Specification of Letters Patent. t t d A 1913 ApplicationfiledApril 16,1917. 'SerialNo. 162,588. i

To all whom it may concern: g Be it known that I, PALMER M. OLSON, a citizen of the United States, residing at Fort Ransom, in the county of Ransom and State of North Dakota, have invented certain new and useful Improvements in Wire- Raisers, of which the following, is a specification.

My invention relates to new and useful improvements in an attachment for grain separators and the like, and more particularly to a wire raiser. I

The primary object of the invention is the provision ofan attachment for raising telephone, telegraph, or like wires, whereby a grain separator or like machine may pass thereunder.

A further object isthe provision of means for connecting the attachment to the machine in such a manner that it may be tilted.

A still further object is the provision of means whereby the attachment may be re-,

versed front for rear to allow the raising of wires when the machine is going for ward, or being backed.

With these and other objects in view, the invention consists in the novel details of con-' struction and arrangement of parts which will be more clearly understood from the following description and drawing, in which,

Figure 1 is a side elevation,

gig. 2 a front view of the attachment, an

Fig. 3 a fragmental detail partly in section, showing the hinge and pivot of the attachment.

While my invention is primarily intended for use on a grain separator, it will be understood that it could equally as well be used on a great many other machines and it is not my desire to limit the use of the attachment to any particular machine. I

In the drawing, the numeral 1 broadly indicates the elevating portion of the separator and 2 the weigher. My attachmentis intended to be connected to the elevator and to extend over or house the weigher for the purpose presentlydescribed. A semicircular casting 3 is secured to the top of the elevator by means of rivets 1, or other suitable fastening means and has on the top, a projection 5 and a recess 6 is formed beneath the projection, as is more clearly illustrated in Fig. 3 of the drawing. A forked casting 7 has its shank swivelly mounted in the pro jection 5 by'means of 'a bolt 8, and a nut 9 on the bolt 8 is housed within the recess 6, as more'particularly illustrated in Fig. 3 of the drawing. Sa-id fork supports the arch 11 of the wire guard, the latter comprising a relatively long front arm or nose 10 and a relatively short rear arm or tail 12, which arms converge upward to and merge into the arch as shown. A projection 13 is formed on the underside of the curved portion 11 and said projection is adapted to be received between the arms of the fork 7 and be connected thereto by means of the bolt 14.

Plates 15' are adapted to be clamped around the tubes of the elevator 1, as illustrated in Fig. 1 of the drawing, and a rod 16 is pivotally connected to'the clamp plates and the opposite end is adapted to be re ceived .in the end of a tube 17 which is pivotally connected to the nose 10 at 18. The rod 16 is held in the tube 17 by-means of a thumb-screw 19'which passes through the tube and engages the rod.

A telegraph, telephone or like wire is indicated at 20 and is adapted to engage the nose 10, as indicated in Figs. 1 and 2 of the drawing.

It is thought that from the above detailed description, the advantages of the device and the mode of operation will be clearly understood. As stated in the objects of the invention, my attachment is intended for raising telephone, telegraph or like wires so that a machine, such as a grain separator may pass thereunder. In the past considerable difliculty has been experienced in passing such-machines beneath wires which very often, particularly in the rural districts, hang low and it is to overcome these objections that my invention is intended. When the attachment is in the position illustrated in Fig. 1 of the drawing, when a wire is encountered, it will engage the nose 10 and ride upwardly thereon over the curved arch 11, and thence down the tail 12. By having the latter of such a length as to extend over the weigher 2, it will be seen that the wire will be directly over the weigher andprevented from coming in contact with any portion of the machine. The entire guard their adjusted position. It is often necessary to back the machine and when this is to be done, the clamp plates are removed from one tube and placed on another, as shown in dotted lines, and the whole device may be rotated upon the swivel bolt 8, to assume the position illustrated in dotted lines in Fig. 1 of the drawing. From the above, it will be seen that I secure both a vertical and horizontal adjustment, of the attachment and that the wire will be raised over the machine in such a manner that it cannot be caught in any of the mechanism.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a Wire raiser for separators and the like, the combination with a casting adapted to be mounted on the highest point of the separator, and a fork whose shank is mounted in said casting; of a guard consisting of a pair of upwardly converging arms and an arch connecting them, the arch being pivoted in said fork, and means for tilting the guard on its pivot.

2. In a wire raiser for separators and the like, the combination with a casting adapted to be mounted on the highest point of the separator, and a fork whose shank is swivelly mounted in said casting; of a guard comprising front and rear arms united by Copies of this patent may be obtained (or five cents each, by

an arch, the latter being mounted between the fork-arms, and detachable connections between one of said arms and said separator whereby the entire guard may be reversed, for the purpose set forth.

3. In a wire raiser, the combination with a casting adapted to be mounted on the highest point of a vehicle, and a sup ort mounted in said casting on an upright swivel; of a guard comprising long and short arms converging upward toward each other and integrally united by an arch, and pivotal connections between the under side of the arch and the support.

4. In a wire raiser, the combination with a fork, and means for swivelly supporting its stem at the highest point of a vehicle; of a substantially A-shaped guard, pivotal connections between its apex and the fork, a clamp secured to said vehicle, a telescopic rod connecting said clamp with one of the guard-arms, and means for holding the ele ments of said rod after they have been adjusted.

In testimony whereof I aflix my signature in presence of two Witnesses.
