maskinen sedd frail sidan, fig. 2 densanama i sektion, sedd frail anden, och fig. 3 regleringsanordningen i storre skala. An exemplary embodiment of the invention is illustrated in the drawing, in which Fig. 1 schematically shows the apparatus or machine seen from the side, Fig. 2 the ones seen in section, seen from the other side, and Fig. 3 the control device on a larger scale.

Pa en vanlig skarbrannare 1 aro anbragta ett eller tva raffia& slaphjul 2, vilka vid slap- ningen av skarbrannaren under skarningen av ett foremal 16 medelst axeln 3 och kuggvaxeln 4, 5, 6, 7, 8, 9 satta en regleringsanordning 17 for maskinens framforingshastighet i hastig rotation. Regleringsanordningen bestar av en. i stativet lagrad, av kuggvaxeln driven axel 18, kuggdrevet 9, en skiva 10 med styrhylsa, rorlig utefter axeln, vikter 11, lampligen metallskivor, samt vid styrhylsan ft skivan 10 fasta flata fjadrar 19. Dartill kommer den svangbara regleringsarmen. 13, som ãr installbar medelst skruv 14 och fjaderstift 15 och vid vars beroring med den roterande skivan den uppstaende friktionen medf Or en bromsning av framforingshastigheten, ()eh nedtryckning av sparrstiftet 15 ett hastigt stoppande av maskinen. Spiralfjadern 12 avser att motverka verkan av regleringsarmens .erren vikt. One or two raffia & slap wheels 2 are arranged on an ordinary cutter burner 1, which, when the cutter burner is slapped during the cutting of a mold 16 by means of the shaft 3 and the gear shaft 4, 5, 6, 7, 8, 9, is set to control the machine 17 in rapid rotation. The control device consists of a. in the frame mounted, shaft 18 driven by the gear shaft, gear 9, a disc 10 with guide sleeve, movable along the shaft, weights 11, suitably metal discs, and fixed flat springs 19 attached to the guide sleeve ft disc 10. In addition, the pivotable adjusting arm. 13, which can be installed by means of screw 14 and spring pin 15 and at the contact of which with the rotating disc the rising friction entails a slowing down of the feed speed, () a depression of the ratchet pin 15 a rapid stopping of the machine. The coil spring 12 is intended to counteract the action of the weight of the control arm.

Vid hastig rotation av regleringsanordningen 17 tvingas vikterna 11, 11 langre fran axeln 18, och skivan 10 med sin pa axeln rorliga styrhylsa drages narmare kuggdrevet 9 me-deist de flata fja.drarna 19. During rapid rotation of the control device 17, the weights 11, 11 are forced further away from the shaft 18, and the disc 10 with its guide sleeve movable on the shaft is pulled closer to the gear 9 by means of the flat springs 19.

Genom friktionen mellan skivan 10 och regleringsarmens 13 hogra ande sker darvid en bromsning av brannarens alit for hoga fram- foringshastighet, och med regleringsarmen 13 och skruven 14 Indies skivan 10 och darmed Liven vikterna 11, 11 i onskat, framforings- hastigheten bestammande lage. Fjaderstiftet 15 tryckes ned nar skarningen shall avslutas, varvid en kraftig bromsverkan astadkommes. Slaphjulens .antal kan vara ett eller tva, och stodrullar 16' tjana som sidostod vid anordningen. Due to the friction between the disc 10 and the riser of the control arm 13, the burner's alit for high feed speed is braked, and with the control arm 13 and the screw 14 indies the disc 10 and thus the weights 11, 11 in the desired, the feed speed determining position. The spring pin 15 is pressed down when the cutting is to be completed, whereby a strong braking effect is achieved. The number of slack wheels can be one or two, and support rollers 16 'serve as a side stand at the device.

Med anordningen erhalles pima ytor, framforingshastigheten ar jamn och gasatgangen With the device, five surfaces are obtained, the feed speed is even and the gas supply

Claims

Claim claim: Gas cutting apparatus, the burner of which is arranged on a stand provided with an impeller and which is provided with a control device (4, 5, 6, 7, 8, 9) driven from the frame impeller (2) by a gear shaft (2, 5, 6, 7, 8, 9). , consisting of one with one along one mounted in the frame, driven by the gear. shaft (18) movable guide sleeve provided with disc (10), arranged to be influenced by two in one of its ends at the shaft (18), in its other ends at the guide sleeve ft the disc (10) fixed flat springs (19), provided with on them arranged weights (11) and arranged to bend outwards from the shaft at an increasing feed speed and to thereby pull the guide sleeve with the rotating disc. (10) closer to a pivotable and installable control arm (13), at the touch of which the rotating disc (10) touches the rising friction causes a deceleration of the feed speed, which may be characterized by the fact that the control arm (13) is designed to as a double-armed sea rod and can be installed by means of a spring (12) which counteracts the action of the control arm's own weight, a stable screw (14), which determines the movement of the disc vans (10) in the direction of the control arm (13) and for the weights (11), and a spring pin (15), which, when depressed, provides a rapid stopping of the apparatus.
