Patented Mar. 14, 1950 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to a pick-up implement which is especially advantageous for use in picking up refuse around parks, estates, hotels, golf courses, hospitals, highways, etc.

The principal object of the invention is to provide an improved pick-up implement, which is light in weight and easy to handle, which may be readily assembled from a relatively few standard parts, and which is sturdy and dependable in operation.

A further object of the invention is to provide an improved pickup implement which will efiiciently and readily pick up all kinds of refuse and from which such refuse can be discharged easily either by means of the hand or foot of the user.

A still further object of the invention is to provide an improved pick-up implement which will pick up more efliciently a greater variety of refuse than heretofore known implements of this type, and which can be readily operated by a onearmed person to accomplish such results.

Other obects and advantages of the implement of this invention, as well as the novel details of construction thereof, will be ascertained from a perusal of the following description when read in connection with the accompanying drawings, in which Fig. 1 is a longitudinal sectional view of the implement of this invention; Fig. 2 is a left-hand end view of the implement shown in Fig. 1; Fig. 3 is a broken, detailed view of the foot release mechanism of the implement, and Fig. 4 is a sectional view taken along the line 4-4 of Fig. 3.

In the drawings, the reference numeral It designates the body of the implement which consists of an elongated metal tube approximately thirty-seven inches long and having an inside diameter of about one-half inch. The tube ID, as well as the other parts of the implement, may be made of any suitable metal, but most of such parts are preferably made of aluminum, in order to reduce the weight of the implement to a minimum. Extending axially through the bore of the tube H! is a rod or shaft I2, which is adapted to be slidably moved lengthwise within such tube to discharge refuse picked up by the implement. Threadedly engaged with the upper end of tube II] is a bushing I 5 through which extends the upper end of the rod or shaft l2. The lower end of rod 12 extends through a bushing l4 threadedly engaged with the lower end of tube ill. The bushings H and I4 serve as guides for the rod 12 whi'ch' is readilyslidable lengthwise .therethrough for a limited range of movement as will hereinafter appear more clearly. Projecting beyond 2 the external flange or shoulder 15 of bushing 14, is a threaded portion 16 on which is secured in threaded relation, an annular disc or plate 11 provided with a plurality of spikes 18 for picking up the refuse.

Mounted on rod I2 intermediate its ends is a sleeve 20 which is secured in position on such rod by means of a pair of transversely extending pins 2!, 2|. Located intermediate bushing 14 and sleeve 20 and surrounding rod 12, is a spring 22 which normally maintains the rod I2 in re! tracted position and which yieldably permits the advancement of such rod when force is applied by the user either to the knob I3 mounted on the upper end ofrod 12, or to the foot release control of the implement. The foot release control is composed of a fiat plate 23 which is mounted intermediate its ends in a transverse slot provided in rod 12 adjacent to the upper end of sleeve 20. The ends of plate 23 project outwardly through opposed longitudinally extending slots 23, 28 provided in 'tube It. Mounted on each of the pro, jecting ends of plate 23 is a foot actuatable member composed of a piece of metal sheeting which has been bent to form a pair of spaced parallelly arranged bracket portions 24, 24, and a foot rest portion 26. The bracket portions 24, 24 of each member overlies the outer side surfaces of a projecting end of plate 23 and are permanent-- ly secured to such intermediate portion of plate 23 by means of a pair of rivets 25, 25. The foot rest member is mounted on plate 23 so that portion 26 thereof, overlies the upper edge of such plate. The bracket portions 24, 24 of each member are each provided with an inner rounded bearing portion 21 whose inner peripheries ride on the outer surface of the tube 10, and together with the bearing portions 21, 21 of the foot actuatable member on the other end of plate 23, serve to facilitate the sliding action of plate 23 and to maintain plate 23 properly assembled on the device. The inner or hearing edges of the portions 21 are curved or rounded to minimize friction dur.- ing the actuation of the foot release means.

