REVOLUTION-COUNTER.

Specification of Letters Patent.

Patented Feb. 13, 1917.

Application filed August 14, 1914. Serial No. 856,833.

To all whom it may concern Be' it known that I, VVI'LFRID PAUL HEATH, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Revolution- Counters, of which the following is a specification.

An object of my invention is to provide a mechanism which may be attached to a revolving part to count a certain number of revolutions. 1 A further object is to so construct the parts of the mechanism that the number of revolutions to be counted can be varied at the option of the operator.

A still further object is to provide an alarm means constructed as a part of the mechanism and which will be sounded upon the completion of the predetermined number of revolutions.

lVith other objects in view, which will be referred to, my invention consists in the peculiar combination and novel arrangement of parts, such as will be hereinafter more fully described in connection with the accompanying drawings and more particularly pointed out in the appended claims.

In the drawings Figure is a view in elevation of the mechanism.

Fig. 9. is a View in end elevation of the disclosure in Fig. 1.

Fig. 3 is a transverse sectional view on the line 3+3 of Fig. 1. j

Fig. 4 is a longitudinal sectional view on the line 4-4; of Fig. 1.

Fig. 5 is a fragmentary detail view of the screw threaded shaft and of parts lootiperating therewith.

In creameries where it is desired to give a predetermined number of revolutions to the churn to mix thesalt in the butter and in other connections where it is desired" to announce when a predetermined number of revolutions have been given to a rotatably mounted part, it has been customary to gage the number, of revolutions by a separate mechanism connected to be actuated by the rotation of the parts and to remain at a fixed point during the rotation of the parts, however, with such a mechanism a distinct operation and movement is required to bring part of the operator who may neglect to set the counting mechanism to the operative relation, therefore my invention is devised to be placed upon the revolving parts, as for instance upon the churn adjacent the door and will thus be accessible to the operator when other of the parts of the mechanism are adjusted, further by, securing directly to the revolving parts the operation is mad more sure and positive.

My mechanism comprises the bracket members 1 and 2 which are connected together by the rods 3 and 4'to be spaced apart, and the slide rod 5 and the gage rod 6 are mounted between the bracket members 1 and 2 to extend parallel with the rods 3 and 4. The screw-threaded shaft 7 is revolubly mounted in the bearings 8 and 9 provided in the bracket members 1 and 2 and this shaft 7 extends parallel with the slide rod 5 and the gage rod 6 and is preferably spaced equidistant between the two.

The bracket members 1 and 2 are provided with the opening 10 therethrough by which they may be attached to the revolving parts, the revolutions of which are to be counted, and the eccentrically mounted v Weights 11 are secured on one end of the screw-threaded shaft 7 to cause this shaft to be given one complete turn upon each revolution of the parts to which the mechanism is attached.

A slide bearing 12 is mounted on the slide rod 5 to have free endwise movement and this hearing 12 has an arm 13 formed to extend radially therefrom and provided with a spring clip 14 which may be brought to engage over the gage rod 5 by exerting pressure upon the arm 13. The arm 13, at a point adjacent the disposition of the screw-threaded shaft 7 has a half nut 15 secured thereon and the threads of this half nut are of a pitch to engage with and turn in the threads of the shaft 7 thus as the arm 13 is swung to a position that the spring clip 14 is engaged over the gage rod v6 this half nut is brought to a position with the threads thereof meshing with the threads of the shaft 7 and the revolution of the eccentrically mounted weights 11 will cause bracket member 1 to a position between the bracket members 1 and 2. A curved arm 18 is secured on the slide bearings 12 and as this bearing is moved along the slide rod 5 by the feeding of the teeth of the half nut 15 along the thread of the shaft 7 causes thls arm 18 to engage with the operating stem 17 and actuates the bell to permit the sounding of the alarm and the enunciation of the fact that the requisite number of revolutions have been' completed.

The gage bar Ghas a scale indicated on the upper side thereof to show the number of complete turns of the threads around the shaft 7 and this scale 19 is graduated along the length of the gage rod to permit the set- 1 ting by the operator of the arm 13 and the screw-threaded members 15 carried thereby to be moved along the extent of the screwthreaded shaft 7 and to operate the alarm pon thercompletion of any number of revo- 1 uti'onsof-this shaft 7 through the movement ofitheeccentrically mountedv weights 11. A

' gage collar 20 is mounted on the gage rod 6 to be capable of endwise sliding movement and-a set screw 21 1s provided'to set this collar the desired point and to per mit tlie'abutment of the arm 13 and the spring clip 14 thereagainst to gage a predetermined set number of revolutions without the necessity of a manual setting of the arm 14 for each consecutive operation of the mechanism.

"From the foregoing it will be seen that I have provided a mechanism which may be attached to and carried by a revolving part i to count a predetermined number of revplutions of the part and which may be set to vary the number of revolutions counted, further which causes the operation of an alarm to announce the completion of the predetermined number of revolutions and which maintains the alarm until manually cut off, which cutting off requires a stoppage of the revolving pait. Still further it will be seen that the mechanism is'composed of but few parts which are simple in construction and manufacture and which accomplish a struc ture efficient and. positive in operation and presenting very little. likelihood of disarrangement or displacement of the parts.

WVhile I have herein shown and described one specific form of my invention, it will be understood that slight changes might be made-in the form and arrangement of the several Without departing from the t'iopiesof this patent may be obtained for five cents each, by addressing the spirit and scope of my invention, and hence I do not wish to be limited thereto except for such limitations as the claims may import.

I claim 1. A revolution counter comprising a pair of brackets to be secured in a fixed relation on the revolving part, a screw-threaded shaft mounted to have turning movement in said brackets, means to transmit a complete tiirn to the shaft upon each complete revoluti on of said revolving part, a gage rod hav ing a scale thereon arranged parallel with the screw-threaded shaft and marked off in designations corresponding to the number of threads in various lengths of the shaft, a gage member provided with a screw-threaded portion to mesh with the threads of said shaft, and means to be engaged over the gage rod to hold the gage member in indicating relation with respect to the markings on the gage rod and to also hold the screwthreaded portion thereof in proper mesh with the threads of the shaft. v

A revolution counter comprising a pair of brackets to be secured in a fixed relation on the revolving part, a screw-threaded shaft mounted in said brackets to be held against endwi'se movement and to be capable of turning movement, means to cause turning of the shaft as the revolving part is turned, a gage rod mounted between said bracket members to extend parallel with the thread ed shaft, a gage member provided with a screw-threaded portion to mesh with the threads of said shaft mounted to be capable oftraveling movement along the extent oi the screw-threaded shaft, aspring member connected with the gage member to be fitted over the gage rod to hold the gage member in indicating relation with respect to the markings on the gage rod and to maintain the screw-threaded portion thereof in mesh with the screw threads of the shaft, and an adjustable member mounted on the gage rod to be moved and set at predetermined markings thereon to permit quick and repeated adjustment of the gage member to count a predetermined number of revolutions of the screw-threaded shaft.

In testimony whereof I aiiix my signature in presence of two Witnesses.
