WILHELM TROELLER, OF FRANKFORT-ON-THE-MAIN, GERMANY.
IVLEANS FOR ATTACHING STIRRING-ARMS TO SHAFTS IN IlIECHANICAL ROASTING- FURNACES.
To all whom it may concern:
Be it known that I, WVILHELM TnoELLnR, a subject of the German Emperor, and resident of Frankfort-on-the-Main, Germany, have invented certain new and useful Improvements in Means for Attaching Stirring-Arms to the Shafts in Mechanical Roasting- Furnaces. of which the following is a specification.
My' invention relates to apparatus, and more especially to mechanical roasting furnaces, in which stirring-arms are removably fixed in rotating-shafts, the object of the invention being an improved method of attaching said stirringarms in the shafts. The advantages of the present invention over the known devices consist chiefly in the fact, that the stirring-arms areeasily to be in serted in and removed from the openings provided in the shaft to receive the rabblearms, and that for securing the arm in the shaft in order to prevent it from being moved in radial direction it is sufficient to operate a slight rotation of the arm or of the shaftopening in a horizontal plane.
Figure 1 is a horizontal section of the shaft with the stirrer-arm. Figs. 2 and 3 are modifications of the device shown in Fig. 1.
According to the method illustrated in Fig. l the shaft a is provided in the known manner with a transverse passage at each hearth of the furnace. stirring arm 0 to be coupled with the shaft, is formed a projectin lug (1 adapted to engage over the back e ge of the passage and thus to prevent the movement of the stirringarm in a radial direction outwards.
In order to enable the end I) of the stirringarm with the lug d to be pushed through the passage, the end I) of the stirring-arm is tapered as shown at c. On the side of the end 6 opposite to that occupied by the lug d, a second lug f may be arranged, formed for the purpose of preventing the stirringarm being pushedtoo far in the opposite direction, that is to say inwards.
The arm can be installed in the position wherein the lugs 61 and f prevent said arm from being pushed in either radial direction by entering the front end in the posi tion shown in dotted lines and by then bringing the arm in the position shown in fullv lines by means ofa rotation in a horizontal Specification of Letters Patent.
Application filed. July 17, 1907.
On the end 6 of the plane, or, when the shaft rotates in the di- Patented Nov. 24, 1908.
Serial No. 384,216.
rection indicated by the arrow, the stirring arm places itself automatically in the position shown in full lines.
According to the modified method, illustrated in Fig. 2, the passage is furnished at that end, where the stirrer arm is inserted, with a wedgeshape enlargement 9. By this construction, it is possible to shorten the tapered portion 6 of the end I) of the stirringarm and so to increase the strength of that part and to diminish the risk of breakage. Moreover, by the enlargement of the entrance of the passages the insertion of the stirring-arm and the pushing of the stirringarm into position is facilitated. The installation of the stirring-arm in the fixed position is effected in a manner similar to that described with reference to Fig. 1.
Fig. 3 illustrates the application of the invention when two stirring-arms disposed dia metrically opposite one another are mounted in one and the same passage. In this case, projections (or recesses) are provided opposite one another on the side walls of the passage, behind which (or in which) engage the lugs 03 of the stirring-arms. As illustrated in Figs. 1 and 2, the ends Z) of the stirringarms are formed with taper portions 6 which enable the stirring-arms to be inserted in or withdrawn from the passage. The passage may here also be provided with an enlargement such as g, Fig. 2.
Having now fully described my said invention what I claim and desire to secure by Letters Patent is:
l. The combination of a shaft provided with a transversely disposed opening, and a stirring arm having a portion adapted to enter said opening and relatively reduced 1n size with respect thereto, said portion having oppositely projecting parts spaced apart from each other and engaging said shaft and serving to prevent longitudinal and permit lateral movement of said portion in said passage.
transversely disposed opening provided with a lateral extension thereby forming one wall composed of two angular engaging portions and a straight opposite wall, and a stirring arm having a portion adapted to enter said opening and reduced throughout a part of its length with respect thereto, one edge of said portion being adapted to engage either of said angular walls and the other edge of said portion engaging a part of said straight wall, said portion having oppositely disposed parts engaging peripheral portions of the shaft at points opposite the centers thereof to prevent longitudinal and permit lateral movement of said arms.
4. In mechanical furnaces, the combination of a shaft having transverse openings, and of stirring arms adapted to enter and to be fixed in said shaft-openings, the portion of said stirring-arms which enter the shaftopenings being laterally reduced in size on one side and each provided with a lateral projection on the opposite side, the projection engaging behind the edge of the shaftopening to limit movement of the arms in a radial direction. I
5. In mechanical furnaces, the combination of a shaft having transverse openings, and of stirring arms adapted to enter and to be fixed in said shaft-openings, the portion of said stirring arms which enter the shaftopenings being laterally reduced in size on one side, and each being provided on the same side with one lateral projection and on the opposite side with another lateral projection, the projections engaging behind edges of the shaft-openings to limit movement of the arms in opposite radial directions.
6. In mechanical furnaces, the combination of a shaft having transverse openings, and of stirring arms adapted to enter and to be fixed in said shaft-openings, said shaft openings being outwardly enlarged at the end at which the'st-irring arms enter, and the portions of said stirring arms which enter the shaft-openings being laterally reduced in size on one side, and each being provided on the same side with one lateral projection and on the opposite side with another lateral projection, the projections engaging behind edges of the shaft-openings to limit the movement of the arms in opposite radial directions.
In testimony whereof I have hereunto set my hand in presence of two witnesses.