The advancing movement of rod 12 through the application of pressure to either the knob 53 or a foot actuatable member 26, causes the advancement of a metal disc 31 mounted on the lower reduced end portion 33 of rod 12. As is shown more clearly in Fig. l of the drawings, the disc 3| is secured in position on portion 33 intermediate a washer 3B which is located on such reduced portion 33 against the shoulder formed by the latter on rod 12, and a nut v32 threadedly engaging the outer end of such reduced end.199,12."

tion 33. Preferably also, disc 3| is threadedly engaged with the reduced rod portion 33. The metal disc 3| is provided with a plurality of apertures 3'! through which the spikes [8 project, and which are slightly greater in diameter than the outside diameter of the spikes [8, so that disc 3| may be readily advanced and retracted on such spikes. The spikes [8 are each permanently secured in position on'disc H in any suitable manner, such as by providing the spikes with a shoulder or transverse portion 35 which engages against the lower face of such disc and then riveting the ends 36 of such spikes against the upper face of disc l1. It is preferred that the spikes 13 be made of steel, have a length of approximately two and one-half inches and a tapered sharpened end about five-sixteenths of an inch in length. While the number of spikes may vary, to best accomplish the purposes for which the implement was devised, at least twelve spikes should be provided on disc l'l. The spikes are mounted on disc H with spacings of approximately one-quarter of an inch and are so arranged that even if one or more does not penetrate the piece of refuse to be picked up, such as twigs, such refuse will be jammed between adjacent spikes.

It will be understood from the foregoing, that the spikes l8 are'fixedly and permanently secured to the lower end of the tube Iii of the implement and that the discharge plate 3| is normally held in a retracted position adjacent to, but slightly spaced from the spike plate I! through rod I2 and spring 22. Thus, the major portion of the length of spikes I8 is normally left exposed, in order to enable such spikes to readily pick up refuse. In such use of the implement, the tube I is employed b the user as a handle. Because of the lightness and length of the implement, it may readily be inserted into bushes and refuse can be picked up from the ground without the necessity of the user stoop- -ing and bendin over. Because of the arrangement and construction of the spikes, the implement will pick up leaves and pieces of paper from as small as one-half an inch square, up to sizes having a weight of approximately two pounds. The implement is equally effective whether the leaves or paper are wet or dry, and

-to substantially larger sizes, and bones, peach pits, dry clumps of cut grass, vegetables, fruit, rags, etc. In effect, the arrangement and construction of the spikes on the implement makes it possible to pick up practically any refuse lying loose on the ground, or in or under bushes or other plants.

When the operator desires to discharge the picked up refuse from the spikes, all that is necessary is for him to either depress the knob '13 with his thumb or while holding the handle I0, depress either of the foot rests or pedals 26 with one foot. As a result of such force, the

rod 12 is caused to move downwardly against thetension of spring 22 thereby moving the discharge plate 3! towards the ends of spikes l8. -During such movement of plate 3 I, the refuse will be stripped from the spikes and discharged there 'from. Upon the release of the knob l3 or foot pedal 26 the s'pring22 will retract rod [2 and con- 'seq'uently plate 3| to their normal positions, and

ready the device for further pick-up operations, During such movement of the rod 12, it will be maintained in its axial position relative to handle Ill and will be caused to operate smoothly and with the minimum amount of friction by means of the bushings H and i4, and. sleeve 20. When either foot pedal 26 is used, the engagement of the bearing portions 21 on the exterior surfaces of the handle Ififltogether with bush ings II and I4 and sleeve 20, will prevent any tendency toward binding of the parts or the bending of rod l2 during such actuation of a foot pedal. The foot pedals 26 increase materially the versatility of the device, as they can be used interchangeably with the discharge knob 13 and also makes it possible for one-armed people, children and women to use the device with the exercise of relatively little effort. The range of movement of rod l2 and stripping disc 3!, when actuated by either the knob l3 or a foot pedal 28, is controlled by the engagement of knob 13 with bushing II and by the engagement of washer 30 with portion it of bushing M. This range of movement is preferably such that stripping disc I? will be moved from its usual at-rest position to a point just short of the outer ends of the spikes it.

While I have hereinabove described and disclosed in the drawings, a preferred embodiment of my invention, it will be apparent to those skilled in the art that changes may be made therein, without departing from the spirit of the invention or the scope of the appended claims.
