K. SCHMID SUCTION DEVICE'FOR REMOVING WASTE AND DUST 3119a May 24 1926' Patented May 31, 1927.

UNITED STATES KARL SCHMID, OF MILWAUKEE, WISCONSIN.

SUCTION DEVICE FOR REMOVING WASTE AND DUS'L.

Application filed May 24, 1926. Serial No. 111,268.

This invention relates to air suction clean-- ing apparatus, and especially tothat type used for dust and waste removal in proximity to machinery and the like. lts principal object is to provide a device of this character adapted to be mounted on suitable supports, and when'so mounted to have a range of movement covering an area within the limits of its supporting structurt.

A further object is a means to automatically traverse the receiving element.

These and other objects and features of the device will be fully disclosedin the fol-- lowing specification, and illustrated in the accompanying drawings, in which:

Fig. 1 shows the device mounted on the frame of a loom with the receiver disposed on the traversing mechanism.

Fig. 2 shows a plan view of the apparatus with the upper structure removed above the line 2-2 of Figure 1.

Fig. 3 shows a fragmentary section on a reduced scale, taken on the line 3-3 of Figure 1.'

Fig. 4 shows a fragmentary sectional view on the line 4-4 of Figure 1.

Fig. 5 shows a fra mentary sectional view on the line 5-5 of Figure 1.

Fig. 6'shows the receiver supporting elements havin means to release the threaded members and to secure the said receiver in a fixed position. i

Fig.7 shows a section on the line 7-7 of Fi ure 6.

ig. 8 shows, slightly enlarged; a fragmentary view of the receiver with an adjustable valve mounted therein; the view hemg taken on the line 8-8 of Figure 9. Fig. 9 shows a side view of the receiver and the valve wheel as illustrated in Figure 8.

The component parts of the apparatus may be described as follows:

Referring to Figure 1 of the drawings; a lead screw 10" 'is mounted within suitable supports as shown at 11 and 12. These supports are shown attached to the frame 13 of a loom 14. A receiver su porting element 15 is sup orted in threads engagement on the said ead screw. A vertical member 16 is mounted in the said supporting element. A receiver 17 is secured to the lower extremity of the said element. This receiver is preferably funnel shaped having a wide open lower portion adapted to easily take in such waste material as presents itself; this material being usually in the form of lint. ravelings. particles of woven fabric, dust and the like. A tube connection 18 is mounted on the side of the receiver and to it is' attached the air tube 19 which is connected at its other extremity to a suitable pump, or suction apparatus.

The lead screw is provided with spur gears as shown atr120 ands-i2landrziis driven through the gear 22 which is slidably mounted on the shaft 23 and is actuated by the pulley 2. and the belt 25. The lead screw is driven in reverse by means of the intermediate gear 26 which meshes with the drive gear when the said gear is shifted into line with it. A casing 30 encloses the gear mechanism.

A shiftbar 31 is pivotally secured at its ends to the levers 32 and 33. On the lever 33 is a push finger 34 which serves to slide the gear 22 when required. Contact plun ers 35 and 36 are shdably mounted on t ie supporting frame and serve, when actuated by the

release bars

37 and 38; to throw the bar 31 one way, or the other for the purposc' of shifting the driving gear. A guide rail engages the member 16.

As shown in Figs. 1, 6 and 7 a vertical frame 42 has within the box member 43 opposed

blocks

44 and 45 which are threaded to engage the lead screw 10. These blocks are adapted to shift up or down within the box by means of side pins as shown at 46 and 47 which protrude through slots in the sides of the said box and are in engagement with the inclined slots as shown at 48 and 49. These slots being in the side plates 50 and 51 of the lever 52 which is pivotally mounted on the vertical frame by means of the shaft 53. The lever 52 is offset at the top' and is provided with a handle 54. A slide bearing 40 is located at the top of the vertical frame and is provided with a split bushing ll which bears-against-the rod- 55 .39 extends parallel tothe lead screw and closure member acts against the tubular valve seat 66. It will be seen that the form Of the closure member is such as to prevent the catching of waste particles thereon; it being tapered toward the stem member.

In. operation: the receiver having air suction drawing therethrough, is moved from side to side of the supporting frame by means of the lead screw and the gears are shifted whenever the

release members

37 and 38 come into contact with the push fingers and 36. c

When the mechanism shown in Figures 6 and 7 at the right hand side of Figure 1 is in use; the movement may be stopped at any point by throwing over the lever 52 which will open the blocks as and and at the same time will push down the bevel plate 56 and lock the members in fixed position. Having thus described my invention, What i I claim as new and desire to secure by Letters Patent, is as follows:

1. In an apparatus of the class described,

' a receiver having an air suction tube at tached, and the said receiver secured to supporting elements of the, following construction, a vertical frame, a lever pivotally secured to the said frame, threaded blocks in a box compartment oft-he said frame and having pins protruding therethrough andthe said pins engaginginclined slots in the sides of the said lever, a horizontally split bushing in the upper extremity of the said vertical frame, a bevel plate bearing on the upper portion of said bushing and a shoulder on the said lever adapted to engage the said bevel plate, and the whole supported on a lead screw passing between the said threaded blocks, and itself supported on a suitable frame structure, and a horizontal rod passing through the aforesaid split bushing and supported at its ends by the aforesaid frame structure, and means to rotate thesaid lead screw and means to automatically reverse the rotation thereof. 7

2. In an apparatus of the class described, a lead screw journalcd on the frame of a machine, a carrying member comprising adj ustable threaded block sections mounted on said lead screw and adapted to be moved fromone side to the other of said nachine'" by rotation of said lead screw, a lever operatively connected with said block sectionsfor moving the same apart to disengage the threads thereof from the threads of said lead screw for disconnecting the driving connection between the latter and said carrying member, a receiving member depending min SGHMI
