To all whom it may concern:

Be it known that I, Ennsr SoHnLLHAss, a subject of the German Emperor, and residing at Berlin, Germany, have invented certain new and useful Improvements in Conveyor Apparatus for Feeding Bars of Metal to and Delivering the Same from Machines, of which the following is a speclfication. v

The present invention relates to improvements in conveyers especially adapted for feeding bars of metal, or girders to a drilhng or other metal working machine,.and particularly to means whereby the artlcles to be operated on by such machine are delivered or fed to such conveyer. In accordance with this invention a series of the articles to be transported by the conveyer are stacked upon a suitable stationary support arranged at one side of the conveyer and means are provided by which said articles are successively removed from the stack and de posited on the conveyer, such means belng controlled by a single hand lever.

In the accompanying drawings, Figure 1 is a front elevation of a conveyer such as hereinbefore referred to and means for delivering articles thereto embodying the present invention; Fig. 2 is a vertical transverse sectional view through the conveyer and such feeding means; Figs. 3, 1 and 5 illustrate in elevation, plan and detail section the clutch mechanism employed for connecting the feeding devices with a driver; Fig. 6 illustrates a slight modification.

Referring to the drawings, 1, 2, designate a pair of supporting beams on which are arranged a series of transverse beams 3 constituting a stationary support for the articles to be transported by the conveyer which in the embodiment of the invention illustrated are I-beams 1. As shown the members 3 of said support are arranged in an inclined position and provided at their lower ends with upwardly projecting stops 5 against which the lower one of the series of beams t bears.

The particular form of conveyer illustrated comprises a series of rolls 20 mounted on shafts 2O supported by suitable uprights or standards and the several shafts are connected by chain and sprocket gearing so that articles deposited thereon will be carried toward a suitable metal working machine, such as is conventionally illustrated at 21.

Between the aforesaid stationary support for the articles to be transported and said conveyer are pivotally mounted a series of arms 9 adapted to be held in the position shown in full linesin Fig. 2 to form an inclined way or slide extending from said support to the conveyer and to rock about their pivotal support so as to deposit on the conveyer articles previously supported by them. As shown, said arms 9 are mounted to rock about a shaft 8, which is supported in suitable bearings 7 provided at the upper ends of frame 6 and the lower end of each arm is adapted to be engaged by a suitable latch which acts to hold the arm in the full line position, shown in Fig. 2. As shown, such latch consists of a lever 11 mounted to rock about an axis 10 and having its upper end 11 extending longitudinally of the adjacent arm 9. In one edge said lever 11 is provided with a notch 12 adapted to receive a pin or stud 18 projecting laterally from the adjacent arm 9 and said latch lever is so weighted and constructed that it automatically tends to engage the pin 13 and thus hold the lower end of the arm 9 against movement thereby pro viding afirm guideway over which the beams 4 can move.

The beams 4 are successively transferred from the stationary support 3 to the in clined slide or guideway formed by the arms 9 by the action of a series of disks 22 se cured to the shaft 8 and each having a cam shaped periphery providing a member 22 adapted as the shaft 8 rotates to engage a flange of the lowest beam 4 of the series and lift the same over the stops 5 and push it on to the slide 9. As the beam passes down the slide it will strike the upper ends 11 of the latches 11 with sufficient force to rock said latches and disengage the pins 13 from the notches 12. As soon as the arms 9 are thus released they will under the weight of the beam supported thereby rock downwardly about their axial support and the beam will thereby be deposited upon the conveyer rolls 20 in proper position to be fed to the machine 21. The shaft 8 is adapted to be clutched to a suitable driver by means permitting it to make but a single revolution and then be automatically disconnected. This clutch mechanism and the means by which an operator can control the action thereof is illustrated particularly in Figs. 3,

