" f GoLnnns Innoon PRACTICE TEE.
Application led September 1, 1921. Serial No. 497,569;
This invention relates to apparatus ordevices for practicing golf strokes in rooms, yards or other confined or convenient places, and has for one object toiniprove generally the simplicity and lefficiency of such devices and to provde a device or apparatus of tliis kind which will accurately rrecord thev effect oi a stroke made upon a captive golf ball.
To this end l have provided, briefly stated,
a slidable goltball-carrying rider adapted to strike a suitable impact member, and means for measuring or recording movement of said member when thus struck.
Another object ot' the invention is to provide an apparatus or device of this kind iii which noise is reduced to a minimum and durability of the device increased.
Other objects of the invention will appear as the description proceeds; and while herein details of the invention are described; the invention is not limited to these7 since inany and various changes may be made without departing from the scope ot the invention as claimed.
In the ac-coinpaning drawing, showing by way of example one ot many possible einbodinientsol:l the invention.V

`with adowiiward projec -V the rider.
Fig. 9 is a. iragmental planvof the record -ing device iii normal position; and
I Fig. l0 is aplan oiE the recordingidevice in recording or registering position.'
The various part-s or' my practice tee are niountedon a fra-ine or foundation comprising an elongated hase board or plate l() carf rying a pair of parallel bar members ll and 'l2 VYmounted on opposite sides oi said board thereby to forni va parallel channel 13 between ,said members; a rear cross piece 14 mounted on the rear vor tee-end of said board and closing the rea-r end of said channel, land a Vlforward plate l5 mounted on the forward ends oi said vboard and bar members and partially closing the forward end of said channel and-provided with a U-sliaped guide-rodieceiving-opeiiing i6 (Fig. 5).
' guide rod 2O disposed in said channel with its forward end adapted for reception said ll-shaped' opening has its rear end providedwith a pivot cap 2l fast thereon and disposed aoovea pivot lug mounted on said board in the rear end of said cliaii'- nel 13. Said cap 2l is provided with a horizontal transverse bore receiving a pivot bolt pivotally carrying links 25 pivoted to a lower bolt 26 carried` in said lug 22.
A spring 'Q8 strained between said rear.
oi said lug normally yieldably holds said rod slightly raised upon saidbolt 24 as a pivot; as sliowiiin Fig. 6.
A sleeve-shaped rider or tee carrierBl is slidably carried yon said rod and provided tion and an npstanding vbracket Ellis ing av rearwardly opening 'coiicaved ball-irrying recess (Fig.` 8) ot a Vradins slightly greater than lthe radius oi"- the goli liallt. A screw receiving opening disposed axially ci said recess 35 substantially parallel to said rod carries a -screw 39 passing throughv said screw opening into said ball' tohold the latter in place. A limiting collar 40 Vfast on said rod forward ot said compression spring 29 limits the rearward movement of A pair of parallel guide 'carrying brackets 42 `(Fig. 7) disposed in lower lateral recessesy 43 of said bar members are provided with upstanding inner webs 44 parallel tothe axis of said board at the rear position of said rider and each loosely carrying a pair of inwardly vpointing sci'ews l5 secured in *and supporting a pair of positioning guides 46 spaced apart-and yieldabiy disposed about midway between said webs and having divergent forward ends 48 (Fig. 2) for engaging said downward projection 33 on rearward movement oit' the rider, for positioning said rider with the upstanding bracket 811; standing vertical., Springs a9 compressed between said webs 44 and the adjacent guide 416 yieldably hold the guides in place.
A retaining collar (Fig. 6) fast on the forward end of said rod 2O is engaged by a spiral impact springl carried on the rod 2() and having its rear end engaged by a collar member 52 provided with a downward vextension 53 adapted for engagement with said board l0 to limit downward movement of the forward end of the rod. A cushion collar 55 of rubber or other suitable material disposed on said rod and engaging the rear face of said impact collar member receives the impact of said rider 32 when it is thrown forward under the influence of a blow by a golf club upon the rear face of the ball 36.
A metallic plate 60 (Fig. 2) is disposed over and covers a forward recess 6l (F ig. Ll)
in the bar member l2 and is provided with a narrow longitudinal slot 62 (Fig. 2) and a scale 63 along said slot calibrated to an arbitrary scale or, for instance, to indicate distances of trajectory of golf balls. A recording slide member 65 (Fig. l0) slidable fiat on the bottom of said forward recess 6l is provided with an inward projection 66, for engagement by the collar member 52, and with a longitudinal-slot 67 and a ratchettoothed edge 68 both extending substantially throughout the length of the slide member. An upwardlypand inwardly turned indicator TO on said slide member projects through said narrow slot 62 (Fig. 2) and is disposed over said scale 63.
A pair of screws 73 mounted in the bottom of said forward recess 6l (Fig. l0) are received in said longitudinal slot 6T of the recording slide member for guiding the latter in forward longitudinal movement against the action of a tension spring 74 tensioned between the rear end ofsaid slide member 65 and the rear part of said forward recess 61 for yieldably holding the slide member in rearward movement. A pawl 75 pivoted in a lateral extension 7 6 of the forward recess 61 is held yieldably engaged with said toothed edge 68 as by the spring 78, and is provided with a projecting handle 8O whereby the slide member may be released.
r[he operation of the apparatus is very simple. The apparatus is placed upon the ioor7 ground or the like, the rider moved to rearmost position, and the slide member (Fig. l0) released by movement of the pawl 75. rl`he ball 236 is then struck on its rear face with a golf club and the rider is thrown along the rod until it strikes the cushion collar and moves t-lie impact collar 52 against the action of the spring 5l,
until the reaction of the spring brings the rider to rest'after the impact collar has moved a distance depending upon the speed of the blow of the rider. its the impact moves this distance, it 4engages the projection 66 and moves the indicator TO a corto one side of the center, the rider will tend to lean to one side and the bracket 231i will engage one of the bar members ll or l2 and retard travel of the ball and cause it to record little or nothing at the scale 63. he springs 28 and 29, the rod and links 25 are so constructed that the rod is normally positioned (Fig. 6) so that a properly positioned stroke is most effective; and
in general, the indicator will record most' when the ball is struck Iin such manner as would send to greatest distances a free ball in actual play on an open green. rEhe scale 63 may, if desired, be so calibrated as to indicate such distances. ln the drawing these units of distance are arbitrarily chosen.
lil/bile in the drawing7 the device is shown very compact, and the forward recess extends as far rearward as the collar 40, there is no reason, except the desire for compactness, for making the rod 20 less than, for instance, 5 or 6 times the length of this recess.
