in Germany April 9, B1934 1 o -(oi. 103-.-126)- This invention relates to a gear pump for delivering spinning solution to artificial silk spinning machines. It is known in such pumps to provide the driving shaft with a collar and to in a bore in the clamping element. This collar is, however, provided on the inner side of the clamping .element between the same and the front plate of the pump in order to thus prevent the spinningv solution from enter- 1o ing the bearing ofv the driving shaft and a hardening of this solution by inflowing air. Experience has shown that in the arrangement referred to spinning solution still penetrates into the bearing. Moreover a separate lubrication is necessary for the driving shaft, which adds to the cost of the-pump. The pump must be dismantled for the removing ofthe driving shaft because the collar of the shaft is arranged within the'pump. It is also known to utilize the spin 2o ning solution for lubricating the driving shaft and. to close the hearing at its outer side by means of a stufling box.
The present invention consists'in arranging the recess designed to accommodate the collar. 25 of the driving shaft on the outer side of the clamping element and to cover this recess for cap nut without stufling box; to hold the collar.
By this arrangement thebearing of the drivbut a stufling boxis omitted and nevertheless any air admission is excluded. The driving shaft can be removed after unscrewing the cap nut without dismantling or the pump, which rep-' 35 resents a considerable simplification.
' An embodiment of the invention is illustrated by way ofexample in the only figure of the accompanying drawing which shows a pump part,- ly in side elevation and partly in section.
' The pump, comprising a clamping element I and pump plates 2, I, 4 and i, carries in its ining shaft is lubricated by the spinning solution, j,
-.sion and preventing ingress of air The collar l0 prevents air from coming into' contact with the spinning solution.
I claim:--
A gear spinning pump, comprising in combination, a clamping element having a lateral extension with a bearing bore in the clamping element extending from a point adjacent the inner end of the clamping element through the lateral extension, said bore being of constant diameter throughout its length, the outer end of the clamping element extension having an annular recess therein surrounding the bearing bore, pump plates on the inner side of said clamping element, an intermeshing driving gear and driven gear arranged between said plates, a short shaft-mounted in said plates and carrying said driving gear, a driving shaft dimensioned for journalled mounting in thebearing bore of said the extension, a collar rigid with the driving shaft and fitting in said annular recess and a cap nut surrounding the outer projecting end of the shaftand screwed onto said lateral extension to maintain said collar in said recss whereby thespinning solution may flow through the bearing bore for lubricating the driving shaft and said collar acting to prevent the escape of spinning fluid at theouter end of the lateral extenat the outer end of the lateral extension.
