surronr-srnv non ENGINE-PUMPS.

To all whom it may concern:

Be it known that I, CHARLES H. Mouse, a citizen of the United States, residing :at Montpelier, in the county of Blackford and State of Indiana, have invented certain new and useful Improvements in Support-Stays for Engine-Pumps, of which the following is a specification.

This invention relates to improvements 1n engine pump brackets that is to say-brackets or supports for fastening the pump at its position on the engine.

The style of engine pump for which this invention is intended is that shown in the drawings forming a part of this application, and'comprises a barrel A of brass tubing screwed into the body B of the pump head at the point where the barrel is commonly located. The body of the pump is of cast iron of the general form and bulk as shown and the plunger 0 is operated in said barrel in the usual manner.

For the purpose of attaching the pump to the engine at the bosses D (always provided but at locations varied slightly from those shown, on the different makes of engines) clamp socket brackets E of the make shown at Figure 7 are used. The socket of this style of bracket is adapted to fit closely over the barrel of the pump (as shown in Fig. 6) and to be clamped securely thereon by a bolt passed through the ears Gr. A wing H is formed on said bracket having slot K therein through which a bolt may be introduced to secure the said bracket to the engine. It is apparent that adjustment of the location of the barrel in direction transversely of the bracket is possible. i

Pumps constructed along the lines herein shown, by reason of the few parts and of their simplicity of construction, are economical of manufacture, and are easy to'install. Thefeature of the plain brass barrel and of its simple threaded connection to the pump head is desirable on account of the economy possible in constructing the pump. This pump, constructed as shown, is extensively used as a part of steam engines performing duty in oil fields and where a cheaply constructed pump is required,-and,'

where, at the same time, the duty imposed on the pump is heavy and almost continuous service 1s common.

Specification of Letters Patent.

Patented Dec. 17, 1918;

It has been demonstrated that the operation of. this pump has been accompanied by an occasional failure of'the pump barrel A at the threaded connection with the pump head, such failure, consisting of a. checking or partial rupture of the brass barrel between the bracket location and the pump head. Of the total number of these pumps constructed and used, there has been comparatively such a very few in which the above fault has developed, that considering the increasein cost of production incident to modification of the pump head and of the barrel, in order to change this detail of connection of these parts, .it has been consideredlnot practicable to change this detail of construction. .That isto say, that the class of trade to which this pump is a com modity'would rather consider the use of a a reinforcing or bracing device whereby the portion of this pump including the rear end of the brass barrel and the boss portion of the pump head may be braced or stayed so that possibility of flexure or checking of the barrel may be avoided.

In carrying this invention into effect I provide the new construction, combination and arrangement of parts shown in the accompanying drawings, and my invention isembodied in the combination support and stay device illustratedand described herein.

In the drawings the difiierent parts of the device are represented by suitable characters of reference applied thereto.

Fig. 1 is a front view of support-stay device.

Fig. 2 is an end view as seen. in direction of the arrow 2 in Fig. 1. 1

Fig. 3 is a perspective View of thesupport my improved element.

class herein referred to disposed at position in readiness to have applied thereto my im proved support stay device.

Fig. 7 is a perspective view of a standard form of bracket support.

My invention comprises a stay member adapted to co-engage the boss B of the pump head, and the base portion A of the barrel, in combination with a bracket or support element, the stay member and support member being so constructed, combined and arranged, that by the tightening of the securing bolt into the engine boss the support and stay member will be tightened to coengagement with the barrel and the pump head. I

This stay member 1 has its body portion of cylindrical form as shown in Fig. l and is of two piece construction, the meeting wall edge of one piece having the tooth 2, andthe wall edge of the other piece having the recess 3. By the coengagement of this tooth and recess the two body/pieces are mutually retained. connected together and in alinement. This stay member is made as light in weight as may be, consistent with proper strength and proportion. its internal diameter is slightly larger that the outside diameter of the barrel A. A clearance distance or space a between the body pieces is provided, the purpose of which will presently be described. The head 5 has a bore 6 of diameter substantially the same as the diameter of the boss B of the pump head. On theinternal face at the rear end of each of the'stay member body pieces is provided a heel 7 whose face is adapted torest directly inicontact with the surface of the pump barrel A. 0n the external face at the rear end of one of the body pieces is: provided an ear 8 the function of which will be later referred to.

