Description

Feb. 13, 1934. w. R RHINE EXTENSION SPOUT OR CHUTE Filed Aug. 26, 1933 Patented Feb. 13, 1934 UNITED STATES PATENT OFFICE The present invention relates to chutes or extension spouts, and while it is particularly useful in connection with spouts for grain elevators it is equally useful, as will be obvious, in many 5 other relations where extensible spouts are desirable or required.

In grain elevators and the like a part of the bins or storage spaces are some distance above the floor or ground level and are usually pro- 19 vided with a turnhead or angular spout for the delivery of the contents of the bin. It is customary when removing grain or other material from such bins to attach an extension spout to the angular or turnhead spout. While various means have been devised for attaching the extension spouts to the turnhead, all have been found defective for one reason or another, and according to the manner in which this is now usually done one man holds the extension spout in place while another climbs a ladder and secures it in position by means of a chain on either side thereof. This is a laborious and slow operation and results in great loss of time and labor when shifting from bin to bin.

It is an object of the present invention to provide an improved chute or extension spout embodying means whereby it may readily be attached to and detached from an overhead angular spout by a single operator standing on the floor or ground level.

Another object is to provide a chute or extension spout with means for 'quickly attaching it to an angular spout and in which the said means may be retained in inoperative position until the chute has been placed in operative relation with respect to the angular spout.

Other objects, advantages and useful applications of the invention will suggest themselves upon reference to the following detailed descrip- 40 tion and the accompanying drawing wherein:

Fig. 1 is a side elevation of an embodiment of the invention attached to a conventional turnhead spout.

Fig. 2 is a side elevation showing in full lines the securing member retracted and in dotted lines its position in full release.

Fig. 3 is a front elevation with the securing member in extreme projected or released position.

Fig. 4 is a fragmentary view similar to Fig. 3 but showing a slightly modified form of the pivotal support for the clamping ring.

Referring in detail to the drawing, 1 indicates a conventionaltubular turnhead spout having an upper vertical portion 2 communicating with a bin or the like and a lower discharge portion 3 which is disposed at an angle to the section 2.

The chute or extension spout 4 which may be of tubular form has a curved, preferably ringshaped, attaching member 5 pivoted on or in proximity to the upper end thereof. The ring 5 as shown is formed with straight portions 6 and between these portions is deformed to provide a radially projecting loop 7 which will be referred to hereafter.

For the purpose of mounting the ring 5, a plate 8, Figs. 1 to 3, is riveted or otherwise secured to the upper end of the chute 4, said plate having the upper end thereof bifurcated and extending beyond the end of the spout, the furcations being rolled back upon themselves to provide journals 9 for the straight portions 6 of the ring 5.

The looped projecting portion 7 of the ring 5 extends beyond and between the pivot provided by the journals 9 and may be turned up slightly at its end to which may be secured means for moving the clamping member 5 into clamping position, preferably, as illustrated, one end of a contraction spring 10, the other end of which is anchored to the body of the extension spout 4 through a bracket 11. The spring 10 normally tends to project the ring to a position substantially parallel with the longitudinal axis of the chute as shown in dotted lines in Fig. 2.

A suitable chain or other flexible member 12 is secured as at 13 to the ring 5 at a point opposite the pivots 9 for the purpose of retracting and holding the ring concentric with the top of the chute when engaging and disengaging the latter from a turnhead. A latch 14 of any suitable form for engagement with the chain 12 serves to lock the ring 5 in retracted position as shown in Fig. 2.

The ring 5 may be provided with a rubber, fiber or other covering 15 of friction material throughout a greater portion of its circumference to assure a firmer grip on the turnhead spout.

In order to make a single size chute adaptable to turnheads of varying circumference, I provide means for varying the efiective size of the ring 5. The means shown is in the form of a set screw 16 which is threaded through a block or plate 17 secured between the legs of the loop 7 as shown in Fig. 3. As the inner end of the screw 16 forms a bearing for engaging one side of the turnhead, it 105 will be readily apparent that adjustment of the screw will make an extension spout of one size capable of variable application.

The upper edge of the spout 4 may be formed or provided with a flange or collar 18 against which 110 the clamping ring rests when fully retrieved and in non-clamping position.

In operation, the screw 16 being properly adjusted according to the size of the turnhead, the ring 5 is held in retracted position as shown in Fig. 2 by pulling down on the chain 12 and engaging the latter with the latch 14. This leaves both hands of the operator free to manipulate the chute which is then raised and slipped up over the lower end. 3 of the turnhead spout 1 as far as it will go and with the pivots 9 facing the inside of the bend of the spout. While held in this position, a slight pull on the chain 12 will disengage it from the latch 14 so that when released the spring 10 will throw the ring 5 over the outside bend in the turnhead spout and into frictional clamping engagement with the vertical portion 2 thereof, thereby firmly securing the chute in position.

It will be noted that the diameter of the ring 5 is sufficiently large to permit the ring to clear the outer edge 19 of the elbow in its upward movement. Although the ring 5 is shown as continuous, it need not be so, as clamping can be effected by two curved arms which are joined at the pivot end and therefore move in unison although they do not meet to form a complete ring. If such form is used, the pull-chain should be connected to the ends of both arms.

When it is desired to detach the chute the ring 5 is retracted by pulling on the chain 12 and the chute may then be slidably disengaged from the turnhead. Both operations can readily be performed by a single operator standing on the floor or ground below the overhead spout.

Where the extension is to be used upon a number of spouts having the same size or substantially the same size, the adapter member l6'may, of course, be omitted. Also, the journal or other support for pivoting the spout-engaging member 5 may be secured to or form a part of the extension 4 or the ring 18. In the modification illustrated in Fig. 4 the ring 18 carries the journal members 9 in which the spout-engagingmember 5 turns in movement to and from its clamping position.

While the invention in its preferred embodiment has been illustrated in connection with a chute or extension spout, it will be understood that its use is not restricted thereto; also that the word tubular as herein employed is not to be restricted to cylindrical shapes, since the invention is useful on spouts or the like which are of non-circular cross-section.

Various changes in the details of construction and operation may obviously be made without departing from the spirit of the invention or the scope of the appended claims.