4 and 5 referring to which it will be seen that the clutch 28, comprises a driving member 58 which may rotate constantly and a member 57 which is connected with the shaft 8 by means hereinafter more particularly described adapted to be engaged with said member 58 by the operation of a hand lever 24. Said lever 24 is pivotally mounted at 28 and near its upper end is provided with a latch member 48 having a link 49 terminating in a pin 49 that projects into a slot 49 in said lever and adapted as the latch is rocked to be moved to and from a position where itwill engage with a shoulder 50 on a reciprocating member 51 having its end adjacent the shaft 8 bifurcated and terminating in two forked arms 54, 59, arranged respectively above and below the horizontal plane of said shaft. A stop 52 cooperating with a shoulder 60 on the slide 51 acts to normally hold said slide in the position shown in Figs. 3 and 4 in which position a pin carried by an arm 55 secured on the shaft 8 engages the fork 54. The arm 55 is not connected directly to the shaft 8 but to a threaded sleeve 56 which is revoluble on said shaft and which threaded sleeve is engaged by the hub of the movable clutch member 57. By manipulating the latch 48 to move the pin 49 upwardly in the slot in the operating lever 24 and shifting said lever from the position I, Fig. 8, to the full line position II in said figure, the slide 51 can be rocked sufiiciently to disengage the nose 60 thereon from the stop 52 and by then returning said lever to the position I, the arm 55 will be rocked and the clutch member 57 engaged with the driving member 58. The shaft will thereby be caused to rotate and through the disks 22 transfer a beam 4 from the stationary support to the inclined feed slide 9. As the shaft rotates the pin 53 on the arm will be moved out of engagement with the for: 54 and will subsequently engage the lower fork 59, thereby moving the slide 51 in the reverse direction and bringing the projection 60 in front of the stop 52. The lever 24 is retained in the position I, it being understood that the latch 48 is released and the pin 49 returned to its original position as soon as the slide 51 has been disengaged from the stop 52 at the time of moving the lever 24 from position II to position I. The continued turning of the shaft 8 will carry the pin 58 from the fork 59 and into the fork 54 or the position shown in Fig. 3 and by the engagement of said pin with the latter fork the rotation of said arm 55 will be checked, the slide 51 being at this time held (station ary by the action of the stop 52. Conse quently the sleeve 56 will be turned sufficient to disengage the clutch members 57, 58, and the shaft 8 will be held stationary until the lever 24 is again operated.

In order not to interfere with the feeding movement of the beam 4 by the conveyer rolls, means are provided whereby the arms 9 and latch levers 11 are retained in the position indicated in dotted lines in Fig. 2, which are assumed during the operation of delivering a beam to the conveyer, until said beam has been transported beyond the paths of movement of said arms and levers. The particular stop mechanism employed for this purpose in the embodiment of the invention illustrated is designated as a whole by the reference character 15 and comprises two members 15 pivot-ally mounted on a suitable axis 16 and provided respectively with fingers or tappets 17, 18. Each of said stop members is so weighted as to automatically tend to assume the position indicated in Fig. 2 and a slot 30 is formed through the lower portions of said members and into said slot extends a pin 29 on a swinging arm 27 which is connected by links 25, 26, with the lever 24 or the shaft 28 on which said lever is mounted.

Referring to Fig. 2 it will be seen that when the beam 4 slides down the inclined guideway 9 and strikes the head 11- of the latch lever 11, said lever will be rocked to carry a projection 19 thereon beyond and into engaging position with the tappet 18. During the movement of the latch lever 11 from the position indicated in full lines in said figure to that represented in dotted lines, the tappet 18 will swing about the axis 16 but will immediately return to the position shown in Fig. 2 and by reason of the pin 29 engaging the right hand side of the slide 30 will actto positively prevent return of the lever 11 to its full line position. Similarly the downward movement of the arm 9 will rock the tappet 17 about the axis 16 and such tappet will automatically assume the position shown in Fig. 2 where the arm 9 is prevented from upward movement by reason of the engagement of the pin 29 with the right hand end of the slot 80 in the support for the tappet 17. The parts will be retained in this position while the lever 24 occupies the position I indicated. When, however, said lever is returned to position II the pin 29 will be shifted to the opposite end of the slot 30 and the arms 9 can then return to their elevated position under the action of counter-weights 14 connected therewith and the latch levers 11 will also return to the position indicated in full lines in Fig. 2 in which they engage the pins 13 on said arms 9, as before described.

Instead of employing counter-weights 14 to return the arms 9 to the operative position, said arms may be positively rocked from the shaft 8, as illustrated in Fig. 6. In this construction the rearwardly extend ing member of each arm 9 is connected by a link e with an arm (Z of a bell crank lever fulcrumed at Z) upon a bracket a on the standard (3. The other arm 0 of said bell crank lever extends into the path of rotation of a pin or stud f on the adjacent disk 22. Thereby as the shaft 8 is rotated to remove a beam from the stationary support the arms 9 are positively rocked upwardly into position to form the inclined feed guide and are retained in this position by the latches 11 after the pin f has passed from engagement with the arm 0 of said bell crank lever.
