VENTILATION AND DUST REMOVAL SYSTEMS 0F RING SPINNING MILLS Filed Jan. 22, 1957 2 Sheets-Sheet 2 United States Patent VENTILATION AND DUST REMOVAL SYSTEMS OF RING SPINNING MILLS Richard Sutcliife, Holcombe Brook, near Bury, England, assignor to Textile Air Systems Limited, Radcliffe, near Manchester, England, a British company Application January 22, 1957, Serial No. 635,291

1 Claim. (Cl. 57-56) In spinning mills it is usual to arrange the driving motors for the ring spinning machines at the same end of all the machines which are in line side by side and this causes a concentration of generated heat at the ends of the frames where the motors are situated which upsets the heat balance in the spinning rooms. In addition, at the same ends of the machine are situated the electric motors which drive the suction fans of the suction system which has suction nozzles adjacent to the delivery rollers of the machine in order to draw into the suction system any broken ends which might otherwise cause breakage of adjacent yarns. Further where an overhead cleaner travels along one side of each spinning frame and reverses its motion by travelling around the end of the machine and moving along the other side, there is found to be an accumulation of dust and fluff at the end of each frame.

The object of my present invention is to provide means for obtaining a more uniform distribution of heat in a spinning room and to prevent dust and fluff becoming dispersed in the atmosphere of the spinning room.

The invention consists in a ventilation or dust removal system of a ring spinning mill in which the driving motors for the ring spinning machines are at the same end of each machine as a broken end suction unit of such machine comprising an open exhaustion cowl or hood connected to the ventilation control arrangements of the spinning room positioned over the discharge orifice of the broken end suction unit of the spinning frame with a gap between the cowl or hood and the discharge orifice so that said cowl or hood receives the discharge therefrom and can draw air from around the motor or motors driving the spinning frame so as to exert a strong cooling action on the motor or motors and evacuate any dust or fluff which tends to accomumulate at the frame end.

My improvement by providing a strong air circulation where there is a concentrated generation of heat in each spinning room and by utilising such air circulation for dust removal purposes also, produces better conditions in spinning rooms than is at present obtainable.

Referring to the accompanying explanatory drawings:

Figure 1 is a diagrammatic view showing the application of our invention to four ring spinning frames.

Figure 2 shows a modification where an overhead travelling cleaner travels back and forth over a spinning frame.

In Figure 1, 0 indicates the discharge pipes of the fans k driven by the motors m, the fans drawing from broken end suction units of the four spinning frames represented diagrammatically. The driving motors of the spinning frames are indicated diagrammatically at b, these being situated at the same end of each frame as the broken end suction units before referred to. In accordance with the present invention I provide open exhaustion cowls or hoods c which not only draw air from the several discharge pipes a but also draw air from around the motors so as to cool the same and evacuate any dust or fluff which tends to accumulate at the frame ends. It will be seen that there is a gap between each hood c and each discharge pipe a and that the cross sectional area of the inlet to each hood is greater than the outlet from each discharge pipe a.

The pipes d from the hoods 0 lead to the usual ventilation control arrangements of the spinning room which allow air to be discharged to atmosphere and fresh air drawn in to replace the discharge if the room temperature rises unduly, the air pressure in the spinning room being also maintained substantially constant. The air delivered in to the spinning room is diffused through fabric filter tubes.

Where an overhead cleaner represented diagrammatically at f in Figure 2 is employed over a spinning frame, the pipes a of the broken end suction units are bent as shown and the cowl or hood h of the receiving portion of the exhaust branch d is spaced from the pipe a and its end [1 is made larger than the end i of the discharge pipe a' so that there is in addition to exhaustion of the pipe a, an intake of air from aroundthe frame end, which keeps the main driving motor or motors cool and prevents the accumulation of dust and fluff at the end of the machine.

What I claim is:

A series of ring spinning machines which are in line side by side, a driving motor at one end of each machine, the motors of the series being at the same end of all the machines, suction nozzles arranged along each machine to draw into the suction system broken yarns produced in the machines, suction fans arranged at the same ends of all the machines for drawing air and broken yarns through the suction nozzles, electric motors driving said suction fans and located in the machines at the same ends as the machine driving motors, a discharge pipe on the end of each machine for the delivery from the said suction fans, an open exhaustion hood of a main exhaustion system extending over but at a distance from each discharge pipe, the space between each hood and discharge pipe drawing air also from around the machine driving motor to cool same and evacuate any dust or flufi tending to accumulate at each machine end where the machine and fan driving motors are situated.
