J. W. COLE, 0F MOUNT PLEASANT, IOWA. .Lam Pam: No. 89,918, ma Mag 11, 1869.

mnovnmnn'r nv rma To all it may concern: Be itknown that I, J. W. COLE, of Mount Pleasant, in the county of Henry, and State of Iowa, have iu- Avented a new and improved Pump-Handle Bracket;

'andI do hereby declare that the following is a. full, clear, and exact description thereof', which will enable those skilled in the artto make and use the same, reference being had to theaccompanying drawings, forming part of thisspecification.

This invention relates to improvements in metallic brackets, on which the. handles of wood pumps 'are pivoted, whereby it is designed-to provide a bracket, which may be more permauentlysecnred to the stock, and which will admit of mor freedom of action for the In the accompanying drawings- Figure 1'- rcpreseuts an elevation of the top of a wood pump-stock, with my improved bracket attached,

Va part of the stock being broken away and Figure 2 represents asectionalelevation ofthe same, taken on the line a: a: of iig. 1.

A, in the drawings, represents a metallic bracket, to be secured to the side of the upper end of `a wood pumpstock,` for the purpose of aliording a bearing for the axis of the handle B the said ,pump-stock being provided with a slot, O, through which the handle projects, and intcLwhich some parts of' the bracket are ltted, for the better rsecuring of the same to the stock.

bracket open at the top, and yextend it, at the parte forsupporting thealxis D, sufficiently in an. outward direction from thevertical line,lto admit'of turning the h'andle 4down to nearly a perpendicular position, when pumping, without causing the handle tostrike the said bracket either above or below the axial pin, whereby a greater llength of stroke is admitted, by which a'correspondingly-increased amountjof water is raised, and admitting also of turning the handle down out of the way, when the pump is not used, to protect it from breakage, or from splitting the pumpstock, which often occurs, especially to pumps located in stock-yards..

I providethe side portions E of the said brackets also with extensions, F, projecting into the slot O of the pump-stock, to abontthe centre of the wall of the same, or further, ifdesired, where they terminate in right-angled flanges G, taking into a groove, H, cut into the wall of the slot C, all around the same.

And projecting from the said side-pieces E, parallel with the ri'ghtangled flanges G, I arrange the ears I, havin countersunk holes for the insertion lof woodscrews, or screwing the said ears against the outer surface of the pump-stock.

Accordingto my improvements,'I construct the Ato the distance apart of the-ears'I and the anges G.

It will be observed tirata flange, G, -is also formed on the curved bottom of the bracket, tting into the curved groove at the bottom ofthe slot f the pumpstock.

I am aware that metallic pump-handle brackets, provided with ears I, to secure them tothe outer face of the pump-stock, and open at the top, have been made, the said ears being curved, to fit the curvatures of round stocks, butthese are objectionable in the' respect that they do not aordsuiicient means for securing 'them to the stocks, the screws soon working loose under the exposure of the stocks to the alternate wet and dry con ditions.

'Moreovery the stocks must be accurately turned to the curvature of the said brackets, or they will not fit, forbidding the variations frequently necessary in the sizes of thel stecke, without the-elmployment-of-brackets having corresponding variations of curvature.

I am also aware that metallic brackets have been formed with the iianges G to 'take into grooves H, but closed at the top, andso formed that the :u ovement of the pump-handle is limited, and Apreventedyfrom being moved down to the perpendicular position, by reason of being `so closed at the top, and without the outside parallel ears I, for the purpose of serving, in conjunction with flanges G, to aord a means of more permanently securing theuLto. the stocks.

It will be observed that my improved brackets may be secured to stocks of any size, one size of bracket only being required for all sizes of stocks.

4It will alsobe observed that a square stock, having the same measurement in cross-section, affords a greater Iamount of substance than a circular one, and hence a more permanent support 'for the screws and flanges of' the bracket. i

It will also be observed that I may, if preferred, arrange the ears I to fit curved stocks.

Il claim as new, and desire to secure by'Letters Patentv -A metallic pump-bracket, held in place by laral Bauges, embracing an outer portion of the pump-stock, the inner anges Abeing fixed in a groove, the bottom part of said bracket. converging upon .the base of the slot, the pump-brake pivoted upon bearings projecting about centrally from the bracket, all arranged so as to permit the full sweep of ,the handle, fr'om a vertical position, when the piston is elevatedto an acute angle in the reverse position..
