COMPUTING ATTACHMENT FOR PUMPS.

SPECIFICATION forming part of Letters Patent No. 667,452, dated February 5, 1901. Application fileds'eptember 8, 1900. Serial No. 29,374. (No model.)

To aZZ whom it may concern:

Be it known that I, LEO NIELSEN, a citizen of the United States, residing at Logan, in the county of Cache and State of Utah, have invented certain new and useful Improvements in Computing Attachments for Oil-Dispensing Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable oth- IO ers skilled in the art to which it appertains to make and use the same.

Thisinventionrelatestodispensing-pumps, and particularly to a computing attachment for such pumps.

The invention consists of a novel and peculiar scale-plate fixed to and standing vertically above the top of the pump and a price strip or band slidable over the plate and fixed to the top end of the pump-rod, so that every movement of the pump-rod will be imparted to the price-band and move it vertically over the face of the plate.

In the accompanying drawings, forming part of this application, Figure 1 is a perspective view of the upper portion of a pump with my attachment applied thereto. Fig. 2 is a front elevation of the scale-plate. Fig. 3 is front elevation of the price strip or band. Fig. 4 is a perspective view of the strip or band looking at its rear side. Fig. 5 is a similar View of a modification.

The same numeral references denote the same parts throughout the several views of the drawings.

5 The pump-head 1 has the usual dischargenozzle 2, and the pump-rod 3 works through the head and has a toothed rack 4, engaged by a suitable pinion operated by a crankhandle 5, to operate said rod in a pump-cylinder below the floor 6. To the top of the head 1 is secured the flange 7 of the computing scale-plate 8, (hereinafter to be more fully described,) so that the latter will stand vertically from the head in front of the pumprod. The price strip or band 9 (described in detail later) is arranged to encompass the scale-plate and is carried by the top end of the pump-rod.

The price computing and measuring device consists of the solid or imperforate plate 8,

(preferably of sheet metal with white enamel front face,) having a column 10, which indicates gallons, quarts, and pints, an adjacent column 11 indicating gills,and a series of verti cal lines 12, which divide the face into a series of equal spaces, each space being equally divided by horizontal lines 13, which form gages for the band 8 to work to. The lines 12 and 13 form a series of intervals 14:, each of which is occupied by numerals, which indicate the price per gallon and fraction thereof and the quantity pumped when the top edge of the price-band 8 reaches the mark in either of the said columns desired, the whole surface of the plate being uninterruptedly occupied, as above noted. Said device is completed by the band 9, preferably of the same material and finish as the plate, and is bent to encompass the plate, the ends thereof being secured together, and upon its rear side is formed a sleeve 15 to fit the top end of the pump-rod, where it is secured by a set-screw 16. The front of the band is provided with a series of lines 17, which register at all times with the lines 12, and in the space between the lines 17 are numerals indicating the price from five cents to one dollar.

Referring to Fig. 5, the price-band 9 has overlapping curved ends 18, forming a sleeve 15 by means of which and a set-screw 16 the band is attached to the pump-rod.

It is obvious that the price-band is pumped to the mark in the columns to dispense the quantity of liquid desired, and the price of said quantity is indicated by the numeral first above the figure on the price-band at which the liquid is selling per gallon. For example, if oil is selling at forty cents per gallon and a purchaser wants five gills the first numeral above the 10 on the band will be '7 after the band has been moved up to the fivegill mark in the column by pumping out five gills, the price of the latter therefore being seven cents.

In attaching the device to a pump the plate 5 is easily secured through its flange by suitable screws or rivets to the pump-head, the price-band readily slipped over the top of the plate, and the sleeve over the top end of the pump-rod, or the modified band may be bent I00 around the plate and its curved ends lapped over the pump-rod. In either case the said rod is in the rear of the plate and band, so over the plate, and the sleeve on the band in that there is no obstruction of the View of the the rear of the said plate adapted to engage numerals. a pump-rod to impart the motion of the rod Having thus described my invention, what to the band. 15 5 I claim as new, and desire to secure by Letters In testimony whereof I affix my signature Patent, is-- in presence of two witnesses.
