PUMP HANDLE AND Tor.

Specification of Letters Patent.

Patented Dec. 29, 1908 Application filed .March 22, 1904. Serial No. 199,326.

To all whom it may concern:

Be it known that I, CLAYTON L. KENYON, a citizen of the United States, residing at Tama, in the county of Tama and State of Iowa, have invented certain new and useful Improvements in Pump I-Iandles and Tops, of which the following is a specification.

The objects of my invention are to provide an improved pump handle and top made of sheet metal so that it cannot be easily broken and also. to provide a pump handle and top so arrangedthat wear between the moving parts thereof is reduced to a minimum and when wear takes place, the parts may be readily, quickly and easily readjusted to take up wear and to prevent lost .motion and rattling between the movable parts.

My invention consists in certain details in the construction, arrangement and combination of the various parts of the device, Whereby the objects contemplatedare attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which 1 Figure 1 shows a perspective view of a pump stock with my improved handle and top applied thereto as in practical use. Fig. 2 shows an enlarged detail sectional view through the upper end of the pump top and rod. Fig. 3 shows a longitudinal sectional view through the link and connected parts. Fig. 4. shows a perspective view of a pump top, handle and rod of modified form. Fig. 5 shows a transverse sectional view through the line 55 of Fig. 4. Fig. 6 shows a transverse sectional vi'ewthrough the line 6'6 of Fig. 4. Fig. 7 shows a transverse sectional view through the line 77 of Fig. l. Fig. 8 shows a transverse sectional view through the line 88 of Fig. 4. Fig. 9 shows a modified form of the pump handle, and Fig. 10 shows a transverse sectional view of a modified form of handle.

Referring to the accompanying drawings, I have used the reference numeral 10 to indicate the pump stock. Near the top of the pump stock is an annular rounded rib 11 for purposes hereinafter madeclear. The pump top is formed complete of two pieces of sheet metal. These pieces are counterparts of each other except, of course, that one is formed for the right and the other for the left side. Each part comprises a segmental collar piece 12 provided with an outwardly projected rounded rib 13. Said rib designed to receive the annular rib 11 and the body;

' exterior of the pump stock.

portion of the collar is designed to engage the By forming the rib 13 to receive the rib 11 of the pump stock, I provide means by which up and down movements of the collar relativeto the stock are prevented. At the front'of the collar 12 is a forwardly projecting lug 14 and at the rear of the collar 12 is a rearwardly projecting lug 16. Near the inner end of the part 16, I have formed an upright 18 extending upwardly a considerable distance, then curved laterally at 19 and then curved inwardly at 20 over the center of the collar 12 and at the end of the curved portion 20, I have formed the arm 21. This arm 21 is provided with a laterally projecting portion 22 having square shoulders on its mner surface.

For strengthening the part just described, I have formed near the top of thecollar'l2, a rounded rim 23 which rim is continued u wardly to the top of the part 18. I have aso provided an outwardly projecting rib 24 extended along the outer edges of the part 18 and I have provided for strengthening the part 22 by forming the rib 25 therein, which rib projects outwardly, as clearly shown in Fig. 1. When the top sheet metal top parts, just described, are assembled, the top of the pump stock is surrounded by the collar formed by the parts 12 and a bolt 26 is passed through the opening in the lugs 14. to adjustably secure them together and a bolt 27 is passed through the lugs 16 to adj ustably secure them together. The upright ortions 18 stand spaced apart a considera ledistance for the reception of the handle and link hereinafter described.

The said (parts, however, come together at the curve part 20 and the arms 21 are connected together by the bolts 28. The laterally extended portions 22 of the arms 21 are designed to receive a rectangular bearing block made of cast metal to receive the pump rod and to permit it to slide freely through said'bearing. This bearing block is indicated by the numeral 29 and is provided with a rectangular opening and also with outwardly projecting flan cs 31 at its upper and lower ends which anges' overla the tops of the parts 22. I have rovi ed for supporting the pump handle etween the rearwardly projecting lugs 16 by providing a link composed of two sheet metal parts. Each part having a straight provide with an opening to receive the 7110 central'portion 32, an upper end portion 33' handle bolt and the parts thereof are spread and a lower end ortion 35 having an opening for a bolt and the parts thereof are also spread. Said body portion 32 is firmly connected together by the rivets 87. The lower end of said link is inserted between the extensions 16 and the bolt 27 is passed through the lugs 16 and the link and forms a pivot for said link and the upper end of the link is capable of moving in and out between the uprights 18.