' From the description thus far, it is apparent that when the body pieces of the stay member are disposed at position, the face of the bore 6 in head 5 is in engagement with the boss 13 of the pump head, and the heels 7 are in engagement with the surface ofthe pump barrel A, there being a clearance 9cbetween'the internal face of the stay member and the surface of the barrel, and there being the clearance space 4 between the edges of the body pieces.

The meansto accomplish'the engripment and drawing together of the body pieces, and at the same timeto afford a stout support or bracket for same, consists of a member shown in perspective, in'Fig. 3. This support member 10 may be made of cast brass, or, it may preferably be made of iron or steel bar metal. The body portionis of curvature to conform to the external face of the stay member; the back leg 10 is bifurcated and is adapted to be disposed at position against the face of the engine boss D. The frontal leg 10 also is bifurcated and occupies position a slight distance apart from the back leg there being the clearance space ll between the said legs.

To place the two above described members in connection with each other, the stay member is slipped transversely through the opening in the support member, the ear 8 of" the stay member passing through the space 12 in the support member. Then by moving the stay member rotatively to a position so that the ear 8 is out of registration with the space 12, it will be seen that the several parts, while retained together as an entirety for convenience in handling and for shipment, it is easy to take them apart preparatory to installing the same for use, as will be presently described.

My invention in readiness for the market, is in the assembled form as shown in Fig. 1, and is designated as a support-stay for en gme pumps. 1

The stay member is turned to position to permit the ear 8 to pass through the space 12, and is withdrawn from the support member. The support member isthen placed at loose position on the pump barrel. The pump head and barrel assembly is then disposed at position adjacent to the bosses D therefor, the support member hanging loosely on the barrel, as shown by the dotted lines in Fig. 6. The regular bracket support shown at Fig. 7 may then be placed at position and fastened by bolt L. The body pieces ofthe stay member are then placed at the dotted line location as shown inFig. 6,;the bore 6 of the stay member head engaging the boss B of the pump head, and the heels 7 engaging the pump barrel. The support member is then moved along the barrel to thestay member, the latter being shifted rotatively until the ear 8 is in registration with the space 12 which permits the passing of the support member to position in engagement with the stay member. After 11.0 the adjustment of the support member at registration with the bolt hole in the engine boss, the anchor bolt M is screwed into place.

By screwing in the bolt, the front le 10 is drawn toward the back leg 10 sufliciently that with the constricting of the body portion 10, the body pieces 1 of the stay member are drawn toward each other; the heels 7 acting as fulcrums, whereby the engripment of the body portion 10 of the support member exerts a powerful leverage and the bore of the stay member grips the boss B of the pump'head so tenaciously that the pump head and the barrel are substantially reinforced. I With this arrangement of stay and support, the possibility of flexure or ,checking of the pump barrel is avoided.

A support-stay device constructed in accordance with my invention as ]l1Si3 descrlbed and illustrated, is simple in construction, economical of manufacture, ands:

easy to handle and install. As an accessory or repair device for pumps of the class described it is desirable as a reinforcing or strengthening element to be used Where the pump is to be subjected to long continued continuous unusually heavy duty.

The maximum distance between the pump head and the forward boss D of the engine, to be dealt with in the use of this class of pump, is that shown in Fig. 6. As will be seen by reference to Fig. 4c the length of stay member is arranged to be available for this maximum. By reason of the support member being adjustable, the device obviously is equally available for varying distances between the pump and boss.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A support stay device of the kind described, comprising a pump barrel, a pump head, a divided stay member having a bore slightly larger than the diameter of the barrel, and an open head to engage the boss of the pump head there being a heel in the bore of said stay member at its rear end to engage the pumpbarrel, and clamping means carried by the stay member to constrict the latter to tight cooperative engagement with the pump head and barrel.
