TWINE ALARM FOR HARVESTERS. APPLICATION mm APR. 10, 1914.
Patented July 27, 1915.
EDWIN SHAVER, OF SOLON'SPRINGS, WISCONSIN.
TVTINE-ALARM FOR I-IABVESTERS.
Specification of Letters Patent.
Patented July 27, 1915.
Application filed April 10, 1914. Serial No. 831,070.
To all whom it may concern:
Be it known that I, EDWIN SHAVER, a citizen of United 'States, residing at Solon Springs, in the county of Douglas, State of lVisconsin, have invented certain new and useful Improvements in Twine-Alarms for Harvesters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to attachments for harvesters and binders wherein twine is used for tying the sheaves and has for its object the provision of a device whereby an audible alarm' will be given when undue strain is put upon the twine, as in the case of tangling and which will thereby warn the operator so that he may remedy the trouble before the twine breaks.
An important object is the provision of a device of this character which will automatically relieve the twine of undue strain sufficiently, to prevent its breaking before the machine can be stopped.
A further object is the provision of a device of this character which will be simple and inexpensive in manufacture, efficient and durable in service, positive in action and a general improvement of the art.
With the above and otherobjects in view the invention consists in general of certain novel details of construction and combination of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.
In the accompanying drawings, like characters of reference indicate like parts in the several views, and :Figure 1 is a side elevation of an apparatus constructed in accord ance with this invention, the bell used herewith being shown in section. Fig. 2 is a section on the line 22 of Fig 1. Fig. 3 is a section on the line 38 of Fig. 1. Fig. 1 is a section on the line 4-4i of Fig. 1.
In carrying out the objects of this invention there is provided a frame which includes a pair of spaced side rods 10 which are preferably termed the friction rods. These rods are secured together at the bottom by a suitable base plate 11 which is provided with a clamp 12 for the purpose of attaching the device to a suitable part of the machine. In this base plate 11 are the guide openings 13 through which the twine is rove. At the upper end of the frame there is provided a top plate 14 secured to the side bars 10 and extending upward from this top plate 14: is a standard 15 having a curved upper end 16 whereon is supported a bell 17. There is also mounted on the member 14- a pawl 18 which is pivoted to this member and has a tooth both sides of which are inclined as clearly shown in Fig. 1. end of this pawl 18 there is provided a plate 19 which has a slot 20 therein through which the standard 15 passes, the plate being held. in guided position on said standard by means of a pair of spaced pins 21.
Pivoted to the member 14: as at 22 is a le ver which is connected to the pawl 18 by means of a spring 23 and this lever 22 may be adjusted to increase or diminish the tension of the spring by means of a thumb screw 24 passing through the lever and bearing against the standard 15. This plate 19 above referred to constitutes the knocker for the device so that as the pawl 18 is oscillated the bell is struck first on one side and then on the other.
Slidably mounted on the rods 10 is a frame 25 wherein are mounted friction shoes 26 which bear against said rod and are held apart by means of a suitable spring 27 so that the rods are clamped between the sides of the frame and said shoes. This frame is provided with a suitable opening 28 to receive the twine after it is led through one of the openings 13, the twine being then. led back through the other opening. On the frame 25 is fixed a bar 29 provided with'a series of notches 30 arranged to engage the pawl 18 when the device is set, and to be successively engaged by said pawl upon the alarm being given.
In setting the device the frame 25 is pushed as far upward as it will go so that the pawl 18 engages in the last notch. This thread is then rove through the opening and the binding operation is proceeded with. Then the twine becomes tangled and the tension increases the frame 25 will be pulled downward by this increased tension and consequently the pawl 18 will be oscillated about its pivot. This causes the knocker 19 to reciprocate and consequently ring the bell. At the same time the downward movement of the frame 25 relieves the tension so that the operator is enabled to stop his machine and untangle the twine before it breaks.
On the upper There has thus been provided'a simple and efiicient device of the kind described and of the character specified. t
It will be obvious that many minor changes may be made in the form and construction of this invention without departing from the material principles thereof. It is not therefore desired to confine the invention to the exact form herein shown and described, but it is wished to include all such as come properly within the scope claimed- Having thus described the invention, what is claimed as new, is
A device of the class described comprising spaced rods mutually connected at their ends, a frame slidably mounted on the rods, friction shoes mounted in the frame and engaging said rods, spring means forcing said shoes into engagement with the rod, said frame being provided with an opening through which is trained a binder twine and whereby a predetermined tension arising in said twine will slide the frame on said rods, and means operated by the sliding of the frame for sounding an alarm.
In testimony whereof, I affix my signature, in the presence of two witnesses.
EDVYIN SHAVER.