The handle is formed complete of a single piece of sheet metal. The central portion of the handle is a proximately oval in section as shown in ig. 5. Near the fulcrum point of the handle, the sides are relatively wide apart and a fulcrum strip 38 is secured by rivets 39 to the outer surface of the handle, the lower ends thereof extend downwardly below the handle. To connect the fulcrum piece 38 with the top of the link, I insert a sleeve 40 through the upper ends of the link and then pass a bolt 41 through the fulcrum strip 38 and through the sleeve. 40. and provide a nut 42 for the end of the bolt. In this way, the said sleeve holds the lower ends of the fulcrum stripspaced apart to give a maximum resistance to lateral movement of the pump handle and the said parts being made of sheet metal are yieldingly held together so that they will not rattle when the pump handle is operated. Furthermore in case wear should take place, it is only necessary to adjust the nut 42 thus bringing the parts closer together and take up the wear and thereby preventing the parts from working loose or rattling.

The inner end of the pump handle is formed with fiat, parallel sides and the end portions of the metal are doubled inwardly and then backwardly parallel with the sides forming the reinforcing pieces 43. I connect the inner end of the handle with the pump rod, as follows The numeral 44 indicates the pump rod which is passed through the inner end of the handle between the reinforcing sides thereof. I ivot the handle to the pump rod by placing a s eeve 45 through the pump rod 44 and allowing the ends of the sleeves to project slightly beyond the sides of the ump rod. I then place a bolt 46 through t e sides of the ump andle and through the sleeve and p ace a nut 47 on one end of the bolt then by drawing up the nut, the sides of the pump handle are yieldingly held against the ends of the sleeve. Thus the wear takes place between the pump rod and the sleeve and is not thrown upon the bolt and if the parts should become loose, the wear may be taken up by adjusting the nut 47.

In the modified form shown in Fig. 9, I have. provided a wooden handle 48 inserted in the end of the sheet metal handle and held in place by rivets 49.

In the modified form shown in Fig. 10, I have shown a pump handle made of two pieces of sheet metal forming a pump handle substantially oval in cross section. The parts being divided at their top and bottom and the edge portions overlapping each other. The said parts being connected by a rivet 50 extended through the overlapping ends above and below. Said rivet provided with heads 51 at its ends which heads prevent the edges of the )arts from springing outwardly while the resi iency of the sheet metal of which the 'parts are formed prevents them from springin inwardly.

n the modified form shown in Fig. 4, I have shown a pum) top made of a single piece of sheet meta designed to be used in places where the pump rod extends only to the pump handle and does not project above it. This top comprises a collar 52 formed in the central ortion of the piece of sheet metal. The ends 0 the sheet metal brought together and projected upwardly at 53 forming a standard and the end portions doubled outwardly and then backwardly over the sides at 54 to reinforce and strengthen the ends of the upright. An 0 )ening is formed in the said overlapping ends. When this )ump top is used, I connect it with the handie by providing a fulcrum strip 56 riveted to the pump handle and having its lower ends inclined inwardly and then upwardly at 57. The end portions being spaced apart slightly from the sides of the fulcrum strip. I then. place a sleeve 58 in the opening 55 and pass a bolt 5?) through the fulcrum strip and through said sleeve and lace a nut 60 on the end thereof, as clearly s iown in Fig. 7.

In practical use, I attach the pump top to the pump stock by placing the sides of the collar 12 around the )ump stock and passing a bolt 26 through the extensions 14 at the front. I then connect the link and the handle, as shown in Fig. 3 and then connect the link with the projections 16 by means of the bolts 27. I then pass the pump rod 44 through the bearing block 29 and pivotally connect it with the handle, as shown in Fig. 1. The sides of the pump top are strengthened and reinforced by the

ribs

13 and 23 and the flange 24, and the top is prevented from up and down movement on the pump stock by the rib 1.3 engaging the rib 1] Obviously the handle and top being made of sheet metal will not be broken if accidentally struck and the pump top being made of sheet metal, braced by ribs formed in the metal cannot be broken by rapid movements of the pump handle, or when the pump handle is accidentally forced laterally, the pump top may be caused to bend laterally without breaking it and it could be easily straightened. All of the joints of the handle, top and link are so arranged that there will be a minimum of wear and this wear will fall upon the V the joints should become loose they may be readily tightened to take up wear by simply turning the nuts upon the bolts.
